New Study Raises Hope To Fight Chytrid Amphibian Pathogen
2014-01-21 15:47:48

Helmholtz-Center for Environmental Research An international team of researchers has made important progress in understanding the distribution of the deadly amphibian chytrid pathogen. In some regions, the deadly impact of the pathogen appears to be hampered by small predators, naturally occurring in freshwater bodies. These micropredators may efficiently reduce the number of free-swimming infectious stages (zoospores) by consuming them. This natural behavior will reduce the infection...

Deadly Fungus Cause Of Frog Declines In The Andes
2013-12-13 07:25:23

San Francisco State University Amphibians at high elevations can tolerate temperature changes, but susceptible to deadly fungus A deadly fungus, and not climate change as is widely believed, is the primary culprit behind the rapid decline of frog populations in the Andes mountains, according to a new study published today in the journal Conservation Biology. Frogs living at higher elevations can tolerate increasing temperatures, researchers found, but their habitats fall within the...

Survey Finds Frog Abnormalities Are Rare
2013-11-20 13:45:34

University of California, Davis A 10-year study shows some good news for frogs and toads on national wildlife refuges. The rate of abnormalities such as shortened or missing legs was less than 2 percent overall — indicating that the malformations first reported in the mid-1990s were rarer than feared. But much higher rates were found in local "hotspots," suggesting that where these problems occur they have local causes. The results were published Nov. 18 in the journal PLOS ONE. "We...

The herbicide atrazine increased mortality from chytridiomycosis, a disease causing worldwide amphibian declines The combination of the herbicide atrazine and a fungal disease is particularly deadly to frogs, shows new research from a University of South Florida laboratory, which has been investigating the global demise of amphibian populations. USF Biologist Jason Rohr said the new findings show that early-life exposure to atrazine increases frog mortality but only when the frogs were...

Studying The Science Behind Bullfrog Jumping Abilities
2013-10-17 11:01:22

[ Watch the Video: Getting Bullfrogs To Jump For Science ] Michael Harper for redOrbit.com - Your Universe Online Physically speaking, bullfrogs should be able to cover more distance in a single hop then they often do. Scientists have observed such amphibians clearing about four feet per jump, but rarely more than this, while other frog species can travel at more than seven feet per hop. Yet frog jumping contests, such as the world famous Calaveras County Jumping Frog Jubilee, have...

Bullfrogs Spreading Deadly Fungus Also Die From It
2013-06-18 07:29:03

April Flowers for redOrbit.com - Your Universe Online There is currently a global decline in amphibian populations. It is believed that a major cause for this decline is a fungus thought to be spread by bullfrogs. A two-year study from Oregon State and the University of Pittsburgh reveals bullfrogs are not only tolerant carriers that spread the disease, as previously thought. The bullfrogs are also dying from the pathogen. The research team raised bullfrogs from eggs in controlled...

United States Amphibian Populations Rapidly Declining
2013-05-25 05:57:30

redOrbit Staff & Wire Reports - Your Universe Online The number of frogs, toads and salamanders in the US could be falling at an even more severe and widespread rate than previously believed, and even amphibian populations thought to be stable are actually on the decline, according to new research for the US Geological Survey (USGS). The study, which was published earlier this week in the journal PLOS ONE, is believed to be the first-ever estimate of how quickly amphibians across...

African Clawed Frog Responsible For Spreading Deadly Fungus
2013-05-16 11:58:36

Brett Smith for redOrbit.com - Your Universe Online For years, scientists have been on the trail of a slippery culprit responsible for a deadly fungus, and they´ve finally found the culprit. The fungus, called Batrachochytrium dendrobatidis,“¯or ℠Bd´ for short, has played a role in the recent decline or extinction of 200 frog species worldwide. According to a new report in the open-access journal“¯PLOS ONE, long-suspected African clawed frogs have...

American Bullfrog Is Spreading Chytrid Through Commercial Trade
2013-03-07 09:27:12

Wildlife Conservation Society A team of scientists led by the Wildlife Conservation Society (WCS) and the National University of Singapore (NUS), revealed in a new study, for the first time, the presence of the pathogenic chytrid fungus (Batrachochytrium dendrobatidis) in amphibians sampled in Singapore. And the American bullfrog may be a central player in the spread of the disease. The study appears in the current issue of the journal EcoHealth, and is the first to consider the role...

Frog Diseases Increasing
2012-07-19 10:38:29

Brett Smith for redOrbit.com - Your Universe Online In addition to the stresses placed on amphibians, or perhaps because of them, they are now more likely to succumb to debilitating infectious diseases. In recent decades, disease seems to have taken a more prominent role in the amphibian mortality rate, according to a new study published in Philosophical Transactions of the Royal Society B. Along with climate change, habitat destruction, pollution and invasive species, these creatures...
