Critically endangered (CR) species face an extremely high risk of extinction in the wild. As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct. [1] [2] 9.2% of all evaluated amphibian species are listed as critically ...
Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. As of September 2021, the International Union for Conservation of Nature (IUCN) lists 1085 endangered amphibian species. [1] Of all evaluated amphibian species, 14% are listed as endangered. No subpopulations of amphibians have been evaluated by the ...
However, many amphibian declines or extinctions have occurred in pristine habitats where the above effects are not likely to occur. The causes of these declines are complex, but many can be attributed to emerging diseases, climate change, increased ultraviolet-B radiation, or long-distance transmission of chemical contaminants by wind.
According to the International Union for Conservation of Nature (IUCN), 93 reptile and amphibian species in the United States are threatened with extinction. [1] The IUCN has classified each of these species into one of three conservation statuses: vulnerable VU, endangered EN, and critically endangered CR.
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature.
See: List of endangered amphibians, List of critically endangered amphibians. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN. Additionally 1567 amphibian species (24% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full
Climate change is worsening the planet's biodiversity crises, making environments more deadly for thousands of species and accelerating the precipitous decline in the number of plants and animals ...
The population of the mountain chicken frog, once abundant in the Caribbean, has dropped by over 99% in 20 years due to a deadly fungal disease.
