Rather than using their historical migratory stopovers, Barnacle geese (Branta leucopsis) have begun making nonstop journeys from the Netherlands to their Arctic breeding grounds. Scientists say the reason is climate...

With declines in sea ice that polar bears (Ursus maritimus) in the arctic require to subsist, researchers have seen accounts of bears traveling farther north. But what do these longer...

Humans may not be the only culprits in climate change. The New York Times reports that as the arctic warms, beavers (Castor canadensis) are expanding their range north. The dams...

Arctic shorebird populations have been dwindling for more than a decade, but recent research suggests that habitat loss and other factors along their migratory routes may be more responsible for...

Climate change hasn’t been kind to the polar bear (Ursus maritimus), which has seen its traditional habitat dwindle as sea ice melts. But the rising mercury in thermometers in the...

Scientists have been tracking the migration of the semipalmated sandpiper (Calidris pusilla) to trace the origins of its population in northeastern South American, which is decreasing dramatically. A new study...

Parasites don’t get much respect, but researchers have found they can offer important clues about climate change. As Arctic temperatures warm, recent research suggests, parasites in small mammals such as...

As the climate warms and permafrost thaws, some tundra dwellers might be helping cool the planet. By grazing heavily and decreasing the height and prevalence of shrubs, reindeer (Rangifer tarandus)...

For years, the polar bear (Ursus maritimus) has been the posterchild of climate change, but recent research reveals that the species also faces a serious threat from a host of...

Coupled with threats such as habitat destruction and climate change in Alaska’s Arctic, high levels of mercury discovered recently in shorebirds could create further challenges for the species. In a...
