More than a Paycheck Lab Technician Positions Enhance Learning Experience for Two Biology Undergraduate Students

T

eall Culbertson and Graciela Orozco admit they took their jobs as undergraduate research technicians at Kansas State University for the paycheck, but they know now the handson experiences they’ve gained will pay off more in the future.   C u l b e r t s o n , Teall Culbertson in the lab senior in biology, Arkansas City, and Graciela Orozco, junior in animal sciences and industry and biology, Kanopolis, both work for Jesse Nippert, assistant professor of biology, in his research lab on campus.  “I didn’t know what to expect in terms of student workers when I started my lab at K-State,” Nippert said. “I had no idea just how much enthusiasm undergraduates would have for research, but they are critical to everything I do in the lab.”  While the paycheck first drew Culbertson and Orozco to Nippert’s lab, both have

developed a strong interest in conducting their own research in addition to assisting with Nippert’s research.  “Jesse suggested that doing some research would be good for me,” Culbertson said. “I wanted to do research that’s applicable and meant something; I wanted it to have an influence.”  Culbertson is investigating where bison drink the majority of their water on Konza Prairie Biological Station by measuring stable isotopes levels in fecal samples. Stable isotopes are variations of chemical elements, such as oxygen, carbon and hydrogen, and contain additional neutrons in their atomic nuclei, often used as biological tracers.  By measuring changes in the stable isotopic signature of the fecal samples, Culbertson can compare them to the levels

of the stable isotopes found in local water sources, identifying where the bison are drinking.  Nippert believes that Culbertson’s research experience with bison will be as valuable to her future career as anything she has learned through traditional classroom education. She has earned early admission to K-State’s College of Veterinary Medicine and wants to study large animal medicine.  “Performing my own research project with guidance from a real scientist like Jesse is a unique experience; plus there’s the Graciela Orozco in the lab possibility that I could get a paper published before I’m even out of college,” Culbertson said.  Culbertson and Orozco have found that working in the lab increases their understanding of the scientific process, aiding retention of concepts discussed in their classes. . . .

  he Black-footed Ferret, Mustela nigripes, one of the rarest and most specialized predators in North America is now “roaming the range” in Kansas, thanks to a coalition of private landowners and wildlife researchers.  One would think that this would be cause for celebration, particularly since the predator feeds on prairie dogs, a species widely considered to be a pest. However, as I learned when I participated in a recent release of ferrets on a ranch in Logan County, lots of folks are upset by this for many reasons.  The species lives solely in prairie dog colonies, and depends on the existence of prairie dogs for both food and shelter, since it lives in prairie dog burrows.  As the settlement of the western plains began, prairie dogs,

despised as pests because they competed with cattle for food, became less common. Many western states, including Kansas, have laws allowing ranchers to exterminate the prairie dogs by shooting or poisoning them, even allowing local county governments to poison them on private land, without consent from land owners. Prairie dog populations dwindled (currently less than 1% of the numbers at the time of Lewis and Clark), and with them, the ferret population declined even more quickly. Ferrets were thought to be extinct by 1974.  But in 1981 a Wyoming farm dog found a ferret and brought it home. A search for the source population found about 130 ferrets in a nearby prairie dog town. Work began to protect and expand this population (KSU Biologist Samantha Wisely has contributed to that effort), and now includes captive breeding efforts at five different locations in the USA and Canada. Ferrets born and raised in captivity have been released at multiple sites,

Biology Instructor Turns Class into Positive Hands-on Learning for Variety of Students

Pat Silovsky presents Lurch, a turkey vulture, to students in Physiological Adaptations of Animals.

T

he Physiological Adaptations of Animals course recently received a face lift by one of the Division of Biology’s younger instructors, Ashley Rhodes. Two years ago, Rhodes made some major transformations for the course and since that time she has excelled as the instructor and created an atmosphere that is tailored to a variety of learning styles.  “We handed her the responsibility for a course which has traditionally been challenging for both students and instructors. She reorganized both the lecture and lab portions of the course, developed new assignments and field trips, and solicited input from the other faculty members whose students were in the curriculum where this is a required course. In other words, just as she has done in the other courses which she teaches, Ashley handled this assignment professionally and intelligently,” said Dave Rintoul, Interim Director of the Division of Biology.  Rhodes’s teaching philosophies are simple. She strives to be flexible, dynamic, transparent, and construct lessons on a shared level of knowledge in the classroom.  “I don’t really go in with a set list of what I want to accomplish in every class, because the mood of the students or yourself can dictate how

However, she continues to attribute a great deal of her success to lessons learned throughout her friendship with Consigli.  “Dr. Consigli had an intense and infectious love for creating new knowledge, and the smile he would express when he pondered the outcome of an experiment was priceless,” Trempy said. “He taught me to be compassionate and patient with students, and thoughtful to colleagues. He also demonstrated to me that life was about providing opportunities for others.”

