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 …

Energetic tidal-stream environments are characterized by frequent, variable, yet broadly
predictable currents containing ephemeral flow structures that change across multiple spatio …

Many established models of animal foraging assume that individuals are ecologically
equivalent. However, it is increasingly recognized that populations may comprise individuals …

Summary 1 We studied chick diet in a known‐age, sexed population of a long‐lived seabird,
the Brünnich's guillemot (Uria lomvia), over 15 years (N= 136; 1993–2007) and attached …

Breeding seabirds are extreme central-place foragers, commuting long distances between
colonies and feeding areas. Central-place foraging theory predicts that prey items close to …

Coastal kelp forest ecosystems provide important habitats for a diverse assemblage of
invertebrates, fish and marine top-predators such as seabirds and sea mammals. Although …

Long-finned pilot whales (Globicephala melas), Risso's dolphins (Grampus griseus), melon-
headed whales (Peponocephala electra), Cuvier's beaked whales (Ziphius cavirostris) …

Sexual segregation, common in many species, is usually attributed to intra-specific
competition or habitat choice. However, few studies have simultaneously quantified sex …

While decreases in Arctic sea ice affect all marine communities in the Arctic Basin, the
effects are greatest on the cryopelagic ecosystem and species with critical life history stages …

The presence of sex-stereotyped behavior in monomorphic animals, where there are no
sexual differences in form to account for sexual differences in function, is often attributed to …
