George Hunt’s research focuses on the ecology and behavior of marine birds and how spatial and temporal variability in marine ecosystems, at a variety of scales, influence marine bird foraging opportunities and reproductive performance. For successful and profitable foraging, many marine birds require concentrations of prey much greater than the overall average. A second facet of his research interests focuses on ecosystem-level investigations of spatial and temporal variability in the Bering Sea and Aleutian Islands marine ecosystems. In these collaborative, interdisciplinary studies, he and his colleagues have investigated the causes of the spatial heterogeneity in the distribution, abundance, and foraging ecology of marine birds in the Aleutian Archipelago. An off-shoot of these studies has been the development of national and international programs for the investigation of how climate variability and warming may affect the sub-arctic seas.
