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.

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.
