TEACHING PHILOSOPHY “Dr. Jeffrey Bell is a great teacher, the best for Anatomy and Physiology. He made it really easy to attend class and lab because he’s a really great lecturer.”

- Anatomy and Physiology Student, Class of 2012

A

s a biology teacher, I believe my job is to not merely present facts, but rather to explain their importance and how they interconnect to explain complex life processes. It is very easy for students to become lost in memorizing facts, missing the big picture. Like an old graduate professor always said “We all too often miss the forest for the trees”. It is crucial to not just simply memorize facts, but to develop critical thinking skills. The ability to think critically and to understand the interconnectivity of information and ideas is essential for academic success, which I stress in my courses.

In my courses, I ask my students to always be conscious of the big picture. Why is this information important?

How are these structures connected? What is the significance? When we discuss the structure of the brain, we look at how damage to specific brain region affects the body. In this way I use dysfunction to teach both function and structure and better cement in the students’ minds the complexities of the brain. For example, the students will understand the function of the corpus callosum in relaying information between cerebral hemispheres because we watched and discussed a clip about a man who struggled due to a severed one.

For the proper development of critical thinking skills it is essential to give the students an ability to assess these skills and the chance to improve on them. One of the ways I have found to do this is by asking thought provoking questions. My exams always include short answer and essay questions, which ask the students to use what they have learned in class and put it together in a novel way, to truly assess their ability to think critically. I find that the students’ skills grow throughout the semester and by the final exam they are really thinking in terms of big ideas and concepts, not just memorizing facts.

Students also need opportunities to develop skills in an environment that is not directly tied to a large summative assessment, so they can do so without the fear of failure. In all of my Anatomy and Physiology labs the sole assessment for each lab is the completion of a lab quiz. Each lab quiz is really a skill check, where the students must successfully complete the skills associated with the lab. For example, when we cover the muscular system in Anatomy and Physiology 1, the students must successfully identify fifteen muscles of my choosing before they can successfully complete the lab. When a student is ready, I ask them a random list of the muscles they have been working on the lab. The activity is not simply pass or fail, if a student struggles with identifying the muscles I will help them, or tell them to work on them some more and I will come back to them. They can also use their materials as an aid in identification. This allows them to not only work on the material, but also to assess how well they are comprehending the material in real time and make the appropriate corrections. The labs quizzes also mirror what they will be doing later, when they take the large lab practical. I only recently started using these type of lab quizzes, and have seen a letter grade improvement in lab practical grades. This points to one of the most critical aspects of teaching, that it truly is a dynamic process. I am continuing changing not only how I present information, but also how I assess the mastery of that information, including best practices that I have learned from colleagues or professional development activities.

The previous class example on teaching brain dysfunction also helps to illustrate another key component of my teaching, making learning interesting and exciting, which is essential in the sciences. It is all too easy to fall into the trap of just relaying facts, and to miss the exciting stories, processes, and explanations of the world around and inside of us. I am always trying to instill in my students that science is exciting and fun and we are all in fact scientists trying to unravel the mysteries around us. I find the best way to do this is to always relate topics to real world examples, to tell exciting and interesting stories, to present examples using available videos, animations, and virtual software, and to sprinkle in a sense of humor. I believe this makes the material more accessible to the students and makes it far easier for them to draw connections.

When we discuss the skeleton and the role of Growth hormone (GH), I illustrate its importance with two widely recognized video clips, the Lollipop Guild from the Wizard of Oz (insufficient GH) and Andre the Giant (too much GH) from the Princess Bride. The students laugh, but more importantly they instantly make the connection to Growth hormone and its functions. These types of activities facilitate learning and critical thinking, and always make the process fun. This is essential, for if students find learning fun they are more apt to become life long learners, and this really is the ultimate goal of any teacher.

I believe an open environment is the best way to harbor such learning experiences in the classroom, an environment that not only supports but encourages the diversity of ideas and the diversity of students. I create this environment by encouraging the asking of questions, discussing ideas, and sharing of information from diverse backgrounds and experiences. Questions are a great tool to begin discussions, and better hone those critical thinking skills. In biology I find that the students all have experiences or expertise to share and this is a great resource to facilitate learning. In sharing of this information, students build as sense of community within the classroom, realizing that they we are all pulling together for their success.

This past semester, while covering the digestive system, a student with Crohn’s disease shared her experience with the class, including images from her small intestine. The students asked great, intuitive questions of her, and I could really see them start to put the pieces together. I believe that fostering such exchanges enriches the experience for all involved and makes biology real and tangible, not just words on a page. In all of my teaching that is my ultimate goal, to make the topics interesting, applicable, and entertaining for if I do all of that the students will learn, and if they learn they will succeed, and their success is my true purpose and best reward.

TEACHING STRATEGIES & MATERIALS

A

s a science teacher I teach two different sections, lecture and lab, within each of my courses.

Although they cover often interrelated material, they require different organizational and teaching skills to be successful. Walking the balance between presenting information in lecture and coordinating hands on activities in lab can be difficult, but when done correctly the two nicely reinforce one another. To facilitate such a relationship in my courses I use labs to focus on identification and experimentation while presenting concepts and drawing connections during lecture.

In lectures I present information by using projected outlines with associated figures and pictures and then use the board to further explain the material, using detailed diagrams and drawings. Even though technology offers many benefits I still find using the board as an extremely effective way to cover material, only relying on my PowerPoint® slides to help orientate students to the main points while setting the “agenda” for each topic and to present pictures and videos. I find drawing on the board as a great method to draw students into a topic, something that simply talking about or presenting text on a slide will never accomplish. During lectures I continually bring in pertinent information, either directing students to current advancements in a particular field, explaining how a specific disease can alter the biology and physiology of the body, or even brining in my own research experience. I foster student interaction by asking questions that require students to synthesis information, often leading to in class discussions on a specific topic.

Labs are where I had my first teaching experience, as a teaching assistant (TA) in graduate school, and I still believe it is where I do some of my best teaching. Labs provide direct one on one interaction with students, allowing for not only direct instruction but also the ability to develop strong student/teacher relationships while helping students understand the material. When I was a TA our department head would hold a meeting with all teaching assistants each semester to go over his expectations. Always number one on his list was, “If you are sitting at the front during lab you are not teaching” and he would often walk around the building to check that we weren’t sitting in front of the lab while students worked. He wanted us to interact directly with students, to be an active participant in the lab. This is something I took to heart and continue to do to this day, never sitting during my labs, even on days where I teach six hours of lab straight. By continually moving around during lab students are more apt to ask me questions, I can quickly spot students struggling with the material, and I can offer a helpful push in the right direction when needed. This approach make my labs a true hands on experience for not only the students but also myself, and promote the idea that we are all in this together, all pulling in the same direction, towards their success.

Technology plays an important role in lab instruction, for Anatomy and Physiology labs we have a virtual dissection table (80 inch touch screen table) that students can use to explore human anatomy. Students use BodyViz速, a cutting edge virtual human dissection software, which allows students to actually fly through the human body, make annotations, and create custom content. BodyViz速 uses human imagining to present a 3D model of the human body and is used by doctors and hospitals throughout the country. The virtual dissection table also runs a variety of other softwares, including Visible Body速 and Anatomy Revealed速. Students not only enjoy using this giant tablet, but also can connect activities in lab to real human anatomy.

In both Anatomy and Physiology and Biological Principles labs we have microscope mounted cameras that connect to 60 inch high definition televisions. I use the microscope/camera set up to help students with their own microscopy work during lab. As we work through specific slides I put an example of the slide up for everyone to see, this helps them to develop a search image of what they are looking for under the microscope.

During Biological Principles 2 labs we look at living organisms under both compound and dissection microscopes I used the camera system quite often to present these organisms to the students. The camera system allows students to more quickly develop microscopy skills, which eases their apprehension in using the microscope and reduces their frustration. I use the microscope cameras to take still pictures of all the slides we look at during labs, which I post in D2L/Brightspace for students to use for exam preparation.

In designing all of my courses I have aligned learning objectives with both assessment methods and teaching and learning actives. I often provide this information to students within the course syllabus as shown for Advanced Physiology BIOL 2256 (Table 1).

Learning Objectives 1) Understand mechanisms involved in body functioning 2) Define the interaction and integration of body processes 3) Predict or evaluate the outcome of biological situations 4) Utilize current events to generate responses regarding biological and ethical issues 5) Analyze data for interpretation (ILO 2)

For each of my courses I have provided explanation on course makeup, students served, and course design/materials that differ from the general model I follow in my all my courses Examples of both formative and summative assignments for the courses detailed below can be found in Appendices 3 and 4. I have provided detailed information for my land (face to face) courses only, since they constitute the vast majority of both my teaching load and experience. I have taught Advanced Physiology (2 occasions), Anatomy and Physiology 1 (3 occasions), Anatomy and Physiology 2 (1 occasion), Biological Principles 1 (1 occasion), and Environmental Sciences (1 occasion) online. In all of my online courses I provide students with detailed week by week assignment calendars, recorded lectures, virtual laboratory activities, and a variety of both formative and summative assessments. In constructing my online courses I have followed the Quality Matters standards and rubrics.

Advanced Physiology (BIOL 2256) Advanced Physiology is a capstone type course that students take after completing Anatomy and Physiology 1 and 2. Most of the students that take Advanced Physiology are nursing students pursing their Registered Nursing degree. The course meets twice a week for lecture, with a class capacity of forty students.

Advanced Physiology focuses on several of the most complex physiological processes within the human body, often including complex biochemical pathways. For these reasons students find this course challenging so to aid students in comprehension and give opportunities to improve their mastery of the material, I provide case study activities for each of the course units. These case studies allow students to apply the material we learn in class to real world scenarios. For example, in the cardiology case study they need to interpret electrocardiograms and describe what is happening in a patient’s heart. We work on the case studies together in class, almost like a lab setting, students working in small groups as I walk around to answer questions or provide guidance. Although, the case studies are graded, they are only graded in terms of completion, if they are complete the student receives full credit. I correct any mistakes and hand them back to the student and they can then use them to prepare for the exam. Detailed keys are also posted in D2L/Brightspace for each case study. In this way the case study works as a formative assessment tool for them to gain mastery of the material they will see again on the exam (summative assessment). I have found the case studies to be a great tool in helping the students understand very complex physiological processes. An example of a case study is found in Appendix 3.

