New research shows that biodiversity is important not just at the traditional scale of short-term plot experiments—in which ecologists monitor the health of a single meadow, forest grove, or pond after manipulating its species counts—but when measured over decades and across regional landscapes as well.

“I spent 15 years removing cats from fenced reserves and national parks,” Katherine Moseby was saying. “And then, all of a sudden, I was putting them back in. It felt very strange to be doing that.”

As abundant and widespread bees, it is common to see both bumble bees and honey bees foraging on the same flower species during the summer, whether in Britain or many other countries.

In the Namib Desert in southwestern Africa, the Kuiseb River, an ephemeral river that is dry most of the year, plays a vital role.

High latitude regions play a key role in the global carbon cycle and climate system.

But a new study from the University of Adelaide, published in Nature Climate Change, shows that the ocean acidification predicted under continuing high CO2 emissions may make cooler, temperate waters less welcoming.

Bark beetle outbreaks and wildfire alone are not a death sentence for Colorado’s beloved forests—but when combined, their toll may become more permanent, new CU Boulder research shows.

For decades, scientists have wrestled with rival theories to explain how interactions between species, like competition, influence biodiversity.

California’s Central Valley and the Colorado River Delta host more than 82 million birds every year during the fall migration, according to a new study published in the journal Ornithological Applications.

Heart disease is a killer threat for southern sea otters feasting on domoic acid in their food web, according to a study led by the University of California, Davis.
