Reproductive performance typically improves with age, reaching a plateau at middle age
and subsequently declining in older age classes (senescing individuals). Three potential …

Competition for food resources can result in spatial and dietary segregation among
individuals from the same species. Few studies have looked at such segregations with the …

Abstract Chiaradia, A., Forero, MG, Hobson, KA, and Cullen, JM 2010. Changes in diet and
trophic position of a top predator 10 years after a mass mortality of a key prey.–ICES Journal …

Group foraging provides predators with advantages in over-powering prey larger than
themselves or in aggregating small prey for efficient exploitation. For group-living predatory …

Coastal developments are ever‐expanding and increasing the use of artificial lights within
marine environments. Yet there is conflicting research on the impact of artificial lights on …

Breeding animals face important time and energy constraints when caring for themselves
and their offspring. For long‐lived species, life‐history theory predicts that parents should …

Age-related changes in breeding performance are likely to be mediated through changes in
parental foraging performance. We investigated the relationship of foraging performance …

Central-place foraging in large seabird colonies leads to high levels of intra-specific
competition for food resources, often resulting in between-colony spatial segregation …

Although the impact of environmental changes on the demographic parameters of top
predators is well established, the mechanisms by which populations are affected remain …

The presence of humans within the natural environment is increasing worldwide. Assessing
the impact of such activities on wildlife is crucial for declining populations where human …
