(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.
What types of primates are most prone to extinction in small forest fragments?
(12/06/2009) According to the most recent IUCN assessment, 48 percent of primates are threatened with extinction. Major threats to primates include habitat loss and fragmentation, hunting, and the wildlife trade. A new paper published in Tropical Conservation Science looked at ones of these threats — fragmentation — in an effort to determine what traits put primates at highest risk of extinction in forest fragments. Traits investigated all related to various aspects of primate biology, including: the amount of habitat needed, reproductive rate, and types of specialization. Surprisingly the authors, Matthew A. Gibbons and Alexander H. Harcourt of the University of California at Davis, found no significant relationship between extinction risk and any of the biological parameters.
Extinctions on the rise in the Galapagos: fishing and global warming devastating islands' species
(12/03/2009) We may never see again the Galapagos black-spotted damselfish, the beautiful 24-rayed sunstar, or the Galapagos stringweed. These species from Galapagos waters may all very well be extinct. Other species are on the brink, such as the Galapagos penguin and the Floreana cup coral. A new report in Global Change Biology reveals that in just a matter of decades, overfishing and climate change has devastated the Galapagos' unique and famous ecosystems.
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.
Face-to-face with what may be the last of the world's smallest rhino, the Bornean rhinoceros
(12/01/2009) Nothing can really prepare a person for coming face-to-face with what may be the last of a species. I had known for a week that I would be fortunate enough to meet Tam. I'd heard stories of his gentle demeanor, discussed his current situation with experts, and read everything I could find about this surprising individual. But still, walking up to the pen where Tam stood contentedly pulling leaves from the hands of a local ranger, hearing him snort and whistle, watching as he rattled the bars with his blunted horn, I felt like I was walking into a place I wasn't meant to be. As though I was treading on his, Tam's space: entering into a cool deep forest where mud wallows and shadows still linger. This was Tam's world; or at least it should be.
Zoos call for deeper emission cuts to save life on Earth
(11/30/2009) To save species around the world zoos say deeper emission cuts are needed than governments are currently proposing. Over 200 zoos worldwide have signed a petition calling on governments to set the target of atmospheric carbon below 350 parts per million (ppm) far lower than most government targets.
Extinct goat was "similar to crocodiles"
(11/16/2009) It sounds like something out of Greek mythology: a half-goat, half-reptilian creature. But researchers have discovered that an extinct species of goat, the Balearic Island cave goat or Myotragus balearicus, survived in nutrient-poor Mediterranean islands by evolving reptilian-specific characteristics. The goat, much like crocodiles, was able to grow at flexible rates, stopping growth entirely when food was scant. This adaptation—never before seen in a mammal—allowed the species to survive for five million years before being driven to extinction only 3,000 years ago, likely by human hunters.
DNA uncovers nearly extinct Siamese crocodiles in captivity
(11/15/2009) The Critically Endangered Siamese crocodile, once believed to be extinct in the wild, received some uplifting news this week. DNA testing of 69 rescued crocodiles at Phnom Tama Wildlife Rescue Center (PTWRC) in Cambodia found 35 purebred Siamese crocodiles.
Declaration calls for more wilderness protected areas to combat global warming
(11/11/2009) Meeting this week in Merida, Mexico, the 9th World Wilderness Congress (WILD9) has released a declaration that calls for increasing wilderness protections in an effort to mitigate climate change. The declaration, which is signed by a number of influential organizations, argues that wilderness areas—both terrestrial and marine—act as carbon sinks, while preserving biodiversity and vital ecosystem services.
Obama slower than Bush in protecting America's endangered species
(11/08/2009) In George W. Bush's eight years as president, he placed 62 species under the protection of the Endangered Species Act (ESA), an average of eight species per year. While, Bush's slow pace in protecting endangered species frustrated environmentalists in light of continued decline among many species, Obama is moving even slower.
