New research conducted by experts around the world has found that the number of amphibian species threatened with extinction around the world has risen to 41% as the effects of global warming increase.
Foreign news agencies reported that experts issued new results from a study conducted on 8,011 amphibian species published in the journal Nature, and found that 41% of them are at risk of extinction. This is an increase from preliminary research conducted in 2004, which estimated the percentage at 39% of all species.
Human activity and climate change affect the Earth’s balance. Cause harm to local fauna and flora. Amphibians are the worst among vertebrates. It is estimated that mammals are at risk of extinction by 27% of all species, reptiles by 21%, and birds by 13%.
The evaluation was carried out by more than 1,000 experts around the world, and the animal is classified as endangered, meaning it is assessed as severely threatened with extinction. Endangered, or vulnerable (vulnerable) on the International Union for Conservation of Nature (IUCN) Red List
“Most of the time. Reserved areas and conservation plans have been designed with the needs of mammals and birds in mind,” said Jennifer Luedtke, a conservationist with the Texas-based nonprofit Re:Wild, and IUCN Red List coordinator. Through the cracks.”
Amphibians appeared on Earth more than 300 million years ago, and so far only 3 orders remain: the order of frogs (order Anura), the order of snakes (order Gymnophyona), and the order of salamanders (order Codata/Urudella) with a ratio of 39%, 16% and 60% exposed. In danger of extinction respectively.
The research team also found that four species of amphibians, including frogs from Australia, toads and salamanders from Guatemala and toads from Costa Rica have disappeared since the 2004 assessment, and another 185 species may become extinct. Where its living inhabitants have not yet been found.
Habitat destruction and degradation, mainly caused by agriculture and livestock, accounts for 93% of the factors affecting all threatened amphibian species. But the impacts of disease and climate change are expanding as a result.
“Amphibians are particularly sensitive to changes in their environment. This is partly because they breathe through their skin,” said Kelsey Nemey, a co-author of the study. “This increases the frequency and intensity of extreme weather events, and changes in humidity, temperature, sea levels and hills.” Loss of important breeding areas may cause increased mortality, habitat degradation and habitat change, making it more difficult for amphibians to find suitable habitat.
The research also found ongoing risks from the animal trade and the hunting of amphibians for food. The highest concentrations of amphibians are found in the Caribbean islands, Mexico, Central America, the tropical Andes, India, Sri Lanka, Cameroon, Nigeria, and Madagascar.