Students also write a research paper on a disease of their choice. The paper focuses not only on the aspects of the disease, but also on how it alters normal human physiology. To aid students in writing their papers, students turn in a rough draft that is edited for content and grammar, and students also take part in peer review of another student’s paper. The research paper assignment and associated rubrics can be found in Appendix 4.

Anatomy and Physiology 1 and 2 (BIOL 2252, 2254) Anatomy and Physiology 1 and 2 cover human anatomy and physiology and are prerequisites for all of the health programs on campus. The vast majority of students in both courses are health program students, with students taking the courses in series. In each course lectures contain forty-eight students and meet twice a week. Each lecture section is split into two lab sections, each meeting once a week. In lectures we focus on the physiological processes of the body, whereas in lab we cover the anatomical structures. During lecture I continually stress the importance of “form equals function”, forming connections between the structures we have learned in lab with the physiological concepts we are covering in lecture.

“I just wanted say thank you so much, you have been the best professor I have had here at Northland. Your lectures are so informative and it’s so obvious that you sincerely want your students to learn and do well in your classes. I didn’t have to take Advanced Physiology this semester but I did just because I knew you were teaching it. Thank you.” - Advanced Physiology Student, 2012

We cover a lot of material during the semester in both courses and with only two days a week to do so, I do spend quite amount of time with classic lecture. However, we do a variety of different active learning and formative assessment assignments in class. I often use short five minute quizzes to check the understanding of the material. I write five short questions on the board, have students write down answers, and then we go through them. I also use a variety of short assignments/activities as well, for example in Anatomy and Physiology I use Tissue Bingo (see Appendix 3) to help with comprehension of the tissue types in the body, and in Anatomy and Physiology 2 I use a Digestion explanation sheet (see Appendix 3) to help with understanding of enzymatic function in digestion.

In labs for both courses I use weekly skill check quizzes to help students with identification of anatomical structures and to prepare them for eventual lab practicals. For each lab the student must be able to successfully demonstrate either the skills we are learning that lab or their mastery of the material. Students have as many attempts as necessary to complete the quiz, giving them a chance to both build understanding and to practice the material while getting direct feedback. Since I have implanted these quizzes in lab, I have found that students are not only more dedicated to the material during lab but also have significantly increased their comprehension of the material. For example, in Anatomy and Physiology 1 the average on the skeleton and muscle lab practical has increased from 62% to 74%, since using these lab quizzes. Using these quizzes has had the unanticipated, yet welcomed effect of increasing both student to student and student to instructor interaction in the labs. Examples of lab quizzes for both courses can be found in Appendix 3.

Biological Principles 1 and 2 (BIOL 1111, 1112) Biological Principles 1 and 2 serve as introductory courses to the biological sciences. Very few programs on campus required these courses so the majority of students are taking these are part of a liberals art associates degree or to transfer to another institution. Each course contains twenty-four students that meet three times a week for lecture and once a week for lab.

For many students Biological Principles 1 is their first introduction to a college level science course, which for many students can be a challenge in simply keeping up with the amount of material we cover. Biological Principles 1 also covers some of the most difficult concepts in biology, including detailed biochemical pathways, cell processes, molecular biology, and evolution. I know that these topics can be difficult for students to understand so I break up lecture with a variety of different in class activities that give students amply opportunities to work through the material.

For example, when we cover cellular respiration and photosynthesis, which include memorizing long biochemical pathways, I provide students with in class worksheets on the concepts and reactions of these two processes. We spend a full lecture period working on each worksheet, where I continually walk around the room providing feedback and answering

“Jeff is an amazing instructor and is very understanding. I would recommend him for all Anatomy classes.�

- Anatomy and Physiology I Student, 2016

questions. An example of one of these worksheets is found in Appendix 3. I use other such activities through the semester, including activities on cell division, evolution (see Appendix 3), and molecular biology.

Biological Principles 1 labs use experimentation to help students conceptualize the material and processes we have covered in lecture. For every lab we either do a direct experiment or simulation, where students have to not only carry out the experiment/simulation but also explain how the results tie into the material we are covering. At the end of each of the lab students write their data on the board with each group giving a short synopsis of their results and their importance. I have found that this really helps students to draw connections between lab and lecture material and further demonstrates the importance of the scientific method and experimentation. Keeping labs topical can be an issue for any course, but by bringing in real world examples and using available scientific data my labs are continually connected to the current direction of the larger scientific field. In a lab covering phylogenetics students actually download available sequence data and construct phylogenetic trees using available software and present their results to each other, as they would if they were preparing a publication. This activity exposes students to the process of scientific data analysis and how real data can be used to answer scientific hypotheses.

Biological Principles 2 covers both the diversity of life and aspects of physiology, ecology, biogeography, and behavior.

The first half of the semester focuses on covering the many different taxonomic groups of living organisms. To further emphasize this material students also work on a semester long group project. Each group picks an organism of interest and then must find a current published scientific paper on this organism. The group then presents a 15 minute presentation to the class. The presentation includes both a background on the organism and then explains in detail all aspects of the scientific work and its merits, as they would do if presenting at a scientific meeting. The format of the presentations thus follows a scientific meeting with abstracts provided beforehand and strict timing rules during.

Students not only enjoy presenting their work, but also ask informative questions during the presentations. A portion of the final exam comes from information that is presented during the two days of presentations. For the assignment and associated presentation grading rubric please see Appendix 4.

When we finish the first half of the semester, haven finished covering all the different groups of organisms we have an in class debate, on whether birds or mammals present the pinnacle of animal evolution. The class is split in half and students use all of what they have learned to try to form the best arguments to support their side, there is really no correct answer just a fun thought exercise on what make makes a group of organisms evolutionary advanced.

During the second half of the semester in Biological Principles 2 I use a variety of demonstrations and games to help explain complex aspects of ecology and behavior. For example when we cover evolutionary ecology I use the hawkdove game that was first describe by John Maynard Smith and George Price to help explain aggressive behavior in animals (see Appendix 3). Students interact with one another as either hawks (always attack) or doves (never attack) to understand the evolutionary cost of aggression. This is not only a fun activity, but students quickly learn a rather complex example of how evolutionary forces can govern behavior.

Labs in Biological Principles 2 are structured to survey the diversity of life, with every week covering a different taxonomic group of organisms, beginning with prokaryotes and ending with mammals and birds. For each lab

“I just wanted to thank you again for an exciting and fulfilling year. I love biology and I enjoyed everything about the two biology classes.�

- Biological Principles II Student, 2011

students are provided with a list of organisms and associated structures they are responsible for identifying. We look at a variety of live and preserved specimens and perform several different dissections. To aid students in keeping track of all the material that we cover, students prepare a semester long lab notebook. In their notebook they make detailed stretched of everything they look at throughout the semester, including detailed notes and labeled diagrams. The students are really creating their own field guides during the semester while being exposed to a vast diversity of life forms and learning along the way. During the semester we have four different practical exams and the students can use their notebooks during the exam, which reinforces the effort they have put into creating them. Students hand in their notebooks at the end of each exam and I grade them for content, level of detail, and organization. Over the years students have created many exceptional notebooks, some that could easily be used to teach from. In our last lab we take a field trip to the area that I run a bird banding land in the summers and students get to help capture and band birds. In this way they get to participate in active scientific research while also having the opportunity to observe birds close up and even hold them. This field trip serves as a great capstone for the Biological Principles 2 course.

CONTENT EXPERTISE AND PROFESSIONAL GROWTH Educational Background Ever since early childhood I have been interested in science, in learning everything I could about the natural world around me. Whether it was learning about every different dinosaur or being able to identify all the different insects in my backyard, science has always been a part of my life. It was natural then that I pursued science throughout my academic career.

Although chemistry and physics at times took sway over my thoughts, it was biology that was my true calling and love.

After graduating high school, I attended the University of Wisconsin – Green Bay (UWGB) and pursued a Bachelor’s degree in Biology. While attended UWGB I took an Ornithology course, which changed the course of academic and professional career. I became engrossed in learning all I could about Ornithology and bird identification, quickly becoming involved in several research projects as an undergraduate including my own self-directed project. These research experiences drove me to continue my education and attend graduate school at North Dakota State University (NDSU), where I completed a Master’s degree in 2002 studying the acoustical behavior of Downy (Picoides pubescens) and Hairy (Picoides villosus) Woodpeckers. After completing my Master’s I worked in research for five years at the University of North Dakota (UND) and began my teaching career at Northland Community and Technical College in 2008. However, the quest to continue my academic career and further develop as a scientist pushed my back to higher education. I enrolled at the University of North Dakota in January of 2013 to pursue my Ph.D., studying avian malaria within the Brazilian Amazon. As I pursued my Ph.D. I continued to teach full time at Northland, yet I was still able to complete my degree in only three and a half years, graduating in the spring of 2016.

Going back for my doctorate has really reinvigorated my teaching. First, it has reactivated my interests in research, which has directly improved my courses. I not only keep up on new research in my field I also maintain a RSS feed of current publications from over 40 journals covering various scientific disciplines. I infuse this new information into all of my classes, keeping up with current developments, while also demonstration the importance of science as a discipline for there are always new things to learn. Second, and most importantly it has given me a great lens into what it is to be a student.

Too often as teachers we forget what it is be a student, falling into the trap of just teaching a specific way because we think it is effective, without trying to see it from the other side. As a student again I realized that some of the ways I was teaching weren’t really the best methods, for as I student I saw that they were either ineffective, frustrating, or confusing. I was also exposed to new teaching methods and strategies, many of which I found to be extremely effective. Both of these experiences DR. JEFFREY BELL | EDUCATOR OF THE YEAR PORTFOLIO

Page 8

have thoroughly changed my teaching style, and I find myself a much different and much better teacher than I was before.

I am ever adapting to new methods and strategies now, so to best serve my students, and since each class, each semester is a new experience, being willing to adapt on the fly, to teach things differently, always remembering what it was like when I was a student again.

Teaching Experience and Professional Development My first teaching experience was as a student in my high school Advanced Biology class, where I taught a lab on bacterial transformation. That opportunity sparked my interest in teaching and put me on the path to becoming a teacher.

