Graduate Program in Ecology

The Ecology degree programs at Utah State University are administered by the interdepartmental Ecology Center. The Ecology Center aims to promote research and graduate education in ecology and to provide expert, professional information and advice for decision-makers. The research carried out by the center’s associates covers the full spectrum of ecology. Students earn their degrees in Ecology while maintaining residence in one of the participating home departments (BIOL, ENVS, PSC, WATS, WILD); the Ecology Center itself does not grant degrees. The candidate must select a major professor from their home department, appropriate to their interests.
