New frog species leaves scientists' fingers yellow

2012-05-22T16:19:00Z

A beautiful, yellow frog species has been discovered in western Panama, according to a new paper in ZooKeys. Scientists were surprised when handling the new species to find their fingers stained bright yellow by its skin, but even after laboratory research the purpose of this dye remains a mystery. The new species, named Diasporus citrinobapheus, is a member of the large rain frog family, whose members skip the tadpole stage and instead are born directly from eggs as tiny froglets.

2012-04-28T15:16:00Z

Today is Save the Frogs Day, a global event that aims to raise awareness on the plight of amphibians, which are increasingly endangered by climate change, habitat loss and degradation, pollution, invasive species, overexploitation, and the outbreak of a deadly fungal disease. In recognition of Save the Frogs Day, there are dozens of activities occurring around the world.

Mad frog bonanza: up to 36 new frogs discovered in tiny Madagascar forest

2012-04-19T18:05:00Z

A forest less than half the size of Manhattan sports an astounding number of frogs, according to a new paper in Biodiversity Conservation. Two surveys of Madagascar's Betampona Nature Reserve, which covers 2,228 hectares, has uncovered 76 unique frogs, 36 of which may be new to science. To put this in perspective: the U.S. and Canada combined contain just 88 frog species, but cover an area nearly a million times larger than Betampona.

Two new frogs discovered in Philippines spur calls for more conservation efforts

2012-04-19T13:59:00Z

Two new frogs have been discovered on the Philippine island of Leyte during a biological survey last year by Fauna and Flora International, which also recorded a wealth of other species. Discovered in November on the island's Nacolod mountain range, the frogs have yet to be named. The Philippines is one of the world's global biodiversity hotspots, yet suffers from widespread deforestation and degradation.

A pair of researchers have rediscovered a long-lost frog in the tiny African country of Burundi. Known as the Bururi long-fingered frog (Cardioglossa cyaneospila), the species hadn't been seen for over 60 years—since the Soviet Union tested its first nuclear weapon in 1949—but was rediscovered in Bururi Forest Reserve.

Tink frog calls allow researchers to measure population

2012-03-19T16:48:00Z

Given their often tiny size and cryptic nature, how does one determine frog populations in the rainforest? Just eavesdrop. A new study in mongabay.com's open access journal Tropical Conservation Society (TCS) employed automated recorders to listen to amphibian calls to determine if the common tink frog (Diasporus diastema) could be found in recovering secondary forests in Costa Rica.

World's most toxic frog gets new reserve

2012-03-05T15:39:00Z

Touching a wild golden poison frog could kill you within minutes: in fact, a single golden poison frog, whose Latin name Phyllobates terribilis is even more evocative than its common one, is capable of killing 10 humans with its one milligram dose of poison. Yet the deadly nature of this tiny frog has not stopped it from nearing extinction. Now, in a bid to save the species, the World Land Trust (WLT) and Colombian NGO ProAves have teamed up to establish a 50 hectare (124 acres) reserve in the Chocó rainforest.

Celebrate frogs on leap day!

2012-02-20T16:25:00Z

The NGO Amphibian Ark is asking frog-lovers to visit their local zoos on up-coming leap day, February 29th.

Vampire and bird frogs: discovering new amphibians in Southeast Asia's threatened forests

2012-02-06T18:25:00Z

In 2009 researchers discovered 19,232 species new to science, most of these were plants and insects, but 148 were amphibians. Even as amphibians face unprecedented challenges—habitat loss, pollution, overharvesting, climate change, and a lethal disease called chytridiomycosis that has pushed a number of species to extinction—new amphibians are still being uncovered at surprising rates. One of the major hotspots for finding new amphibians is the dwindling tropical forests of Southeast Asia.

