Overview

The biological sciences examine every aspect of living organisms, from the biochemical reactions involved in supporting cellular processes to the interaction of organisms with their environment. Research is an integral part of the study of biological sciences, and students are encouraged to participate in ongoing research directed by departmental faculty. Each option allows research courses to fulfill up to nine credit hours of restricted or free elective credit.

Between the sophomore-junior and junior-senior years, students can elect to participate in the summer field biology, and conservation biology and ecology programs. Field biology courses serve as required courses in the conservation biology and ecology option and can serve as restricted electives for various programs. Students wishing to participate are encouraged to consult with their advisers early during the academic year to reserve places in the classes. Courses in the summer field program are taught in Africa, Australia, the Bahamas, Costa Rica, Jamaica, Peru and Puerto Rico, and the Appalachian Mountains in the United States.

Minor Program

A minor in biology is offered through the biological sciences department. A complete policy statement regarding minors can be found in the Academic Overview section. Information about current minor offerings is available through the individual colleges/departments.

Research

Biochemistry, Molecular Biology and Molecular Genetics: A variety of molecular and biochemical approaches are used in the department to answer questions related to regulation of cell duplication, signal transduction in early development, circadian rhythms and sensory systems, microbial pathogenesis, plant growth, and the assembly of subcellular structures. A major effort is underway to develop novel cell culture systems for production of synchronously growing populations of human cells. Intracellular complexes of DNA and protein are under study to elucidate the regulatory mechanisms that trigger DNA replication and cell division in bacteria. The role of signal transduction pathways induced by calcium in the fertilization step of embryogenesis is another active area of research. Drug discovery efforts are focused on the genetics of the polyketide synthesis pathway in a variety of uncharacterized microorganisms collected from extreme environments. Development and analysis of new bacterial growth inhibitors is also underway for Mycobacterium, Escherichia and other important bacterial pathogens. Another expanding research area is the neurophysiological and molecular analysis of photoreceptors, particularly the infrared receptors in snakes. The diversity of biochemical and molecular research conducted by members of the biological sciences department provides for a rich and interactive environment for graduate students.

Marine Biology: The marine biology faculty maintain active research programs in finfish, crustacean, molluscan, coral and echinoderm biology. The evolution and ecological physiology of organismal design are investigated using high-speed videography, electromyography, and biomechanical and ecomorphological analysis of feeding in field-caught and laboratory-reared fish. Fisheries research includes analyses of early-life history and recruitment patterns of estuarine-dependent sport fish species. Crustacean research centers on the ecology and physiology of adult and early-life history stages, especially the migratory behavior of spawning female crabs and the recruitment and habitat selection of post larvae. Research on suspension-feeding invertebrates examines the mechanisms responsible for food capture, selection and processing. Remote sensing, as well as laboratory and field investigations of corals, explores the effects of global-climate change on coral reefs. Studies of echinoderms have concentrated on their reproduction, anatomy, systematics and ecology by using physiological, histological, morphological and field techniques. Aquaculture programs are investigating the reproductive and feeding biology of ornamental shellfish and finfish species.

Molecular Marine Biology: Collaborative research among diverse faculty and students enables the application of molecular biological techniques to marine biology topics such as genetic identification of fishery populations, biochemistry of molluscan shell growth, response of marine organisms to anthropogenic pollutants, genetic engineering in aquaculture and the relationship of enzymes to rates of calcification and skeletogenesis in commercially significant marine organisms.

Ecology and Conservation Biology: Research activities include studies of coral reef ecology, climate change, paleobotany, paleoecology, biogeography, biodiversity, macroevolution, freshwater and marine aquaculture, fisheries ecology, population ecology of birds, ecomorphology and the life history and ecology of selected crustaceans and echinoderm species. Study locations range from local to international, including the Indian River Lagoon, Alaska, the Yucatan Peninsula, Panama, the Galapagos Islands, Amazonia and Antarctica.
