Food sources of wintering piscivorous waterbirds in coastal waters: a triple stable isotope approach for the southeastern Baltic Sea
This study uses a triple isotope approach (δ13C, δ15N, and δ34S) to quantify the main food sources for wintering piscivorous waterbirds in the coastal zone of the southeastern Baltic Sea. Significant differences of δ15N and δ34S values among pelagic fishes, benthic fishes, and benthopelagic European...
