Gabe Barrile

Gabe graduated from Bloomsburg University, PA in 2013, majoring in Biology. His undergraduate research focused on life-history trait evolution in Fowler’s toads (Anaxyrus fowleri ) on several Atlantic Coast barrier islands. Additionally, Gabe compared time-budgeting behavior between captive and free-ranging black-handed spider monkeys (Ateles geoffroyi ) on the Osa Peninsula of Costa Rica. After graduation, he taught coastal and marine ecology at the Chincoteague Bay Field Station near Wallops Island, VA.

Gabe recently earned a Ph.D. in Ecology (May 2021) from the University of Wyoming, where he was hosted by the Department of Zoology and Physiology and the Wyoming Cooperative Fish and Wildlife Research Unit. His doctoral research investigated the behavioral and demographic responses of amphibian populations to infectious disease and various forms of environmental change. Gabe currently works as a Postdoctoral Research Associate in Quantitative Ecology at the Colorado Natural Heritage Program, Colorado State University. His research seeks to better understand the boom-and-bust cycles of black-tailed prairie dogs in the context of climate and sylvatic plague, as well as the implications of those dynamics for livestock production and wildlife conservation in grassland ecosystems. Gabe plans to remain at the interface of basic and applied science by conducting research that both advances ecological theory and helps to develop practical solutions to conservation challenges.
