New paper in Journal of Animal Ecology

New paper about Antarctic seabirds, lead by Nina Dehnhard, just out in Journal of Animal Ecology. We combined GPS logging and stable isotopes to understand how Antarctica’s tremendous seasonal variability affected habitat and food segregation among closely related and sympatrically breeding species. Results suggest that all three species have a generalist behaviour and exhibit considerable isotopic niche overlap. This might be explained by the optimal foraging theory: in a very productive but highly variable such as coastal Antarctica, being a generalist, although it increases risks of interspecific competition, might be essential to efficiently exploit mobile prey stocks.
