Despite the fact that many animals live in groups, there is still no clear consensus about the
ecological or evolutionary mechanisms underlying colonial living. Recently, research has …

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

The oceans cover the majority of the Earth's surface; they influence our climate and provide
a valuable source of food to billions of people. Yet despite its fundamental impact on our …

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 …

During reproduction, seabirds need to balance the demands of self‐and offspring‐
provisioning within the constraints imposed by central place foraging. To assess behavioral …

Ward and Zahavi suggested in 1973 that colonies could serve as information centres,
through a transfer of information on the location of food resources between unrelated …

Key forage species lie at the core of complex marine food webs, providing essential linkages
among trophic levels. We examined the interactions of an important forage and commercial …

The foraging behaviour of animals depends on the distribution, abundance and
predictability of their food resources. In the marine environment, top predators such as …
