Abstract

In complex systems, such as coral reefs, determining the strength of predator-prey interactions as a structuring ecological force is challenging because interactions between multiple predators unfold in patchy seascapes. In this thesis, I used small- and large-scale studies to examine the capacity for reef sharks to alter the amount of time mesopredatory fishes spend foraging and their use of the water column. I demonstrated that these interactions are context-dependent- influenced by the characteristics of both sharks and other mesopredators in addition to the environment in which they interact . Finally, I discuss the significance of these interactions within coral reefs.
