Brian Hoover is a seabird ecologist who works on research vessels and island colonies in both the North Atlantic and North Pacific. He completed a PhD at the University of California Davis working on the breeding biology of Leach's storm-petrels in Nova Scotia, and did his postdoctoral research on marine food webs at the Farallon Institute in Petaluma, California. He is now a postdoctoral teaching fellow at Chapman University in southern California.
Brian's talk will discuss how seabirds are excellent tools for monitoring ocean health, as they are often conspicuous and easy to observe, and their survival and reproduction over time reflects conditions in the ocean. Seabirds are visible indicators of conditions and changes in complex marine ecosystems. This talk will review some of the existing literature and background on "seabird as ocean environment indicators", and present results from a recent study that examined global data on seabirds from 46 colonies around the world. Early results suggest that fish-eating, surface foragers in the northern hemisphere are experiencing declines in their breeding productivity relative to seabirds in the southern hemisphere, and this may be associated with the ocean warming at a much faster rate in the northern hemisphere. Planktivores seem to be doing better, but we still need more data. -- Any multi-year data on seabird colonies and numbers would be helpful, so please contact Brian if you have any.
