Climate change has opened region up for more of the year

Thousands of female penguins are being stranded along the coast of South America because of water pollution and fishing, research shows. A new study of Megellanic penguins, which breed in Patagonia in southern Argentina, explains for the first time why so many become stuck on beaches hundreds of miles further north.  Researchers found the man-made threats encountered as the

A 2008 report by the Canadian Food Inspection Agency said there were at least 486 invasive alien plant species alone in Canada.

The catch is shifting northward as water temperatures rise, forcing crews to retool their boats and rework their businesses. Pollock is retreating from Alaska while black sea bass throng around Rhode Island.

In 2016 and 2017 commercial fishers near Cambridge Bay in Nunavut were surprised when they pulled in sockeye salmon — because they were expecting to see only Arctic char. While these are just two fish, found far from their usual home waters, the two salmon are likely an indication that Pacific salmon will continue to

Polar bears, black bears, and grizzlies have been found together for the first time during a University of Saskatchewan research project in northern Manitoba.

This cute little guy makes you trip so hard you'll want to die, and could soon start popping up on the Gold Coast.

Crayfish were first observed on Kodiak around 2015. Now, a local tribal organization is studying their movement, distribution and diet.

Scientist warns of "seagrass crisis" in Caribbeans MEXICO CITY (Rahnuma): Massive quantities of Sargassum seaweed are invading Caribbean beaches mostly thanks to global warming and countries should work closely with scientists for a sustainable solution, said a researcher at a leading Mexican university on

A team of biologists is surveying a lake on Kodiak Island for crawfish, an invasive species in Alaska that has been observed in higher frequency over past several years.

From floods to fires, drought to coastal erosion, climate change is already having an impact on Canada's communities, landscapes and wildlife

Considered the most destructive pest slug in Europe, the Spanish slug, or Arion lusitanicus, or Arion vulgaris, or sometimes Geoff (there’s some controversy over the name, thanks to the fact that the Arion genus contains up to 50 species and they all look a lot like one another) is between 7-15cm long and can weigh up to 15kilos if it’s sitting on a dog.

Warmer temperatures and declining sea ice pulls foreign animals and plants to the Arctic, with drastic consequences for these sensitive ecosystems.

Climate change may be enabling beavers to move deeper into the Arctic. And as they move, they magnify climate change’s effects.

In August 2017, Sun’aq Tribe of Kodiak was awarded funding by USFWS Tribal Wildlife Grant (TWG) Program. The two-year project, titled “Distribution, Movement and Diet of Invasive Crayfish Populations in Buskin River Watershed on Kodiak Island, Alaska” focuses on characterizing the distribution (snorkel/scuba diving surveys), movement (radio tagging) and diet (stable isotope analyses) of the Signal Crayfish population within Buskin Watershed.

Climate change has warmed the waters east of Tasmania at four times the speed of the global average. But the heatwave of the southern summer of 2015/2016 was something exceptional, damaging fisheries and bringing new species to the island. It's a sign of things to come, say the researchers examining these events.

Keeping tabs on capelin — from the shores of the Atlantic ocean to the world wide web.

The Canada lynx, once eliminated from most of New England by forest clearing and unsustainable hunting and trapping, is making a comeback.

Like a horde of slimy green zombies, the incredibly invasive American bullfrog is hopping the border into the West Kootenay.