Throughout my Master’s degree I was a teaching assistant in Anatomy and Physiology and Chordate Morphology labs and taught field courses for elementary teachers as part of the Education Program at NDSU. My first experience running an entire course was when I served as a sabbatical replacement instructor in 2003 at Northland Community and Technical College. I left teaching for five years to work on West Nile virus at UND, returning to teaching in 2008 when I accepted a full time unlimited position back at Northland. I have loved my time teaching at Northland these past ten years, and cherish the many wonderful experiences I have had as teacher. I delight in my student’s success and feel that all I do in the classroom should aid in their success. To serve this end I am continually improving as a teacher, incorporating best practices, learning from the wealth of knowledge that my colleagues at Northland possess, and attending professional development workshops. The one lesson I learned long ago and still use every day is the importance of being kind, of always being there to help students in any capacity, this is really what I feel being a teacher is all about.

Scholarly and Research Activity I have been actively involved in research since I was an undergraduate student at UWGB, but my activity has greatly increased in the past several years. I help co-run a bird banding station outside of Crookston, Minnesota each summer.

Our project is part of the national Monitoring Avian Productivity and Survivorship (MAPS) program. This projects allows me to stay active within Ornithology and bird monitoring and also exposed students at both the University of MinnesotaCrookston and Northland to aspects of scientific research. Over the years, we have trained ten students in aspects of bird banding. During my Ph.D. I worked on avian malaria within the Brazilian Amazon, sampling over four thousand birds for the presence of these parasites. I continue to work in this field, actively collaborating with colleagues both within the United States and in Brazil, presenting at scientific meetings, and publishing regularly. This past June I spent ten days in Brazil collecting additional samples. My active research program exposes my students to experiences that are similar to what they would find in a larger four year institution, yet with the benefit of a community college’s close student to teacher relationships.

To date I have authored or coauthored 16 publications and have presented at various regional, national, and international meetings (see my curriculum vitae -Section 6 and Appendix 5). Just this past September I presented at the 3rd International Congress of Parasites of Wildlife in Kruger National Park, South Africa. I attend at least one scientific meeting each year, which not only allows me to interact with colleagues, but also to be exposed to the some of the most current advances in Parasitology and Ornithology. This information is then directly incorporated back into my classes.

For example at the recent meeting in South Africa there was a symposium on human malaria, covering some of the most recent discoveries on the evolution of human malarial parasites. A month after returning from the meeting, we discussed the immune system in my Anatomy and Physiology I course and I spent half of a day’s lecture going over this material and how these new insights may help us in fighting malaria in humans. The role of education is to expose students to new information, to give them the opportunity to expand their knowledge and if I hadn’t attended that meeting, my students would not have had that opportunity.

SERVICE TO STUDENTS, PROFESSION & INSTITUTION Service to students

T

he greatest service I can give students it to prepare them to be successful, successful not only in my courses, but also throughout their career. Whether they are completing a specific degree or transferring to another institution, by aiding students in developing quality critical thinking skills I am preparing them for future academic and professional success.

My service to students extends beyond helping them to succeed academically. I truly feel that it is my duty to help any Northland student succeed, whether it is something as simple as helping a lost student find the correct classroom, helping students track down the correct office in administration, or just offering a sympathetic ear when times are tough. Student life is an important part of a student’s experience at Northland and I’ve been involved in various student life activities over the years. I have served as the co-advisor of Phi Theta Kappa (PTK) National Honor’s Society, continuing my support of this society even after stepping down as advisor, often speaking at PTK events. I have taken part in student life club sponsored study nights, where faculty are available to help students prepare for their final exams. I’ve offered my bowling talent to faculty versus student bowling fundraisers for student life clubs and have presented different topics at various student success days. I even gave the faculty address/speech at our graduation banquet on two separate occasions.

Service to profession As a discipline science only prospers if we continue to communicate our findings to the community, develop and train new scientists, and support the greater scientific community. Community outreach is an important aspect of science and is something I have been involved with since I was an undergraduate student. I have presented aspects of my research to public library groups, members of The Audubon Society, the Boy Scouts, and to elementary schools, to name a few.

Currently I co-run a bird banding station in Crookston, and over the years we have offered community open houses, where anyone who would like to learn more about birds and bird monitoring are welcome to attend.

I have directly trained almost thirty undergraduate and graduate students in a variety of different scientific techniques, being directly involved in the successful completion of five Master’s degrees and one Ph.D. degree. I have trained students locally at the University of North Dakota, the University of Minnesota-Crookston, and Grand Forks Mosquito Control, DR. JEFFREY BELL | EDUCATOR OF THE YEAR PORTFOLIO

nationally at the Field Museum of Natural History in Chicago and the Academy of Natural Sciences in Philadelphia, and internationally at the Universidad de Concepciรณn in Chillรกn, Chile and the Universidade Federal de Mato Grosso in Cuiabรก, Brazil.

I am a member of several international scientific organizations, including the American Ornithological Society, American Society of Parasitologists, Malaria Research Network, Minnesota Ornithologist Union, and the National Audubon Society.

As an active member of these organizations I support their missions and scientific outreach as well as having a voice in their direction. In this way I have direct role in supporting the importance of scientific inquiry.

I continually add to scientific knowledge in the field of Ornithology and avian parasitology by maintaining an active research program with regular publications (see Appendix 5) and presentations at scientific meetings. Since 2015 I have authored or co-authored nine publications and have presented aspects of my research at scientific conferences five times. I also regularly review scientific manuscripts for journal publication, having recently reviewed manuscripts for four different scientific journals. I also stay active in two different citizen science projects, The Christmas Bird Count (Audubon Society) and Project FeederWatch (Cornell).

Service to institution

I serve Northland Community and Technical College in several ways. First, I am an active member of several key committees in the college; Assessment and Program Review Committee, Service Learning Committee, and the Transfer Advisory Group. I have been a member of the Assessment and Program Review Committee since 2011. In my role on this committee I was one of those tasked with helping to develop and implement institutional learner outcome (ILO) assessment for the entire college. I have presented ILO assessment information and reviewed current data at several faculty inservices, provided direct aid to faculty in implementing ILO assessment in their courses, aided in development of several of the ILO assessment rubrics, and have helped facilitate several work sessions on ILO and program level assessment. I also analyze all the ILO data collected each year and summarize those results for college reporting, both internally and what will be organized for our upcoming Higher Learning Commission visit. As a member of this committee I also help review annual and five year program reviews for the many different college programs. The goal of the Service Learning Committee was to develop a service learning requirement for the college, which we have successfully implemented this year. As a faculty member of this committee I provided feedback on best practices for implementing such a requirement into the liberal arts program at our college. On the Transfer Advisory Group I provide a faculty voice in questions of course transfer and college wide articulation agreements.

Second, I have previously served faculty and the college as the president of our local MSCF chapter. As union president I worked directly with faculty and administration on a variety of important contractual issues. As union president I was also the faculty lead on the Shared Governance Council within the college, providing input from faculty into the decision making process.

Finally, I aid in the college in recruiting future students. I have been involved for the past eight years in the annual spring career expo on campus. During the expo myself and other liberal arts faculty create and present short demonstrations and activities to incoming high school students on the merits of the liberal arts program. I also represent the college in the greater community as one of its members, always explaining in detail what our college does to any that ask. This may seem like a small role, but since our college has changed names and missions many times in past, first starting as a vocational school, many in the community do not really understand what we do here. In this way I serve as a direct college recruiter, explaining the benefits of attending our college and presenting all we have to offer. Also, the hundreds of successful students that I have taught over the years are now members of our community, sharing our story and helping recruit new students to our college.

Appendix 1. Student Letters of Recommendation November 27, 2017 To the Minnesota State Board of Trustees: It is my pleasure to offer the strongest possible reference for Dr. Jeff Bell. In the fall of 2010, I began taking classes at Northland Community and Technical College, and had the pleasure of having Dr. Bell as one of my instructors. I was highly impressed with his knowledge, organization, and passion for teaching.

While taking Principles of Biology I from Dr. Bell in the fall, I quickly planned to enroll in his Principles of Biology II class as an elective the following semester. Dr. Bell made classes and lab assignments enjoyable, interesting, as well as challenging. His use of technology in the classroom and online, enhanced the overall learning environment.

Between his lectures, online quizzes and study guides, field trips, and group projects, Dr. Bell utilized an assortment of teaching and learning methods, which enriched my experience and helped me become a more successful student.

Dr. Bell constantly demonstrated his dedication to the field of biology and interest in the students at Northland College. On several occasions, I met with him in his office, or in passing, to ask questions or get advice, and he was always approachable, friendly, and helpful. Dr. Bell also served as a Northland College faculty advisor for a student organization I was involved with, and was an invaluable resource to myself and the other students who served on the committee.

After I graduated from Northland Community College, I transferred to the University of North Dakota where I went on to earn both my bachelor and master degrees. I believe many of the habits and skills that helped me further my education, I learned at Northland, and several of them I learned from Dr. Bell. I was excited to learn that Dr. Bell was also at the University of North Dakota working on his Ph. D, and we even got a chance to have lunch together and catch up once and a while.

It was my privilege to have Dr. Bell as an instructor, and my honor to call him my friend!

If there is any need for further information, please feel free to contact me at (701) 7413474. I would be delighted to share any additional insights with you regarding Dr. Bell.

Sincerely, Matt Mutzenberger

DR. JEFFREY BELL | EDUCATOR OF THE YEAR PORTFOLIO

Good Afternoon Dr. Castle, Please allow this letter to serve as a letter of recommendation for Dr. Jeffery Bell who is nominated for the Minnesota State Colleges and Universities Board of Trustees Award for Excellence in Teaching.

I have known Dr. Bell for nearly six years now. I was a student at Northland Community & Technical College, and while our paths did cross in the classroom, Dr. Bell and I quickly became acquainted because he was one of the most adept, friendly, and competent teachers I have ever met – and needed! I also worked with him when he was co-advisor for the Phi Theta Kappa Beta Nu Chapter and I was our vice-president at the time. As a result it has been my privilege and honor to watch Dr. Bell’s techniques to motivate students to become better leaders in society and successful members of our student body. Dr. Bell is well-known throughout the College for not only his teaching methods, but also his willingness to help students, determination to solve any challenge presented to him, and also his ever-present smile and enthusiasm.

