(10/26/2010) A new report by the World Wide Fund for Nature (WWF) confirms the Amazon rainforest, even as it is shrinking due to deforestation, remains among the world's most surprising places. According to the report, Amazon Alive, over the past decade (1999-2009) researchers have found 1,200 new species in the Amazon: one new species for every three days. Not surprisingly invertebrates, including insects, made up the bulk of new discoveries. But no type of species was left out: from 1999-2009 researchers discovered 637 new plants, 357 fish, 216 amphibians, 55 reptiles, 39 mammals, and 16 new birds. In new discoveries over the past decade, the Amazon has beaten out a number of high-biodiversity contenders including Borneo, the Eastern Himalayas, and the Congo rainforest.
Elephant tromping benefits frogs and lizards
(10/25/2010) While elephants may appear destructive when they pull down trees, tear up grasses or stir up soils, their impacts actually make space for the little guys: frogs and reptiles. The BBC reports that a new study in African Journal of Ecology finds that African bush elephants (Loxodonta Africana), facilitate herpetofauna (i.e. amphibians and reptiles) biodiversity when they act as ecosystem engineers.
Photos: three new forest frogs discovered in Tanzania
(10/19/2010) Africa's most biodiverse nation, Tanzania, has added a few more species to its dockets. Researchers have discovered three new amphibians in the always surprising Eastern Arc Mountains, a region which has supplied a number of new species recently. All three new species are members of the frog genus Callulina. Described in the Zoological Journal of the Linnean Society the researchers warn that all three of the new frogs are confined to small habitats threatened by deforestation and firewood collection.
Photos: 200 new species discovered in 60-day expedition in New Guinea
(10/06/2010) A 2009 expedition to Papua New Guinea proves once again that the island-nation is as diverse in life as it is in human cultures. It took researchers with Conservation International (CI) and the local Institute for Biological Research (IBR) just two months to uncover a startling 200 new species: averaging more than 3 a day in the remote Nakanai Mountains and Muller Range rising from the island of New Britain, a part of Papua New Guinea. Half of the new species were spiders, but the team also found two new mammals, nine new plants, two dozen frogs, and multitude of insects. Most surprising was the discovery of at least two species so unique that they are likely to be assigned their own genus.
Stunning toxic frog protected as a result of drug trafficking conflict
(09/29/2010) A spectacular poison dart frog on the edge of extinction in the wild has been afforded temporary protection by warring drug gangs in Colombia's Chocó region, reports ProAves. The La Brea Poison Frog (Oophaga occultator), a colorful species only documented by scientists in 1975, has suffered from unsustainable collection for the pet trade, severe deforestation for coca cultivation, and aerial spraying for coca eradication, resulting in a substantial population decline. But the species has clung to life in a deforested landscape along the Saija River in Colombian Pacific coast in part due to conflict between three armed groups which has kept collectors out of the area.
Photos: 'Lost amphibian' search makes good: three 'extinct' species rediscovered
(09/22/2010) A search for 100 of the world's 'lost amphibians'—unseen for decades and in many cases supposed extinct—have turned up three species so far, one of which hasn't been recorded since the Nazis were bombing London. The lost amphibian expeditions, formed by Conservation International (CI) and the IUCN Amphibian Specialist Group (ASG), have found surviving populations of the cave splayfoot salamander (Chiropterotriton Mosaueri) in Mexico, the Mount Nimba reed frog (Hyperolius Nimbae) in the Ivory Coast, and the Omaniundu reed frog (Hyperolius sankuruensis) from the Democratic Republic of Congo.
Frogs and friends at risk from booming global wildlife trade
(09/08/2010) Alejandra Goyenechea, International Counsel at Defenders of Wildlife and Chair of the Species Survival Network's (SSN) Amphibian Working Group, spoke with Laurel Neme on her 'The WildLife' radio show and podcast about the global amphibian trade. In her interview, Alejandra Goyenechea discusses the benefits of frogs and the many threats – such as habitat loss, climate change, pollution, invasive species, disease, and overexploitation – to their survival. Did you know frogs indicate environmental quality, like canaries in a coal mine? Or that many have medicinal properties, like the phantasmal poison dart frog which produces a painkiller 200 times the potency of morphine?
