Chum salmon spawning in the Arctic may provide food for native fish species, helping them survive in the biologically unproductive waters, as scientists study the changing ecology of the region due to warming temperatures.

Most of the humpbacks were seen near the Inupiat village of Point Hope, indicating a feeding hotspot in that area. While sightings farther north have been less numerous, there has still been an increase in recent years. The study suggests that climate change and the reduction of Arctic sea ice may be a factor in the expansion of humpback whale range.

Common garter snakes are no longer rare in southwestern Newfoundland, and researchers are conducting genetic work to determine their origin.

Moose in Southeast Alaska are being harvested in new areas, indicating a potential expansion of their population and distribution.

A "weed smackdown" at an Anchorage park is part of a long-running campaign to stop the spread of plants that are harming the natural ecosystem.

An invasive species of mollusks, typically found in Southeast Alaska and established in Girdwood in 2015, have been reported in the Anchorage Bowl this year. “The European black slug is not necessarily new to Alaska,” Slowik said. “It was introduced into Cordova about the 1980s and it really stayed there for a long time.”

Now, for the first time, researchers have concrete evidence that northern pike could use the ocean to move between freshwater Alaska habitats.

Those studying ticks in Alaska currently are more concerned about non-native ticks hitching a ride on pets that arrive in the state from Outside, and infecting wildlife here.

Homer police confirmed the Wednesday capture of the “wanted fugitive and somewhat local celebrity," otherwise known as an invasive species.

Arctic Foxes are curious animals of the North and often will befriend humans and not be afraid. Often times they move into other fox areas and territory.

Charitie Ropati, 21, wants to reimagine scientific research to include her traditional values, like community and collective wellbeing.

Many hikers in Southern Alberta head to the trails in spring equipped with bear spray, singing or saying hey bear, woah bear, to warn the animal they're around the corner. Elders and knowledge keepers from Stoney Nakoda Nations have their own approach, and lessons to share when it comes to co-existence.

Efforts to encourage Icelandic fisheries to make use of Atlantic bluefin tuna catch quotas allotted to Iceland have yet to prove fruitful. While tuna goes for high prices, specialised ships are necessary to make tuna fishing profitable. Chartering foreign boats to develop tuna fishing experience within the Icelandic fishing industry would require authorisation from the […]

Scientists are studying the diets of the oceans’ top predators as they change in response to their environments. This is because how much and what they eat can affect how ecosystems function.

Climate change is affecting all aspects of our land, and also what flies in our sky. Bird migration is changing as average temperatures rise. So what does that mean for our bird species?

The number of dogs testing positive for tick-borne illnesses has nearly doubled this year, says a Nova Scotia veterinarian. Jeff Goodall, the owner and a veterinarian at Sunnyview Animal Care, said the problems go beyond Lyme disease. Anaplasmosis is also a concern. He said dogs have been testing positive for tick-borne illnesses throughout the winter.

All the birds were gone. Now there is full life in the bird cliffs again. The researchers believe they have found the explanation for the mystery.

Researchers will be stepping up their efforts to track chronic wasting disease in Saskatchewan's north.

Scientists say climate change appears to be a factor making Florida and other parts of the U.S. welcoming to non-native mosquitoes.

With ice declining, bowhead whales of the Pacific Arctic choose to stay longer in the waters up north. A change in migration patterns could affect the bowheads' health and safety, as well as the hunters' access to the subsistence resource.
