Pot disease led to the extinction of 90 species of amphibians.

The Panama Forest was once a paradise for amphibians.
one night, dozens of frogs chorus in unison, quite a trace of "rice flower fragrance said rich years, listen to the sound of frogs a piece of" poetic.
However, in just a few years, everything has changed.
amphibian choruses are getting weaker, forests are becoming quieter, and many amphibian species are beginning to disappear.
an international team led by the Australian National University (ANU) has found that a fungal disease, pot disease, has led to a sharp decline in the population of more than 500 amphibians over the past 50 years, 90 of which have become extinct, ScienceDaily reported.
amphibians can live in both water and land, consisting mainly of frogs, dragonflies and dragonflies.
so, where did the mass extinction of amphibians come from? Pot disease is also "what evil"? Do we have a way to reverse the momentum of amphibian extinction? The story of the rapid decline and extinction of amphibians began around the 1970s. "There is a lot of evidence that amphibians have experienced a global population decline and species extinction since the 1970s, with rapid decline and a wide range of threatened species, ranking first among terrestrial vertebrate groups," Dr. Liu Xuan, an associate researcher at the Institute of Zoology at the Chinese Academy of Sciences in
, told Science daily.
scholars regard the rapid decline of amphibians as an iconic event in the sixth mass extinction in Earth's history.
, Liu Explained, but it's strange that for a long time, scientists couldn't find the cause of the rapid decline of amphibians.
the decline of amphibians was once called a "mysterious decline" because many amphibians have suddenly disappeared in remote mountainous areas or nature reserves far from human interference, and some of the mainstream hypotheses explaining endangered wildlife, such as habitat loss, human killing, and climate change, do not explain the large number of amphibian declines.
the terrible pot bacteria completely destroyed them in 1989, at the first World Amphibian Reptile Conference at the University of Kent in the United Kingdom, the global decline in amphibians began to attract the attention of experts.
scientists are beginning to look for what caused the amphibians to die out.
, it wasn't until the late 1990s that a team led by Dr. Lee Berger of James Cook University in Australia discovered a deadly fungus, pot bacteria, from the skin surfaces of a large number of dead and sick frogs in the mountains of south-eastern Australia, south-central Costa Rica and the Fortuna Forest Reserve in western Panama, opening a new window into the mystery of the decline of amphibians, according to Liu Xuan. After
, the disease was reported in South America, North America, Central America, Europe, Africa and Asia, and was speculated to be closely related to the decline in amphibians; After
, scientists discovered that pot bacteria are found to have different toxic strains in different parts of the world.
since then, the pot bacteria disease this "evil is out of the original." Writing in the journal Science, Dr Ben Shearer, of the Fenner School of Environment and Society at the Australian National University, who was involved in the new study, said: "Pot disease is a disease that infects amphibians caused by pot bacteria fungus.

the fungus is active in humid environments such as streams and rainforests.
pot disease, a skin-borne disease, has completely destroyed some species and led to the sporadic deaths of many more species.
" Liu Xuan explained that the main fatal mechanism of pot bacteria disease is that the electrolyte exchange function of the skin of diseased frogs can be reduced to less than 50% of normal levels, while the concentration of blood potassium and sodium in the diseased frogs has decreased significantly, the imbalance of sodium potassium metabolism will further affect blood vessel dilation and contraction, so that the blood flow slows down and blood circulation disorders, leading to serious cardiac arrest in frogs.
, scientists have found cases of pot disease in more than 60 countries, with the worst affected areas being Australia, Central and South America.
unprecedented decline in amphibian species has made the pot fungus one of the world's most destructive invasive species. Dr
Scherer said: "The highly deadly wildlife disease of potbacteria is contributing to the sixth mass extinction on Earth.
this disease led to the mass extinction of amphibians around the world, we have lost some very amazing species.
for example, over the past 30 years, more than 40 frogs in Australia have declined as a result of the fungal disease, seven of which have gone extinct.
the team's research shows that many species are still at very high risk of extinction due to the continued decline in numbers over the next 10 to 20 years. "The globalist wildlife trade is the main cause of the spread of pot disease around the world," Dr.
globalisation or "the culprit" Explains in the journal Science.
, humans are increasingly moving plants and animals around the globe, introducing pathogens into new regions.
" Liu Xuan told reporters that alien amphibian invasion and climate change are important causes of the rapid spread of amphibian pot disease and widespread outbreaks.
bullfrog as a global invasive species, where it can transmit the pot bacteria it carries to local amphibians.
at the same time, climate change could alter habitats that were not intended for pot bacteria, thus contributing to outbreaks of pot disease.
it is understood that Liu Xuan and his colleagues have done a comprehensive study on a global scale, found that the international trade in live animals, alien amphibian invasion and climate suitability are all playing an important independent role in explaining the global pot bacteria invasion pattern, this conclusion has been confirmed in regional studies in different countries around the world. "It's very difficult to remove pot bacteria from an ecosystem - if it's in an ecosystem, unfortunately, it's there,"
Schaeler said.
partly because some species that have not been killed by the disease are resistant to pot fungus, which means that they carry the fungus and act as a reservoir for it, so there is a constant flow of fungi in the environment.
", "A multi-pronged effort to slow the extinction of species, what can we do to slow the rate of amphibian extinction caused by pot bacteria?" Shearer said there was an urgent need to improve biosecurity and wildlife trade controls to prevent more amphibian extinctions around the world. "There is no effective way to cure or alleviate amphibian pot disease, " said Liu Xuan,
.
therefore, on the one hand, there is a need for more stringent supervision of the introduction of international trade in live amphibians and invasive amphibians to reduce the spread and spread of lethal pot bacteria strains around the globe, while strengthening field monitoring of declining amphibian populations and actively trying and developing new technical means to carry out research on pot bacteria disease treatment methods. "Knowing which species are at risk can help develop future research plans to develop conservation actions to prevent extinction, " said
."
" in traditional Chinese culture, frogs symbolize the vitality of nature, symbolizing the leisure and lightness of people's lives: "Yellow mei when the family rain, grass pond everywhere frog."
"Looks forward to the government, scientists and all parties working together to make "Listen to the Frogs" no longer a sound, not only to restore the richness and diversity of the ecosystem, but also to make people more poetic.
