Eurasian cuckoos, one of which is pictured here, are invading North America. Climate change has taken its toll on the Bering Strait's landscapes, which has made it easy for these birds to migrate to new lands. However, this could cause drastic declines of native bird populations.
Montana Fish, Wildlife and Parks' public-comment period for considering whether to restore bison herds to the state ends in late September. After that, the agency will be a bit closer to deciding yay or nay regarding a publicly-managed herd in the state.
Like in the Arctic, Antarctic and even Canada, glaciers in Alaska are melting. Now, new research reveals that like their famous brethren, they may make large contributions to global sea level rise.
For five years now, there has been a notable decline in the number of wolf sightings in Denali National Park and Preserve. Now a new report from the National Park Service (NPS) is suggesting that wolf hunting could be to blame, as there are few limitations on when a wolf can be killed by a hunter in the Alaskan wilderness.
Bison once freely roamed vast swaths of Canada and south-central Alaska, rarely, if ever, seeing a human hunter. However, by the late 1900s the animals were listed as endangered in Canada, and had disappeared entirely from Alaskan lands. Now a state-side initiative is bringing the bison back after a decades-long hiatus in an effort to repopulate the wild with these noble beasts.
Massive amounts of glacier melt and freshwater are pouring into the Gulf of Alaska, which may not seem like a big deal, but new research shows that this runoff can potentially have a drastic impact on both marine life to global sea level.
Every year, thousands of Pacific walrus gather to feed and raise their young along a shallow, 30-mile-long shelf off the coast of northwest Alaska. One of the Chukchi Sea's most biologically productive spots, it is an important feeding ground for bowhead whales too. And yet, it also happens to be just downstream from a number of oil and gas leases. Now, the US federal government is stepping in, granting new protections to ensure the safety of the spot.
A key polar bear population in Alaska has plummeted 40 percent in the last 10 years, marked by a dramatic increase in deaths of young cubs, according to a new study published Monday.
Climate scientists will be happy to hear that Alaska, despite large temperature increases in recent decades, is showing no signs of rising methane levels, at least for now.
Sea lions beware, Pacific sleeper sharks may have developed a bigger appetite, new research shows.
A band of 35,000 Pacific walrus are stranded in northwest Alaska, one of the last places they have to rest ashore, for melting Arctic ice is robbing them of their beach real estate, according to reports.
After disappearing from Alaska more than a century ago, wood bison are soon to return to the wilderness of the Last Frontier, according to officials.
Ocean acidification, as a result of carbon dioxide release into the air, could pose a risk to Alaska's valuable fisheries and communities, according to a recent NOAA-led study.
A high-definition camera aimed at an Arctic snowy owl nesting site in Alaska went live this week, providing researchers as well as the public with an unprecedented view into the den where six chicks are beginning to emerge.
