Combining aerial survey data for forage fish and seabirds to determine how shifts in forage fish distributions contribute to predator distributions.Using satellite telemetry data to describe the movements of Northern Gannets, Red-throated Loons, and Long-tailed Ducks and determine how forage fish availability influences movement behavior.Compiling digital aerial survey data of forage fish shoals in the Mid-Atlantic and New York Bight to understand the oceanographic factors that lead to forage fish shoals.In order to better understand how prey availability influences predator behavior, distributions, and long-term trends, this study includes: Different tools are often needed to describe patterns in predators and prey. Studying trophic relationships in the marine environment is particularly difficult due to the remote and variable natures of these ecosystems. In order to address this need, BRI is collaborating with scientists at NOAA, USGS, and Memorial University of Canada to investigate the importance of predator-prey relationships in the marine environment.īRI Lead Investigators: Evan Adams, Julia Gulka, Chandra Goetsch, Andrew Gilbert, Iain Stenhouse, Kate Williams More information is needed in order to strengthen our understanding of trophic interactions in ocean habitats, so we can better understand human influence on the marine environment. continues to promote offshore wind energy development in its coastal waters, BRI researchers are studying how these developments may affect the patterns and processes that influence wildlife distributions, and how those effects could result in changing food webs. Marine ecosystems are complex and dynamic-changes in water temperature, currents, and other factors can alter the distributions of marine fish and wildlife in many ways.