Frog perfume? Madagascar frogs communicate via airborne pheromones

2012-01-25T21:05:00Z

Researchers have found that some frogs in Madagascar communicate by more than just sound and sight: they create distinct airborne pheromones, which are secreted chemicals used for communicating with others. A paper published in Angewandte Chemie International Edition relates that some male members of the Mantellinae family in Madagascar use large glands on their inner thighs to produce airborne pheromones. Interestingly, the pheromones are structurally similar to those produced by insects. Scientists have identified frogs producing water-borne pheromones before, but this is the first instance of airborne.

Photos: 46 new species found in little-explored Amazonian nation

2012-01-25T00:02:00Z

South America's tiniest independent nation still hides a number of big surprises: a three week survey to the sourthern rainforests of Suriname found 46 potentially new species and recorded nearly 1,300 species in all. Undertaken by Conservation International's (CI) Rapid Assessment Program (RAP) the survey found new species of freshwater fish, insects, and a new frog dubbed the "cowboy frog" for the spur on its heel. While Suriname may be small, much of its forest, in the Guyana Shield region of the Amazon, remains intact and pristine. The Food and Agriculture Organization (FAO) estimates that 91 percent of Suriname is covered in primary forests, however this data has not been updated in over two decades.

Photos: program devoted to world's strangest, most neglected animals celebrates five years

2012-01-16T18:40:00Z

What do Attenborough's echidna, the bumblebee bat, and the purple frog have in common? They have all received conservation attention from a unique program by the Zoological Society of London (ZSL) called EDGE. Five years old this week, the program focuses on the world's most unique and imperiled animal species or, as they put it, the most Evolutionarily Distinct and Globally Endangered (EDGE) species. In the past five years the program has achieved notable successes from confirming the existence of long unseen species (Attenborough's echidna) to taking the first photos and video of a number of targeted animals (the purple frog).

New frog trumps miniscule fish for title of 'world's smallest vertebrate'

2012-01-12T19:32:00Z

How small can you be and still have a spine? Scientists are continually surprised by the answer. Researchers have discovered a new species of frog in Papua New Guinea that is smaller than many insects and dwarfed by a dime. The frog trumps the previously known smallest vertebrate—a tiny fish—by nearly 1 millimeter.

Frog plague found in India

2012-01-03T21:38:00Z

The chytrid fungus, which is responsible for the collapse of numerous amphibian populations as well as the extinction of entire species, has been located for the first time in India, according to a paper in Herpetological Review. Researchers took swabs of frog in the genus Indirana in the Western Ghats and found the killer fungus known as chytridiomycosis.

The dark side of new species discovery

2011-12-21T23:18:00Z

Scientists and the public usually rejoice when a new species is discovered. But biologist Bryan Stuart has learned the hard way that the discovery of new species, especially when that species is commercially valuable, has a dark side-one that could potentially wipe out the new species before protections can be put in place. Stuart has discovered 27 species unknown previously to scientists - so far. That includes 22 species of frogs, three types of snakes, and two salamanders. His experience with one of these, a warty salamander from Laos with striking markings (Laotriton laoensis), opened his eyes to a dark side of scientific discovery: commercial overexploitation before protections are in place. Shortly after Stuart described the previously unknown species Paramesotriton laoensis in a scientific paper published in 2002, commercial dealers began collecting this Lao newt for sale into the pet trade. In essence, the dealers used Stuart's geographic description in the paper as a “roadmap” to find the rare newt.

Herpetology curator: behind-the-scenes of 'new species' discoveries

2011-12-18T18:11:00Z

Bryan Stuart’s mission as a curator of amphibians and reptiles at the North Carolina Museum of Natural Sciences is to understand the diversity of life on earth. For that, he documents what species occur where and why. He’s particularly attracted to areas where there’s a dearth of knowledge, like Laos, Cambodia, Vietnam and Gabon, and so far has discovered 27 species unknown previously to scientists: three species of snakes, two types of salamanders, and 22 kinds of frogs.

