Scott J. Werner, Research Wildlife Biologist |
Dr. Scott J. Werner is a Research Wildlife Biologist at the National Wildlife Research Center (NWRC) in Fort Collins, Colorado. He earned a Ph.D. in Range Science (Animal Behavior) at Utah State University where he studied the behavior and thermal ecology of pocket gophers associated with impacts to forest production in the U.S. Pacific Northwest. After a postdoctoral appointment with USDA’s Agricultural Research Service, Dr. Werner served as the Project Leader at NWRC’s Field Station in Starkville, Mississippi. While there he researched bird-aquaculture conflicts. He has been at the Fort Collins headquarters of NWRC since 2002.
Dr. Werner’s research interests include the physiological bases of food and habitat selection, and the development of non-lethal repellents for wildlife damage management.