Photos: Asia's tiniest frog discovered living inside carnivorous plants in Borneo
(08/25/2010) One of the world's smallest frogs has been discovered living inside carnivorous plants in Borneo, reports Conservation International, a conservation group that is jointly supporting a campaign with IUCN to search for some of the world's 'lost amphibians.' The species, described in Zootaxa by Indraneil Das and Alexander Haas of the Institute of Biodiversity and Environmental Conservation at the Universiti Malaysia Sarawak and Biozentrum Grindel und Zoologisches Museum of Hamburg, is named Microhyla nepenthicola after the plant in which is was found, Nepenthes ampullaria, a species of pitcher plant from Malaysian Borneo.
Exploring Kenya's sky island
(08/18/2010) Rising over 2,500 meters from Kenya's northern desert, the Mathews Range is a sky island: isolated mountain forests surrounded by valleys. Long cut off from other forests, 'sky islands' such as this often contain unique species and ecosystems. Supported by the Nature Conservancy, an expedition including local community programs Northern Rangelands Trust and Namunyak Conservancy recently spent a week surveying the mountain range, expanding the range of a number of species and discovering what is likely a new insect.
Golden toad saved from brink of extinction
(08/17/2010) One hundred Kihansi Spray Toads have been flown to their native Tanzania after a close brush with extinction, reports the Wildlife Conservation Society (WCS).
Photos: world's top ten 'lost frogs'
(08/09/2010) The International Union for the Conservation of Nature (IUCN) and Conservation International (CI) have sent teams of researchers to 14 countries on five continents to search for the world's lost frogs. These are amphibian species that have not been seen for years—in some cases even up to a century—but may still survive in the wild. Amphibians worldwide are currently undergoing an extinction crisis. While amphibians struggle to survive against habitat loss, climate change, pollution, and overexploitation, they are also being wiped out by a fungal disease known as chytridiomycosis.
Scientists hunt for 'lost frogs' around the globe
(08/09/2010) From now through October, teams of scientists will be scouring through leaf litters, in shallow pools, under rocks, and in tree trunks for the world's 'lost frogs'. Searching in 14 countries on five continents, the researchers are looking for some 100 species of frogs that have not been seen in decades and in some cases up to a century. While some of the species may well be extinct, researchers are holding out hope that they can find the ones that are still hanging on, albeit by a thread.
Endangered Animals: 10 Reasons for Hope
(08/03/2010) Earlier last month the Zoological Society of San Diego launched two far reaching media and development projects which showcase the Zoo's extensive global field conservation programs. Mongabay had the opportunity to attend the launch ceremony of the Zoo's new 'Global Action Team' and the accompanying 'Ten Reasons for Hope' campaign. While at this event, we spoke with Alan Lieberman, Director of Regional Conservation Programs, about the development of both projects.
Following public outcry, New Zealand drops plan to mine protected areas
(07/20/2010) The New Zealand government has caved to public pressure, announcing that it is dropping all plans to mine in protected areas. The plan to open 7,000 hectares of protected areas to mining would have threatened a number of rare and endemic species, including two frogs that are prehistoric relics virtually unchanged from amphibian fossils 150 million years old: Archey's frog (Leiopelma archeyi) and Hochstetter's frog (Leiopelma hochstetteri).
30 frog species, including 5 unknown to science, killed off by amphibian plague in Panama
(07/19/2010) With advanced genetic techniques, researchers have drawn a picture of just how devastating the currently extinction crisis for the world's amphibians has become in a new study published in the Proceedings of the Nation Academy of Sciences (PNAS). Studying frog populations using DNA barcoding in Panama's Omar Torrijos National Park located in El Copé researchers found that 25 known species and 5 unknown species have vanished since 1998. None have returned.
