Abstract Since the last Arctic Monitoring and Assessment Programme (AMAP) effort to
review biological effects of the exposure to organohalogen compounds (OHCs) in Arctic …

Climate warming is causing unidirectional changes to annual patterns of sea ice distribution,
structure, and freeze‐up. We summarize evidence that documents how loss of sea ice, the …

Biodiversity is organised into complex ecological networks of interacting species in local
ecosystems, but our knowledge about the effects of habitat fragmentation on such systems …

Several recent climate impact assessments on polar regions have been undertaken,
including the synthesis report on Snow, Water, Ice and Permafrost in the Arctic (AMAP …

Polar bears (Ursus maritimus) require sea ice for capturing seals and are expected to
decline range-wide as global warming and sea-ice loss continue,. Estimating when different …

Abstract Changes in the abundance and distribution of wildlife populations are common
consequences of historic and contemporary climate change. Some Arctic marine mammals …

Declining Arctic sea ice is increasing polar bear land use. Polar bears on land are thought to
minimize activity to conserve energy. Here, we measure the daily energy expenditure (DEE) …

From the red grouse to the Ethiopian bush-crow, bird populations around the world can
provide us with vital insights into the effects of climate change on species and ecosystems …

Polar bears (Ursus maritimus) have experienced substantial changes in the seasonal
availability of sea ice habitat in parts of their range, including the Beaufort, Chukchi, and …

We are causing species to go extinct at extraordinary rates, altering existing species in
unprecedented ways, and creating entirely new species. More than ever before, we require …
