Genetics Say A New Species Of Frog Can Have A Doppelganger
2014-08-11 03:41:59

University of Kansas Recently, Malaysian herpetologist Juliana Senawi puzzled over an unfamiliar orange-striped, yellow-speckled frog she’d live-caught in swampland on the Malay Peninsula. She showed the frog to Chan Kin Onn, a fellow herpetologist pursuing his doctorate at the University of Kansas. They wondered — was this striking frog with an appearance unlike others nearby in the central peninsula an unidentified species? Poring over records to find out, the researchers saw...

This frog species, which once hopped throughout California’s upper elevations, has dropped significantly in numbers, more than ninety percent in the past decade, due in part to chytrid, a skin fungus that thickens the frog’s skin so they can’t breathe. Oakland, CA (PRWEB) January 29, 2014 On Wednesday, February 5, 2014, from 6:30pm – 9:30pm, the public is invited to attend a Conservation Speaker Series focused on saving the mountain yellow- legged frog. This frog species, which...

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...

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...

Underground Adventures Of A Mediterranean Frog
2013-04-30 10:45:25

Pensoft Publishers Do frogs live underground? The answer is yes, some amphibians, such as salamanders and frogs have been often reported to dwell in subterranean habitats, some of them completely adjusted to the life in darkness, and others just spending a phase of their lifecycle in an underground shelter. Up until 2010, however, no one suspected that the Mediterranean anuran frog Rana iberica - commonly known as Iberian brown frog and usually found in streams - also participates in...

American bullfrogs are native to eastern North America but have been transported by people to many other parts of the globe, and other parts of North America, where they have readily established populations and become an invasive alien menace to native ecosystems. In the largest study of its kind to date, the stomach contents of over 5,000 invasive alien American bullfrogs from 60 lakes and ponds on southern Vancouver Island were examined to identify the native and exotic animals that they...

Image 1 - New Frog Species Discovered In New York City
2012-03-15 09:26:58

New York City has many mysteries, however this latest has scientists scratching their heads.  How did an entire species of frog - in one of the nation´s most crowded and oldest cities - go undiscovered for as long as it did? In 2009, Jeremy A. Feinberg, a doctoral candidate in ecology and evolution at Rutgers University, heard a strange single croak as he was listening for the multiple croaks of the southern leopard frog in mating season. “I started hearing these calls,...

In the wilds of New York City – or as wild as you can get so close to skyscrapers – scientists have found a new leopard frog species that for years biologists mistook for a more widespread variety of leopard frog. While biologists regularly discover new species in remote rain forests, finding this one in the ponds and marshes of Staten Island, mainland New York and New Jersey – sometimes within view of the Statue of Liberty – is a big surprise, said the scientists...

Springy Tendons Key To Frogs' Amazing Leaps
2011-11-17 04:08:54

The secret to frogs´ superlative jumping lies in their tendons. Researchers at Brown University, filming frogs jumping at 500 frames per second with special X-ray technology, show that the frog's tendon stretches as it readies its leap and then recoils, much like a spring, when the frog jumps. The finding could explain how other animals are exceptional leapers. Results appear in Biology Letters. Some species of frogs and many other animals are able to jump far beyond what appear to be...

Lowland Leopard Frog, Rana yavapaiensis
2013-08-19 13:33:34

The Lowland Leopard Frog (Rana yavapaiensis), is a species of frog belonging to the Ranidae family that is located in Mexico and the United States. Its natural habitats include temperate forests, freshwater lakes, intermittent rivers, rivers, and freshwater marshes. In most populations, breeding normally occurs following springtime emergence after a period of winter inactivity and continues through summer and into the fall. Within the wild, masses of eggs have been observed to hatch in...

Crawfish Frog, Rana areolata
2013-07-26 19:14:26

The Crawfish Frog (Rana areolata or Lithobates areolatus) is a medium-sized species of frog endemic to the prairies and grasslands of the central United States. Its name comes from the fact that it inhabits the burrows of crayfish for the majority of the year. The crawfish frog grows from 2.2 to 3.0 inches long. It ranges from yellow to brown in coloration, with a white ventral surface. The numerous dark brown colored spots featured on its back each have a light-colored ring around it. It...

Moor Frog, Rana arvalis
2013-07-26 19:02:45

The Moor Frog (Rana arvalis) is a slim, reddish brown colored, and semiaquatic amphibian that is native to Europe and Asia. It belongs to the Ranidae family, or true frogs. Ranidae, the family that the Moor Frog belongs to, is a wide group covering about 605 species. The family is like a "catch-all" for ranoid frogs that don't belong to any other families. Seeing that this is the case, the traits that define them are more general, and the frogs are found all throughout the world, on every...

Pool Frog, Pelophylax lessonae
2013-07-19 16:18:52

The Pool Frog (Pelophylax lessonae) is a European frog. It's one of only four amphibian species that is recognized by the UK government as protected under its Biodiversity Action Plan. The reasons for declining populations are decreased pond habitat from human encroachment in order to honor his master Michele Lessona. This frog hasn't always been recognized as a native British species. A part of the reason for this is that other similar species are known to have been introduced. However,...

Japanese Wrinkled Frog, Glandirana rugosa
2013-07-19 13:33:53

The Japanese Wrinkled Frog (Glandirana rugosa) is a species of true frog endemic to Japan and introduced to Hawaii in the late 19th century. It has occasionally been regarded as a single species with the Imienpo Station Frog, Glandirana emeljanovi, which is located on the East Asian mainland. The two species are distinguished from other frogs by their rough and uneven skin. It resides and breeds in a variety of freshwater environments, including ponds, streams, and wetlands. The IUCN doesn't...
