Frog plague found in India
(01/03/2012) 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.
New site is a match-maker for world's endangered frogs
(11/03/2011) A new initiative by the conservation group, Amphibian Ark, hopes to match lonely, vanishing frogs with a prince/princess to to save them. Dubbed FrogMatchMaker.com after online dating sites, the program is working to connect supporters and donors with amphibian conservation programs in need. Currently, amphibians are among the world's most imperiled species with 41 percent threatened with extinction according to the IUCN Red list.
Bat-killing culprit identified by scientists
(10/31/2011) First identified in 2005, white-nose syndrome has killed over a million bats in the US, pushing once common species to the edge of collapse and imperiling already-endangered species. Striking when bats hibernate, the disease leaves a white dust on the bat's muzzle, causing them to starve to death. Long believed to be caused by a fungus in the genus Geomyces, researchers publishing in Nature have confirmed that the disease is produced by the species, Geomyces destructans.
Isolated indigenous people and tourists collide in Peru park
(10/19/2011) New video released by the Peruvian government shows a potentially disastrous encounter between tourists and indigenous people long isolated from the outside world. In a motor boat tourists follow a group of Mashco-Piro people walking along the shores of the Manu River in Manu National Park. At one point one of the tribal members prepares to fire at the boat with an arrow. But danger doesn't only come from the possibility of a violent clash: uncontacted indigenous people, those who have chosen isolation from the world, are incredibly susceptible to disease.
Scientists find frog genes that provide immunity to extinction plague
(09/27/2011) 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.
Amphibian-plague strikes frogs harder in pristine ecosystems
(05/31/2011) 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.
North America's tiniest turtle vanishing
(05/12/2011) Despite decades of conservation work, populations of North America's smallest turtle, the bog turtle (Glyptemys muhlenbergii), is continuing to decline. Habitat destruction, invasive plants, road-kill, and the illegal pet trade have all played a role in the bog turtle historic decline, but researchers are now reporting increased mortalities across bog turtle populations, bringing fears of disease or an as-yet-unnamed environmental issue.
Indigenous group claims Ecuadorian government complicit in 'genocide'
(04/06/2011) Ecuador's paramount indigenous organization has filed a legal complaint against the government, including President Rafael Correa, for allegedly participating in 'genocide' against indigenous people in the Amazon. The Confederation of Indigenous Nationalities of Ecuador (CONAIE) is arguing that expanding oil exploration and mining is imperiling the lives of uncontacted tribes that have chosen voluntary isolation known as the Tagaeri and the Tarmenane, reports the AFP.
The value of the little guy, an interview with Tyler Prize-winning entomologist May Berenbaum
(04/06/2011) May Berenbaum knows a thing or two about insects: in recognition of her lifelong work on the interactions between insects and plants, she has had a character on The X-Files named after her, received the Public Understanding of Science and Technology Award for her work in making science accessible to the public, and this year has been awarded the prestigious Tyler Environmental Prize. "Winning the Tyler Prize is an incredible honor—most of my scientific heroes have been Tyler Prize winners and I’m exceedingly grateful to be considered worthy of being included among their ranks," Berenbaum told mongabay.com in an interview. "The Prize is also tremendously enabling—because the money is unrestricted I can use it to carry out projects that have been difficult to fund."
Bats worth billions
(04/03/2011) US agriculture stands to lose billions in free ecosystem services from the often-feared and rarely respected humble bat. According to a recent study in Science bats in North America provide the US agricultural industry at least $3.7 billion and up to a staggering $53 billion a year by eating mounds of potentially pesky insects. Yet these bats, and their economic services, are under threat by a perplexing disease known as white-nose syndrome (WNS) and to a lesser extent wind turbines.
15 conservation issues to watch
(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.
