The use of measurements of naturally occurring stable isotopes of the light elements C, N, H,
O, S in avian tissues and their associated foodwebs has grown tremendously during the last …

Accounting for migration and connectivity of mobile species across the annual cycle can
present challenges for conservation and management efforts. The use of stable isotope …

Background Tracking small migrant organisms worldwide has been hampered by
technological and recovery limitations and sampling bias inherent in exogenous markers …

Stable isotopes of carbon and nitrogen can provide valuable insight into seabird diet, but
when interpreting results, seabird biologists need to recognize the many assumptions and …

There is an overdue and urgent need to establish patterns of migratory connectivity linking
breeding grounds, stopover sites, and wintering grounds of migratory birds. Such …

We investigated the relationships between the δdeuterium (δD) and the δ18oxygen (δ18O)
of drinking water and the δD and δ18O of blood plasma, red blood cells and feathers in …

Management decisions involving species at risk are typically made in the face of substantial
biological uncertainty. Incorporating uncertainty into decision-making allows managers to …

In North America, gradients in the ratio of stable hydrogen isotopes in amount-weighted,
growing-season mean precipitation (2H: 1H; depicted as δ2Hp) form a largely latitude …

Comparative equilibration has been proposed as a methodological approach for
determining the hydrogen isotopic composition (δD) of non‐exchangeable hydrogen in …

Stable-hydrogen isotope ratios (deuterium: protium; δD) in feathers enable researchers to
evaluate patterns of avian movement and to estimate the source areas of migratory birds …
