Accepted ecological theory says that poor soils limit the productivity of tropical forests, but adding nutrients as fertilizer rarely increases tree growth, suggesting that productivity is not limited by nutrients after all.

A new study shows that, during the Ice Age, both the East Asian summer monsoon and desertification in Eurasia were driven by fluctuating Northern Hemisphere ice volume and global sea level. 

For many ecologists, fieldwork involves majestic mountains or rushing rivers or large tracts of wilderness. At the very least, it means exploring natural areas that aren’t defined by human development.

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.
