Millions of bats in the Eastern US and the Midwest have died from white nose syndrome disease, and it’s spreading.

Lack of food means bears cannot hibernate, and die of starvation and cold, with logging blamed for the lack of nuts and acorns.

The most recent study noted that Arctic thaw is occurring one to two weeks earlier than the first study, and the North Slope growing season is lengthening by 15 to 21 days. At the same time, however, caribou are maintaining the same reproductive timeline.

Reindeer stuck in local trash. Blue markings can also be seen on body. Mayor Frank M. Ingilæ and his two dogs came to the rescue for this fight Wednesday.

A big emphasis in the last few years has been updating and adding to the list of species known to occur in the Yukon. This past year, a whopping 1,973 species of plants, insects and animals have been added.

As lichen has disappeared, the herd has changed its diet. This adaptation could have global implications for reindeer facing a warming climate.

The Yukon Fish and Game Association executive director believes it's just a matter of time before a disease outbreak, such as pneumonia, could spread from domestic sheep to wild Dall sheep.

The average weight of adult reindeer on Svalbard, north of Norway, has fallen to 106 pounds from 121 pounds in the 1990s

Two extreme weather events in 2006 and 2013 caused mass starvation among the reindeer herds, and researchers for the first time have linked these extreme weather events in the coastal mainland in northwest Russia with sea ice loss in the adjoining Barents and Kara seas.
