Decline in amphibian populations. The golden toad of Monteverde, Costa Rica, was among the first casualties of amphibian declines. Formerly abundant, it was last seen in 1989. Since the 1980s, decreases in amphibian populations, including population decline and localized mass extinctions, have been observed in locations all over the world.
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.
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 ...
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. No subpopulations of amphibians have been evaluated by the IUCN.
Habitat loss is perhaps the greatest threat to organisms and biodiversity. [40] Temple (1986) found that 82% of endangered bird species were significantly threatened by habitat loss. Most amphibian species are also threatened by native habitat loss, [41] and some species are now only breeding in modified habitat. [42]
Since the 1950s, the population has declined rapidly due to habitat destruction and overhunting. It has been listed as Critically Endangered in the Chinese Red Book of Amphibians and Reptiles. Despite the Chinese Government listing the salamander as a Class II Protected Species, 100 salamanders are hunted illegally every year in the Hupingshan ...
Karpathos frog. The Karpathos frog (Pelophylax cerigensis) is a species of frog in the family Ranidae. It is endemic to the island of Karpathos, South Aegean Sea, Greece. The Karpathos frog is considered the most endangered anuran amphibian in Europe because its range is restricted to two small rivers in the north part of the island.
The bleeding toad, fire toad or Indonesian tree toad (Leptophryne cruentata) is a species of true toad in the amphibian family Bufonidae, endemic to Java, Indonesia. [1] [2] L. javanica was, formerly, synonymous with the bleeding toad prior to its description as a distinct species in 2018, [1] although the degree of differentiation between these species is low.