Dr. Bell has proven himself to be a dedicated instructor. He also cares about “quality” and “integrity”! I believe all of Dr. Bell’s educational and life’s experiences demonstrate that he is an effective leader and an active participant in his students’ development. He actively seeks any answers his students’ need to understand a concept, or situation. In my nearly 20 years of learning from the secondary level to graduate-level, I have met only a few like Dr. Bell who have demonstrated such an eagerness and dedication and commitment to teaching. I believe Dr. Bell is one of people who influenced me to further my education and that is why I am currently involved in graduate school. I personally his excellence in teaching makes him an excellent candidate for your award based on.

Throughout our shared time together, I have been very impressed with Dr. Bell’s communication, class presentation, and organizational skills. He also possesses a wonderful sense of humor coupled with a high degree of professionalism and a quick mind. He appears to be quite serious about becoming the best teacher so as to benefit his students. Dr. Bell cares about what he does and that loyalty and attention to detail shows in many of the experiences we have shared.

I believe Dr. Bell’s knowledge, background, and teaching experiences, including his excellent people skills and willingness to teach will make him the best nominee for the Minnesota State Colleges and Universities Board of Trustees Award, please do not hesitate to contact me.

Sincerely, Hussein Abd, Former student at Northland Community and Technical College

To the Minnesota Board of Trustees: The topics covered in Dr. Bell’s classes are far beyond my comprehension‌ but thanks to Jeff I was able to understand them. I was fortunate enough to have him for anatomy and physiology I and II and also for advanced physiology. I was impressed by his down to earth demeanor and the fact that if I had any question about anything in the human body no matter how strange or obscure he was able to answer it, he knows all the answers. I find that to be a very valuable quality to have in an instructor. He has an impeccable way of making complicated things easy to understand. Educators like him are few and far between I am grateful to have had him be a part of my journey to becoming a nurse.

With warmest regards Anna Rousseau

Modeling Agnostic Behavior In this activity we will be looking at how animals interact aggressively (agnostic behavior) with one another in competition for resources. To understand agnostic behavior we will be modeling agnostic behavior, with each of your acting as one of two behavioral extremes, Dove or Hawk. A Dove is an individual that only displays and never attacks. A Dove will display until the opponent flees or attacks. If the opponent attacked the Dove always flees. A Hawk will always fight and never displays. A Hawk fights until either the opponent is injured, killed, or flees, or the Hawk is injured itself. The rules for the game are below.

Payoffs/costs Winning = 50 points Losing = 0 points Injured = -100 points Long display (2 doves) = -10 points Rules for interactions Hawk vs Dove = Hawk gets 50 points/ Dove gets 0 points Dove vs Dove = Winner gets 40 points/Loser gets -10 points Hawk vs Hawk = Winner gets 50 points/Loser gets -100 points Playing the game

50/50 chance determined by coin flip

1) Decide whether you will be a Hawk or Dove and write that choice on the front of the note card provided.

2) Interact with another student, you will both present your card and following the scoring rules above. If you are the same type, 2 Doves or 2 Hawks, flip a coin to determine the winner.

3) Write you score for this interaction on the back of the card.

4) Repeat with 9 other students and then write your score on the board along with your name and weather you were a Dove or Hawk. (If you have a negative score you are dead) 5) Now play the game again, interacting with another 10 students, you may change your status or stay the same, your choice.

Case Study 1 Below are four (4) narratives about heart physiology, answer the questions associated with each.

You may work in small groups, but make sure that each team member turns in a sheet with their name on it. Feel free to ask questions to clarify any of the information below.

1:

Frank an otherwise healthy young man of 24 goes into his doctor’s office complaining of experiencing periods of rapid heartbeat accompanied by extra strong (thumping) beats.

At the time of the visit his ECG is normal and his blood pressure is 115/75. The doctor asks Frank some general history questions and finds out that he does not drink or smoke, has no history of heart disease in his family, but for the past few months has been under a lot of stress (new baby, new job) and hasn’t been sleeping and has been drinking more coffee than normal. The doctor asks Frank to come in tomorrow for a stress test to try to determine what is going on.

Question 1: What do you think the doctor suspects is affecting Frank’s heart? Defend your answer?

Frank comes back the next morning and undergoes a stress test, which produces the phenomenon that Frank was complaining about. After looking at the results of the ECG and the stress test, the doctor tells Frank that his heart overall looks healthy, but his ECG showed several PVC’s, due to a ventricular ectopic focus.

Question 2: What is an ectopic focus and why is it producing the increased heart rate and thumping heart beat? What is a PVC and how is it caused by an ectopic focus?

DR. JEFFREY BELL | EDUCATOR OF THE YEAR PORTFOLIO

Page 36

Question 3: Draw an ECG that would represent what is going on in Frank’s heart.

Question 4: What do you think is causing Frank’s problems; do you think it is anything serious? If you were Frank’s doctor what advice would give him?

2:

Mary a 55 year old mother of 6 is taken to the emergency room complaining of heart palpitations, chest pain, and an overall feeling of being light headed. In the ER her heart rate is highly elevated, but her pulse is both weak and does not match her heart rate.

Question 1: With the information provided, what do you think might be ailing Mary?

What could be causing her weak pulse, what is the term given when pulse and heart rate do not match?

Mary is hooked up to the ECG, which shows both a rapid heart (155 b/min) and irregular heart rate. The incoming cardiologist looks at the lack of true P waves on the ECG and immediately knows what is causing Mary’s symptoms.

Question 2: What does the P wave on an ECG represent? What would the lack of true P waves represent; what is afflicting Mary?

Question 3: How would your diagnosis cause the symptoms Mary is experiencing, be sure to explain the rapid heart rate, light headedness, and miss matched pulse and heart rate.

Page 37

DR. JEFFREY BELL | EDUCATOR OF THE YEAR PORTFOLIO

Question 4: Draw and ECG that would represent what is going on in Mary’s heart.

3:

Mark a 82 year old man retired teacher is rushed to the hospital complaining of chest pain, pain radiating down his left arm, shortness of breath, and nausea.

Question 1: What do think is causing Mark’s symptoms.

Below is Mark’s ECG taken at the hospital.

Question 2: Does this ECG support your diagnosis above? What is abnormal about this ECG?

Soon after entering the hospital Mark regresses into ventricular fibrillation, but fortunately heart defibrillation is able to restore a sinus rhythm. After several days in the hospital Mark is able to return home.

Question 3: What causes ventricular fibrillation and why is it so dangerous? How does heart defibrillation restore normal heart rhythm?

DR. JEFFREY BELL | EDUCATOR OF THE YEAR PORTFOLIO

Page 38

Question 4: Draw and ECG that would represent what was going on in Mark’s heart during ventricular fibrillation.

4:

Sally a 35 year old sky diver goes to the doctor complaining of periods of light headiness and a slower than normal pulse. During a stress test the doctor notices some abnormalities with her ECG. The doctor tells Sally she has a 2:1 AV nodal block.

Question 1: What is the function of the AV node in the heart, and where on an ECG is the activity of the AV node seen?

Question 2: What abnormalities would a 2:1 AV nodal block cause on an ECG? What does 2:1 mean? Why is her pulse rate slowed? What is the name given to a slower than normal heart rate?

Question 3: Draw an ECG representing what is happening in Sally’s heart.

After consulting with Sally the doctor decides that an internal pacemaker is probably the best treatment for her condition. The procedure is scheduled for next month.

Question 4: Why is the doctor suggesting implanting a pacemaker? How will this help Sally’s condition?

Appendix 4. Summative Assessment Examples with Associated Rubrics Biological Principles 1: Project/Presentation This is an opportunity to explore your interest in a particular taxon of plants or animals, many of which we just don’t have the time to cover well, or at all. The purpose of this exercise is both for you to learn more about a specific taxon and for the class to be exposed to a greater diversity of organisms.

Working in groups of 2 to 3 you will pick a taxon of interest, and find a relevant scientific article (must be published in a peer-reviewed journal). Your taxon can be a single species, genus, family, or order. You will need to get prior approval of your taxon of interest and journal article with me. Upon approval you will need to either send or give me a copy of your paper. You will then do some background research on your taxon, and use that information to better present the findings of research article to the class. Your background research should include several sources, additional journal articles, textbooks, online resources. It should not only include information from one source, ie.

Wikipedia.

You will be responsible for a 10 minute PowerPoint presentation, in which you will present a general introduction to the taxon, and the go over the findings of the research article. An outline of what your presentation should include is below.

Format of Presentation: 15 minutes (5 minutes for questions at the end) 1. Introduce the taxon and general subject of the paper a. general background on taxon (phylogeny, ecology, anatomy/physiology as it relates to article). Use the literature cited in the article as a guide. b. explain any specialized concepts or terms that are important to the article 2. Summarize the chosen paper – methods, results as presented (include tables and figures), and conclusions the authors reach.

3. Provide your opinion of the research and outcomes, both positive and negative. What does the research add to our knowledge?

Your presentation should incorporate any multimedia that you can locate, pictures, videos, sounds, the more the better. Your PowerPoint slides should be more of Page 41

a slide show, with only enough text to make major points, this is not a lecture or book report, but a presentation, it should be entertaining and insightful. These presentations are meant to spark discussions and the members of the class who are not presenting are expected to ask thoughtful questions of the presenters. I will present an example so everyone gets an idea of what I’m looking for.

The following are to be prepared and turned on the day of the presentations.

1. A copy of either an outline or the notes for your presentation; these may be rough notes, hand-written.

2. An annotated bibliography of your references, see example below, must be typed.

3. Three questions about your presentation that can be included on the final, can be in any format. Provide the answers as well, must be typed.

4. A breakdown of what each person was responsible for, must be typed and signed by each of the group members.

Examples of annotated bibliography: Brown, J. L. 1964. The evolution of diversity in avian territorial systems. Wilson Bull.

76:160-169. Detailed discussion of territorial systems and presents the idea of economic defendability for the first time.

