There are several reasons barren-ground caribou populations in Canada have declined more than 70 per cent over the past two decades, but too much hunting by Indigenous people is not one of them, a new University of Alberta-led study shows.

For the past 40 years, the total number of Adélie Penguins, one of the most common on the Antarctic Peninsula, has been steadily declining—or so biologists have thought. A new study led by researchers from the Woods Hole Oceanographic Institution (WHOI), however, is providing new insights on of this species of penguin.

When Brady Highway first arrived in Churchill, Manitoba in November 2013 to begin a new position with Parks Canada, it was the morning after a polar bear attacked and seriously injured two people. The event made national headlines.

A new study by the Wildlife Conservation Society (WCS) and Foundations of Success (FOS) finds that an ecotourism strategy based on “direct payments,” where local people are compensated for the amount of wildlife seen by tourists, has resulted in a reduction in illegal hunting and an increase in wildlife sightings.

Papped snaffling in the jungle, a striking set of photos reveal the secret lives of Amazonian crop-raiding animals.

Accurate numbers are the cat’s pyjamas when it comes to solving the current cat population crisis. But measuring the feline population has been difficult, until now.

In the future of wildlife tracking, sea otters have their own social network.

Whereas we might carry cell phones or tablets, each sea otter has a small, solar-powered tag clipped carefully to one of its flippers. When the sea otters gather to nap at the ocean’s surface, their tags boot up, and check in with one another. Who else did the sea otter interact with today, where, and when?

As far as anyone can tell, the cold-water crayfish Faxonius eupunctus makes its home in a 30-mile stretch of the Eleven Point River and nowhere else in the world. According to a new study, the animal is most abundant in the middle part its range, a rocky expanse in southern Missouri – with up to 35,000 cubic feet of chilly Ozark river water flowing by each second.

The reality of climate change poses a significant threat to global biodiversity. As temperatures rise, the survival of individual species will ultimately depend on their ability to adapt to changes in habitat and their interactions with other species.

Jellyfish blooms are becoming more widespread and scientists are looking for ways to understand them better, including their impact on species like salmon that compete with them for food sources. Now, researchers at the University of British Columbia have enlisted aerial drones to track these jellyfish clusters, their behaviours, and populations in greater detail.
