From the red grouse to the Ethiopian bush-crow, bird populations around the world can
provide us with vital insights into the effects of climate change on species and ecosystems …

The Ideal Free Distribution theory predicts a close spatial match between predators and
prey. Studies have shown that seabird and prey distribution seldom conforms with this …

It is generally assumed that the extreme life history traits of pelagic seabirds, such as low
fecundity or slow growth of chicks, result from the difficulties obtaining energy at sea from …

Colonial breeding is widespread among animals. Some, such as eusocial insects, may use
agonistic behavior to partition available foraging habitat into mutually exclusive territories; …

Penguins are adapted to live in extreme environments, but they can be highly sensitive to
climate change, which disrupts penguin life history strategies when it alters the weather …

We report on the first global census of the Adélie Penguin (Pygoscelis adeliae), achieved
using a combination of ground counts and satellite imagery, and find a breeding population …

In the Southern Ocean, several zooplankton taxonomic groups, euphausiids, copepods,
salps and pteropods, are notable because of their biomass and abundance and their roles …

We assess the response of pack ice penguins, Emperor (Aptenodytes forsteri) and Adélie
(Pygoscelis adeliae), to habitat variability and, then, by modeling habitat alterations, the …

Density-dependent prey depletion around breeding colonies has long been considered an
important factor controlling the population dynamics of colonial animals. 1–4 Ashmole …

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 …