Hunting across Southeast Asia weakens forests' survival, An interview with Richard Corlett
(11/08/2009) A large flying fox eats a fruit ingesting its seeds. Flying over the tropical forests it eventually deposits the seeds at the base of another tree far from the first. One of these seeds takes root, sprouts, and in thirty years time a new tree waits for another flying fox to spread its speed. In the Southeast Asian tropics an astounding 80 percent of seeds are spread not by wind, but by animals: birds, bats, rodents, even elephants. But in a region where animals of all shapes and sizes are being wiped out by uncontrolled hunting and poaching—what will the forests of the future look like? This is the question that has long occupied Richard Corlett, professor of biological science at the National University of Singapore.
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.
Reptiles underrepresented on the IUCN Red List
(11/04/2009) Currently there are an estimated nearly 9,000 reptiles in the world, while the International Union for Conservation of Nature (IUCN) Red List has assessed all of the world's described mammals, birds, and amphibians, reptiles have yet to be fully assessed, leaving herpetologists with an unclear picture of how reptiles are faring in the world. Currently, 1,677 reptiles have been assessed (less than 20 percent of the total number of reptile species known) with 293 added this year.
Governments, public failing to save world's species
(11/04/2009) According to the International Union for the Conservation of Nature's (IUCN) 2008 report, released yesterday, 36 percent of the total species evaluated by the organization are threatened with extinction. If one adds the species classified as Near Threatened, the percentage jumps to 44 percent—nearly half.
The Yangtze River may have lost another inhabitant: the Chinese paddlefish
(10/22/2009) In December of 2006 it was announced that the Yangtze River dolphin, commonly known as the baiji, had succumbed to extinction. The dolphin had survived on earth for 20 million years, but the species couldn't survive the combined onslaught of pollution, habitat loss, boat traffic, entanglement in fishing hooks, death from illegal electric fishing, and the construction of several massive dams. Now, another flagship species of the Yangtze River appears to have vanished.
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.
Logged forests support biodiversity after 15 years of rehabilitation, but not if turned into plantations
(10/21/2009) With the world facing global warming and a biodiversity crisis, a new study shows that within 15 years logged forests—considered by many to be 'degraded'—can be managed in order to successfully fight both climate change and extinction.
World's largest golden orb weaving spider discovered in South Africa and Madagascar
(10/21/2009) Golden orb weaving spiders have been garnering media attention recently. Last year stunning photographs of a golden orb weaver eating a bird in Australia made world coverage. Now, over a century after the last legitimate species of golden orb weaver was discovered, researchers have announced the discovery of a new and rare species of golden orb weaving spider in Africa and on the island of Madagascar. On average the new species is the largest of all golden orb weavers known.
Illegal ivory demand could wipe out Africa's elephants by 2025
(10/20/2009) Nearly twenty years ago the ivory trade was banned by Convention on International Trade in Endangered Species (CITES). Many saw this as the most important step in preventing the continued loss of elephants at the hands of poachers, and for awhile poaching slowed down. But now elephants are in danger again: a report by the International Fund for Wildlife Welfare (IFWW) states that an astounding 38,000 elephants are killed for their tusks annually—over a hundred every day.
Present day tropical plant families survived in warmer, wetter tropics 58 million years ago
(10/18/2009) Fifty eight million years ago the tropical rainforests of South America shared many similarities with today's Neotropical forests, according to research published in the Proceedings of the National Academy of Sciences. Looking at over 2,000 fossils in Colombia from one of the world's largest open pit coal mines, scientists were able to recreate for the first time the structure of a long vanished rainforest. One inhabited by a titanic snake, giant turtles, and crocodile-like reptiles.
Tiger success story turns bleak: poachers decimating great cats in Siberia
(10/18/2009) There were two bright spots in tiger conservation, India and Russia, but both have dimmed. Last year India announced that a new survey found only 1,411 tigers, instead of the previous estimation of 3,508, and now Russian tigers may be suffering a similar decline. The Siberian Tiger Monitoring Program—a collaboration between the Wildlife Conservation Society (WCS) and several Russia government organizations—has found evidence that after a decade of stability the Siberian tiger's population may be falling. This year's annual survey, which covers only a portion of tiger habitat in Russia, found only 56 adult tigers: a forty percent decrease from the average of 95 tigers. While the cause of this year's decline may be weather-related, researchers fear something far more insidious is going on.
