and other expenses. Prerequisites: 201 and departmental permission. Three lecture hours and four laboratory hours. Four semester hours. BIOL 350 Special Topics in Biology Selected topics in biology chosen by the instructor in response to student needs and interests. Prerequisites: 117 and permission of instructor. BIOL 360 Population and Conservation Biology Exploration of factors which affect short-term and long-term stability and health of biological populations, including immigration, emigration, recruitment and mortality, and the environmental factors which can affect each of these forces. Emphasis on understanding and manipulating mathematical models of hypothetical populations. Conservation of biological populations and communities, as well as critical natural resources. Prerequisites: 117 and 201. Four semester hours. BIOL 411 Ecology Study of spatial and temporal dynamics of interactions between species and their environment, with emphasis on the use of both mathematical and descriptive models to understand ecological processes at the species, community, and ecosystem levels. Examination of the role of genetics, physiology, reproduction, and dispersal in shaping organism ecology. Extensive laboratory component including the use of experimental and natural populations for student projects. Prerequisites: Biology 201 and Mathematics 151, or departmental permission. Three lecture hours and four laboratory hours. Four semester hours. BIOL 415 Biogeography Patterns and dynamics of the geographic distribution and abundance of plants and animals. Historical, ecological, and evolutional foundations of biogeography. Applications of biogeographical models in the assessment of habitat degradation and climate change effects on species distribution and abundance. Prerequisites: 117 and 201, or permission of instructor. Three lecture hours and four laboratory hours. Four semester hours. BIOL 420 Evolutionary Biology Patterns and processes of organismal change over time, emphasizing both micro- and macroevolution. Development of evolutionary thought, natural selection, speciation, phylogenetics, and the origin of life. Prerequisite: C or better in 300, or permission of instructor. BIOL 425 General Physiology Chemical and physical functions of organisms including maintenance of homeostasis, water balance, metabolism, movement, gas exchange, and hormonal regulation, with emphasis on human systems and comparisons to other animals and to plants. Analysis of current literature and case studies, use of relevant instrumentation, and interpretation of data. Includes a service learning component. Prerequisites: Chemistry 111 and 112, and C or better in Biology 201. Three lecture hours and three laboratory hours. Four semester hours.