 In an effort to provide students with the same kind of influence Trempy experienced at K-State, she values her work as an associate dean on a personal level. Her focus on student engagement issues, developing instructional opportunities that gauge student learning, and ways to increase student opportunities for success is not just an administrative agenda to increase retention or graduation rates but rather because she genuinely cares, she said. She has modeled her actions after what she witnessed from Consigli and other professors at K-State.  “I fondly remember the biology professors at K-State, and the engaging learning communities they built in their research programs for students such as myself,” Trempy said. “This is an aspect that I emulate in my career.

  n the search for a cure to pathogens carried by mosquitoes, Kristin Michel, assistant professor, Rollie Clem, associate professor, and recent Ph.D graduate, Bart Bryant, were coauthors of “Pathogenomics of Culex quinquefasciatus (southern house mosquito) and MetaAnalysis of Infection Response to Diverse Pathogens,” published in the October 1 issue of Science.  This article is a companion paper to the publication of the full genome sequence of the southern house mosquito, available in the same issue of Science. Michel, also a coauthor on this paper, contributed to the annotation of the genome. The third mosquito species to have its genome sequenced, C. quinquefasciatus, is a major vector for a variety of diseases, such as West Nile virus, common in the United States.  Nearly 10 years in the making, the overall goal of this project was to understand how this mosquito responds genetically to infection by viruses or other pathogens. The researchers compared their research results on the southern house mosquito with 25 other research projects on vector-pathogen interactions in mosquitoes, which revealed common responses to a variety of different pathogens across three different species of mosquitoes.  “Ultimately, this may give clues on how to prevent infection or how to stop the spread of these pathogens by mosquitoes,” Michel said.


Understanding the Basics of How Our World Works

W

  hile some biological research may not directly provide cures for major diseases, it can provide the scientific basis for research that might.  Work by Division of Biology’s Jeroen Roelofs, assistant professor, is one such example.  Roelofs studies a cellular structure called the proteasome, a large complex that degrades damaged or misfolded proteins, critical for normal cellular functions.  The 26S proteasome has been shown to control various essential biochemical processes, including DNA synthesis and repair, transcription, translation and cell signal transduction. Several human diseases can be traced to its malfunction, Roelofs said.  “We’re interested in that complex because it is the garbage machine of the cell. For the cell to perform well it needs to get

rid of proteins that are either not needed anymore or damaged because they could become toxic,” he said.  Roelofs was invited to write a research review about his work, which was published in the July issue of Trends in Cell Biology. The article, “Assembly, Structure, and Function of the 26S Proteasome,” is his first publication as a principal investigator since he joined the faculty in Nov. 2009. The research was supported by a $40,000 grant from K-INBRE.  Roelofs said he is not necessarily looking to find the cure for disease; instead he is trying to uncover details of normal cellular functions. His investigation is the type that often creates unexpected pathways for further scientific discoveries, techniques or cures for diseases.  “I’m not trying to fix something that’s broken; I’m just trying to understand how it works,” he said. “It could be that it doesn’t directly

translate into a drug, but even then the added knowledge is still very valuable and could lead directly or indirectly to something else.”  Roelofs was recently awarded a three-year grant from NIH, Centers of Biomedical Research Excellence.

The program gives her the opportunity and funding to continue with her current research project or to develop a new project in an area of her choice. The McNair program also supports her in preparing for the Graduate Record Examination and applying to graduate schools.  “I think it’s been a good experience to see everything that goes into research, and I think it’s been a motivating factor for both of them to continue on to professional school,” Nippert said.  Working in the lab together has given both Culbertson and Orozco more than just an educational

experience; the two have developed a close friendship.  “Since we had to work closely together in the lab, we found out that even though Teall and I may be similar people in some ways, we’re also different, but those differences complement each other,” Orozco said. “Teall is not always that outgoing, but I can get her to do things that she wouldn’t normally do. In that sense, I’m kind of a risk taker, and she’s my voice of reason.”  “Their best qualities as research technicians are that they’re really independent and are great at problem solving. I don’t have to check in on them, which is good because I don’t like to micromanage,” Nippert said. “They’re also pretty funny and a fantastic asset to my lab.”
