Declines in amphibian populations were first widely recognized in the late 1980s [citation needed], when a large gathering of herpetologists reported noticing declines in populations in amphibians across the globe. [6] Among these species, the Golden toad (Bufo periglenes) endemic to Monteverde, Costa Rica, featured prominently.
The average size of global wildlife populations have declined by 73% in 50 years, a new study by the World Wildlife Fund has found.. The study, titled the 2024 Living Planet Report, monitored ...
A 2022 study estimated that while right now, 14.8% of the global range of all anurans (frogs) is in an extinction risk area, this will increase to 30.7% by 2100 under Shared Socioeconomic Pathway SSP1-2.6 (low emission pathway), 49.9% under SSP2-4.5, 59.4% under SSP3-7.0 and 64.4% under the highest-emitting SSP5-8.5.
Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
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.
Note the wing tagsused for population monitoring. An endangered speciesis a speciesthat is very likely to become extinctin the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change.[1]
We find that amphibians are the most threatened vertebrate class (40.7% of species are globally threatened). The updated Red List Index shows that the status of amphibians is deteriorating globally, particularly for salamanders and in the Neotropics. Disease and habitat loss drove 91% of status deteriorations between 1980 and 2004.
Additionally 1193 amphibian species (16% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 2 ]