The purpose of this exercise is for you to learn more about a specific disease/disorder and further emphasis the importance of human physiology in maintaining homeostasis You will pick a human disease/disorder of your choice, and then do background research to construct a well written research paper. You will need to get prior approval of your disease/disorder with me before beginning your research. Send me an email with your topic along with at least one source you are considering. I will not accept a draft unless your topic has been approved. Your background research will include several sources, journal articles, textbooks, online resources, and you are required to include at least 3 sources, one of which can be your textbook. You will be expected to cite your sources both within the paper and in a work cited section, according to APA style, examples of both are below. We will be going over this more in detail in class as well. Even though you are using outside sources you are expected to do your own work. Material from outside sources should either be put in your own words or if that is not possible placed in quotations, see examples below. Plagiarism whether intended or not is not tolerated in any academic setting and will result in a zero on the assignment.

Your paper will cover all the major aspects of the disease/disorder, including its cause, its effect on physiological processes, symptoms, diagnosis, prognosis, treatment, and current/future research. Since you will eventually become an expert on your disease/disorder I would suggest picking something you are interested in or wish to learn more about.

According to Klatt (1995), “Eastern Screech-owls form long term pair bonds that last longer than a single breeding season� (pg. 123). It is not known how this may relate to other owl species.

Long Quotation (as free standing block, no quotation marks) Although many studies have looked at periodicity in human filarial nematodes, few have studied if it exists in other host species.

According to Vaughan and Tkach (2006): The lack of knowledge on non-human filarial nematodes is both puzzling and troubling since they are extremely common in almost all taxa and may play a role in vector-borne diseases. Our work with Mansonella ozardi and Dengue virus shows the potential for these parasites to alter transmission ecology of a vector- borne virus. To better understand this phenomenon a better understanding of the periodicity of these parasites is needed. (pg 245) Examples of work cited: Journal Brown, J. L. 1964.

Research Paper West Nile Virus in Host-Seeking Mosquitoes within a Residential Neighborhood in Grand Forks, North Dakota JEFFREY A. BELL, NATHAN J. MICKELSON, and JEFFERSON A. VAUGHAN

ABSTRACT West Nile virus (WNV) was first recovered in North Dakota near the city of Grand Forks in June 2002. During 2002, 2003, and 2004, we collected mosquitoes from Grand Forks using Mosquito Magnet™ traps and tested them for WNV. The seasonal abundance, species composition, and reproductive status of female mosquitoes were correlated with local environmental temperature and state surveillance data on WNV to determine the factors affecting local transmission of WNV. Over 90% of the mosquitoes collected were Aedes vexans, Ochlerotatus dorsalis, and Culex tarsalis, but WNV was detected only in Cx. tarsalis. Average summertime temperatures and relative abundance of mosquitoes were highest in 2002 but no WNV-positive mosquitoes were detected until the following summer. In 2003, nulliparous Cx. tarsalis appeared in mid-June (first summer brood), and parous Cx. tarsalis appeared in mid-July. The first WNV-positive pool occurred 21 July, and minimum daily infections rates increased thereafter until 27 August. The minimum infection rate (MIR) for Cx. tarsalis during the season was 5.7 infected mosquitoes per 1,000 tested, with the highest infection rates occurring at the end of the season as Cx. tarsalis populations started to decline. Mid-to-late August was identified as the period of highest risk for being bitten by a WNV-infected mosquito in Grand Forks during 2003. In 2004, viral activity in Grand Forks was low, due to very cool temperatures throughout the summer. To examine the genetic diversity of the 2003 WNV isolates from Grand Forks, we sequenced a 366-nucleotide region of the capsid and premembrane gene. Thirteen (46%) of the 28 WNV isolates contained at least one nucleotide substitution when compared to the homologous region of the progenitor WN NY-99 strain, and seven of these 13 substitutions coded for amino acid changes. Thus, WNV is established in North Dakota, it appears to be evolving and it is vectored primarily by Cx. tarsalis.

INTRODUCTION

G

RAND FORKS, North Dakota (latitude 47.93N; longitude 97.03W) is located on the Red River of the North that forms the border between North Dakota and Minnesota. The river lies within a wide basin, the Red River Valley, formed by the prehistoric, glacial Lake Agassiz. The topography is flat and the dense soil formed from the ancient lakebed is fertile

but does not drain well. As a result, there is a considerable amount of standing water throughout the valley in the form of ditches and marshes, creating enormous breeding habitat for mosquitoes. Each summer, the valley produces high numbers of mosquitoes, primarily inland floodwater species (e.g., Aedes vexans and Ochlerotatus dorsalis) and Culex tarsalis (Deckart 1995). Mosquito nuisance within this region can hinder human enjoy-

Abstract Background: The population dynamics of Plasmodium sporogony within mosquitoes consists of an early phase where parasite abundance decreases during the transition from gametocyte to oocyst, an intermediate phase where parasite abundance remains static as oocysts, and a later phase where parasite abundance increases during the release of progeny sporozoites from oocysts. Sporogonic development is complete when sporozoites invade the mosquito salivary glands. The dynamics and efficiency of this developmental sequence were determined in laboratory strains of Anopheles dirus, Anopheles minimus and Anopheles sawadwongporni mosquitoes for Plasmodium vivax parasites circulating naturally in western Thailand.

Methods: Mosquitoes were fed blood from 20 symptomatic Thai adults via membrane feeders. Absolute densities were estimated for macrogametocytes, round stages (= female gametes/zygotes), ookinetes, oocysts, haemolymph sporozoites and salivary gland sporozoites. From these census data, five aspects of population dynamics were analysed; 1) changes in life-stage prevalence during early sporogony, 2) kinetics of life-stage formation, 3) efficiency of life-stage transitions, 4) density relationships between successive life-stages, and 5) parasite aggregation patterns.

Results: There was no difference among the three mosquito species tested in total losses incurred by P. vivax populations during early sporogony. Averaged across all infections, parasite populations incurred a 68-fold loss in abundance, with losses of ca. 19-fold, 2-fold and 2-fold at the first (= gametogenesis/fertilization), second (= round stage transformation), and third (= ookinete migration) life-stage transitions, respectively. However, total losses varied widely among infections, ranging from 6-fold to over 2,000-fold loss. Losses during gametogenesis/ fertilization accounted for most of this variability, indicating that gametocytes originating from some volunteers were more fertile than those from other volunteers. Although reasons for such variability were not determined, gametocyte fertility was not correlated with blood haematocrit, asexual parasitaemia, gametocyte density or gametocyte sex ratio. Round stages and ookinetes were present in mosquito midguts for up to 48 hours and development was asynchronous. Parasite losses during fertilization and round stage differentiation were more Page 1 of 17 (page number not for citation purposes)

West Nile Virus Epizootiology, Central Red River Valley, North Dakota and Minnesota, 2002–2005 Jeffrey A. Bell,* Christina M. Brewer,* Nathan J. Mickelson,* Gabriel W. Garman,* and Jefferson A. Vaughan* West Nile virus (WNV) epizootiology was monitored from 2002 through 2005 in the area surrounding Grand Forks, North Dakota. Mosquitoes were tested for infection, and birds were surveyed for antibodies. In 2003, WNV was epidemic; in 2004, cool temperatures precluded WNV amplification; and in 2005, immunity in passerines decreased, but did not preclude, WNV amplification.

W

est Nile virus (WNV) is a flavivirus with an enzootic cycle that involves primarily mosquitoes and birds in the order Passeriformes. Since its introduction into the northern prairies of the United States in 2002, WNV has flourished. In 2003 and 2005, the prairie states of North Dakota, South Dakota, and Nebraska recorded the highest incidence of cases in humans (per 100,000 county residents) for the entire United States (1). Although WNV is still new to the region, the ecology of the northern prairie seems to offer favorable conditions for its continued enzootic transmission. This report chronicles the initial establishment of WNV within the central Red River Valley of eastern North Dakota and northwestern Minnesota (Figure).

The Study Host-seeking mosquitoes were collected in and around Grand Forks, North Dakota, by using Mosquito Magnet traps (American Biophysics Corp., North Kingston, RI, USA) for 4 transmission seasons, from early summer 2002 through fall 2005. Mosquitoes were sorted by species and tested for WNV by using reverse transcriptase PCR assays.

WNV was detected only in Culex tarsalis (2).

Passerine birds in and around Grand Forks were surveyed for antibodies to WNV for 3 transmission seasons: *University of North Dakota, Grand Forks, North Dakota, USA

June 24–October 27, 2003, April 4–July 7, 2004, and May 17–August 11, 2005. In 2003 and early 2004, birds were captured by using mist nets, blood (<0.1 mL) was obtained by brachial venipuncture, and birds were released. Later in 2004 and in 2005, necropsies were performed on dead birds. Blood spots were placed on filter paper and later eluted in 250 µL saline. Samples were tested for anti-WNV antibodies by using a qualitative epitope-blocking ELISA (3).

This is the first report of seroprevalence of WNV in passerines in the northern prairies. A total of 277 birds (11 species) were tested (Table 1). In 2003, seroprevalence was relatively low (17%). The first seropositive bird was captured July 24, 2003, 4 days after the first WNV-positive pool of Cx. tarsalis was detected (2). Most seropositive birds (11 of 14) were collected in September, when migratory species were leaving and vector populations were waning. Thus, a lag occurred between peak abundance of infected vectors in mid- to late August 2003 (2) and seroconversion of passerines. Seroprevalence rates were significantly higher in 2004 and 2005 than in 2003 (Table 1, Fisher exact tests, p<0.0001) and were higher than most seroprevalences reported for passerines in the eastern and southeastern regions of the United States (4–6). All passerine species sampled in 2004 and 2005 contained seropositive birds, which indicated that all these species were preyed on by vectors regardless of differences in their nesting habitats (e.g., cattail marshes, peridomestic). American robins, common grackles, and red-winged blackbirds showed increased seroprevalence from 2003 to 2004. High seroprevalence was maintained in passerines in 2005 despite low WNV activity (i.e., low natural boosting) during 2004 (2), which suggests that passerine immunity to WNV may last longer than a single season (7,8).

