New York and Washington, DC Events Highlight Research Methodology on Amphibian Declines Implemented to Study Honey Bees NEW YORK, June 6, 2012 /PRNewswire-USNewswire/ -- EcoHealth Alliance, a nonprofit organization that focuses on local conservation and global health issues, announced this week at New York City and Washington, DC events the expansion of its programs to include the study of honey bee health. Leveraging the organization's independent scientific expertise, EcoHealth...

Critically Endangered Frogs Surviving In New Home
2012-05-03 13:14:48

The Durrell Wildlife Conservation Trust reports that a critically endangered frog species has found new hope in a new home. The conservationists reported that captive "mountain chicken" frogs that were reintroduced to the Caribbean island of Montserrat are alive and well. The mountain chicken frogs are one of the world's largest frog species, but its population has declined by as much as 80 percent in the wild.  Some of the female frogs can weigh a couple of pounds. "Due to...

Deadly Fungus Causing Dehydration In Wild Frogs
2012-04-27 04:47:07

According to a new study, the fungal infection killing amphibians around the world is causing deadly dehydration in frogs in the wild. The scientists say that high levels of Batrachochytrium dendrobatidis (Bd), the fungus known as the culprit behind the death of the frogs, disrupts fluid and electrolyte balance in the frogs.  As a result, the amphibians' sodium and potassium levels are depleted, causing cardiac arrest and death. San Francisco State University biologist Vance...

Known for its distinctive "ribbit" call, the noisy Pacific chorus frog is a potent carrier of a deadly amphibian disease, according to new research published today in the journal PLoS ONE. Just how this common North American frog survives chytridiomycosis may hold clues to protect more vulnerable species from the disease. Chytrid has wiped out more than 200 frog species across the world and poses the greatest threat to vertebrate biodiversity of any known disease. In California's Sierra...

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...

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
2011-08-29 03:38:59

  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...
