Amphibians are facing an extinction crisis, but getting to the facts has been difficult. Threatened Amphibians of the World is a visual journey through the first-ever comprehensive assessment of the conservation status of the world's 6,000 known species of frogs, toads, salamanders, and caecilians...

根据划线词后文Scientists have found,surprisingly,that if they set out to protect places where threatened birds,mammals and amphibians (两栖动物) live together,they'll meanwhile protect many more threatened reptiles. (令人惊讶的是,科学家们发现,如果他们开始保护受威胁的鸟类、哺乳动物和两栖动物共同生活...

animals, but this new study held some good news too. Conservation efforts by humans have slowed the loss of many species of amphibians (两栖动物), birds, and mammals. Losses in these groups would have been about 20 percent greater had it not been for recent action of protection. ...
The total number of extinct species has reached 785 and a further 65 are only found in captivity or in cultivation. One in four mammals, one in eight birds, one third of all amphibians and 70% of the world''s assessed plants on the 2007 IUCN Red List are in jeopardy....
That’s a large fraction of Earth’s animals but this new study held some good news too. Conservation efforts by humans have slowed theloss of many species of amphibians (两栖动物) birds and mammals. Losses in these groups wouldhave been about 20 percent greater had it not been for recent...
and amphibians has the status of virtually all known species been assessed. Threatened species are defined using the International Union for Conservation of Nature's (IUCN) classification: endangered (in danger of extinction and unlikely to survive if causal factors continue operating) and vulnerable ...
The Anthropocene is tightly associated with a drastic loss of species worldwide and the disappearance of their key ecosystem functions. The orders Testudines (turtles and tortoises) and Crocodilia (crocodiles, alligators, and gharials) contain numerous t
the drivers of threatened species richness independent of the drivers of the size of the species pool, we account for the role of total species richness within our models. We then assess the influence of the covariates on four taxonomic groups individually (amphibians, reptiles, birds and mammals...
