Cade Coldren, Ph.D.

Professional Summary

My research interests are varied, but tend to be centered around conservation issues, whether it is avian conservation, urban wildlife, or water resources. My current research focus is on avian and urban wildlife, primarily looking at invasive species impacts, as well as evaluating long-term population impacts from factors such as climate change. I am also interested in irruptive avian species, and how irruption dynamics are being influenced by climate change impacts. Much of my work in the last two decades has centered on the use of the Ecological Dynamics Simulation (EDYS) model, which is a general ecosystem model that has been applied to numerous ecosystem types, from marshes to grasslands to savannah to forests to tundra. EDYS has been used primarily to evaluate anthropogenic impacts on ecosystem components, including water, plants, sediment movement, animal diets, and endangered species.
