resources, is a dramatic behaviour and an important component of many life histories that …

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 …

Patterns of animal movement associated with foraging lie at the heart of many ecological
studies and often animals face decisions of staying in an environment they know versus …

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 …

Highly pelagic large marine vertebrates have evolved the capability of moving across large
expanses of the marine environment; some species routinely move across entire ocean …

Abstract Changes in phenology and distribution are being widely reported for many
migratory species in response to shifting environmental conditions. Understanding these …

Seasonal long-distance migration is likely to be experienced in a contrasted manner by
juvenile, immature and adult birds, leading to variations in migratory routes, timing and …