Forgotten species: the plummeting cycad
(12/06/2010) I have a declarative statement to make: cycads are mind-blowing. You may ask, what is a cycad? And your questions wouldn't be a silly one. I doubt Animal Planet will ever replace its Shark Week with Cycad Week (perhaps the fact that it's 'animal' planet and not 'plant' planet gave that away); nor do I expect school children to run to see a cycad first thing when they arrive at the zoo, rushing past the polar bear and the chimpanzee; nor do I await a new children's book about a lonely little anthropomorphized cycad just looking for a friend. In the world of species-popularity, the cycad ranks pretty low. For one thing, it's a plant. For another thing, it doesn't produce lovely flowers. And for a final fact, it looks so much like a palm tree that most people probably wouldn't know it wasn't. Still, I declare the cycad to be mind-blowing.
Climate change to take the lives of 5 million by 2020, mostly children
(12/06/2010) A new report by humanitarian research organization DARA and the Climate Vulnerable Forum finds that if nations continue to fail at lowering greenhouse gas emissions, five million people—mostly children—are likely to die from climate change impacts over the next 10 years. The report, called the Climate Vulnerability Monitor, predicts, in addition, that by 2030, one million people every year will perish from climate change impacts. The dire predictions come as nations struggle at a UN Climate Summit in Mexico this week to come up with a coordinated response to climate change, although an agreement is not expected this year.
Epidemic hits Amazonian indigenous group
(10/31/2010) An epidemic, suspected to be malaria, has struck down dozens of people of the Yanomami tribe in the Venezuelan Amazon, reports the Associated Press. Leaders of the three impacted village told health workers that approximately 50 people have died so far, many of them children.
Monarch butterflies medicate their sick kids
(10/12/2010) A new study in Ecology Letters has discovered that monarch butterflies employ medicinal plants to treat their larva. Researchers found that certain species of milkweed, which the larva feed on, can reduce the threat of a sometime deadly parasite. However, even more surprising: "we have also found that infected female butterflies prefer to lay their eggs on plants that will make their offspring less sick, suggesting that monarchs have evolved the ability to medicate their offspring," says lead author Jaap de Roode.
Losing nature's medicine cabinet
(10/04/2010) In all the discussions of saving the world's biodiversity from extinction, one point is often and surprisingly forgotten: the importance of the world's species in providing humankind with a multitude of life-saving medicines so far, as well as the certainty that more vital medications are out there if only we save the unheralded animals and plants that contain cures unknown. Already, species have provided humankind everything from quinine to aspirin, from morphine to numerous cancer and HIV-fighting drugs. "As the ethnobotanist Dr. Mark Plotkin commented, the history of medicine can be written in terms of its reliance on and utilization of natural products," physician Christopher Herndon told mongabay.com. Herndon is co-author of a recent paper in the journal Biotropica, which calls for policy-makers and the public to recognize how biodiversity underpins not only ecosystems, but medicine.
The true cost of the Commonwealth Games
(09/30/2010) UK newspapers have been flooded this week and last by reports of the Commonwealth Games' venue literally caving in and collapsing, athletes have deemed their village accommodation "filthy" and terrorists have apparently threatened attacks. Thanks to the late monsoon this year, floods are now a fear, and the Games' venue has been choked by a cloud of toxic insect repellent due to further fears of an outbreak of the potentially fatal dengue fever because of mosquitoes being drawn to the floods’ stagnant water.
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.
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).
Mahogany market in US threatening the lives of uncontacted natives in the Amazon
(07/20/2010) Consumers in the US purchasing mahogany furniture may be unwittingly supporting illegal logging in a Peruvian reserve for uncontacted indigenous tribes, imperiling the indigenous peoples' lives. A new report by the Upper Amazon Conservancy (UAC) provides evidence that loggers are illegally felling mahogany trees in the Murunahua Reserve where it is estimated some 200 uncontacted natives live.
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.
Malaria increases 50 percent following deforestation in the Amazon
(06/16/2010) A new study shows that deforestation in the Amazon helps spread disease by creating an optimal environment for malaria-carrying mosquitoes. The study, published in the online issue of the CDC journal Emerging Infectious Diseases, found that clearing forests in the Brazilian Amazon raised incidences of malaria by almost 50 percent.
