BACKGROUND Comparing patterns of terrestrial and marine defaunation helps to place
human impacts on marine fauna in context and to navigate toward recovery. Defaunation …

Recent advances in animal tracking and telemetry technology have allowed the collection of
location data at an ever-increasing rate and accuracy, and these advances have been …

Background Identification of key foraging habitats of aquatic top predators is essential for
designing effective management and conservation strategies. The Baltic ringed seal (Phoca …

In large marine predators, foraging entails movement. Quantitative models reveal how
behaviours can mediate individual movement, such that deviations from a random pattern …

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 …

Ecosystem regime shifts can have severe ecological and economic consequences, making
it a top priority to understand how to make systems more resilient. Theory predicts that …

In environments with high spatiotemporal variability in resources, animals may exhibit
nomadic movements for resource tracking as opposed to long-term area fidelity. Polar bears …

To investigate how a generalist marine predator modifies its foraging behaviour by prey
type, we attached time-depth-temperature recorders to chick-rearing thick-billed murres (n …

Classifying movement behaviour of marine predators in relation to anthropogenic activity
and environmental conditions is important to guide marine conservation. We studied the …
