Nearly 100 species of amphibians have been destroyed. More than 500 species of amphibians are in decline. Discovered two decades ago, in the chytrid fungus & NBSP;Batrachochytrium dendrobatidis & NBSP;since then it has caused mass deaths worldwide in amphibians.

& NBSP;a large group of scientists published & NBSP; report& NBSP; covering degree& NBSP;B. dendrobatidis& NBSP;. Destruction & NBSP;B. dendrobatidis & NBSP;It causes chytridiomycosis. They are studying a large collection of data from other published studies, widely used databases, as well as other data, amphibian experts gathered.

Amphibian losses from & NBSP;B. dendrobatidis& NBSP; with & # 39 is the largest documented loss of biodiversity by the pathogen. Even compared to the most damaging invasive species, & NBSP;B. dendrobatidis & NBSP;still very devastating. consider& NBSP; Long ubiquitous rodents that threaten 420 species and NBSP ;. Or cats that are well known to the decimation of local populations of birds and other creatures that they find their prey. cats threaten& Nbsp; 430 species. In addition, when compared with other pathogens wildlife& NBSP;B. dendrobatidis& NBSP; still orders & NBSP; more devastating than & NBSP; Two well-known diseases combined. White nose syndrome & NBSP; affects the & NBSP;Six species of bats and& NBSP; West Nile virus& NBSP; 23 species of birds, 23 species combined. & NBSP;

The researchers found three& NBSP;risk& NBSP;factors for amphibian species that with & # 39 are & NBSP; correlate& NBSP;with the greatest loss of chytridiomycosis.

Greater reliance on aquatic habitats, especially the year.

Floating species living in wet or aquatic habitats all year are at greater risk chytridiomycosis.

Amphibian species that lived in areas that were consistently wet or waterlogged during the year were in much greater danger & NBSP;. Chytridiomycosis & NBSP;B. dendrobatidis & NBSP;It dies when dry, so amphibians, which spend part of the year or part of their life is completely out of the water reduces your chances of getting the disease simply by avoiding, where it can survive and develop.

Larger body size.

Cane toads are quite large. They may weigh about 1 kg and reach 25 cm in length.

Typically, organisms with larger body size need more time to grow and reproductive investment. This factor has less to do with the disease and more opportunities species to recover from the heavy losses in population due to chytridiomycosis.

Life on the hills or living in a relatively smaller range.

These factors are linked, as generally have higher elevations less square. Imagine a ring around a high evaluation on a mountain top, compared with the ring circling its base – the area on the hills is significantly less & NBSP; species can move up the mountain to establish a more suitable habitat due to climate change .. But as you climb up the mountain, there is less and less space. Also, if species are able to cover a wide range, there is a greater change, they will be able to find areas to live and avoid chytridiomycosis, unlike amphibian species that rely on a particular field.

Globalization has helped to & NBSP; the spread of disease, as our world becomes more physically connected. Fungal pathogens are often overlooked. Moreover, amphibians under threat, but also food security and human health. Understanding how the disease will vary in accordance with the climate change will help us with the disease & NBSP; forecasting and mitigation of the spread of infectious diseases in our wildlife, the ecosystem we live in, the crops we rely on and even in ourselves.

In addition, when compared with other pathogens wildlife B. dendrobatidis It is still orders of magnitude more devastating than the two well-known diseases combined.
