Biology Major (B.S.) Area of Concentration Option

As an alternative to the upper-level requirements for a Biology B.S. degree (see Major Requirements 5-8), students may choose an Area of Concentration (AoC).  AoCs help students develop additional expertise in specific areas of Biology and may require additional coursework.

Integrative and Organismal Biology

Dealing with complex biological systems requires an understanding of interactions at multiple levels of organization. The Integrative and Organismal Biology area of concentration provides a course of study in whole-organism and physiological systems within evolutionary and ecological contexts. With a combination of lecture and lab courses, students can build a degree around plant or animal model systems or focus on biological diversity and interactions among organisms. Through all of these pathways, students gain an understanding of biological processes at the levels of specific physiological systems, organisms, and ecosystems across evolutionary time. Common themes in scientific method and measurement are also emphasized throughout the concentration to build a skill set that can be applied to multiple types of biological endeavor.

Students who graduate with a concentration in Integrative and Organismal Systems are equipped to enter into careers in health-related fields (e.g., human or veterinary medicine), wildlife biology, management, conservation, biological research or education, and other exciting fields focusing on the biology of whole organisms.

In order to complete a Bachelor of Science in Biology with a concentration in Integrative and Organismal Biology, students must complete 18 upper division credits in Biology or Biology-approved classes in addition to all other degree requirements (Gen Ed, CASE, Biology core, etc.).

The 18 credits are to be fulfilled from the courses below and in the manner described:
