Kihansi spray toad goes extinct in the wild

2009-11-04T22:03:00Z

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

2009-10-26T16:47:00Z

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

2009-10-22T18:06:00Z

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

2009-10-15T19:47:00Z

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

2009-09-16T22:39:00Z

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

2009-09-09T17:04:00Z

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

2009-09-07T21:42:00Z

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

2009-09-04T17:33:00Z

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.

Have Australian cane toads finally met their match?

2009-03-31T17:24:00Z

This weekend in Queensland, Australia the government held the first 'Toad Day Out' where hundreds of locals went hunting for the invasive cane toad, catching an estimated 10,000 toads to be euthanized. At the same time, researchers announced in the journal Functional Ecology that they may have discovered a native Australian species that will finally rout the cane toad—and it's not man. The meat ant is a notoriously aggressive and abundant insect which is known to consume anything edible, including the scientists argue, cane toads.

At 3,000 meters (9,842 feet) in the Andes herpetologists were surprised to discover a frog so small it could sit on a dime with room to spare. Further study showed that this new species, named Noble's pygmy frog, is the smallest frog in the Andean mountain range.

Poison frog diversity linked to the Andes

2009-03-10T16:26:00Z

Electric colors, wild markings, and toxic skin have made poison frogs well-known inhabitants of the Amazon rainforest. With 353 recognized species, and probably more awaiting discovery, poison frogs are an incredibly diverse group of amphibians. While it has long been believed that the Amazon basin, itself, was the source of their diversity, a new study published in PLoS Biology has uncovered that the Andes mountain chain has served as an oven of evolutionary biodiversity for poison frogs over several million years.

Symposium tackles big question: how many species will survive our generation

2009-01-16T17:17:00Z

Nine scientists dusted off their crystal balls Monday at the National Museum of Natural History in Washington DC, weighing in on the future of the world’s tropical forest. Despite the most up-to-date statistics, prognosis for the future of tropical forests varied widely. In the last few years a schism has occurred among biologists regarding the future of the tropics. No tropical scientist denies that rainforests and the species which inhabit them face unprecedented threats; neither do they argue that some of these forested regions and species will likely not survive the next fifty years. What has sparked debate, sometimes heated, is how bad will is it really? When the dust settles, what percentage of species will survive and how much forest will remain?

What is the greatest threat to rainforests: habitat destruction or climate change?
