Areas of Interest:
Current research focus is to gain an understanding of the factors that
mediate the impact of diverse predator assemblages on herbivore populations
and the occurrence of trophic cascades. Mediating factors include effects
such as the occurrence of intraguild predation, resource partitioning
among predators, and spatial refuge from predation.
