Description

I am interested in how animals that occupy basal trophic levels manage the conflicting demands of acquiring resources while avoiding the many hungry mouths in their environment. I study how prey alter their behavior when exposed to elevated predation risk and how these behavioral changes can scale up to affect community and ecosystem-level processes. For my PhD, I studied the role of predatory mysids in limiting the population growth of copepod prey by reducing their mating behavior. In my postdoctoral research, I will determine the effects of anadromous fish migrations on the distribution and behavior of mysid shrimp over diel and seasonal cycles to better understand this critical link in coastal foodwebs.
