Journal ArticleDOI
Short-term effects of data-loggers on Cory’s shearwater (Calonectris diomedea)
José Manuel Igual,Manuela G. Forero,Giacomo Tavecchia,Jacob González-Solís,Jacob González-Solís,Alejandro Martínez-Abraín,Keith A. Hobson,Xavier Ruiz,Daniel Oro +8 more
TL;DR: Results suggest that the use of loggers is an adequate methodology to obtain information from seabirds at sea, but data should be carefully interpreted with regard to potential biases during severe environmental conditions.
Journal ArticleDOI
Isotopic reconstruction of marine food webs using cephalopod beaks: new insight from captively raised Sepia officinalis
TL;DR: Cuttlefish beaks showed little isotopic enrichment over the diets at the time of beak formation, with the beak rostral tips representing the neonatal diet and the remaining beak material representing the adult (shrimp) diet.
Journal ArticleDOI
Re-evaluation of the hydrogen stable isotopic composition of keratin calibration standards for wildlife and forensic science applications
TL;DR: For routine H isotope analyses, the Comparative Equilibration approach can provide accurate and reproducible non-exchangeable δ2 H values among laboratories regardless of the reactor type used.
Journal ArticleDOI
Stable isotopes (δD) delineate the origins and migratory connectivity of harvested animals: the case of European woodpigeons
Keith A. Hobson,Hervé Lormée,Steven L. Van Wilgenburg,Leonard I. Wassenaar,Jean Marie Boutin +4 more
TL;DR: This paper used a stable hydrogen isotope (δ D) isoscape for Europe and δ D analysis of feathers from harvested woodpigeons Columba palumbus in France, the Iberian Peninsula, and Corsica to estimate their natal origins.
Journal ArticleDOI
The Role of Fruits and Insects in the Nutrition of Frugivorous Bats: Evaluating the Use of Stable Isotope Models1
TL;DR: It is suggested that future studies better define isotopic fractionation between diet and tissues of bats using captive rearing and controlled diets.
