Evan Adams, Ph.D.

Ecological Modeler

Evan is a quantitative ecologist whose work focuses on how animal populations respond to environmental change throughout complex life cycles.

Evan earned his master's degree in wildlife ecology and conservation from the University of Florida, where he worked under Dr. Peter Frederick to study the developmental and physiological effects of mercury exposure to the White Ibis. For his doctorate with Dr. Brian Olsen at the University of Maine, he developed new methods for estimating the size of migrating populations and applied these models to determine how climate and weather influence population status and behavior.

Now he works as a quantitative ecologist and designs experiments and models to understand how animals respond to a rapidly changing environment. Current projects include modeling offshore migratory events across the Atlantic coast of the United States and developing models that predict how salt marsh species will respond to sea level rise. Evan's research has been conducted in diverse locales including Caribbean lowland Costa Rica, Florida’s Everglades, and Hudson’s Bay, Canada.
