Factors That Influence Assimilation Rates and Fractionation of Nitrogen and Carbon Stable Isotopes in Avian Blood and Feathers
By switching great skuas Catharacta skua from one isotopically distinct diet to another, we measured diet‐tissue discrimination factors and tested the assumption that dietary nitrogen and carbonExpand

Diet studies of seabirds: a review and recommendations
We review the different methods that are used to collect dietary data from marine birds. We consider their limitations and practicalities and emphasize critical data gaps in our knowledge of theExpand

Assortative Mating as a Mechanism for Rapid Evolution of a Migratory Divide
There have been numerous recent observations of changes in the behavior and dynamics of migratory bird populations, but the plasticity of the migratory trait and our inability to track small animalsExpand

Using bird feathers to measure mercury in the environment: Relationships between mercury content and moult
Abstract Feathers can be used to monitor mercury levels in marine, freshwater and terrestrial ecosystems. Previous studies have often failed to take into account the great differences in mercuryExpand

Birds as monitors of pollutants
Several authors of books on the monitoring of pollution have advocated the use of animals as monitors in terrestrial and aquatic environments (e.g. Phillips, 1980; Schubert, 1985). Such studies tendExpand

Seabirds as monitors of the marine environment
Many studies have shown that seabirds are sensitive to changes in food supply, and therefore have potential as monitors of fish stocks. For most seabird species breeding parameters suitable forExpand

Natural temperature regimes for loggerhead and green turtle nests in the eastern Mediterranean
Temperatures of green turtle (Chelonia mydas) and loggerhead turtle (Caretta caretta) nests on the beaches of northern Cyprus and Turkey were examined. Electronic continuous-temperature recordersExpand

Global Seabird Response to Forage Fish Depletion—One-Third for the Birds
One-third of maximum fish biomass must be available for seabirds to sustain high breeding success. Determining the form of key predator-prey relationships is critical for understanding marineExpand

A forensic approach to understanding diet and habitat use from stable isotope analysis of (avian) claw material
Summary 1. The potential of using stable isotope signatures of avian claws in order to infer diet and habitat use was investigated. 2. Highly significant relationships observed between stable carbonExpand
