Ecology and Conservation

Ecologists study the interactions and relationships that living organisms have with each other and their environment.  They develop expertise in understanding the composition, distribution, and dynamic processes of the world’s ecosystems and the organisms that live there.  Understanding ecology strongly complements conservation biology, or the study of our planet’s biodiversity for the sake of protecting species, habitats, and ecosystems.  Ecologists and conservationists learn about behavior, biodiversity (from botany to zoology), climate, genetics, evolution, nutrient cycles, natural resources, and more.  Careers in this specialization are often with non-profit environmental groups or governmental agencies aiming to protect and serve the environment and our planet’s biodiversity.

Those planning to work in the field are encouraged to take a course in GPS and GIS, as these tools are often used in field work.  Participating in experiential learning, such as an independent study course, related internship experience, and especially lab/field research is also advised. Many students specializing in this area pursue further education with a Masters or Ph.D.

Suggested Supporting Science Courses

For most students interested in ecology and conservation, taking the minimum course sequences for supporting science requirements (one semester of general chemistry, one semester of organic chemistry, one semester of biochemistry, and one semester of physics) is sufficient. More extensive coursework in chemistry will be useful for ecologists and conservationists wishing to focus on abiotic aspects of the environment. Both introductory statistics and intermediate statistics are recommended; calculus is not typically used in this specialization.

Extracurricular Opportunities

Biological Sciences Club (BSC)

The departmental club for Biology majors and anyone else interested in life science, the Biological Sciences Club features regular faculty speakers on a diverse range of life science topics.
