The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.
The world’s frogs, salamanders, newts and other amphibians remain in serious trouble. A new global assessment has found that 41% of amphibian species that scientists have studied are threatened ...
About 10% of the species of the Earth can be found in Colombia, including over 1,900 species of bird, more than in Europe and North America combined, Colombia has 10% of the world's mammals species, 14% of the amphibian species and 18% of the bird species of the world. [100]
According to the IUCN, out of all species assessed, over 42,100 are at risk of extinction and should be under conservation. [1] Of these, 25% are mammals, 14% are birds, and 40% are amphibians. [1] However, because not all species have been assessed, these numbers could be even higher.
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.
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 ...
Habitat modification or destruction is one of the most dramatic issues affecting amphibian species worldwide. As amphibians generally need aquatic and terrestrial habitats to survive, threats to either habitat can affect populations. Hence, amphibians may be more vulnerable to habitat modification than organisms that only require one habitat type.
Amphibian Species of the World 6.2: An Online Reference (ASW) is a herpetology database. It lists the names of frogs, salamanders and other amphibians , which scientists first described each species and what year, and the animal's known range.