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.
To save species conservationists must focus on conserving at least 5,000 individuals
(10/15/2009) The tiger has an estimated population of 3,400-5,000 individuals; the giant panda, 1,000-2,000; the North Atlantic right whale, 350-400; the Sumatran rhino, 250; and the California condor, 170. A new study shows that none of these species is safe from extinction yet, although each has received considerable conservation attention compared to most imperiled species.
Malayan tiger rescued from poacher's snare proves need for increased enforcement
(10/13/2009) Last week a Malayan tiger (Panthera tigris jacksoni) was found with its front right paw caught in a snare set by poachers. World Wildlife Fund’s (WWF) Wildlife Protection Unit discovered the snared tiger in the Belum-Temengor forest, a wildlife-rich reserve that has become a hotspot for poaching. After finding the wounded tiger the anti-poaching team called in officials from the Department of Wildlife and National Parks (PERHILITAN) who freed the great cat. The animal was then transported to Malacca Zoo for treatment.
Could agroforestry solve the biodiversity crisis and address poverty?, an interview with Shonil Bhagwat
(09/24/2009) With the world facing a variety of crises: climate change, food shortages, extreme poverty, and biodiversity loss, researchers are looking at ways to address more than one issue at once by revolutionizing sectors of society. One of the ideas is a transformation of agricultural practices from intensive chemical-dependent crops to mixing agriculture and forest, while relying on organic methods. The latter is known as agroforestry or land sharing—balancing the crop yields with biodiversity. Shonil Bhagwat, Director of MSc in Biodiversity, Conservation and Management at the School of Geography and the Environment, Oxford, believes this philosophy could help the world tackle some of its biggest problems.
Will tropical trees survive climate change?, an interview with Kenneth J. Feeley
(09/24/2009) One of the most pressing issues in the conservation today is how climate change will affect tropical ecosystems. The short answer is: we don't know. Because of this, more and more scientists are looking at the probable impacts of a warmer world on the Earth's most vibrant and biodiverse ecosystems. Kenneth J. Feeley, tropical ecologist and new professor at Florida International University and the Center for Tropical Plant Conservation at the Fairchild Tropical Botanic Garden, is conducting groundbreaking research in the tropical forests of Peru on the migration of tree species due to climate change.
Working to save the 'living dead' in the Atlantic Forest, an interview with Antonio Rossano Mendes Pontes
(09/23/2009) The Atlantic Forest may very well be the most imperiled tropical ecosystem in the world: it is estimated that seven percent (or less) of the original forest remains. Lining the coast of Brazil, what is left of the forest is largely patches and fragments that are hemmed in by metropolises and monocultures. Yet, some areas are worse than others, such as the Pernambuco Endemism Centre, a region in the northeast that has largely been ignored by scientists and conservation efforts. Here, 98 percent of the forest is gone, and 70 percent of what remains are patches measuring less than 10 hectares. Due to this fragmentation all large mammals have gone regionally extinct and the small mammals are described by Antonio Rossano Mendes Pontes, a professor and researcher at the Federal University of Pernambuco, as the 'living dead'.
On the edge of extinction, Fiji petrels observed at sea for the first time
(09/15/2009) The Critically Endangered Fiji petrel has been observed at sea for the first time by BirdLife International and NatureFiji-MareqetiViti. First recorded in 1855 from one specimen found on Gau Island, Fiji, the rare seabird disappeared from scientific view for 130 years. Beginning in 1984 a handful of 'grounded' Fiji petrels Pseudobulweria macgillivrayi were found after landing on village roofs in Gau, but this is the first observation of the bird in its element: at sea.
Rhino poaching epidemic underway in South Africa
(09/10/2009) In July national parks in South Africa lost 26 white rhinos and one black rhino to poachers, bringing the total rhinos lost to in South Africa to 84 this year alone. The situation has led Water and Environmental Affairs Minister Buyelwa Sonjica to call for an integrative approach to the crisis.
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.
