We review present understanding of the spatial and temporal diet variability
(trophodynamics) of a range of pelagic marine top predators, at both early and adult life …

Understanding the determinants of species' distributions is a fundamental aim in ecology
and a prerequisite for conservation but is particularly challenging in the marine environment …

Seabirds have been used extensively as bioindicators of mercury (Hg) contamination in the
marine environment, although information on flightless species like penguins remains …

Protection of the marine environment lags far behind that of terrestrial domains. To help
ameliorate this circumstance, top predators are being tracked to identify important ocean …

Mercury (Hg) contamination poses potential threats to ecosystems worldwide. In order to
study Hg bioavailability in the poorly documented southern Indian Ocean, Hg exposure was …

Penguins have been recently identified as useful bioindicators of mercury (Hg) transfer to
food webs in the Southern Ocean over different spatial and temporal scales. Here, feather …

When species competing for the same resources coexist, some segregation in the way they
utilize those resources is expected. However, little is known about how closely related …

Background Sexual segregation in vertebrate foraging niche is often associated with sexual
size dimorphism (SSD), ie, ecological sexual dimorphism. Although foraging behavior of …

Ecological niche theory predicts segregation mechanisms that mitigate potential competition
between closely related organisms. However, little is known outside the breeding season …

Climate shifts are key drivers of ecosystem change. Despite the critical importance of
Antarctica and the Southern Ocean for global climate, the extent of climate-driven ecological …
