The massive number of seabirds (penguins and procellariiformes) and marine mammals
(cetaceans and pinnipeds)–referred to here as top predators–is one of the most iconic …

Managing fisheries in an ecologically sensitive manner demands that catches do not
depress stocks within the foraging areas used by predators to levels that reduce their …

Determining the links between the behavioural and population responses of wild species to
environmental variations is critical for understanding the impact of climate variability on …

Corticosterone has received considerable attention as the principal hormonal mediator of
allostasis or physiological stress in wild animals. More recently, it has also been implicated …

Ecological theory predicts that animals with similar foraging strategies should not be able to
co‐exist without segregating either in space, time or diet. In communities, intra‐specific …

Climate change and overfishing are increasingly causing unanticipated changes in marine
ecosystems (eg shifts in species dominance). In order to understand and anticipate these …

In animal populations, a minority of individuals consistently achieves the highest breeding
success and therefore contributes the most recruits to future generations. On average …

How predators find, select and capture prey is central to understanding trophic cascades
and ecosystem structure. But despite advances in biologging technology, obtaining in situ …

Determining where, when and how much animals eat is fundamental to understanding their
ecology. We developed a technique to identify a prey capture signature for little penguins …

Dramatic decreases of chinstrap penguin populations across the Antarctic Peninsula (AP)
are thought to be influenced by climate-driven changes affecting its main prey, the Antarctic …
