Carnivorous bullfrog tadpoles don’t even spare their own.
A new study reveals that it’s not only adult bullfrogs that pose a threat but their tadpoles do, too.
Argentine ants are a fact of life in many parts of Australia, but can still potentially be banished from Norfolk Island.
Invasive pest ants cause billions of dollars worth of damage to crops, and threaten some of Australia's World Heritage rainforests. The federal budget has pledged nearly $30m on wiping them out – but how?
Phragmites, an invasive species, line this marsh at Sachuest Point in Middletown, Rhode island.
Phragmites australis, an invasive reed, has taken over wetlands across the US. But it also stabilizes shorelines and harbors many fish and birds. Is it time to compromise with this alien?
The Mossy Red-eyed Frog is among hundreds of species threatened with extinction at the hands of chytrid fungus.

Chytrid fungus has caused declines in 501 amphibian species, according to a new analysis. Most of the damage happened in the 1980s, before the fungus itself was even discovered.
Fire ant stings can be deadly to people who have an allergic reaction to their venom.

Invasive tropical fire ants spread by eating their fat useless sons.
Fire has burned through a swathe of the Tjoritja National Park.
Tasmania wasn't the only part of Australia that burned in January. The remote interior near Alice Springs saw a huge blaze, worsened by invasive buffel grass.
There are 130 billion gallons of water in Wisconsin’s Lake Mendota, and now, trillions of spiny water fleas.
It's cheaper to prevent biological invasions than to react after they happen. But it's hard to detect invaders while there are still just a few of them. Knowing when and where to look can help.

Populations of freshwater species are in a state of deep decline. But we know why and we can reverse the trend.
In the firing line.
We need to learn to coexist with wildfires the way many ecosystems do. We won't protect lives in the long term by trying to stamp the fires out.
Not welcome: the African big headed ant might be small but it can be a pest if it gets in your home.
The ants were a threat to many native species on Lord Howe Island. They were also a pest if they got into your home.
Cane toads are on the march, but new genetic research could slow them down.
New genetic knowledge about cane toads could give us the knowledge we need to throw some more roadblocks in front of this persistent invader as it marches across Australia.
Controlling rabbit populations has a key role in conserving Australia’s native plants and animals
Managing rabbit populations isn't as simple as declaring 'open season'.
New findings from the Chagos Islands are a perfect parable for the Anthropocene.

Feral rabbits previously exposed to myxoma virus are more likely to be killed by rabbit haemorrhagic diease, meaning that these two biocontrol agents can become even more powerful when used in tandem.
A feral cat snapped by a remote camera in the wild.
The average Australian feral cat kills 225 reptiles a year, which adds up to 596 million in total, according to a new estimate. Pet cats, meanwhile, kill a further 53 million.
New study confirms fears that the island's native wildlife can be poisoned by introduced Asian toads.

Diversibipalium multilineatum. This species can reach 40 centimeters (16 inches) in length.
Several giant terrestrial Plathelminth species have invaded France and its overseas territories, threatening biodiversity. Thanks to participatory science, the invasion is finally recognized.
Research suggests there is no “safe number” of brumbies that will avoid harm to mountain ecosystems.
Failing to cull feral horses in Kosciuszko National Park may end up promoting environmental destruction while actually increasing the horses' suffering.
Gould’s goanna is commonly eaten in Indigenous communities, but can contain high levels of rat poison.

Rat baits are widely used to keep rodent pests at bay. But many Australian reptiles are resistant to the poison, potentially spreading these deadly compounds up the food chain.
