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.
In the coming weeks, Parks Australia will release a 2mm wasp on Christmas Island to control the island's yellow crazy ant infestation.
Keeping non-native reptiles as pets is against the law – with good reason. Alien species traded on the black market can potentially establish themselves in the wild if they are released or escape.
Non-native lobsters released into European seas carry diseases and parasites that threaten local species.

Invasive species and diseases pose a major threat to agriculture – particularly in the countries that can least afford it.
At least 100,000 insects are among the many Australian species still to be formally identified. That's a problem for any biosecurity experts who need to be able to spot potentially invasive bugs.
A 'Biblical swarm' of 'super-moths' from continental Europe is heading to the UK.
