Fungi that kill amphibians depend on the greatest losses from nature from one disease, according to researchers.
Better biosecurity and the boundaries of wildlife trade are vital so that people are no longer extinct, they say.
The disease, chytridiomycosis, has suffered huge deaths for frogs, toads and salamanders over the past 50 years, including a total of 90 species, according to a review of evidence.
It has spread to over 60 countries.
Australia, Central America and South America are particularly difficult.
"Wildlife disease is very impressive, including cyttridiomycosis, contributing to the sixth major devastation in the Earth," said Dr Ben Scheele of the National University of Australia in Canberra.
"We've lost some really amazing species." T
Three years ago, scientists started to notice that amphibians were dying around the world. The suspect was identified as a fungus known as the fungus Batrachochytrium dendrobatidis (Bd), which attacks the amphibian skin, effectively "eating" them alive.
A major revision of the evidence published in the Science magazine appears:
- The fungus has produced at least 501 deaths of amphibians (6.5% of known species). T
- 90 have been consolidated or removed at the wild, while other species have fallen by over 90% t
- In many species fungi are the major cause of amphibian death, but others collaborate with habitat loss, climate change and extinction from invasive species to drive species to plantations. below.

The scientists say that globalization and wildlife trade are the main causes of this pandemic and they give the disease an opportunity to spread.
“People are moving plants and animals around the world at an ever-growing level, including patches in new areas," said Dr Scheele.
According to two Canadian experts, the fungus is "one other note in the chest for a worldwide amphibian world".
Loss of habitat, use and climate change are the main threat to thousands of species, according to Dan Greenberg and Wendy Palen from Simon Fraser University in Burnaby, Canada.
“These risks often work together, but there are clear regulatory actions to address at least some: protecting habitat, preventing wild populations, and preventing trade," they wrote in an article an introduction to the new Science research.