Surprisingly, American crows had a high seroprevalence to WNV. Previous laboratory and field studies have indicated that most American crows die so quickly from WNV infection that they never have time to seroconvert (9–11). Why crows in the Red River Valley survive WNV infection is not known. One possibility is that WNV has undergone genetic changes with a concurrent loss in virulence as it spread westward from forest ecosystems with

Passage of Ingested Mansonella ozzardi (Spirurida: Onchocercidae) Microfilariae Through the Midgut of Aedes aegypti (Diptera: Culicidae) JEFFERSON A. VAUGHAN,1,2 JEFFREY A. BELL,1 MICHAEL J. TURELL,3

ABSTRACT When virus and microÞlariae are ingested concurrently by a mosquito, microÞlariae (mf) may penetrate the mosquito midgut and introduce virus directly into the mosquito hemocoel, allowing mosquitoes to become infectious much sooner than normal and enhancing transmission of viruses by mosquitoes. Mansonella ozzardi (Manson) is a benign Þlarial nematode parasite of humans in Latin America and is transmitted by black ßies (Diptera: Simuliidae) and biting midges (Diptera: Ceratopogonidae). Because M. ozzardi and dengue are sympatric, we wanted to know whether M. ozzardi mf had the ability to penetrate the midgut of Aedes aegypti (L.) (Diptera: Culicidae) and thus play a potential role in the enhancement of dengue transmission. To test this, the F1 progeny from locally collected Ae. aegypti were fed on M. ozzardi-infected human males in an endemic village in northern Trinidad. Mosquitoes were dissected at various times after feeding and examined for mf in the midguts and thoraces. MicroÞlariae penetrated the midguts of 43% of 63 mosquitoes that ingested mf. Overall, 11% of mf penetrated the midgut by 17 h after being ingested. The intensity of midgut penetration was positively correlated to the numbers of mf ingested. Because midgut penetration is a key requirement for mf enhancement to occur, the potential exists that M. ozzardi could be involved in the enhancement of dengue virus transmission.

KEY WORDS Mansonella ozzardi, Aedes aegypti, dengue, microÞlaria, transmission

Concurrent ingestion of microÞlariae (mf) and arboviruses by vector arthropods has been shown to result in signiÞcantly more efÞcient transmission of the virus than when the same dose of virus was ingested alone (Mellor and Boorman 1980; Turell et al. 1984, 1987; Zytoon et al. 1993; Vaughan and Turell 1996; Vaughan et al. 1999). This has been referred to as microÞlarial enhancement of arboviral transmission. As part of their normal developmental cycle in a vector, most mf species penetrate the vector midgut after being ingested and migrate to a preferred site of development (e.g., ßight muscle and fat body). If a microÞlaremic host is also viremic when fed upon by a vector, then there is the possibility that penetration of the midgut by mf will allow some of the ingested virus to enter directly into the vector hemocoel. The facilitated movement of virus directly into the hemocoel can have two important epidemiological consequences.

First, it can increase vector competence by allowing virus to bypass both midgut infection and midgut escape barriers (Chamberlain and Sudia 1961, Kramer et al. 1981), transforming otherwise incompetent vector species into competent vector species and thus increasing the number of vector species involved in an arbovirus transmission cycle. Second, mf enhancement can accelerate arboviral development within a vector and shorten the time required for a virus-exposed mosquito to become infectious (i.e., shorten the extrinsic incubation period [EIP]). Because the EIP affects transmission exponentially (MacDonald 1952), small reductions in EIP can lead to large increases in vectorial capacity, even within natural arbovirusÐvector systems.

Most laboratory studies of mf enhancement have used various arboviruses with Brugia spp. mf and Aedes/Ochlerotatus spp. mosquitoes as experimental model systems (Turell et al. 1984, 1987; Vaughan and Turell 1996; Vaughan et al. 1999). But the concept of mf enhancement could apply, in theory, to almost any ÞlarialÐvector system (Mellor and Boorman 1980) where Þlarial and arboviral infections are sympatric.

An important consideration is whether the mf can penetrate the midgut and enter the hemocoel and thus allow the virus to bypass the midgut. Further development of the parasite is irrelevant, i.e., a mosquito species does not have to be a competent vector of

YELLOW-BREASTED CHAT IN POLK COUNTY â&#x20AC;&#x201D; The Red River Valley Natural History area sits quietly nestled amongst land owned by the Northwest Research and Outreach Center and is used as an outdoor classroom and lab by the University of Minnesota, Crookston (UMC). This educational and interpretive site lies west of campus and hosts abandoned gravel pits, tracts of restored prairie, and aspen stands. Laura Bell, UMC Natural Resources Technician and Naturalist monitors various biological aspects of the 85-acre tract. On Sunday 20 May 2007, Laura and her husband Jeff, an ornithologist at the University of North Dakota, were mist-netting birds as part of a yearly inventory of the migratory birds that use the area as important stopover habitat. That morning they caught a variety of neotropical migrants typical of the area during spring migration. At approximately 8:50 A.M. when checking the second of the four mist nets, Jeff encountered an uncommon bird for this area, a Yellow-breasted Chat (Icteria virens). The male chat, (determined by cloacal protuberance), was in excellent condition and after a quick extraction and a few photos it was released. The presence of this Yellow-breasted Chat marks the first record for Crookston and only the second record for Polk County, the first record occurring in Fosston in May 1921 (Janssen, R. B., 1987. Birds in Minnesota). Mist netting inventory studies such as this can serve as a good indicator of the vagrancy of certain migratory species during both spring and fall migrations. Laura E.

Abstract

Two new species of Camallanus are described from Australian freshwater turtles. Camallanus beveridgei sp. nov. is reported from Elseya dentata in Northern Territory. It differs from other species of the genus parasitic in turtles by several characters including the shape of the median ridge in the buccal capsule and the position of the anterior pair of caudal papillae in males. Camallanus sprenti sp. nov. is reported from Elseya latisternum (type host) and Emydura krefftii in northern Queensland. It is closely related to Camallanus tuckeri, and differs from the latter species in possessing a shorter oesophagus. We summarize data on morphology, distribution and specificity of 5 known Camallanus spp. from Australian turtles and provide a key for their identification. Sequence comparison of more than 500 base pairs at the 5’ end of the nuclear 28S rDNA gene confirms the status of C. sprenti and C. beveridgei as new species. Camallanus sprenti differs from the other 4 species of Camallanus from Australian turtles by 16–59 bases (3.1–11.5%) while C. beveridgei differed from the other 4 species by 23–60 bases (4.5–11.6%).

Phylogenetic analysis demonstrates close interrelationships among C. tuckeri, C. sprenti and C. beveridgei, the three species with most similar buccal capsules.

Introduction Camallanidae Railliet et Henry, 1915 is a globally distributed nematode family consisting primarily of parasites of fishes.

Some species are known from amphibians and reptiles, including turtles (Ivashkin et al. 1971, Petter 1979). Yeh (1960) erected the genus Serpinema Yeh, 1960 which includes turtle parasites with characteristic buccal capsules that possess a gap between the dorsal and ventral groups of ridges on each of the buccal capsule valves. Baker (1983) described Camallanus chelonius Baker, 1983 from the South-African side-necked turtle Pelusios sinuatus (Pleurodira, Pelomedusidae). This parasite lacked such a buccal capsule gap and was, therefore, allocated into Camallanus Railliet et Henry, 1915. Camallanus chelonius was later reported from the Australian side-necked turtles El. latisternum and Emydura macquarii in Queensland (Ferguson and Smales 1998). However, Rigby et al.

(2008) determined that this report was the result of misidenti-

fication and described two Camallanus species, C. nithoggi Rigby et Sharma, 2008 and C. waelhreow Rigby et Sharma, 2008, parasitizing El. latisternum, Emydura krefftii and Em. macquarii in Queensland. Recently, Kuzmin et al. (2009) described C. tuckeri Kuzmin, Tkach et Snyder, 2009 from Emydura australis and Chelodina burrungandjii in Western Australia.

As part of a survey of the parasite fauna of Australian freshwater turtles we have identified two previously undescribed Camallanus species, one from El. dentata in Northern Australia, and another from El. latisternum and Em. krefftii in Queensland. In addition, we have found C. waelhreow and C. nithoggi from previously unreported hosts and localities.

The present work includes descriptions of the new species as well as a survey of known records of all 5 species of Camallanus from Australian freshwater turtles and a key to their identification.

ABSTRACT Vertebrate reservoirs of arboviruses are often infected with microÞlariae (MF). Laboratory studies have shown that MF can enhance the infectivity of arboviruses to mosquitoes. Soon after being ingested, MF penetrate the mosquito midgut. If the host blood also contains virus (i.e., vertebrate is dually infected), penetrating MF may introduce virus into the hemocoel. This can transform otherwise virus-incompetent mosquito species into virus-competent species and simultaneously accelerate viral development, allowing mosquitoes to transmit virus sooner than normal. This phenomenon is termed microÞlarial enhancement of arboviral transmission. The prevalence of MF is very high in many passerine populations in North America. Therefore, we investigated if microÞlarial enhancement could have facilitated the establishment and rapid spread of West Nile virus (WNV) across the mid-western United States. Our investigations revealed that mosquitoes, WNV, and passerine MF do interact in nature because; 1) 17% of 54 common grackles (Quiscalus quiscula L.), 8% of 26 American robins (Turdus migratorius L.), and 33% of three eastern kingbirds (Tyrannus tyrannus L.) were concurrently microÞlaremic and seropositive to WNV; 2) feeding activities of mosquitoes overlapped temporally with the appearance of MF in the blood of common grackles; 3) mosquitoes fed on common grackles and American robins in nature; and 4) mosquito ingestion of two taxonomically distant species of passerine MF (i.e., Chandlerella quiscali and Eufilaria spp.) resulted in penetration of mosquito midguts. To estimate the theoretical effect that MF enhancement could have on WNV transmission in areas of high MF prevalence, vectorial capacity values were calculated for Culex mosquitoes feeding on common grackles, whereby MF enhancement was either invoked or ignored. For Cx. pipiens, vectorial capacity increased over three-fold when potential effects of MF were included in the calculations. For Cx. tarsalis, the effect was less (i.e., 1.4-fold increase). Closer attention should be paid to the potential of MF to enhance mosquito transmission of arboviruses.

DeÞning vector competence is fundamental to understanding arboviral transmission cycles. Not every arthropod species can transmit every arboviral species, meaning there can be barriers to the infection process.