Australian rainforest plant yields possible cancer killer
(06/14/2010) A drug derived from a plant native to the Australian rainforest may prove to be a new weapon against cancer, according to the AFP. QBiotics Ltd has released a statement announcing that a drug made from the seeds of a rainforest shrub has successfully treated tumors in over 150 animals, and the company is now preparing to test the drug on humans.
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.
When it comes to Yellow Fever, conserving howler monkeys saves lives
(03/29/2010) Abundant and diverse wildlife help people in many ways: for example bees pollinate plants, birds and mammals disperse seeds, bats control pest populations, and both plants and animals have produced life-saving medicines and technological advances. But how could howler monkeys save people from a Yellow Fever outbreak? A new study in the open-access journal Tropical Conservation Science explores the link between howler monkeys, mosquitoes, and humans during a recent yellow fever outbreak in the state of Rio Grande do Sul, Brazil.
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.
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."
Photos: ten beloved species threatened by global warming
(12/14/2009) The International Union for the Conservation of Nature (IUCN) has released a list of ten species that are likely to be among the hardest hit by climate change, including beloved species such as the leatherback sea turtle, the koala, the emperor penguin, the clownfish, and the beluga whale. The timing of the list coincides with the negotiations by world leaders at the UN Climate Change Conference to come up with an international agreement to combat climate change.
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.
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.
Saving gorillas by bringing healthcare to local people in Uganda, an interview with Dr. Gladys Kalema-Zikusoka
(09/16/2009) How can bringing healthcare to local villagers in Uganda help save the Critically Endangered mountain gorilla? The answer lies in our genetics, says Dr. Gladys Kalema-Zikusoka, wildlife veterinarian and director of Conservation through Public Health (CTPH). "Because we share 98.4% genetic material with gorillas we can easily transmit diseases to each other." Therefore, explains Kalema-Zikusoka "our efforts to protect the gorillas will always be undermined by the poor public health of the people who they share a habitat with. In order to effectively improve the health of the gorillas we needed to also improve the health of the people, which will not only directly reduced the health threat to gorillas through improvement of public health practices, but also improved community attitudes toward wildlife conservation."
Did malaria come from chimps?
(08/03/2009) Malaria may have jumped from chimpanzees to humans much like AIDS did, report researchers writing in Proceedings of the National Academy of Sciences.
Ebola virus found in pigs
(07/09/2009) A variant of the deadly Ebola virus has turned up in pigs in the Philippines, report researchers writing in the journal Science.
Research into drugs derived from natural products declining
(07/09/2009) Although the majority of drugs available today have been derived from natural products, research into nature-based pharmaceuticals has declined in recent years due to high development costs and the drug approvals process. However this trend is likely to reverse due to new approaches and technologies, according researchers from the University of Alberta.
Madfish?: scientist warns that farmed fish could be a source of mad cow disease
(06/17/2009) In a paper that shows just how strange our modern world has become, Robert P. Friedland, neurologist from the University of Louisville, warns that farmed fish could be at risk of Creutzfeldt Jakob disease, or mad cow disease.
The unknown role of coextinctions in the current extinction crisis
(05/28/2009) Scientists have long recognized ‘coextinctions’ as a major concern when it comes to the current mass extinction crisis. Despite such recognition, however, the role of coextinctions remains largely mysterious and little-studied. A new paper attempts to address this by settling what is known (and unknown) about the phenomenon of coextinctions and where research needs to go next.
After disease engulfs island, rare mountain chicken frogs airlifted to safety
(04/23/2009) In a rescue operation that sounds straight out of an action film, 50 mountain chicken frogs were airlifted from the Caribbean island Montserrat after the discovery of Chytridomycosis, a fungal disease that has wiped out amphibian populations worldwide. Already, hundreds of the critically-endangered mountain chicken frogs succumbed to the disease, which is thought to have made its way to the island in late 2008 or early 2009.
