Co-occurring species with similar resource requirements often partition ecological niches. In the Northwest Atlantic (NWA), endangered roseate terns (Sterna dougallii) nest almost exclusively in coastal island colonies alongside common terns (S. hirundo). Roseate terns are prey specialists compared to common terns, which are opportunistic generalists; however, the two species forage on similar resources during the breeding season. The degree to which these species overlap in their adult foraging ecologies is not well understood. We compared the isotopic niches of nesting adult roseate and common terns by analyzing stable carbon (δ13C) and nitrogen (δ15N) isotopes in eggshell membrane tissues collected in 2018 and...

Relatively little is known about the distribution, abundance and spatio-temporal variability of marine birds in their habitats of the Eastern coast of the U.S. A number of surveys have been conducted over the last 10-15 years, but analyzing these data in a unifed framework is difficult due to the use of different sampling methods, spatial and temporal scales, as well as lack of sampling design. Thus, we incorporate a multi-scale approach to develop models for the space-time distribution and abundance of marine birds to identify potential high-use areas in need of further study. With data taken from past and ongoing survey efforts, we provide relative abundance and density estimates for marine birds over a wide geographical...

This data product was created for the project titled: “Application of the Coastal and Marine Ecological Classification Standard (CMECS) to the Northwest Atlantic” which was partially funded by the U.S. Department of the Interior, Fish and Wildlife Service and a joint collaborative project with The Nature Conservancy (Eastern Division Conservation Science), University of Rhode Island (Graduate School of Oceanography), and Massachusetts Department of Fish and Game (Division of Marine Fisheries). In the Northeast United States region, efforts are underway to better organize and integrate spatial marine data to support ocean planning and management efforts. An important step in this process is translating existing...
