|Dr. Stewart W. Breck,
Research Wildlife Biologist
Dr. Stewart Breck is a researcher for the USDA-National Wildlife Research Center and his research is focused on carnivore ecology and behavior and minimizing conflict between carnivores and people. Studies include testing nonlethal methods for preventing conflict, measuring the impact of carnivores on livestock, influence of urban environments on carnivore ecology, and population biology and behavioral ecology of carnivores.
