Arctic marine mammals (AMMs) are icons of climate change, largely because of their close
association with sea ice. However, neither a circumpolar assessment of AMM status nor a …

This review critically evaluates the available mercury (Hg) data in Arctic marine biota and the
Inuit population against toxicity threshold values. In particular marine top predators exhibit …

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

The strict orthology of mitochondrial (mt) coding sequences has promoted their use in
phylogenetic analyses at different levels. Here we present the results of a mitogenomic study (ie, …

Projections of polar bear ( Ursus maritimus ) sea ice habitat distribution in the polar basin
during the 21st century were developed to understand the consequences of anticipated sea ice …

Polar bears are uniquely adapted to life in the High Arctic and have undergone drastic
physiological changes in response to Arctic climates and a hyperlipid diet of primarily marine …

Perfluoroalkyl substances were determined in liver tissues and blood of polar bears (Ursus
maritimus) from five locations in the North American Arctic and two locations in the European …

Polar bears (Ursus maritimus) are exposed to high concentrations of mercury because they
are apex predators in the Arctic ecosystem. Although mercury is a potent neurotoxic heavy …

The exploitation and conservation status of Atlantic walruses (Odobenus rosmarus rosmarus
1.) has never become an issue of widespread public contro versy, as it has for whales, and …

Rapid climate changes are occurring in the A rctic, with substantial repercussions for arctic
ecosystems. It is challenging to assess ecosystem changes in remote polar environments, but …
