Amphibious 3.5 million years to walk around the earth, many species face extinction, which is a new trend in federal government national surveys of wildlife habitats.
Federal wildlife scientists on Wednesday reported that frogs, salamanders and toads died of a surprising fast nation decline in the number of the most serious endangered species
The Monitoring Initiative group approved by the amphibian research parliament has compiled hundreds of studies in the past decade to reduce amphibians. Research published in one journal PLOS has been discovered through research conducted by Michael Adams, US Geological Survey and is also being studied in the research, by protecting the national park of the island, amphibians are on the verge of extinction To do.
"This analysis shows that the reduction of amphibians can be widespread and more serious than previously recognized," the study concludes. It turned out that half of the habitat occupied the country, meaning they disappear in 26 years, the total number of relatives and frogs fell by 7% per year. For 12 kinds of threatened species, the situation gets worse, the number decreases by 11.6% per year
The report points out that nearly one-third of amphibians are extinct crisis globally. The destruction and propagation of the habitat of fungal syndrome is considered to be a major cause
"Amphibians do a lot of important work," said the US Geological Survey released a statement to the investigation. "They control pests, provide medicines, supply other animals, and help to play a role in the ecosystem.They are special, diverse, beautiful animals, they are art and culture They have inspired social values, they are the oldest sources of biodiversity, we have amphibian fossil records dating back about 3.5 million years ago. "
Klaus Colbert cited a recently published book and sketched out extinction of several awesome planets currently being done. Amphibians are the most threatening creatures to the extinction level 45,000 times background rate. They are not alone. One third, one third of fresh water molluscs, all sharks and light rays coral reef construction one-third of corals, all mammal quarters, all birds, and all fifth of all reptiles I will forget about a sixth. Finally, Klaus pointed out its climate change and played an important role in the extinction of the whole human evolution. Because all modern people's ancestors are now located in the southern Africa population has been decreasing to about 500 people, the development of early human family and culture has been greatly affected by climate change. Marean studied the key group
According to the Smithsonian Institute and the World Wildlife Fund, wildlife populations have declined by 52% at an alarming rate since 1970. It is mainly focused on mammals, birds, amphibians and reptiles. This reduction is due to several reasons, such as overdevelopment, loss of habitat, pollution and climate change. Higher hunting of white rhinoceros in South Africa has become a seed for the reintroduction of the land and promote the legalization of private landowners, Nigel Leader Williams and others published in 2005 "International Wildlife Conservation Law and Policy Journal" I said. As a result, it increased from less than 100 white rhinoceroses to 11,000. Leader Williams' research also showed that the Zimbabwe trophy hunting is relative to the wildlife area to the civil protected area doubling
