For nonmajors. Selected current topics in biology, used to illustrate the strengths and limitations, of the process of science and the approaches, biologists use to learn about living organisms., Emphasis changes from semester to semester,, reflecting the expertise and interests of the, faculty member teaching the course. For further, information, consult the appropriate faculty, member before registration. Lecture and, laboratory. May not be applied toward the biology, major.
An introduction to principles underlying the, distribution and abundance of species., Examination of how these principles can inform, understanding of issues like overpopulation,, climate change, invasive species, pollution,, species extinction. Introduction to the methods, of scientific investigation through laboratory, and field studies that describe ecological, phenomena and test hypotheses. Lecture and, laboratory. Note: This course is part of the, Department of Biology's core curriculum and is, intended for biology majors, potential biology, majors, and environmental studies majors. The, curriculum is challenging and requires a, significant time commitment. Therefore, nonmajors, are encouraged to fulfill their general education, requirements by enrolling in one of the, perspectives courses in the natural sciences.

Key concepts of plant biology, including, morphology, physiology, adaptations to life on, land, and ecological interactions with other organisms. Emphasis on the roles of plants in ecosystems and human lives. Key characteristics of major plant lineages in the context of how plants have become such a diverse and successful group of organisms. Students conduct independent research, projects on various aspects of plant biology. Laboratory.
The ecology and evolution of disease in human, plants, and animal systems. Topics will include, causes of disease emergence; host-pathogen, interactions and co-evolution; interactions, between disease and community diversity; and, anthropogenic effects on disease, among others., We will use case studies, mathematical theory,, and examples from the primary literature to, understand the causes and consequences of, host-pathogen interactions for populations,, communities, and ecosystems. Intended for, biology, biochemistry and molecular biology, and, environmental studies majors.
Study of the mechanisms responsible for evolutionary change and of their results. History of evolutionary thought, evolution of single-gene and quantitative genetic traits, speciation, and molecular evolution. Role of evolutionary ideas in issues such as species conservation, medicine, science-religion conflicts. Lecture only.
Selected topics in biology. Students will have the, opportunity to hear research seminars from outside, scientists. Students enrolled in the course will, develop and present a research seminar of their, own. All students taking this course for credit, will be required to attend all seminar, presentations, both by outside speakers and by, their peers, and to participate in the, question-and-answer session after the seminar.
Advanced study of theory and methods of, reconstructing hypotheses of evolutionary history., Modern phylogenetics relies heavily on models of, molecular evolution, thus the course includes a, foundation of molecular evolutionary theory. We, discuss applications of phylogenies including, analyses of gene family evolution, the emergence, of infectious disease, biogeography, and, coevolution. The lab centers on computational, analyses.
The biology of the nervous systems of vertebrates, and invertebrates, with emphasis on cellular and, molecular approaches. Electrical signaling in, excitable cells, the physiology and biochemistry, of synaptic transmission, neuropharmacology. The, biological bases of learning, memory, and some, neurological disorders. Sensory systems and, neuronal development. Laboratory focus on, student-designed projects. Lecture and laboratory.

This short exam for graduating biology majors will help the department assess the effectiveness of our current curriculum.
