California red-legged frogs are threatened with extinction.
Amphibians have been devastated by a chytrid fungus pandemic. Researchers immunized California red-legged frogs in Yosemite to give them a fighting chance at survival, with surprising results.

Melanesia’s tropical islands are home to at least 700 species of frogs – many with tiny ranges. We must safeguard these biological treasures.
Populations of Fleay’s barred frog in Australia’s ancient rainforests were decimated by the chytrid fungus. Now, the frogs have developed a natural resistance.

Thousands of sick and dead frogs are turning up around Australia, bizarrely lying out in the open. If you see one, let these scientists know.
The rapid rate of species declines means we should trial potential solutions before it’s too late.

We’ve identified three frog species very likely to already be extinct. Another four species on our list are still surviving, but not likely to make it to 2040 without help.

It’s typically rare to see a dead frog. Yet, we’ve received a flurry of emails from people coming across them in this truly unusual, and tragic, mass death event.

The Bsal fungus is not yet here in North America, or any place in the Western Hemisphere, but there is concern that the pet trade is the most likely route for introduction here.
The horned land frog (
Sphenophryne cornuta) carries babies on its back. New Guinea must be protected from the deadly chytrid fungus, or we could see around 100 frog species be wiped out.
The island of New Guinea is home to 6% of the world’s frogs, but if the deadly chytrid fungus invades it could cause a mass extinction.
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.

How do you pack butterflies for shipping, or frogs for an overland hike to a new habitat? Three scientists explain how they keep threatened species safe on the road and in the air.
Some tropical frogs may be developing resistance to a fungus that has devastated species like
Atelopus varius, the variable harlequin frog.
A look at new research published in 2018 on fossa, deepsea corals and tropical frogs developing resistance to a deadly fungus.
Panamanian golden frogs (
Atelopus zeteki) are listed as critically endangered, and may be extinct in the wild.
Chytrid fungus has caused a global “amphibian apocalypse,” killing frogs worldwide. Now some appear to be evolving resistance – but a closely related fungus threatens newts and salamanders.

Frogs and toads are declining around the world, with many species on the brink of extinction. Acting in time means trying strategies without complete information about how likely they are to work.
The Northern Corroboree frog is among seven species at grave risk from fungal disease.
Chytrid fungus has already wiped out six species of Australian frogs since the disease arrived in the 1970s. Without urgent action, seven more are facing extinction.
Frog chytrid may have been spread by humans. It is a fungus that has decimated amphibian species.
As much as animals may pass on viruses to humans, humans pass on viruses which are sometimes lethal to the animal world as well.

The chytrid fungal disease that has ravaged amphibians worldwide has reached Madagascar. But it’s possible this could be a blessing in disguise.

South-west of the port of Gladstone in Queensland lies Kroombit Tops National Park, housing many plants and animals, some of them unique. The reserve includes steep escarpments with wet, rainforest gullies…
There are fewer than 50 Southern Corroboree Frogs in the wild.
High up in the sub-alpine bogs of the Snowy Mountains lives one of Australia’s most iconic and rarest creatures, the Southern Corroboree Frog (Pseudophryne corroboree). This small, vividly-coloured species…
