The world missed all 20 targets for stemming the tide of biodiversity loss. But there has been some progress over the last decade.

All the adult Asian longhorned ticks found in the United States so far have been female. Here's why.

Our research investigated 900 'alien' species across almost 200,000 protected areas worldwide.

Mud blister worms make their homes in the shells of oysters and other shellfish, where they weaken their hosts.

Are 'murder hornets' from Asia invading North America? A Japanese entomologist who's been stung by one and lived to tell the tale explains what's true about these predatory insects.

Asian giant hornets have arrived in a small portion of the United States. "We do not know how the species arrived in the United States but it is important to not overreact."

The decline of quokkas in Australia has been somewhat of a mystery, but resarcehers have a suspect. Invasive species, and foxes in particular.

Coffee rust is a huge problem, but an invasive snail seems to eat its spores off leaves. Scientists say it's a potential strategy, but isn't without risks.

New strategies for controlling invasive species, including quagga and zebra mussels, aren't toxic and take local ecosystems into consideration.

Scientists often don't know which nonnative insect will emerge as the next harmful invader. A new strategy uses evolutionary history to find out.
