The fynbos vegetation that historically clothed the slopes of Table Mountain is highly inflammable. This has been worsened by the spread of alien trees that burn more intensely than the fynbos.
Technology that can identify stray bits of genetic material in the environment can help scientists monitor human and animal health.
Yellow crazy ants are one of the world's worst invasive species. And it turns out they have unique systems of reproduction that make life in the queendom more complicated than we realised.
Invasive species have been invading foreign territories for centuries. By quantifying the mammoth economic impacts, we hope political leaders will start to take notice.
Plus a new technique to protect birds from predators – using fake smells. Listen to episode 10 of The Conversation Weekly podcast.
Most South African provinces are favourable for the establishment of a new invasive alien pest, which may lead to the extinction of native cycad species.
Animals that are traded as pets are more likely to be invasive species, including a relatively new pet: ants.
The Mediterranean region, with its biodiversity, climate, demographics, and economic activities such as tourism, agriculture and fisheries, is particularly vulnerable to environmental risks.
Let's embrace the possibilities of hybrid ecosystems.
Squirrel feeders laced with contraceptives could be used to suppress grey squirrels in the UK.
The spread of tawny crazy ants may be driven, in part, by their need for calcium. The calcium-rich limestone bedrock of the lower U.S. Midwest may provide ideal conditions for populations to explode.
As invasive species transform the world, frontline agencies take solace that species needing unique partners can’t invade alone. A new study on figs shows they may find new partners to invade anyway.
Tadpoles at the edge of the population are no more vulnerable than those at the centre.
Our study is the first to research the impact of online misinformation on biological invasions.
The Arctic has been a remote place for much of its history. But climate change is bringing global problems and opportunities to its door.
Researchers have come up with a new framework that assigns an invasive species threat score to World Heritage Sites. This will improve how these species monitored and managed.
Over spring and early summer, jacarandas and their purple haze line many Australian streets. But how much do you really know about them?
Millions of miles of fences crisscross the Earth's surface. They divide ecosystems and affect wild species in ways that often are harmful, but are virtually unstudied.
The reality TV show I'm a Celebrity, Get Me Out Of Here is under fire for using non-native insects while filming in the Welsh countryside.
Buffel grass causes just as much damage to native wildlife as feral cats. But with the right control measures, biodiversity can bounce back.
