Associate Professor


Dr. Zachary Darnell’s research focuses on plastic and adaptive behavioral responses to environmental stressors, in the context of the physiology and life history of the organism. Behavior represents the most rapid and flexible response available to an organism challenged by an environmental stressor. We are interested in (1) the fitness consequences of behavioral flexibility, (2) the trade-offs associated with behavioral decisions and the modulation of trade-offs by abiotic and biotic factors, and (2) the physiological drivers of behavior. Our work also has a strong applied focus, using behavioral and physiological ecology to address questions related to conservation and management of marine species.
