Under the threat of imminent extinction of an entire class of vertebrates is the planet's inhabitants — reptiles or amphibians. Mortal danger to them caused by climate change, pollution, and dangerous fungal infection.
According to researchers from all existing types namely amphibians are the greatest danger — so that within a few decades, toads and frogs, newts and salamanders can simply disappear. According to the International Union for Conservation of Nature, the extinction of 30% of threatened amphibians. Of the 6285 species of amphibians, caught in the Red Book of the organization, are under threat of death 1895. With 39 of them have disappeared altogether or only in the wild, 484 are critically endangered, and 754 — just endangered and 657 are vulnerable.
Scientists believe that in the future the situation may become worse. "In the coming decades, we will see a significant reduction in the number of amphibians — says the director of the Center of microbiology, evolution and climate change at Copenhagen University Professor Carsten Rabek. — The fact that amphibians have nowhere to run and nowhere to hide, because human civilization bulldozer destroys the environment of their habitat.
An international team from Frankfurt, Madrid and Yale led Rabeka studied 5527 species of amphibians around the world. As a result, it was concluded that the most dangerous regions are Africa, America, Asia and Europe. There, these primitive vertebrates threatened by climate change, habitat loss and deadly fungal infection Chytridiomycota. This fungus has spread among the African clawed frogs, which are imported in large quantities for the European research laboratory.
Particularly affected amphibian populations in areas with a higher level of biological diversity. According to scientists, the extinction of amphibians, which play an important role in the biological equilibrium of the planet in this century is significantly faster due to a combination of all three negative factors, the ITAR-TASS news agency.