The most important is the “midgut barrier” (Chamberlain and Sudia 1961). Ingested virus may either be unable to enter the arthropod midgut cells because of a receptor-ligand incompatibility ( midgut infection barrier) or, once inside, virus may be unable to disseminate from the midgut to the hemocoel ( midgut escape barrier) (Kramer et al., 1981, Hardy et al., 1983). In many cases, once the midgut barrier is overcome, viral infection of the salivary glands and subsequent transmission ensues. Thus, any mechanism 1 Department of Biology, University of North Dakota, 10 Cornell St., Grand Forks, ND 58202-9019.

that effectively bypasses midgut barriers will greatly increase the potential transmission of arboviruses by vectors.

The standard way to identify midgut barriers is to feed suspected vectors on viremic blood. Individuals are then sampled at various time intervals and their extremities (e.g., legs) are excised and assayed for virus to determine if ingested virus disseminated from the gut into the hemocoel. Vectors are fed using in vitro methods (e.g., membrane feeder) or by allowing them to feed on anesthetized or restrained vertebrates purposefully infected with the virus in question. Almost always, the vertebrates used are “clean,” laboratory-raised species (e.g., rodents, poultry). However, neither method accounts for the fact that the actual vertebrate reservoirs involved in arboviral transmission cycles are often infected with other blood-borne parasites. Particularly important are the Þlarioid nematodes.

A NEW SPECIES OF CREPIDOSTOMUM (DIGENEA: ALLOCREADIIDAE) FROM HIODON TERGISUS IN MISSISSIPPI AND MOLECULAR COMPARISON WITH THREE CONGENERS Vasyl V. Tkach*, Stephen S. Curran†, Jeffrey A. Bell, and Robin M. Overstreet† University of North Dakota, Department of Biology, Starcher Hall Box 9019, 10 Cornell St., Grand Forks, North Dakota 58202. Correspondence should be sent to: vasyl.tkach@email.und.edu ABSTRACT: A new species, Crepidostomum affine n. sp., is described from Hiodon tergisus in Mississippi, and morphological data are provided for Crepidostomum auritum from Aplodinotus grunniens in Mississippi and for Crepidostomum illinoiense from Hiodon alosoides in Minnesota. The new species is most similar morphologically to C. illinoiense, but has a shorter intertesticular space, measuring 0–74 lm (mean ¼ 19.3 6 23.1 SD in 73 specimens) compared with 0–229 lm (mean ¼ 57.3 6 56.7 SD in 34 specimens), and the distance between the ovary and the anterior testis is relatively shorter in the new species, representing 2.6–7.9% of overall body length compared with 4.1–12.4% in C. illinoiense. Fragments of nuclear ribosomal as well as mitochondrial DNA are compared among C. affine n. sp., C. illinoiense, C. auritum and Crepidostomum cornutum. Crepidostomum affine n. sp. and C. illinoiense are most similar, having between 19 and 20 variable bases (1.29–1.36%) in the amplified nuclear ribosomal RNA fragment comprising the complete ITS2 spacer and partial 28S gene, and between 35 and 39 variable bases (8.62–9.61%) in the amplified fragment of the COI region.

Specimens of C. illinoiense from the Missouri River in North Dakota and Red Lake River in Minnesota differed by 1 base (0.07%) in the rRNA fragment and 4 bases (0.95%) in COI fragment. Crepidostomum cornutum and C. auritum also have 19 (1.29%) variable bases in the amplified ITS2 and partial 28S regions and 50 (12.32%) variable bases in the amplified COI region. Both C. cornutum and C. auritum demonstrated much greater levels of differences compared to C. affine n. sp. These results add to previously published data reporting species of fish digeneans that might be endemic to the Pearl and Pascagoula river basins in Mississippi.

During parasite surveys of rivers in North America, we found that 2 populations of digeneans consistent with the diagnosis and description for Crepidostomum illinoiense Faust, 1918, were clearly genetically distinct. Examination of whole-mounted specimens revealed slight morphological differences between the 2 populations. One of these populations (from the Upper Mississippi River Basin) corresponded to C. illinoiense, while the other (from the Pearl and Pascagoula River Basins in Mississippi) is described as a new species. Herein, we provide a morphological description of this new species from Hiodon tergisus in the Pearl River and morphological data for C. illinoiense. Additionally, 2 other species belonging in Crepidostomum Braun, 1900, were found in the Pearl and Pascagoula Rivers: Crepidostomum auritum (MacCallum, 1919) Hopkins, 1934, from the Pearl River, and Crepidostomum cornutum (Osborn, 1903) Stafford, 1904, from the Pascagoula River. Hopkins (1934) stated that C. auritum was likely a synonym of C. cornutum, but Caira (1989) demonstrated that C. auritum was a distinct species based on morphological comparison. Our data support Caira’s (1989) opinion. Morphological data are provided for C. auritum because of the paucity of reports of that species. Sequences of nuclear large ribosomal subunit DNA (28S) gene and mitochondrial cytochrome oxidase I gene are compared among C. illinoiense, the new species, C. auritum, and C. cornutum.

MATERIALS AND METHODS Digeneans resembling C. illinoiense and considered herein to represent a new species were collected from Hiodon tergisus Lesueur, 1818, electrofished from the Pearl River, Pearl River County, Mississippi on 21 October 2004 (n ¼ 2) and 11 May 2005 (n ¼ 1) and from the Pascagoula River Basin, Green County, Mississippi, on 4 October 2011 (n ¼ 1).

Minnesota, on 27 June 2005 (n ¼ 4) and from Missouri River (Lake Sakakawea) on 19 June 2007 (n ¼ 2). Specimens of C. auritum were collected from Aplodinotus grunniens Rafinesque, 1819 (n ¼ 1) electrofished from the Pearl River, Hancock County, Mississippi, on 27 May 2005. Specimens of C. cornutum were collected from Lepomis gulosus (Cuvier, 1829) (n ¼ 2) from the Pascagoula River, George County, Mississippi, on 10 April 2003. Digeneans were removed from the intestine of the hosts, rinsed in 0.85% saline solution, and either placed in 95% ethanol and stored cold or killed with near boiling hot tap water. Those killed in tap water were immediately placed in 10% neutral phosphate buffered formalin solution or 70% ethanol and stored. Whole mounts were made from digeneans stored in formalin solution or 70% ethanol following the procedure in Curran et al. (2006). Some terms used to describe morphological features are from Manter (1970). Drawings were made with the aid of a drawing tube. Measurements are given as ranges in micrometers (lm) in the descriptions. Museum specimens were examined at the United States National Parasite Collection, Beltsville, Maryland (USNPC), and at the Harold W. Manter Laboratory of Parasitology, University of Nebraska, Lincoln, Nebraska (HWML) (Table I). Genomic DNA was extracted from individual ethanol fixed specimens following the protocol of Tkach and Pawlowski (1999). The approximately 2,500 bp long nuclear ribosomal fragment encompassing 3 0 end of the 18S nuclear rRNA gene, ITS region (ITS1þ5.8SþITS2), and 5 0 end of the 28S rRNA gene (including variable domains D1-D3) was targeted for amplification

by PCR from 4 individual specimens of the new species, 9 specimens of C. illinoiense, 2 specimens of C. auritum, and 2 specimens of C. cornutum.

Approximately 410 base pair fragment of cytochrome oxidase subunit I gene (COI) was targeted for amplification by PCR from 3 individual specimens of the new species, 7 specimens of C. illinoiense, 1 specimen of C. auritum, and 1 specimen of C. cornutum. All were amplified on an Eppendorf Master Gradient thermal cycler. The PCR reactions were performed according to protocols described in Tkach et al. (2003).

Products were purified using Qiagen Qiaquicke columns (Qiagen, Germantown, Maryland), sequenced using ABI BigDyee chemistry, alcohol-precipitated, and run on an ABI Prism 3,100e automated capillary sequencer (Life Technologies, Grand Island, New York). For the rRNA fragment, sequencing and PCR primers are listed in Curran et al. (2006, 2013) while for the COI fragment the forward primer JB3 (5 0 TTTTTTGGGCATCCTGAGGTTTAT-3 0 ) published by Hu et al. (2002) and reverse primer JB5 (5 0 -AGCACCTAAACTTAAAACATAAT GAAAATG-3 0 ) published by Derycke et al. (2005) were used for both PCR and sequencing reactions. Contiguous sequences were assembled and edited using Sequenchere software (GeneCodes Corp., ver. 4.1.4; Ann Arbor, Michigan). Sequences were aligned and compared using BioEdit software, version 7.0.1 (Hall, 1999). The sequences used in the comparative pairwise analysis are deposited in GenBank (Table II), and associated vouchers are deposited in the USNPC and HWML (Table I).

Since most of the ITS1 region of the new species could not be sequenced

Abstract Avian host life history traits have been hypothesized to predict rates of infection by haemosporidian parasites. Using molecular techniques, we tested this hypothesis for parasites from three haemosporidian genera (Plasmodium, Haemoproteus, and Leucocytozoon) collected from a diverse sampling of birds in northern Malawi. We found that host life history traits were significantly associated with parasitism rates by all three parasite genera. Nest type and nest location predicted infection probability for all three parasite genera, whereas flocking behavior is an important predictor of Plasmodium and Haemoproteus infection and habitat is an important predictor of Leucocytozoon infection. Parasite prevalence was 79.1% across all individuals sampled, higher than that reported for comparable studies from any other region of the world. Parasite diversity was also exceptionally high, with 248 parasite cytochrome b lineages identified from 152 host species. A large proportion of Plasmodium, Haemoproteus, and Leucocytozoon parasite DNA sequences identified in this study represent new, previously undocumented lineages (n = 201; 81% of total identified) based on BLAST queries against the avian malaria database, MalAvi.

Introduction Vector-borne pathogens are responsible for a vast number of diseases that negatively impact animal and human health. Many of these pathogens can infect multiple hosts, and prevalence varies among susceptible host species [1, 2]. Although factors contributing to variation in host

A new real-time PCR protocol for detection of avian haemosporidians Jeffrey A. Bell1*, Jason D. Weckstein2, Alan Fecchio2 and Vasyl V. Tkach1 Abstract Background: Birds possess the most diverse assemblage of haemosporidian parasites; including three genera, Plasmodium, Haemoproteus, and Leucocytozoon. Currently there are over 200 morphologically identified avian haemosporidian species, although true species richness is unknown due to great genetic diversity and insufficient sampling in highly diverse regions. Studies aimed at surveying haemosporidian diversity involve collecting and screening samples from hundreds to thousands of individuals. Currently, screening relies on microscopy and/or single or nested standard PCR. Although effective, these methods are time and resource consuming, and in the case of microscopy require substantial expertise. Here we report a newly developed real-time PCR protocol designed to quickly and reliably detect all three genera of avian haemosporidians in a single biochemical reaction.