Crowned sifaka population on the verge of local extinction: dispatch from the field
(09/08/2009) A small group of crowned sifaka lemurs Propithecus coronatus have been located in the corridor d’Amboloando-Dabolava, Miandrivazo district-Madagascar, but are immediately threatened with local extinction. The small, fragmented, and isolated forest shelters a group of only six adults and one baby. Interviews with local people revealed that once several groups of the species resided in the corridor, and even last year, about 20 individuals were still found there. However, within one year, the population dropped from 20 to 6 individuals.
Discovering nature's wonder in order to save it, an interview with Jaboury Ghazoul
(09/08/2009) Sometimes we lose sight of the forest by staring at the trees. When this happens we need something jarring and eloquent to pull us back to view the big picture again. This is what tropical ecologist Jaboury Ghazoul provided during a talk at the Association of Tropical Biology and Conservation (ATBC) meeting this summer in Marburg, Germany. Throwing out a dazzling array of big ideas and even bigger questions—incorporating natural history, biodiversity, morality, philosophy, and art—the enthusiastic Ghazoul left his audience in a state of wonder.
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.
Critically-endangered turtle seen in the wild for the first time by scientists
(09/03/2009) Scientists have stumbled on the Arakan forest turtle for the first time in the wild, according to a report by the Wildlife Conservation Society (WCS). One of the world's rarest turtles, the Arakan forest turtle was thought to be extinct for 86 years, before being discovered in an Asian food market in 1994. It has never before been observed in the wild by scientists. A team with WCS found five of the Critically Endangered turtles in a wildlife sanctuary in Myanmar (also known as Burma). The rarely-visited sanctuary was originally created to protect Asian elephants.
Investing in conservation could save global economy trillions of dollars annually
(09/03/2009) By investing billions in conserving natural areas now, governments could save trillions every year in ecosystem services, such as natural carbon sinks to fight climate change, according to a European report The Economics of Ecosystems and Biodiversity (TEEB).
Last chance to save a 'singular beauty' of Asia: the shy soala
(09/03/2009) Only discovered in 1992, the reclusive and beautiful saola Pseudoryx nghetinhensis may soon vanish from the Earth, if rapid action isn't taken to save one of Asia's most enigmatic and rare mammals. Listed as Critically Endangered, the species has experienced a sharp decline since its discovery due largely to poaching. "The animal's prominent white facial markings and long tapering horns lend it a singular beauty, and its reclusive habits in the wet forests of the Annamites an air of mystery," says Barney Long, of the IUCN Asian Wild Cattle Specialist Group.
World's rarest duck flies closer to extinction's edge
(08/27/2009) The Madagascar pochard, the world's rarest duck, was already thought to be extinct once. After a last sighting in 1991 the species was thought to have vanished until nine adults and four hatchlings were discovered in 2006. However, conservationists have begun to fear that the species will never recover after a survey this year found only six females.
World's largest bat threatened with extinction due to legal hunting
(08/25/2009) Under the current legal hunting rate scientists predict that the world's largest bat, the aptly-named large flying fox or Pteropus vampyrus, faces extinction in six to 81 years. Increasing the urgency to save the large flying fox is the vital role it plays as an ecosystem engineer (a species whose behavior can shape an ecosystem); the species maintains Southeast Asian forests by dispersing a wide variety of seeds over distances farther than most birds and other mammals.
Conservation group calls on birders to look for extinct species
(08/24/2009) The conservation group, Birdlife International, has called on birders around the world to keep an eye out for birds classified--some over a centruy ago--as extinct.
Economic crisis threatens conservation programs and endangered species, an interview with Paula Kahumbu of WildlifeDirect
(08/17/2009) Founded in 2004 by legendary conservationist Richard Leakey, WildlifeDirect is an innovative member of the conservation community. WildlifeDirect is really a meta-organization: it gathers together hundreds of conservation initiatives who blog regularly about the trials and joys of practicing on-the-ground conservation. From stories of gorillas reintroduced in the wild to tracking elephants in the Okavango Delta to saving sea turtles in Sumatra, WildlifeDirect provides the unique experience of actually hearing directly from scientists and conservationists worldwide.
