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.

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.
