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...

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

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...

Endangered Frogs Saved By Genetic Matchmaking

Smithsonian Tropical Research Institute What if Noah got it wrong? What if he paired a male and a female animal thinking they were the same species, and then discovered they were not the same and could not produce offspring? As researchers from the Smithsonian's Panama Amphibian Rescue and Conservation Project race to save frogs from a devastating disease by breeding them in captivity, a genetic test averts mating mix-ups. At the El Valle Amphibian Conservation Center, project...

A Yale graduate student has developed a novel means for charting the history of a pathogen deadly to amphibians worldwide. Katy Richards-Hrdlicka, a doctoral candidate at the Yale School of Forestry & Environmental Studies, examined 164 preserved amphibians for the presence of Batrachochytrium dendrobatidis, or Bd, an infectious pathogen driving many species to extinction. The pathogen is found on every continent inhabited by amphibians and in more than 200 species. Bd causes...

Deadly Fungus Causing Dehydration In Wild Frogs

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...

Athletic Frogs Have Faster-Changing Genomes
2012-04-13 07:59:11

Durham, NC – Physically fit frogs have faster-changing genomes, says a new study of poison frogs from Central and South America. Stretches of DNA accumulate changes over time, but the rate at which those changes build up varies considerably between species, said author Juan C. Santos of the National Evolutionary Synthesis Center in Durham, North Carolina. In the past, biologists trying to explain why some species have faster-changing genomes than others have focused on features...

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...

Scientists have unraveled the dynamics of a deadly disease that is wiping out amphibian populations across the globe. New findings, published May 10 in the Proceedings of the National Academy of Sciences, suggest that infection intensity -- the severity of the disease among individuals -- determines whether frog populations will survive or succumb to an amphibian fungal disease called Chytridiomycosis. The research identifies a dangerous tipping point in infection intensity, beyond which...

A workshop at the Smithsonian Tropical Research Institute in Panama has dramatically improved the ability of conservationists and regulatory agencies to monitor the spread of chytridiomycosis"”one of the deadliest frog diseases on Earth. Caused by the chytrid fungus, Batrachochytrium dendrobatidis, this disease is probably responsible for the extinction of nearly 100 frog species since the 1970s. During the past decade, the epidemic swept from the highlands of Costa Rica through western...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
