To understand how life has evolved on Earth, scientists have looked to ecology to see how present-day organisms live with one another and to study the impact they and their environment have on each other.

On this page, you'll find information about ecology as a discipline, what University of Alberta ecologists are researching, and the effect their work has.

Ecology is an area of biology that studies the interactions of organisms with one another and their environment.

Ecology is a broad field that investigates many topic areas. A degree in Ecology can take students on many career paths, including bioinformatics, environmental law, pest and disease management, wildlife conservation, and more.
