Unless the clearing of tropical forests is halted, the mean global temperature could rise an extra 0.8 °C, even with cuts in emissions from fossil fuels, scientists warn in an article in Nature Communications

New research from Florida Institute of Technology finds that fish born in marine reserves where fishing is prohibited grow to be larger, healthier and more successful at reproduction.

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.

The simple story says that during the last ice age, temperatures were colder and ice sheets expanded around the planet. That may hold true for most of Europe and North America, but new research from the University of Washington tells a different story in the high-altitude, desert climates of Mongolia.

For nearly two decades, scientists have noted dramatic changes in arctic tundra habitat. Ankle-high grasses and sedges have given way to a sea of woody shrubs growing to waist- or neck-deep heights. This shrubification of the tundra challenges animals like caribou that are adapted to low-stature arctic vegetation.

Warm, wet summers are historically unusual and could bring unexpected disruptions to ecosystems and society, according to new research from the University of British Columbia.

Spring is arriving earlier, but how much earlier? The answer depends on where on Earth you find yourself, according to a study led by the University of California, Davis.

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.
