Guam’s trees are in trouble, thanks to the accidental release of a snake species 70 years ago, which has killed off many of the bird species that are vital for the health of the island’s forests.
Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.
Swine brucellosis is spreading from Queensland into New South Wales. It’s carried by feral pigs and poses a real risk the people and dogs that hunt them.
Invasive frogs can have a major impact on the environment. Some move continents by human trade or travel. But determining how to control them can lead to policies that limit their spread and effects.
There’s a terrifying species that spreads rapidly, breeds prolifically and eats hundreds of plants. But the first research into the actual harm caused by giant African land snails found … not much.
Regulating species in South Africa is difficult. But identifying those creating the greatest tension, would shift focus on the most destructive species.
Exotic pets may rank highly on the novelty and excitement scale, but little is known about their ownership in Australia.
Developing countries have been slow to react to the alien species problem. Its impact can be massively reduced if policies are developed to deal with the issue.
Most of the earthworms in the US Northeast and upper Midwest are nonnative species. Scientists are finding increasing evidence that invasive worms and invasive plants may help each other.
Many alien plants and animals have been introduced to Africa from other regions and spread from country to country, often having devastating effects.
Africa’s orphan crops are under-researched and underutilised. They can be a vital tool in combating food and nutrition insecurity on the continent.
Before we decide to eradicate or control an invasive species, like carp, we need plenty of scientific evidence and independent assessments first.
Forests are valuable for many uses, including timber, clean water, wildlife habitat and recreation. Stresses on U.S. forests include wildfires, pest invasions and development of private lands.
Super-fertile slugs from the continent have bred with their cousins in the UK.
New research has uncovered a whole new way to combat the devastating crown-of-thorns starfish, by decoding the pheromones that they use to communicate.
A reliable water supply from Australia’s mountain catchments depends on intact and functioning ecosystems.
Grey squirrels have lots of attractive characteristics, yet they are actively persecuted by humankind.
Indigenous biocontrol agents could be used to curb the spread of invasive wasps across South Africa and into sub-Saharan Africa.
Improvements in knowledge and control methods mean eradicating the Australian invasion is challenging, but still potentially feasible.
