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 …

There is increasing recognition of the importance of “positive interactions” among species in
structuring communities. For seabirds, an important kind of positive interaction is the use of …

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 …

Reducing resource competition is a crucial requirement for colonial seabirds to ensure
adequate self‐and chick‐provisioning during breeding season. Spatial segregation is a …

Pelagic seabirds exhibit plasticity in foraging characteristics in relation to oceanographic
conditions. This should be particularly relevant in tropical marine environments where food …

Gonatus fabricii is the most abundant cephalopod species in Arctic waters, and the only
squid that completes its entire life cycle there. In order to understand its ecological role in the …

Detailed information on diet and foraging ecology is scarce for most small seabirds such as
storm petrels. In this study, we used molecular techniques, stable isotope analysis, and …

Two species breeding in sympatry are more likely to coexist if their ecological niches are
segregated either in time, space or in trophic habits. Here, we combined GPS-tracking …

Hawksbill sea turtles are the most tropical sea turtle species with one of the last remaining
aggregations in West Africa found on Príncipe Island (1° 37′ N; 7° 23′ E). Here we …

Knowledge about sexual segregation and gender-specific, or indeed individual
specialization, in marine organisms has improved considerably in the past decade. In this …
