The notion that men are more variable than women has become embedded into scientific
thinking. For mental traits like personality, greater male variability has been partly attributed …

Colonial seabirds are relatively easy to observe, count, measure and manipulate, and
consequently have long been used as models for testing ecological hypotheses. A …

Westerly winds in the Southern Ocean have increased in intensity and moved poleward.
Using long-term demographic and foraging records, we show that foraging range in …

The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Sexual segregation by micro–or macrohabitat is common in birds, and usually attributed to
size–mediated dominance and exclusion of females by larger males, trophic niche …

The extent of increasing anthropogenic impacts on large marine vertebrates partly depends
on the animals' movement patterns. Effective conservation requires identification of the key …

Many birds show a surprising degree of intraspecific variability in migratory tendency and
choice of wintering site. In this study, we tracked the seasonal movements of 35 …

How does an animal age in natural conditions? Given the multifaceted nature of
senescence, identifying the effects of age on physiology and behavior remains challenging …

Considerable attention has focused on inter-and intraspecific variation in trophic niches of
marine predators. Although this has revealed evidence for sexual segregation in distribution …

Abstract Information on predator and prey distributions is integral to our understanding of
migratory connectivity, food web dynamics and ecosystem structure. In marine systems …
