COVID-19 threatens to derail conservation efforts and research for a year, which could be a huge blow to the field. Here, a biologist explains the threat.

Researchers have identified biodiversity hotspots in the high seas, "the planet's last global commons." Will a UN treaty establish international ocean parks?

Plants and animals are remarkably similar in their responses to changing environmental conditions across the globe, a new study finds.

Farms with diverse crops can protect endanged species and biodiversity while also standing up better to the effects of climate change, researchers say.

In a kind of "fatal attraction," small predators drawn to kill sites for leftover scraps may get killed themselves when big predators return for seconds.

"One of the most critical and conspicuous ways that diversity is changing is by changing the distribution of species across space." Bird "census" data indicate the risks.

Roundup, one of the world's most popular weed killers, can make ecosystems more vulnerable to pollution and climate change.

After frogs in protected area of Panama died off en masse, the snakes that ate them began to disappear, too. It shows the extent of our "biodiversity crisis."

Unless global warming declines, extinction is in store for as many as one-third Earth's species of plants and animals worldwide.

A new map that tracks the genetic diversity of freshwater and marine fish offers another tool to protect species around the world.