New species of frog sings like a bird

2011-12-12T22:49:00Z

If you're trudging through the high-altitude rainforests of northern Vietnam and you hear bird song, you might want to check the trees for frogs. Yes, that's right: frogs. A new species of tree frog has been discovered in Vietnam that researchers say has a uniquely complex call that makes it sound more like a bird than a typical frog. Discovered in Pu Hoat Proposed Nature Reserve, the new species, dubbed Quang's tree frog (Gracixalus quangi), dwells in the forests at an altitude 600-1,300 meters (nearly 2,000-4,265 feet).

Saving Ghana's vanishing frogs

2011-11-02T18:54:00Z

Frogs need all the help they can get. With the IUCN Red List estimating that 41 percent of amphibians are endangered, frogs are currently the world's most imperiled animal family. Scientists estimate that around 200 amphibian species have been lost to extinction in recent decades to habitat loss, pollution, and a devastating fungal disease. Yet as the frog emergency worsens, there have been positive movements in conservation. The most recent comes from the small West African country of Ghana. Partnering with the enthusiastic US-based organization, SAVE THE FROGS!, two Ghanaian herpetologists, Gilbert Baase Adum and Caleb Ofori, have started a sister branch in their country: SAVE THE FROGS! Ghana.

Scientists find frog genes that provide immunity to extinction plague

2011-09-27T19:46:00Z

Scientists with Cornell have discovered genetics that may provide immunity to frogs in face of the killer amphibian-disease chytridiomycosis. This plague, which is spreading to amphibian populations worldwide, is responsible for a number of frog species' recent extinction. But now researchers report in a new study in the Proceedings of the National Academy of Sciences (PNAS) that they are one step closer to understanding why some frog populations are able to fend off the disease, while others succumb with lightning-speed. In time, the results may lead to breeding strategies in captivity that could produce immune populations.

2011-08-09T21:31:00Z

Ten new species of frog have been discovered in India's Western Ghats according to two new papers in Biosystematica. Although human populations have farmed in the Western Ghats for centuries, the new discoveries prove that the rainforest still holds many surprises. The Western Ghats lie along India's west coast and have been dubbed one of the world's biodiversity hotspots, but the rich wildlife is imperiled by rising human impacts.

Balancing agriculture and rainforest biodiversity in India’s Western Ghats

2011-08-08T19:31:00Z

When one thinks of the world's great rainforests the Amazon, Congo, and the tropical forests of Southeast Asia and Indonesia usually come to mind. Rarely does India—home to over a billion people—make an appearance. But along India’s west coast lies one of the world's great tropical forests and biodiversity hotspots, the Western Ghats. However it's not just the explosion of life one finds in the Western Ghats that make it notable, it's also the forest's long—and ongoing—relationship to humans, lots of humans. Unlike many of the world's other great rainforests, the Western Ghats has long been a region of agriculture. This is one place in the world where elephants walk through tea fields and tigers migrate across betel nut plantations. While wildlife has survived alongside humans for centuries in the region, continuing development, population growth and intensification of agriculture are putting increased pressure on this always-precarious relationship. In a recent paper in Biological Conservation, four researchers examine how well agricultural landscapes support biodiversity conservation in one of India's most species-rich landscapes.

The Bornean rainbow toad, also known as the Sambas Stream toad (Ansonia latidisca) was rediscovered on Borneo in the Malaysian state of Sarawak by local scientists inspired by a 2010 search for the world's missing amphibians by Conservation International (CI). Leading up to its search CI released the World's Top 10 Most Wanted Lost Frogs (out of a hundred being searched for): the Bornean rainbow toad was listed as number 10.

Amphibian-plague strikes frogs harder in pristine ecosystems

2011-05-31T15:35:00Z

Frog populations worldwide are facing two apocalypses: habitat destruction and a lethal plague, known as chytridiomycosis. Over 30 percent of the world's amphibians are currently threatened with extinction and it is thought at least 120 species have gone extinct in just the last 30 years. Unfortunately, a new study in Proceedings of the National Academy of Sciences (PNAS) finds that the two threats—habitat loss and chytridiomycosis—are likely to leave no frog population undisturbed. According to the study, frogs that live in still-pristine habitats are more susceptible to chytridiomycosis than those that are already suffering from habitat loss.

