The Antarctic Peninsula is experiencing one of the fastest rates of regional climate change
on Earth, resulting in the collapse of ice shelves, the retreat of glaciers and the exposure of …

Over the last century, major climate changes and intense human exploitation of natural living
resources have occurred in the Southern Ocean, potentially affecting its ecosystems up to …

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 …

The prediction of crustal motions and gravity change driven by glacial isostatic adjustment
(GIA) in Antarctica is critically dependent on the reconstruction of the configuration and …

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 …

The Weddell seal is one of the best-studied marine mammals in the world, owing to a
multidecadal demographic effort in the southernmost part of its range. Despite their …

Stable isotope values of carbon (δ13C) and nitrogen (δ15N) in blood, feathers, eggshell,
and bone have been used in seabird studies since the 1980s, providing a valuable source …

Predicting the dynamics of ecosystems requires an understanding of how trophic
interactions respond to environmental change. In Antarctic marine ecosystems, food web …

1. Heterogeneity in individual quality (ie individuals having different performance levels that
are consistent throughout life) can drive the demography of iteroparous species, but quality …

Well-preserved remains of bone, tissue, and eggshell of Adélie Penguin (Pygoscelis
