Combining bulk stable H isotope (δ2H) measurements with fatty acid profiles to examine differential use of aquatic vs. terrestrial prey by three sympatric species of aerial insectivorous birds
TL;DR: In this paper , the stable hydrogen isotope (δ2H) values of feathers and bulk blood plasma fatty acids of nestling purple martins (Progne subis), tree swallows, Tachycineta bicolor, and barn swallows (Hirundo rustica) were compared at lakeshore and inland sites near Lake Erie, Ontario, Canada.
Journal ArticleDOI

Renata D. Alquezar,Fábio J.V. Costa,João Paulo Sena-Souza,Gabriela Bielefeld Nardoto,Keith A. Hobson +4 more
TL;DR: In this paper , the authors developed a feather hydrogen isotope (δ2Hf) isoscape for Brazil based on 192 samples of feathers from the family Thraupidae from scientific collections.
Journal ArticleDOI

TL;DR: In this article , the authors measured stable isotopes of feathers grown on the wintering grounds of European turtle doves and used a dual-isotope (hydrogen ( δ 2 H f ) and carbon (� 13 C f )) probabilistic assignment to analyse origins of individuals migrating through the western and central/eastern flyways.
Journal ArticleDOI
Multidimensional natal isotopic niches reflect migratory patterns in birds.
A. Franzoi,A. Franzoi,S. Larsen,Pietro Franceschi,Keith A. Hobson,Paolo Pedrini,Federica Camin,Federica Camin,Luana Bontempo +8 more
TL;DR: In this article, the authors measured stable isotope ratios in animal tissues to estimate species trophic position and ecological niche, and found no relationship between species breeding NB and population trends in Europe, suggesting that conditions in the breeding grounds are not the only determinant of species' long-term persistence.
