Dispersal is a central process in ecology and evolution. At the individual level, the three
stages of the dispersal process (ie, emigration, transience and immigration) are affected by …

This review focuses on the impacts of climate change on population dynamics. I introduce
the MUP (Measuring, Understanding, and Predicting) approach, which provides a general …

Site fidelity, or the behavior of returning to previously visited locations, has been observed
across taxa and ecosystems. By developing familiarity with a particular location, site fidelity …

We report on the first global census of the Adélie Penguin (Pygoscelis adeliae), achieved
using a combination of ground counts and satellite imagery, and find a breeding population …

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 …

Measurements of the size of Adélie penguin (Pygoscelis adeliae) colonies of the southern
Ross Sea are among the longest biologic time series in the Antarctic. We present an …

Unlike in many polar regions, the spatial extent and duration of the sea ice season have
increased in the Ross Sea sector of the Southern Ocean during the satellite era …

Extreme climatic conditions and their ecological impacts are currently emerging as critical
features of climate change. We studied extreme sea ice condition (ESIC) and found it …

There will be winners and losers as climate change alters the habitats of polar organisms.
For an Adélie penguin (Pygoscelis adeliae) colony on Beaufort Island (Beaufort), part of a …

Aim We hypothesized that regional spatial organization of Antarctic penguin breeding
populations was affected by social factors, that is, proximity and size of adjacent colonies …
