Biogeography of human impacts

Threats to marine ecosystems from human activities are diverse and widespread, affecting nearly all ecosystems globally to varying degrees. Likewise, conservation measures to mitigate negative human impacts are growing in number and scope. Our research in this area uses biogeographic comparisons to shed light on how different types of marine ecosystems respond to both different types and levels of human impacts, primarily fishing, as well as the conservation measures designed to protect ecosystems.

Projects in progress

We have large, ongoing NSF-funded collaboration with colleagues from the Australian Institute of Marine Science and the University of Tasmania examining if and how the cascading, indirect effects of fishing (i.e., trophic cascades) vary over latitude. Stay tuned!
