Dozens of deep-sea corals thrive off the California coast, but many are still unknown to science.

Accurately predicting whether, and when, a species may go extinct has never been more critical.

A new study shows that invasive species can have a dramatic impact on native species — and that a strong proactive response can help mitigate those impacts.

Hummingbirds are so fast they’re often not seen, only heard.

It might seem counterintuitive, but if cities and towns were properly designed, they could help species face the threat posed by climate change.

About 10,000 years ago, giant beavers roamed the North American continent, along with now-extinct woolly mammoths and mastodons.

This week USGS scientists, with support from the New York State Department of Environmental Conservation, installed technologically advanced monitoring systems to study water-quality conditions and harmful algal blooms—known as HABs—in Owasco and Seneca lakes.

Wild pigs—a mix of wild boar and domestic swine—are spreading rapidly across Canada, threatening native species such as nesting birds, deer, agricultural crops, and farm livestock, research by the University of Saskatchewan (USask) shows.

Kate Field, a graduate student at the University of Victoria, has identified an opportunity for improved treatment of animals studied in the wild.

Hunting is a major threat to wildlife in tropical regions.
