Increased attention to species movement in response to environmental change highlights
the need to consider changes in species distributions and altered biological assemblages …

A widespread opinion is that conservation efforts disproportionately benefit charismatic
species. However, this doesn't mean that they are not threatened, and which species are …

Nineteen subpopulations of polar bears (Ursus maritimus) are found throughout the
circumpolar Arctic, and in all regions they depend on sea ice as a platform for traveling …

Polar bears are susceptible to climate warming because of their dependence on sea ice,
which is declining rapidly. We present the first evidence for a genetically distinct and …

Urbanization and associated environmental changes are causing global declines in
vertebrate populations. In general, population declines of the magnitudes now detected …

Satellite telemetry (ST) has played a critical role in the management and conservation of
polar bears (Ursus maritimus) over the last 50 years. ST data provide biological information …

Effective conservation planning requires understanding and ranking threats to wildlife
populations. We developed a Bayesian network model to evaluate the relative influence of …

Recent genomic analyses have provided substantial evidence for past periods of gene flow
from polar bears (Ursus maritimus) into Alaskan brown bears (Ursus arctos), with some …

The polar bear (Ursus maritimus) has become a symbol of the threat to biodiversity from
climate change. Understanding polar bear evolutionary history may provide insights into …

Grizzly bears have recently become more common on the Arctic Islands in the Inuvialuit
Settlement Region, concurrently with a period of environmental change. Over the last …
