The massive number of seabirds (penguins and procellariiformes) and marine mammals
(cetaceans and pinnipeds)–referred to here as top predators–is one of the most iconic …

Penguins face a wide range of threats. Most observed population changes have been
negative and have happened over the last 60 years. Today, populations of 11 penguin …

High-latitude pelagic marine ecosystems are vulnerable to climate change because of the
intertwining of sea/continental ice dynamics, physics, biogeochemistry, and food-web …

Colonially-breeding seabirds have long served as indicator species for the health of the
oceans on which they depend. Abundance and breeding data are repeatedly collected at …

Polar bears (Ursus maritimus) are subjected to several anthropogenic threats, climate
warming and exposure to pollutants being two of these. For polar bears, one of the main …

Abstract We developed a Hidden Markov mark–recapture model (R package marked) to
examine sex‐specific demography in Magellanic Penguins (Spheniscus magellanicus). Our …

Understanding the scales at which environmental variability affects populations is critical for
projecting population dynamics and species distributions in rapidly changing environments …

Abstract In the Ross Sea, biodiversity organisation is strongly influenced by sea-ice cover,
which is characterised by marked spatio-temporal variations. Expected changes in seasonal …

Climate change is increasing the frequency of extreme events, such as droughts or
hurricanes, with substantial impacts on human and wildlife communities. Extreme events …

Abstract The Ross Sea Marine Protected Area (RS-MPA) hosts endemic species that have to
cope with multiple threats, including chemical contamination. Adèlie penguin is considered …