Two new frogs discovered in Panama amidst amphibian plague
(06/06/2010) Researchers working to save Panama's frogs from a fatal disease have stumbled on two species unknown to science. In Omar Torrijos National Park they found a bigger version of a common species, which is now known to be a unique species, and near the Colombian border they discovered a new frog that has been named after Spanish for DNA. Both frogs were discovered while researchers searched for frog populations in chytridiomycosis-infected areas. The highly contagious disease chytridiomycosis has devastated frog species worldwide and is believe to be at least in part responsible for some 100 extinctions of amphibians.
18,225 new species discovered in 2008
(05/27/2010) In the 2010 State of Observed Species researchers have announced that 18,225 living species were discovered in 2008. In addition, 2,140 new extinct species were discovered byway of fossils.
World's 'number one frog' faces extinction from New Zealand government
(05/26/2010) Archey's frog is a survivor: virtually unchanged evolutionarily for 150 million years, the species has survived the comet that decimated the dinosaurs, the Ice Age, and the splitting of continents. Seventy million years ago New Zealand broke away from Australia, essentially isolating Archey's frog and its relatives from all predatory mammals. Yet, if the New Zealand government has its way this species may not survive the century, let alone the next few decades. The New Zealand government has put forward a controversial proposal to begin opening three of the nation's protected areas to mining: Great Barrier Island, Paparoa National Park, and Coromandel Peninsula where the last populations of Archey's frogs live. According to critics, the government's proposal could push Archey's frog toward extinction, while negatively impacting a number of other endangered species, beloved wild lands, and a nation driven by tourism.
Photos: more new species found in Indonesia's 'lost world'
(05/17/2010) The Foja Mountains on the Indonesian side of New Guinea have proven a biological treasure trove that just keeps spilling riches. Two-and-a-half years ago the region—dubbed Indonesia's 'lost world'—made news globally when researchers announced the discovery of a giant rat: five times the size of the familiar brown rat. New amphibians, birds, and insects have also been found during past expeditions in 2005 and 2007. A collaborative team of Indonesia and international researchers have since returned to the Foja Mountains and found more spectacular species.
A day to celebrate (and save) the world's amphibians: the 2nd Annual Save the Frogs Day
(04/28/2010) Friday, April 30th is for the frogs: educational programs, conservation walks with experts, frog leaping races, and the world's first protest to save frogs are all planned for the world's 2nd Annual Save the Frogs Day. Organized by the non-profit SAVE THE FROGS!, events are so far planned in 15 countries on every continent besides Antarctica—fittingly the only continent that lacks amphibians.
Environmentalists say President of Philippines not deserving of conservation award
(04/13/2010) Filipino environmentalists and religious leaders have expressed shock and anger that Gloria Macapagal-Arroyo, the President of the Philippines, has been chosen to receive a conservation award from the US Congress in Washington, DC today according to the Philippine Daily Enquirer.
The Asian Animal Crisis
(03/18/2010) The United Nation declared 2010 as the International Year of Biodiversity (IYB). One of the goals of the IYB is to celebrate the achievements of the Convention of Biological Diversity signed by 192 countries since 1992. But what have we accomplished since 1992? Did we put an end to biodiversity loss? The truth is that there is not much to celebrate at all. Asia is a perfect example where the animal crisis and the loss of biodiversity have worsened over decades. The first question that should come to mind is: how many species have vanished in Asia because of human activities? Records of recently extinct species in Asia show 71 species that have disappeared in the wild. Examples include the Yunnan lake newt (Cynops wolterstorffi) from China, the Bonin thrush (Zoothera terrestris) from Japan, or the redtailed black shark (Epalzeorhynchos bicolor) from Thailand.
Frog in Australia goes from 'extinct' to very, very endangered
(03/08/2010) Facing habitat loss, pollution, climate change, and the devastating chytrid fungus, there has been little positive news about amphibians recently. However, a story out of Australia brings a much needed respite from bad news. In 2008 Luke Pearce, a fisheries conservation officer, stumbled on a frog that had been thought to be extinct for over thirty years. Not recorded since the 1970s, Pearce rediscovered the yellow-spotted bell frog (Litoria castanea) on rural Australian farmland in the Southern Tableland of New South Wales.
