Marine mega-vertebrates and marine food webs
Little is known about the ecological role of marine megavertebrates. Our work on marine food webs seeks to elucidate interactions among different trophic levels including top predators, as well as wildlife-fishery interactions, with the purpose to better inform ecosystem-based management efforts that can be applied by local managers. We engage local communities in the study of ecosystem ecology and the implementation of sustainable fishing practices. For example, to understand the impact of whales on commercial fisheries, we develop food web models to examine the potential impact of a reduction in the abundance of great whales on fishery yield. Our approach has been embraced in discussions about establishing appropriate policies for conserving marine megafauna and sustaining fisheries around the globe.