Extinction debt can last millions of years
(07/29/2009) Extinction can be set in motion millions of years before a species' actual demise, suggesting that present-day drivers of habitat destruction and degradation may have already doomed many species to eventual extinction, report researchers writing in Proceedings of the Royal Society B online.
Extinction risk for Amazonian plants may be lower than previously estimated
(07/06/2009) Five to nine percent of the Amazon's 40,000 known species of plants will be at risk of extinction by 2050 should current deforestation trends continue, report researchers writing in the Proceedings of the National Academy of Sciences. The estimates are sharply lower than the 20 to 33 percent predicted in other studies.
869 species extinct, 17,000 threatened with extinction
(07/02/2009) Nearly 17,000 plant and animal species are known to be threatened with extinction, while more than 800 have disappeared over the past 500 years, reports the International Union for Conservation of Nature (IUCN). While these numbers are substantial, they are likely "gross" underestimates since only 2.7 percent of 1.8 million described species have been assessed. The IUCN report warns that governments will miss their 2010 target for reducing biodiversity loss.
Over 30 percent of open ocean sharks and rays face extinction
(06/25/2009) The first global study of open ocean (pelagic) sharks and rays found that 32 percent of the species are threatened with extinction largely due to overfishing and bycatch, making pelagic sharks and rays more threatened than birds (12 percent), mammals (20 percent), and even amphibians (31 percent), which are considered to be undergoing an extinction crisis. The situation worsens when only sharks taken in high-seas fisheries are considered: 52 percent of these species are threatened.
Saving tigers by counting feces
(06/24/2009) Scientists have been counting tiger populations for decades, using a variety of methods including camera traps and DNA collected from tissue or blood after darting and sedating the world’s largest cat. However, a new method of surveying tiger populations could change scientists’ ability to non-invasively obtain accurate numbers for tiger populations around the world, according to a study in Biological Conservation.
First comprehensive study of insect endangerment: ten percent of dragonflies threatened
(06/23/2009) A lot of time, effort, and funds have been spent on programs evaluating the threat of extinction to species around the world. Yet insects have not benefited from these programs, which have largely focused on more 'charismatic' species such as mammals, birds, amphibians, and reptiles. This gap is clearly shown by the fact that 42 percent of vertebrates have been assessed by the International Union for the Conservation of Nature (IUCN), and only 0.3 percent of invertebrates.
New Yangtze River dam could doom more endangered species
(06/22/2009) Eight Chinese environmentalists and scientists have composed a letter warning that a new dam under consideration for the Yangtze River could lead to the extinction of several endangered species. The letter contends that Xiaonanhia Dam, which would be 30 kilometers upstream from the city of Chongqing, will negatively impact the river’s only fish reserve. Spanning 400 kilometers in the upper Yangtze, the reserve is home to 180 fish species, including the Endangered Chinese sturgeon, and the Critically Endangered Chinese paddlefish, as well as the finless porpoise.
War and conservation in Cambodia
(06/21/2009) The decades-long conflict in Cambodia devastated not only the human population of the Southeast Asian country but its biodiversity as well. The conflict led to widespread declines of species in the once wildlife-rich nation while steering traditional society towards unsustainable hunting practices, resulting in a situation where wildlife is still in decline in Cambodia, according to a new study from researchers with the World Wildlife Fund (WWF).
Extinction of Christmas Island Pipistrelle bat predicted in less than six months
(06/03/2009) The Australasian Bat Society predicts that the Christmas Island Pipistrelle bat has less than six months left until extinction, unless measures are taken immediately to set-up a captive breeding population.
Migrations of large mammals in serious declines, six have vanished entirely
(06/03/2009) Watch any nature documentary and it’s sure to include pulse-pounding footage of large herbivores migrating across African plains, Asian steppe, or the Arctic tundra. The images have become iconic: wildebeest forging a crocodile-inhabited river, caribou breaking through snow fields, Saiga running over tall grass. Despite such images of plenty, migrations are declining across the world, and in six cases have disappeared entirely.