Website seeking 'most wanted' photos and videos of vanishing species
(03/04/2010) Many of the world's most endangered species have never been photographed or caught on film. The not-for-profit website ARKive is hoping to change that. ARKive provides a collection of some of the best photos and video clips of the world's species.
Photos: Madagascar's wonderful and wild frogs, an interview with Sahonagasy
(03/03/2010) To save Madagascar's embattled and beautiful amphibians, scientists are turning to the web. A new site built by herpetologists, Sahonagasy, is dedicated to gathering and providing information about Madagascar's unique amphibians in a bid to save them from the growing threat of extinction. "The past 20 years have seen resources wasted because of a poor coordination of efforts," explains Miguel Vences, herpetologist and professor at the Technical University of Braunschweig. "Many surveys and reports have been produced that were never published, many tourists found and photographed amphibians but these photos were not made available to mapping projects, many studies carried out by Malagasy students did not make use of literature because it was not available."
Common pesticide changes male frogs into females, likely devastating populations
(03/01/2010) One of the world's most popular pesticides, atrazine, chemically castrates male frogs and in some instances changes them into completely functionally females, according to a new study in the Proceedings of the National Academy of Sciences. The authors conclude that atrazine likely plays a large, but unsuspected role in the current global amphibian crisis.
Forgotten Species: the fiery Luristan Newt
(02/08/2010) The salamander was a mythical creature before it was a real one: the word salamander means a legendary lizard that both survived-in and could extinguish fire. A creature that the Ancient Greeks, including Aristotle, appeared to readily believe in. No one knows how the term salamander transferred from a mythical fire-dwelling monster to the small amphibious animals it applies to today, but I have a theory. Perhaps the sight of salamanders like Luristan newt—charcoal-black and flame-orange—caused people in the seventeenth century to lend the name of myth to the taxa.
Bronx Zoo puts 'extinct' frogs on display
(02/02/2010) The Bronx Zoo has a put a most unusual frog on display: the Kihansi spray toad. For one thing, the Kihansi spray toad survived on only 5 acres in the Kihansi gorge in Tanzania, adapted to the areas' unique and constant mist from the gorge and a waterfall. For another, female Kihansi spray toads give birth to live young, instead of laying eggs. Finally, the Kihansi spray toad is extinct—at least in the wild.
Photos: New tropical frog undergoes remarkable transformation
(02/01/2010) Nature never runs out of surprises. Exploring Sudest Island off of Papua New Guinea, researchers discovered a new species of frog that drastically changes its appearance from juvenile to adulthood, a transformation that has never been seen in another frog.The new species, named Oreophryne ezra, is shiny black with bright yellow spots. Yet when it matures, the frog becomes rose-colored and even its eyes change from black to blue.
Conservation organization, Durrell Wildlife Trust, forced to cut staff due to economic downturn
(01/19/2010) The Durrell Wildlife Trust—which turned fifty last year—has announced that it will be cutting back 10 percent of its workforce, approximately 12-14 positions, due to an ongoing deficit caused by the economic recession.
Photos: park in Ecuador likely contains world’s highest biodiversity, but threatened by oil
(01/19/2010) In the midst of a seesaw political battle to save Yasuni National Park from oil developers, scientists have announced that this park in Ecuador houses more species than anywhere else in South America—and maybe the world. "Yasuní is at the center of a small zone where South America's amphibians, birds, mammals, and vascular plants all reach maximum diversity," Dr. Clinton Jenkins of the University of Maryland said in a press release. "We dubbed this area the 'quadruple richness center.'"
Photos: expedition in Ecuador reveals numerous new species in threatened cloud forest
(01/14/2010) An expedition into rainforests on Ecuador's coast by Reptile & Amphibian Ecology International (RAEI) have revealed a number of possible new species including a blunt-snouted, slug-eating snake; four stick insects; and up to 30 new 'rain' frogs. The blunt-snouted snake, which feeds on gastropods like slugs, is especially interesting, as its closest relative is in Peru, 350 miles away. In addition, a fifteen-year-old volunteer with the organization found a snake that specializes on snails. The researchers are unsure of this is a new species: the closest similar snake is 600 miles away in Panama.