Howler monkeys poisoned because of misinformed link to yellow fever
(04/22/2009) There have been numerous reports of howler monkeys poisoned in the southernmost Brazilian state of Rio Grande do Sul due to misinformation regarding the monkeys and the yellow fever virus. Some locals believed that the monkeys, which also suffer from yellow fever, were in fact the disease-carriers, but yellow fever is carried by mosquitoes not monkeys. A new campaign headed by Dr. Julio Cesar Bicca Marques wants to set the record straight. The campaign, entitled ‘Save Our Guardian Angels’, is working to inform the public of the actual and important role of howler monkeys in yellow fever outbreaks.
Amphibians could develop immunity against devastating fungal disease
(04/03/2009) The fungal disease chytridiomycosis has ravaged amphibian populations, including contributing to several extinctions. But new research may bring some hope for currently threatened amphibians.
Flu epidemic killing bonobos in Congo sanctuary
(03/29/2009) Six bonobos, a species of chimpanzee, have died from a flu epidemic in a month at the Lola Ya Bonobo in the Democratic Republic of Congo (DRC). Ten more have contracted the flu. “There is no fever. Antibiotics don’t do anything. The bonobos have severe respiratory infections and then they can’t breath for 3 days then they die,” writes a staff member on the sanctuary's blog through the conservation organization WildlifeDirect. The staff of Lola Ya Bonobo have sent out a plea for help and donations, as the flu continues to sweep through their center.
'Stopgap’ to preserve US bats from devastating fungus
(03/05/2009) Half a million bats have succumbed to a mysterious fungal disease known as white-nose syndrome in two years. Found in seven states in the northeastern US, this syndrome has left biologists baffled since first discovered in 2006. While researchers are still trying to uncover the relationship of the syndrome to the bats, a recent study published in Frontiers in Ecology and the Environment e-View suggests a way to mitigate the syndrome devastating affect. Employing a mathematical simulation the researchers found that using localized heat sources on hibernating bats may preserve populations while a long-term solution is found.
Infecting mosquitoes with parasite could reduce dengue fever outbreaks
(01/05/2009) With an average of 50 million cases worldwide dengue fever is second only to malaria in terms of concern for mosquito-borne illnesses. Carried primarily by the mosquito species Aedes aegypti, the fever is usually not fatal; however a particular strain of disease can be especially dangerous to children. However, early this year new research brings hope to the tropical areas where dengue fever is prevalent. Scientists have discovered a new possibility in debilitating the mosquitoes carrying dengue fever: the Wolbachia parasite.
A cure for the Tasmanian devil's strange and fatal cancer?
(11/21/2008) Researchers have announced that two Tasmanian devils have survived a cancer devastating their species after receiving inoculations of dead tumor cells, according to the International Herald. However, the inoculations have not worked on every devil – despite being inoculated four devils died from the cancer during the work.
Previously unknown fungus may have triggered mass bat die-offs in the U.S.
(10/30/2008) Researchers have identified the fungus that may have been the culprit in mass dief-offs of bats in the northeastern United States during the winter of 2006-2007. The research is published in this week's issue of Science.
Does logging contribute to AIDS deaths in Africa?
(06/14/2008) Logging activities in tropical Africa may pose hidden health risks to wildlife and humans according to a veterinary pathobiologist speaking at a scientific conference in Paramaribo, Suriname.
Global warming could worsen HIV/AIDS epidemic
(04/30/2008) A number of studies have suggested that climate change could expand the range of tropical diseases like Dengue fever and Encephalitis. Now a researcher from the University of New South Wales (UNSW) in Australia says that global warming could lead to an increase in HIV infection rates worldwide.
Illegal wildlife trade worth $20B/yr
(03/19/2008) The illegal wildlife trade generates $5 to $20 billion annually, making it the largest illicit market after guns and drugs trafficking, reports a study released by the Congressional Research Service.
DEET repellent works by blocking human odor from mosquitoes
(03/13/2008) DEET, a potent insect repellent, works by blocking the aroma of human sweat, report researchers writing in the journal Science. The discovery could lead to the development of new repellents that have fewer health risks.
Global malaria map released - 35% of humanity at risk
(02/25/2008) Researchers have developed a spatial distribution map for malaria. The results are published in Public Library of Science (PLoS) Medicine.