Methods: Using available DNA sequences from avian haemosporidians we designed primers R330F and R480RL, which flank a 182 base pair fragment of mitochondrial conserved rDNA. These primers were initially tested using real-time PCR on samples from Malawi, Africa, previously screened for avian haemosporidians using traditional nested PCR. Our real time protocol was further tested on 94 samples from the Cerrado biome of Brazil, previously screened using a single PCR assay for haemosporidian parasites. These samples were also amplified using modified nested PCR protocols, allowing for comparisons between the three different screening methods (single PCR, nested PCR, real-time PCR).

Results: The real-time PCR protocol successfully identified all three genera of avian haemosporidians from both single and mixed infections previously detected from Malawi. There was no significant difference between the three different screening protocols used for the 94 samples from the Brazilian Cerrado (Ď&#x2021;2 = 0.3429, df = 2, P = 0.842).

After proving effective, the real-time protocol was used to screen 2113 Brazilian samples, identifying 693 positive samples.

Conclusions: Our real-time PCR assay proved as effective as two widely used molecular screening techniques, single PCR and nested PCR. However, the real-time protocol has the distinct advantage of detecting all three genera in a single reaction, which significantly increases efficiency by greatly decreasing screening time and cost.

Our real-time PCR protocol is therefore a valuable tool in the quickly expanding field of avian haemosporidian research.

Plumage coloration deriving from carotenoid and melanin pigments can be a quality signal in birds, and can be under conspecific inspection in social interactions.

For example, parasite load and immune system status can be inferred through plumage color intensity, and can influence the choice of sexual partners. Here, we evaluated two plumage ornaments in the Yellow-billed Cardinal [Paroaria capitata (d’Orbigny & Lafresnaye 1837)]: the carotenoid-based coloration of the cap and the melanin-based coloration of the bib. We evaluated whether these ornaments were related to blood parasite burden, immunological status and body condition, and whether they could reveal individual sex and age. Cardinals were mist-netted in a Brazilian wetland, and 12 individuals were infected with malaria parasites. Both carotenoid and melanin colorations were related to age, but only carotenoids reflected immunological status. Adult cardinals presented redder caps and darker bibs in comparison to juveniles, and redder caps were associated with low values of heterophil to lymphocyte ratio (H/L, indicating lower stress level). Plumage coloration did not indicate individual sex or parasite infection. Taken together, these results demonstrated that both melanin- and carotenoid-based coloration in cardinals can potentially reflect significant information for social interactions, such as individual age and experience, but apparently only carotenoid coloration is condition-dependent and could reliably indicate quality.

(Received 15 November 2016; revised 19 January 2017; accepted 24 January 2017) SUMMARY

Parasites of the genera Plasmodium and Haemoproteus (Apicomplexa: Haemosporida) are a diverse group of pathogens that infect birds nearly worldwide. Despite their ubiquity, the ecological and evolutionary factors that shape the diversity and distribution of these protozoan parasites among avian communities and geographic regions are poorly understood. Based on a survey throughout the Neotropics of the haemosporidian parasites infecting manakins (Pipridae), a family of Passerine birds endemic to this region, we asked whether host relatedness, ecological similarity and geographic proximity structure parasite turnover between manakin species and local manakin assemblages. We used molecular methods to screen 1343 individuals of 30 manakin species for the presence of parasites. We found no significant correlations between manakin parasite lineage turnover and both manakin species turnover and geographic distance. Climate differences, species turnover in the larger bird community and parasite lineage turnover in non-manakin hosts did not correlate with manakin parasite lineage turnover. We also found no evidence that manakin parasite lineage turnover among host species correlates with range overlap and genetic divergence among hosts. Our analyses indicate that host switching (turnover among host species) and dispersal (turnover among locations) of haemosporidian parasites in manakins are not constrained at this scale.

lineages, which depend on several attributes of hosts (Poulin, 1997). For example, the geographic range of the host has been shown to positively influence parasite richness: host species with larger ranges would presumably be exposed to, and colonized by, more parasite species over evolutionary time (Poulin, 1997, 2007). Indeed, this pattern has been found among several types of parasites and

(Received 7 November 2016; revised 16 February 2017; accepted 17 February 2017) SUMMARY

Avian malaria is a vector transmitted disease caused by Plasmodium and recent studies suggest that variation in its prevalence across avian hosts is correlated with a variety of ecological traits. Here we examine the relationship between prevalence and diversity of Plasmodium lineages in southeastern Amazonia and: (1) host ecological traits (nest location, nest type, flocking behaviour and diet); (2) density and diversity of avian hosts; (3) abundance and diversity of mosquitoes; and (4) season. We used molecular methods to detect Plasmodium in blood samples from 675 individual birds of 120 species. Based on cytochrome b sequences, we recovered 89 lineages of Plasmodium from 136 infected individuals sampled across seven localities. Plasmodium prevalence was homogeneous over time (dry season and flooding season) and space, but heterogeneous among 51 avian host species. Variation in prevalence among bird species was not explained by avian ecological traits, density of avian hosts, or mosquito abundance. However, Plasmodium lineage diversity was positively correlated with mosquito abundance. Interestingly, our results suggest that avian host traits are less important determinants of Plasmodium prevalence and diversity in southeastern Amazonia than in other regions in which they have been investigated.

INTRODUCTION

Many factors have been proposed to explain parasite diversity (Poulin, 1997). For example, previous studies have shown that species richness increases towards the equator for some groups of parasitic organisms (Rohde and Heap, 1998; Guernier et al.

2004; Nunn et al. 2005). However, a recent meta-analysis of 62 studies involving animal, plant and fungal hosts showed that there was no strong evidence for an effect of latitude on parasite species richness (Kamiya et al. 2014). Parasite diversity might be determined by characteristics of hosts rather than those of the environment. For example, host body size, population density and geographic range have all been suggested as universal predictors of variation in parasite species richness (Kamiya et al. 2014). Nevertheless, the meta-analysis of Kamiya et al. (2014) did not include vector-transmitted parasites.

can be especially important for parasites, which depend on hematophagous insects for reproduction because the concentration of hosts in a given area potentially affects the prevalence and transmission of vector-borne pathogens by influencing encounter rates between vectors and susceptible hosts (Nunn and Heymann, 2005).

Avian malaria is a worldwide, vector-transmitted disease caused by haemosporidian parasites in the genus Plasmodium (Valkiūnas, 2005). These parasites reproduce sexually in female mosquito vectors from the genera Culex, Aedes, Culiseta, Anopheles, Mansonia, Aedeomyia and Coquillettidia (Diptera: Culicidae) (Valkiūnas, 2005; Njabo et al. 2009; Santiago-Alarcon et al. 2012). Environmental factors, especially temperature, can play a role in the distribution, prevalence and transmission of these parasites (Gonzalez-Quevedo et al. 2014; Oakgrove et al.

2014). Temperature constrains not only parasite sporogonic development (LaPointe et al. 2010), but also influences the activity and development of the mosquito vectors, which are important determinants of the prevalence and transmission of avian malaria.

Identifying the mechanisms driving the distribution and diversity of parasitic organisms and characterizing the structure of parasite assemblages are critical to understanding host–parasite evolution, community dynamics, and disease transmission risk. Haemosporidian parasites of the genera Plasmodium and Haemoproteus are a diverse and cosmopolitan group of bird pathogens. Despite their global distribution, the ecological and historical factors shaping the diversity and distribution of these protozoan parasites across avian communities and geographic regions remain unclear. Here we used a region of the mitochondrial cytochrome b gene to characterize the diversity, biogeographical patterns, and phylogenetic relationships of Plasmodium and Haemoproteus infecting Amazonian birds. Specifically, we asked whether, and how, host community similarity and geography (latitude and area of endemism) structure parasite assemblages across 15 avian communities in the Amazon Basin. We identified 265 lineages of haemosporidians recovered from 2661 sampled birds from 330 species.

Infection prevalence varied widely among host species, avian communities, areas of endemism, and latitude. Composition analysis demonstrated that both malarial parasites and host communities differed across areas of endemism and as a function of latitude. Thus, areas with similar avian community composition were similar in their parasite communities. Our analyses, within a regional biogeographic context, imply that host switching is the main event promoting diversification in malarial parasites. Although dispersal of haemosporidian parasites was constrained across six areas of endemism, these pathogens are not dispersal-limited among communities within the same area of endemism. Our findings indicate that the distribution of malarial parasites in Amazonian birds is largely dependent on local ecological conditions and host evolutionary relationships.

Parasites and pathogens can play an important role in structuring biological communities and maintaining biodiversity (Daszak et al. 2000, Ricklefs 2010). For instance, parasites can influence interactions among competitors and predators (Hatcher et al. 2006), impact the host extinction dynamics (McCallum and Dobson 1995), affect ecosystem functioning and productivity (Hudson et al. 2006), and the success of introduced host species in their non-native range (Torchin et al. 2003). However, the processes structuring these often-hidden communities of parasites and pathogens remain poorly understood, especially when the parasite community is highly diverse and its taxonomic composition is not well established. Therefore, characterizing the structure of parasite associations is the first step in understanding

host–parasite evolution, community dynamics, and disease transmission risk.

Ecological factors may shape parasite assemblage structure because of their potential influence on colonization and extinction of these organisms (Poulin 1997, 2007, Clayton et al. 2016). For example, for free-living organisms, similarity in species composition among communities decreases with increasing geographic distance (Nekola and White 1999), and this ecological pattern has also been demonstrated for parasites (Poulin 2003). This increasing dissimilarity in parasite assemblages with increased geographic distance could be caused by two mechanisms: 1) a decrease in environmental similarity with distance (e.g. gradients in temperature and precipitation, turnover of host species, genetic differences Early View (EV): 1-EV
