The development of the isotopic niche, an n-dimensional hypervolume (with n being the
number of isotopes) occupied by a population in delta space, has revolutionized the study of …

Though climate change is widely known to negatively affect the distribution and abundance
of many species, few studies have focused on species that may benefit. Gentoo Penguin …

Under the climate change context, warming Southern Ocean waters may allow mercury (Hg)
to become more bioavailable to the Antarctic marine food web (ie, ice-stored Hg release and …

Global targets for area-based conservation and management must move beyond threshold-
based targets alone and must account for the quality of such areas. In the Southern Ocean …

Abstract Persistent Organic Pollutants (POPs) are a global threat, but impacts of these
chemicals upon remote areas such as Antarctica remain unclear. Penguins can be useful …

In this study, we investigated factors that influence the differences in exposure of
perfluoroalkyl acids (PFAAs) from eight species of Antarctic seabirds, including Pygoscelis …

Direct observation of foraging behavior is not always possible, especially for marine species
that hunt underwater. However, biologging and tracking devices have provided detailed …

Background Energy landscapes provide an approach to the mechanistic basis of spatial
ecology and decision-making in animals. This is based on the quantification of the variation …

Penguins in Antarctica occupy high trophic levels, thus accumulating high amounts of
mercury (Hg) through bioaccumulation and biomagnification. Blood reflects the current …

As climate change, among other factors, is increasingly affecting Antarctic marine systems,
competition for prey may increase between predators, particularly in the Antarctic Peninsula …
