In the frigid seas halfway between mainland Norway and the North Pole, two types of animals browse the palatable vegetation of a high-tundra archipelago, munching on thick moss, cropped grasses and low-lying shrubs. 

Using laser scanning, researchers at the University of Helsinki have mapped out how the fragmentation of forests affects tree shape in the rainforests of Brazil.

A 20-year experiment in the Sierra Nevada confirms that different forest management techniques — prescribed burning, restoration thinning or a combination of both — are effective at reducing the risk of catastrophic wildfire in California.

Likening it to providing more runways at busy airports, researchers at North Carolina State University found in a new study that adding protruding rocks to restored streams can help attract female aquatic insects that lay their eggs on the rock bottoms or sides.

In its latest accounting, the International Union for Conservation of Nature finds that more than 44,000 species worldwide are threatened with extinction.

Fluctuating sunlight poses a challenge for plants and green algae, which must quickly adjust their photosynthetic systems to remain efficient in changing conditions.

Ocean acidification, mammal respiration, and aerosol formation all depend on chemistry that occurs at air-water interfaces.

Record breaking marine heatwaves will cause devastating mass coral bleaching worldwide in the next few years, according to a University of Queensland coral reef scientist.

Tropical coral reefs are among our most spectacular ecosystems, yet a rapidly warming planet threatens the future survival of many reefs.
