Amphibians In Regions With Diversity Are Most At Risk
2011-11-17 12:55:16

According to new research, tropical regions with the richest diversity are most at risk of losing frogs, toads, newts and salamanders. Scientists predict the future for these amphibians is even more bleak than conservationists had thought. They predict that areas with the highest diversity of amphibian species will be under the most intense threat in the future.  About half of amphibian species are in decline, while a third that are already threatened with extinction. The...

Amphibian populations are declining worldwide, and their declines far exceed those of other animal groups: more than 30% of all species are listed as threatened according to the Red List of the International Union for the Conservation of Nature (IUCN). Multiple factors threaten global amphibian diversity but the spatial distribution of these threats and their interactions are poorly known. A new study published in Nature with Dr. Christian Hof as lead author indicates that, worryingly, areas...

Frog Fungus Spread Throughout The World Via Trade
2011-11-09 13:06:06

According to new research, a killer frog fungus that is spreading around the world is being distributed through amphibian trade by zoos and collectors. Scientists said that the most widespread and lethal form of the three distinct lineages of the chytrid fungus was probably created by a crossing of two prior forms. Chytrid is now found on every continent and has wiped out a number of species. The fungus kills amphibians by blocking the transfer of vital substances through their...

Scientists Establish Cell Cultures Of Endangered Frog
2011-11-04 03:49:23

San Diego Zoo Global Wildlife Conservancy scientists have taken a tremendous leap forward in banking viable amphibian cells. This was achieved through the first successful establishment of cell cultures from frozen biopsy specimens of the critically endangered Mississippi gopher frog. A method called "tissue piecing" and immediate freezing in liquid nitrogen allows field biologists to collect samples that can later be processed in a laboratory. "With amphibians we have found that we can...

Image 1 - Amphibians: Beware Young Beetles' Deadly 'Siren Call'
2011-09-26 10:45:50

   In role reversal, carnivorous ground beetle stalks its amphibian prey, says Tel Aviv University researcher Ground beetles can immobilize and devour amphibian prey many times their size. Now Gil Wizen, a graduate student of Tel Aviv University's Department of Zoology, has discovered that they have an additional advantage – the larvae of these beetles, like their fully grown adult counterparts, have a unique method for luring and feeding off amphibians. Wizen's...

Researchers at Oregon State University have shown for the first time that loss of biodiversity may be contributing to a fungal infection that is killing amphibians around the world, and provides more evidence for why biodiversity is important to many ecosystems. The findings, being published this week in Proceedings of the National Academy of Sciences, used laboratory studies of amphibians to show that increased species richness decreased both the prevalence and severity of infection...

Daphnia magna

  Oregon State University (OSU) researchers have discovered a breed of freshwater zooplankton that they say can help combat a fungus that has been devastating amphibian populations around the world. According to the International Business Times, this particular species of zooplankton is known as Daphnia magna, a variety of aquatic flea from the genus Daphnia. They say that these organisms "could provide a desperately needed tool for biological control of the deadly fungus whose...

SF State's Vance Vredenburg and team continue focus on mass extinction of amphibians An international team of researchers has completed the first major survey in Asia of a deadly fungus that has wiped out more than 200 species of amphibians worldwide. The massive survey could help scientists zero in on why the fungus has been unusually devastating in many parts of the globe -- and why Asian amphibians have so far been spared the same dramatic declines. The disease chytridiomycosis, caused by...

The first study by National University of Singapore, University of Adelaide and Princeton University researchers reveals that at least 351 species thought to have disappeared in the past 122 years, have been rediscovered Extinction is a focal issue among scientists, policy makers and the general public. Each year, numerous species which are thought to have disappeared are rediscovered. Yet, these rediscoveries remain on the brink of extinction. Researchers from the National University of...

The world's ravenous appetite for consuming thousands of tons of frogs' legs every year is driving the amphibians to extinction, and could have a significant impact on bio-diversity, according to a new report by international wildlife conservation groups. The report, entitled "Canap©s to Extinction: The international trade in frogs' legs and its ecological impact", was authored by the groups Pro Wildlife, Defenders of Wildlife and the Animal Welfare Institute, and is the first...

The Strawberry Poison-Dart Frog, Oophaga Pumilio or Dendrobates Pumilio, is a species of small amphibian poison dart frog located in Central America. It’s common throughout its range, which stretches from eastern central Nicaragua through Costa Rica and northwestern Panama. The species is frequently found in humid lowlands and premontane forest, but populations of large size are also found in disturbed areas such as plantations. This frog is perhaps most famous for its widespread varieties...

The Mindanao horned frog, also known as the Southeast Asian horned toad, is native to the Philippines and found only on the island of Mindanao. The habitat of this frog is tropical and subtropical moist forests, near ponds and rivers. The Mindanao horned frog can be found in elevations up to 1.5 miles as long as it has an ample water supply for breeding. The Mindanao horned frog has a large head and mouth in comparison to the body. It also has pointed horn-like humps sticking out above the...

The Sagalla caecilian (Boulengerula niedini) is a long, earthworm-like amphibian from the family Caeciliidae. The species is native to the tiny area of south-eastern Kenya called Sagalla Hill. The Sagalla caecilian has a slender body, perfect for burrowing. Its skin is extremely pigmented, lending it a brownish color with a pinkish-red hint, and white cross segments that give the appearance of grooves. They can grow up to 12 inches in length. Along with tough skin and a bony head, the...
