University of Adelaide researchers have discovered how grapes “breathe”, and that shortage of oxygen leads to cell death in the grape. 

As ice the melts, the organic carbon found in permafrost is being released once again after ages of confinement in the soil. It is making its way into Arctic and subarctic lakes and ponds, and modifying their composition. The portrait presented by an international team of researchers that includes Professor Isabelle Laurion of INRS shows the influence that thawing permafrost has on surface water biogeochemistry. Published in Limnology and Oceanography Letters, the results demonstrate that organic carbon from permafrost is making its way into the waters of these regions. This type of carbon is particularly good at absorbing sunlight. As a result, these water bodies are getting increasingly darker and stratified, which affects a number of biological processes in these ecosystems.

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.

Across the globe, billions of dollars are spent annually on repairing ecosystems damaged by people. Forests denuded by logging. Rivers polluted by industry. Grasslands converted to agriculture.

Native wildflowers were surprisingly resilient during California’s most recent drought, even more so than exotic grasses. But signs of their resilience were not evident with showy blooms aboveground. Rather, they were found mostly underground, hidden in the seed bank, according to a study from the University of California, Davis.

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.

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?

The ocean is changing around the world—less oxygen, warmer water, higher acidity. The ability to quantify and observe those changes has never been more important, says Maia Hoeberechts, a scientist with the University of Victoria’s world-leading Ocean Networks Canada (ONC).

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.
