A sweeping new study of 1,758 butterfly species across 105 countries found many tropical species are expanding their ranges, while temperate ones are contracting—with climate change a major driver.

Genetic analysis of bison dating back 20,000 years shows how the 19th-century slaughter reshaped the species—and how today's herds could recover.

A new study finds that burying logging debris, instead of burning it, could store far more carbon and generate billions in revenue for forest-thinning projects.

In a new study, people who listened to audio recordings of birds singing report getting less benefit when paired with even quiet traffic sounds.

Past studies of coral probiotics stayed in the lab. This one tested them on wild coral in the Red Sea during an actual marine heatwave—and the microbes held up.

A new analysis shows that cavities inside trees can run several degrees cooler than the surrounding air during heatwaves—a finding that reframes the role of forests in a warming world.

A new study finds that stopping logging and wildfires could do more for rainforest wildlife than halting deforestation—and it costs far less than restoration.

Hobbled by a lack of data, scientists have been unable to track biodiversity across much of the planet. A new initiative called Amazon.ia shows how technology might help solve the problem.

A study in Washington State found about nine times as many coyotes per area in Seattle as in remote forests.

Sounds of a healthy reef coaxed coral larvae to settle on artificial structures in Hawai'i—a possible start to “hybrid” reefs, part natural, part built.
