Admissions Information

Degree Requirements & Sample 4-Year Program

Program Overview

Biological Sciences provides this program for undergraduate majors who are interested in careers studying marine and freshwater organisms and their environments. Students focusing on terrestrial environments should consider the wildlife and conservation biology track.

Courses meet the requirements for admission to graduate programs in marine biology, zoology, ecology, and conservation biology. The program also provides the necessary background for jobs with state and federal agencies (i.e., USDA or EPA) charged with environmental protection, research and monitoring, and information collection. Tier II social science electives can be chosen to meet the requirements of the Environmental Studies Certificate. For federal job and employment information, see USA Jobs.
