Sometimes divers, to their own painful dismay, do belly flops. But did you ever see a frog belly flop? That's just what primitive living frogs do, according to a new study by Dr. Richard Essner, from Southern Illinois University Edwardsville in the US, and colleagues, looking at the evolution of frog jumping and landing. They found that frogs became proficient at jumping before they perfected landing. This evolutionary split, characterized by an inability to rapidly rotate the limbs forward...

Incidence of a lethal infectious disease moves at a rate of 30 kilometers per year A killer has been caught in the act: the first before-and-after view of an infectious disease that led to an amphibian die-off has been released by the scientists who tracked it. The results are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). Like a wave, incidence of the fungal disease that wipes out Central American frogs--chytridiomycosis--advances through the...

Dr Andrew Johnson is speaking today (July 12) at the UK National Stem Cell Network annual conference. He and his team from the University of Nottingham have been using a Mexican aquatic salamander called an axolotl to study the evolution and genetics of stem cells - research that supports the development of regenerative medicine to treat the consequences of disease and injury using stem cell therapies. This team has found that there are extraordinary similarities in the development of...

As global warming threatens many animal species with extinction, the already destructive cane toad is set to flourish with increasing temperature, say Australian scientists "The negative effect of high temperature does not operate in Cane Toads, meaning that toads will do very well with human induced global warming", explains Professor Frank Seebacher from the University of Sydney. Unlike fish and other cold-blooded creatures, whose oxygen transport system suffers at high temperatures, the...

Trying to stay ahead of a deadly disease that has wiped out more than 100 species, scientists at the Smithsonian Tropical Research Institute continue to discover new frog species in Panama: Pristimantis educatoris, from Omar Torrijos National Park, and P. adnus from Darien Province near the Colombian border. In 1989 researchers realized that frogs were dying around the world. Then they identified the cause: a fungal disease called chytridiomycosis. In 2004 Karen Lips, associate professor at...

Using experiments involving a mechanical shaker and a robotic frog, researchers reporting online on May 20th in Current Biology, a Cell Press publication, have found new evidence that male red-eyed treefrogs communicate with one another in aggressive contests by using vibrations they send through their plant perches. The findings open the door to further study of what has been a neglected channel for vertebrate communication. "In the case of red-eyed treefrogs, tremulation displays in which...

The world's most ancient frogs may soon be mined to extinction, if the New Zealand government's plans to open up a conservation area for mining go ahead. The primitive Archey's frog (Leiopelma archeyi) and Hochstetter's frog (Leiopelma hochstetteri) are two of the species that inhabit the area of 'high conservation value' on New Zealand's North Island where the mining is planned to take place. Archey's frog is currently ranked top of the Zoological Society of London's (ZSL) EDGE of Existence...

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 team of scientists led by the Department of Energy's Joint Genome Institute (JGI) and the University of California, Berkeley, is publishing this week the first genome sequence of an amphibian, the African clawed frog Xenopus tropicalis, filling in a major gap among the vertebrates sequenced to date. "A lot of furry animals have been sequenced, but far fewer other vertebrates," said co-author Richard Harland, UC Berkeley professor of molecular and cell biology. "Having a complete catalog of...

USDA Forest Service researchers found that site fidelity, the tendency to return to previously occupied habitats, is strong in the Sierra Nevada yellow-legged frog. Research showed how the cumulative effects of a changing climate and introduced non-native trout are negatively impacting the habitat of a species already gone from 90 percent of its historic localities, and will further stress frogs with strong site fidelity. In a 10-year study using mark-recapture methods, Kathleen Matthews and...

Western Toad, Anaxyrus Boreas
2014-08-29 10:52:14

The Western Toad, Anaxyrus boreas, or more commonly known as Bufo boreas, is a large toad species of western North America. It grows to between 5.6 and 13 centimeters long. It has a white or cream colored dorsal stripe, and is dusky gray or greenish dorsally with skin glands concentrated within the dark blotches. Its parotoid glands are oval shaped, widely separated, and larger than the upper eyelids. It features a mottled venter and horizontal pupils but it lacks cranial crests. Compared...

Costa Rican Variable Harlequin Toad, Atelopus Varius
2014-08-29 09:49:13

The Costa Rican Variable Harlequin Toad, Atelopus varius, known also as the clown frog, is a neo-tropical true toad belonging to the family Bufonidae. Ranging once from Costa Rica to Panama, A. varius is currently listed as critically endangered and has been decreased to a single remnant population near Quepos, Costa Rica and is assumed to be extinct within Panama. Some recent variation in the air temperature, precipitation, stream flow patterns, and the following spread of a pathogenic...

Archey’s Frog, Leiopelma archeyi
2014-08-27 09:54:56

Archey’s frog (Leiopelma archeyi) is one of three or four living species within the Leiopelma genus, which holds frogs that are native to New Zealand. This species can only be found along the Coromandel Peninsula and because it has not changed much throughout the past two hundred million years, it is considered to be a living fossil. Little is known about the habits of Archey’s frog, but it is known to be terrestrial, inhabiting damp areas at high elevations. It is thought that males...

Maud Island Frog, Leiopelma pakeka
2014-08-22 10:38:14

The Maud Island frog is native to New Zealand, first discovered in the 1940’s. Originally classified as the same species as the Hamilton’s frog, it was reclassified in 1998 as its own species. The Maud Island frog is one of the oldest species known. It has been in existence for roughly 200 million years. In 2006, 60 Maud Island frogs were introduced to a predator free sanctuary. Thirty others were also released outside the sanctuary for comparison. In February 2008, 13 juvenile frogs...

Palawan Horned Frog, Megophrys ligayae
2014-08-21 11:52:00

The Palawan horned frog is native to the Philippines where the habitat is tropical or subtropical dry forests, moist lowland forests, moist shrub land, and rivers. Habitat loss is a contributing factor in the reduction of the population of this species. It is listed as endangered on the IUCN list. The color of this species is a light brown or grey with two ridges running down the back and a dark triangular patch behind the dark brown eyes. It has a large and wide head with a pointed snout....
