[1] [2] This amphibian was put on the IUCN Red List of Endangered Species in 2008 with populations still decreasing. It was reclassified to Vulnerable in 2022.
The eastern newt (Notophthalmus viridescens) is a common newt of eastern North America.It frequents small lakes, ponds, and streams or nearby wet forests. The eastern newt produces tetrodotoxin, which makes the species unpalatable to predatory fish and crayfish. [3]
Although some species, such as the rough-skinned newt (Taricha granulosa) and Eastern newt (Notophthalmus viridescens) in North America or the smooth newt (Lissotriton vulgaris) in Europe, are still relatively common, populations of newts throughout their distribution range suffer from habitat loss, fragmentation, and pollution. This affects ...
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
The other two species are in fact threatened, with P. nebulosus considered vulnerable to extinction and P. poireti classified as an endangered species. [2] The numbers of all three species are declining in the wild. Livestock agriculture is an ongoing major cause of habitat loss and degradation, and of water pollution, for all three species.
Four species are categorized as endangered by the International Union for Conservation of Nature: the Barton Springs salamander, the Texas blind salamander, the black-spotted newt, and the Houston toad. Furthermore, Texas law protects several native amphibians, designating eleven species as threatened within the state and four others as endangered.
The smooth newt, European newt, northern smooth newt or common newt (Lissotriton vulgaris) is a species of newt. It is widespread in Europe and parts of Asia, and has been introduced into Australia. Individuals are brown with a spotted underside that ranges in colour from orange to white.
Palmate newt populations are not in decline overall, and the species has been assessed as Least Concern by the IUCN. [1] In France, it is the most common newt species, [10] but it is rare in Belgium and the Netherlands, [4]: 225 and populations are fragmented on the Iberian peninsula. [1] It is included in some national and regional red lists. [1]