Frog pictures for Save the Frogs Day

To raise awareness of the plight of amphibians, in 2009 biologist Kerry Kriger declared April 28th "Save the Frogs Day". This year the event focuses on Atrazine, a commonly used pesticide which triggers reproductive problems in frogs and humans. Atrazine is used primarily on corn. In recognition of Save the Frogs Day, here is a collection of frog photos taken Mongabay.com's Rhett Butler.

Scientists scramble to save dying amphibians

2011-04-28T17:41:00Z

In forests, ponds, swamps, and other ecosystems around the world, amphibians are dying at rates never before observed. The reasons are many: habitat destruction, pollution from pesticides, climate change, invasive species, and the emergence of a deadly and infectious fungal disease. More than 200 species have gone silent, while scientists estimate one third of the more than 6,500 known species are at risk of extinction. Conservationists have set up an an emergency conservation measure to capture wild frogs from infected areas and safeguard them in captivity until the disease is controlled or at least better understood. The frogs will be bred in captivity as an insurance policy against extinction.

Save the Frogs Day focuses on banning Atrazine in US

2011-04-26T18:26:00Z

This year's Save the Frogs Day (Friday, April 29th) is focusing on a campaign to ban the herbicide Atrazine in the US with a rally at the steps of the Environmental Protection Agency (EPA). Kerry Kriger, executive director of frog-focused NGO Save the Frogs! and creator of Save the Frogs Day, says that Atrazine is an important target in the attempt to save amphibians worldwide, which are currently facing extinction rates that are estimated at 200 times the average. "Atrazine weakens amphibians' immune systems, and can cause hermaphroditism and complete sex reversal in male frogs at concentrations as low as 2.5 parts per billion," Kriger told mongabay.com.

Researchers rediscover one of the world's most sought-after lost frogs

2011-02-17T00:00:00Z

The Search for Lost Frogs, a global expedition to uncover amphibian species not seen for decades, has uncovered one of the expedition's most sought-after species: the Pescado stubfoot toad (Atelopus balios). The discovery in Ecuador was one bright spot in a search that revealed more about the crisis and extinctions of frogs than it did about the hopefulness of finding cryptic communities. In total the expedition rediscovered 4 of its 100 targeted species.

Worldwide search for 'lost frogs' ends with 4% success, but some surprises

2011-02-16T23:58:00Z

Last August, a group of conservation agencies launched the Search for Lost Frogs, which employed 126 researchers to scour 21 countries for 100 amphibian species, some of which have not been seen for decades. After five months, expeditions found 4 amphibians out of the 100 targets, highlighting the likelihood that most of the remaining species are in fact extinct; however the global expedition also uncovered some happy surprises. Amphibians have been devastated over the last few decades; highly sensitive to environmental impacts, species have been hard hit by deforestation, habitat loss, pollution, agricultural chemicals, overexploitation for food, climate change, and a devastating fungal disease, chytridiomycosis. Researchers say that in the past 30 years, its likely 120 amphibians have been lost forever.

Photos: new super tiny frogs discovered in Sri Lanka, one critically endangered

2011-02-09T16:45:00Z

Two new incredibly small frogs have been discovered in Sri Lanka, an island nation off India with at least 100 species of frogs. The new frogs are in the genus Pseudophilautus, which are shrub frogs native either to Sri Lanka or India. One of the new species, dubbed Pseudophilautus hankeni, survives only in high mountain forests, and will likely be classified as Critically Endangered. "These species were discovered as a part of a broad amphibian survey that we carried out about 10 years ago in Sri Lanka. In that survey we discovered nearly 100 new species new to science. We are in the process of describing them now," explained Dr. Madhava Meegaskumbura, who participated in the frogs' discovery and formal description, to mongabay.com.
