Introduced species and diseases can drive native species into smaller environmental niches – and that could mean change to how we work to conserve them.
For invasive species leaving their home, they leave not only their predators but also the species that helped them thrive.
Scientists use genetics and historical records to reveal how the species pulled off one of the most infamous biological invasions of all time.
New research finds 74 per cent of land managers who reported releasing a powerful biocontrol, release it during the peak rabbit breeding period. This can lead to rabbit populations actually increasing.
Human-made debris such as plastic have vastly increased the numbers of marine species crossing the oceans, write Emma Johnston and Jim Carlton.
It will not be simple or cheap, but fencing dams in arid areas could create "cane toad breaks" to halt the march of these invaders across the continent, writes Mike Letnic
Erecting fences to stop cane toads entering man-made dams to cool down in hot, dry parts of Australia is an effective way to stop their spread, UNSW-led research shows.
Weeds in the UK are still evolving hundreds of years after their introduction and are unlikely to have reached their full potential as invaders, UNSW scientists have discovered.
