The biology major at Principia College is ecologically based and exposes students to a variety of field, laboratory, and classroom experiences. Through studies of our 2,600 acre campus, guided travel (regionally and abroad), theoretical work, and internships, biology students gain an understanding of basic plant and animal biology, the dynamics of biological populations and communities, and major ecosystem functions.  Biology students also develop independent field research skills that support future graduate studies and employment in conservation and other fields. The enviornmental studies major includes a science-based interdisciplinary course of study. Students have an opportunity to focus their studies on various aspects of human-environment interaction, and to work toward resolving environmental problems. The foundation of the program is in biology with support classes in natural resources, earth science, chemistry, and other math and science courses.