World of Avatar: in real life
(01/13/2010) A number of media outlets are reporting a new type of depression: you could call it the Avatar blues. Some people seeing the new blockbuster film report becoming depressed afterwards because the world of Avatar, sporting six-legged creatures, flying lizards, and glowing organisms, is not real. Yet, to director James Cameron's credit, the alien world of Pandora is based on our own biological paradise—Earth. The wonders of Avatar are all around us, you just have to know where to look.
Gone: a look at extinction over the past decade
(01/03/2010) No one can say with any certainty how many species went extinct from 2000-2009. Because no one knows if the world's species number 3 million or 30 million, it is impossible to guess how many known species—let alone unknown—may have vanished recently. Species in tropical forests and the world's oceans are notoriously under-surveyed leaving gaping holes where species can vanish taking all of their secrets—even knowledge of their existence—with them.
Not just the polar bear: ten American species that are feeling the heat from global warming
(12/01/2009) A new report, America’s Hottest Species, highlights a variety of American wildlife that are currently threatened by climate change from a small bird to a coral reef to the world’s largest marine turtle.
Kihansi spray toad goes extinct in the wild
(11/04/2009) This year's IUCN Red List has updated its assessment of the Kihansi spray toad, moving the species from Critically Endangered to Extinct in the Wild. With that another amphibian species has been lost to a combination of habitat loss and the devastating amphibian disease, the chytrid fungus. The Kihansi spray toad Nectophrynoides asperginis, which still survives in a number of zoos in the United States, had lived on just two hectares along the Kihansi gorge in Tanzania. The toad was specially adapted to the spray region of the Kihansi waterfall, which kept its small environment at a constant temperature and humidity.
New reserve created in Cambodia with REDD in mind
(10/26/2009) Cambodia's Royal Government's Council of Ministers has declared the creation of the Seima Protection Forest, a 1,100 square miles (2,849 square kilometers) park home to tigers, elephants, and endangered primates. The park's creation was developed in part by the Wildlife Conservation Society's (WCS) "Carbon for Conservation" program, which intends to protect high-biodiversity ecosystems while raising funds through carbon sequestration schemes such as Reducing Emission from Deforestation and Degradation (REDD).
Scientists uncover mystery of how frog plague kills its victims
(10/22/2009) One hundred and twenty species of frogs are reported to have gone extinct since 1980 (although the number is likely even higher). While devastated by habitat loss, pollution, and climate change, a baffling disease may be the biggest factor behind the alarming extinctions of frogs. Called chytridiomycosis, the disease is caused by the microscopic fungus Batrachochytrium dendrobatidis which kills its tiny victims indiscriminately.
Freshwater species worse off than land or marine
(10/15/2009) Scientists have announced that freshwater species are likely the most threatened on earth. Extinction rates for freshwater inhabitants are currently four to six times the rates for terrestrial and marine species. Yet, these figures have not lead to action on the ground.
Innovative reforestation project threatened by 'regime change' in Madagascar, an interview with Rainer Dolch
(09/16/2009) In Madagascar the TAMS Program (Tetik'asa Mampody Savoka, meaning "the project to bring back the forest") is under threat due to the new government's unwillingness to provide funding. The current government, after gaining power in a coup this year, has frozen all funds slated for the project and has yet to sign a carbon credit agreement with the World Bank which would bring much needed funding. "It remains to be seen if the recognition or not of Madagascar's transitional Government will lead to signing the contract with the World Bank in the near future. This is of course essential for the continuity of the project and its future," Rainer Dolch told Monagaby.com in an interview.
South Korea's frogs have avoided amphibian crisis so far, an interview with Pierre Fidenci
(09/09/2009) Frogs are on the edge. Blasted by habitat loss, pollution, and a terrible disease, the chytrid fungus, species are vanishing worldwide and those that remain are clinging to existence, rather than thriving. However, an interview with Pierre Fidenci, President of Endangered Species International (ESI), proves that there are still areas of the world where amphibians remain in abundance. South Korea is not a country that is talked about frequently in conservation circles. Other nations in the region attract far more attention, such as Malaysia and Indonesia. But it was just this neglect that drove Pierre Fidenci to visit the nation and survey the amphibians there.
