Enormous cane toads in Australia are not new – but we might see even larger ones as predators figure out how to eat these introduced toxic toads.
The pet trade has spurred a wave of bird imports, leading to escapes or even deliberate releases of exotic species into the wild. New research reveals the threat they now pose to native birds.
Carp can make riverbeds look like golf balls – denuded and dimpled, devoid of any habitat. Releasing carp herpes virus is a controversial proposition, so let’s weigh up the risks and benefits.
The ways eastern fence lizards have changed in response to red imported fire ants demonstrate how species can adapt to survive the presence of invasive predators.
Rats are disrupting the flow of nutrients towards the sea on many tropical islands – this has consequences for fish behaviour and the wider ecosystem.
Creating and preserving diverse forests can help us prepare for the next insect outbreak and protect our trees.
Scientists have found more ‘alien species’ today in regions that were once key parts of European empires.
38 mammals have been driven to extinction since colonisation, and many more are close to joining them. We have the solutions at hand, but warnings continue to be met with mediocre responses.
Ballast water release from ocean vessels has been a major source of invasive species in the Great Lakes for over 60 years.
New research has found that since the mid-1980s, the economic impact of invasive reptiles and amphibians totals more than US$17 billion.
While official data is yet to be released, this year’s Mediterranean marine heatwave will likely have devastating ecological consequences.
The spread of this urban malaria vector species threatens the gains made against malaria and the achievement of malaria elimination.
Indonesia’s foot-and-mouth outbreak shouldn’t come as a surprise. It’s been decades in the making – just the latest consequence of biosecurity shortcomings in the region.
Wetlands can help limit the spread of the voracious round goby, an invasive species that has infiltrated the Great Lakes and has become widespread in the St. Lawrence River.
Zebra and quagga mussels entered the Great Lakes in large ships’ ballast water. Now, local boaters and anglers are spreading them into the southern and western US.
The simulation showed catching cane toads once a week involved 85% less cost and effort than other strategies, but was just as effective.
Trees were already known for cooling and cleaning the air of cities. A Europe-wide, participative science project shows how much their density matters for urban biodiversity.
Once hated, native predators are now credited with limiting invasive prey populations.
A changing climate will make it difficult to anticipate and prevent invasions.
Correctly identifying species is essential for effective management and conservation.
