The development of the isotopic niche, an n-dimensional hypervolume (with n being the
number of isotopes) occupied by a population in delta space, has revolutionized the study of …

Trophic relationships are a central theme in ecology and play a crucial role in the survival of
organisms, because the availability of food resources varies over time and space. Until …

Technological advances in recent years have seen an explosion of tracking and stable
isotope studies of seabirds, often involving repeated measures from the same individuals …

Considerable attention has focused on inter-and intraspecific variation in trophic niches of
marine predators. Although this has revealed evidence for sexual segregation in distribution …

Ecological theory predicts that animals with similar foraging strategies should not be able to
co‐exist without segregating either in space, time or diet. In communities, intra‐specific …

Understanding seabird marine habitat affinities, at-sea behavior, variability in reproductive
success, migratory patterns, phenology, and other life history traits depends primarily on …

Background During the non-breeding period, many birds migrate to milder areas, found
closer to the equator than their breeding sites. Opposite movements are very rare. In the …

Niche variation is a widespread phenomenon that has important implications for ecological
interactions and conservation biology, but few studies have quantified the trophic niche …

The wandering albatross (Diomedea exulans) is regarded as a generalist predator, but can
it be consistent in its foraging niche at an individual level? This study tested short-and long …

The foraging ecology of small seabirds remains poorly understood because of the difficulty
of studying them at sea. Here, the extent to which 3 sympatric seabirds (blue petrel, thin …