New species everywhere in Papua New Guinea's 'lost' volcano
(09/07/2009) A five week expedition into a remote extinct volcano has uncovered a treasure trove of new species in Papua New Guinea, including what may be the world's largest rat, a fanged frog, and a grunting fish. In all the expedition estimates it may have found around forty species unknown to science. The expedition was undertaken by a BBC film crew and scientists in January. Local trackers led them into the unexplored jungle, hidden beneath the Bosavi volcano's 2,800 meter summit. Six months prior to arrival, fields of spinach and sweet potato were planted to feed the expedition in such a remote area.
Save the frogs, save ourselves
(09/04/2009) Amphibians are going extinct around the globe. As a scientist specializing in frogs, I have watched dozens of species of these creatures die out. The extinction of frogs and salamanders might seem unimportant, but the reality couldn't be farther from the truth. Indeed, from regulating their local ecosystems, to consuming and controlling the population of mosquitoes and other insects that spread disease, to potentially pointing the way to new drugs for fighting diseases such as cancer or HIV-AIDS, the fate of these creatures is inexorably linked to our own.
Pesticide use linked to dying frogs in California
(08/13/2009) Pesticides used by farmers in California's Central Valley could be killing frogs in the Sierra mountains, report researchers.
Photos: hundreds of new species discovered in Himalayan region, threatened by climate change
(08/10/2009) Scientists from a variety of organizations have found over 350 new species in the Eastern Himalayas, including a flying frog, the world’s smallest deer, and a gecko which has walked the earth for 100-million-years, according to a new report by the World Wildlife Fund (WWF). The report, entitled Where World’s Collide, warns that these rare biological treasures, as well as numerous other species, are threatened in the Eastern Himalayas by climate change.
Photo: Salamander is first 4-legged animal discovered in U.S. in 50 years
(07/09/2009) Researchers have discovered one of the world's smallest salamanders in a road-side creek in Georgia. The amphibian is so unique that it represents the first new genus of four-legged animal discovered in the United States in 50 years.
Photos: treasure trove of new species discovered in Ecuador
(06/16/2009) Near the once-contentious border of Ecuador and Peru in the mountainous forests of the Cordillera del Condor, scientists from Conservation International (CI) conducted a Rapid Assessment Program (RAP), uncovering what they believe are several new species, including four amphibians, one lizard, and seven insects. The team focused on the Upper Nanharitza River Basin, which has been geologically isolated from the rest of the Andes, giving it broad potential for new species.
Frogs species discovered living in elephant dung
(06/10/2009) Three different species of frogs have been discovered living in the dung of the Asian elephant in southeastern Sri Lanka. The discovery—the first time anyone has recorded frogs living in elephant droppings—has widespread conservation implications both for frogs and Asian elephants, which are in decline. "I found the frogs fortuitously during a field study about seed dispersal by elephants," Ahimsa Campos-Arceiz, a research fellow from the University of Tokyo, told Monagaby.com.
Approximately 200 new frogs discovered in Madagascar threatened by political instability
(05/11/2009) Amid the amphibian extinction crisis—where amphibians worldwide are disappearing due to habitat loss, pollution, and a devastating fungal epidemic—the Spanish Scientific Research Council (CSIC) has announced some good news. In a survey of the island-nation of Madagascar they have identified between 129 and 221 new species of frogs. The discovery of so many new species nearly doubles the island’s total number of frogs.
The story of ‘Save the Frogs Day’, April 28th, An Interview with Kerry Kriger
(04/26/2009) Founder and director of SAVE THE FROGS!, Dr. Kerry Kriger is responsible for the first annual Save The Frogs Day on Tuesday, April 28th with events planned worldwide from the United States to Nepal, and Australia to China. “I’m continually amazed at the positive response it’s gotten. I thought of Save The Frogs Day one night last December when I was the only full-time SAVE THE FROGS! employee and I only had a couple part-time volunteers,” Kriger explains.
