(01/16/2013) Last year scientists released a study that is likely to revolutionize how conservationists track elusive species. Researchers extracted the recently sucked blood of terrestrial leeches in Vietnam's remote Annamite Mountains and looked at the DNA of what they'd been feeding on: remarkably researchers were able to identify a number of endangered and rarely-seen mammals. In fact two of the species gleaned from these blood-meals had been discovered by scientists as late as the 1990s. In the past, trying to find rare and shy jungle animals required many man hours and a lot of funding. While the increasing use of remote camera traps has allowed scientists to expand their search, DNA sampling from leeches could be the next big step in simplifying (and cheapening) the quest for tracking the world's mammals.
Cute animal picture of the day: white-cheeked gibbon baby
(01/16/2013) A northern white-cheeked gibbon pair (Nomascus leucogenys) at the Wildlife Conservation Society's (WCS) Bronx Zoo have given birth to a brand new infant. This is the mother gibbon's 11th infant.
The secret to the surging popularity of sloths: viral Web videos
(01/16/2013) Sloths have been the beneficiary of a surge of popularity of late. A big part of that has been filmmaker Lucy Cooke's footage of baby sloths at the world's only sloth orphanage in Costa Rica. Posted on the Internet in 2010, a 90-second clip went viral and has now been watched millions of times. That video, called ‘Meet the Sloths’, 'attracted celebrity fans from Ricky Gervaise to Ashton Kutcher and turned the sleepy residents of the world’s only sloth orphanage into international superstars,' according to Cooke.
How a text message could save an elephant or a rhino from a poacher
(01/15/2013) Soon a text message may save an elephant's or rhino's life. The Kenya Wildlife Service (KWS) is implementing a new alarm system in some protected areas that will alert rangers of intruders via a text message, reports the Guardian. Elephants and rhinos have been killed in record numbers across Africa as demand for illegal rhino horns and ivory in Asia has skyrocketed.
Landmines, chains, and hope: the elephants of Thailand
(01/15/2013) Few animals draw more compassion and awe from people than elephants. Highly intelligent, deeply social, and touchingly sensitive, elephants have much in common with human beings, despite their size and shape. Yet elephants around the world are still often abused and mis-treated, whether to entertain tourists or as victims of human strife. A new film, The Last Elephants in Thailand, sets out to document both the good and bad that elephants encounter in a world dominated by homo sapiens.
In the kingdom of the black panther
(01/15/2013) The black panther has a mythical aura: Rudyard Kipling chose the animal for one of his heroes in the Jungle Book, in the 1970s it became the symbol of an African-American socialist party, while comic guru Stan Lee selected the stunning feline for his first black superhero. But the real black panther isn't an actual species, instead it's a rare dark pigmentation found most commonly in leopards, but also occasionally in jaguars and other wild cats. The rarity of the black panther—not to mention its striking appearance—has added to their mystery. However, recent studies have found that black panthers, in this case 'black leopards,' are astoundingly common in one part of the world: the Malayan peninsula.
Saving the Arabian leopard, the world's smallest leopard
(01/14/2013) Today most people are more likely to associate Yemen with warfare and bizarre terrorism plots rather than wildlife. But Yemen is home to a surprising diversity of animals, including a population of the world's smallest leopard: The Arabian leopard (Panthera pardus nimr). Native to the Arabian Peninsula, the Arabian leopard is today extremely rare — less than 200 animals are thought to survive in the wild. Despite the cat's precarious position, there is relatively little local enthusiasm to protect a species that is widely seen as a threat to livestock. Nevertheless one man in Yemen is trying to boost the value of leopard in the eyes of local people. David Stanton, an American teacher living in Yemen, had devoted his life to saving the Arabian leopard.
Kenya suffers it worst elephant poaching incident yet
(01/08/2013) Over the weekend Kenya suffered its single worst elephant poaching incident when poachers killed an entire family of elephants. In all, eleven elephants were gunned down and had their tusks removed. Among the dead was a two-month-old calf. The elephants were killed in Tsavo East National Park.
Environment ministry drops copper mine in Zambezi park
(01/07/2013) A proposed copper mine set to be built in Lower Zambezi National Park has been rejected by Zambia's environmental management agency. Australian company Zambezi Resources Ltd, a subsidiary of Proactive Investors, had scheduled the $494 million Kangaluwi Copper Project to begin production in 2015. But their proposal sparked an outcry from environmentalists and government lobbyists concerned about the effects of the open pit mine in the park. Though mining is not generally permitted in the park, Zambezi Resources obtained a Large-Scale Mining License from the government which would have allowed them to mine for 25 years right in the middle of Lower Zambezi National Park.
Animals of the Masai Mara - book review
(01/06/2013) Animals of the Masai Mara is the first illustrated guidebook to the Masai Mara region along the Kenya and Tanzania border. This is the world famous region of wildebeest migrations, large felines, towering African elephants, fascinating cultures, and great flora and fauna diversity. This is the guidebook for every child, and child inside of us, between the ages of 5 and 105 that has ever dreamt of learning about the fascinating animals seen on a safari in Africa.
An avalanche of decline: snow leopard populations are plummeting
(01/03/2013) The trading of big cat pelts is nothing new, but recent demand for snow leopard pelts and taxidermy mounts has added a new commodity to the illegal trade in wildlife products, according to the Environmental Investigation Agency (EIA). Traditionally, the market for large cat products has centered around tiger bones and parts for traditional Chinese medicine. Snow leopards (Uncia uncia), however, are a novel trend in the illegal wildlife trade arena and skins and taxidermy mounts are the most recent fad in luxury home décor.
Scientists: bizarre mammal could still roam Australia
(01/03/2013) The continent of Australia is home to a wide variety of wonderfully weird mammals—kangaroos, wombats, and koalas among many others. But the re-discovery of a specimen over a hundred years old raises new hopes that Australia could harbor another wonderful mammal. Examining museum specimens collected in western Australia in 1901, contemporary mammalogist Kristofer Helgen discovered a western long-beaked echidna (Zaglossus bruijnii). The surprise: long-beaked echidnas were supposed to have gone extinct in Australia thousands of years ago.
New species of cute, but venomous, primate discovered in Borneo
(12/13/2012) Researchers have described a new species of slow loris, a type of primate that is imperiled by the pet trade.
New inroads made into bushmeat consumption in Tanzania
(12/10/2012) Bushmeat consumption, or "wildlife hunted for human consumption," poses a significant threat to wildlife conservation all across the globe. But in Eastern Africa—where savannah grasslands flourish and big game roam free within 'protected' reserves—one may be forgiven to think that poaching does not occur here: but it does.
Vanishing corridors: trying to keep big animals on the move across Tanzania
(12/10/2012) One of the biggest challenges for big African wildlife like lions, elephants, and buffalo is movement across native habitat that is increasingly being encroached on by humans. Animals find their movement restricted by roads, fences, and property boundaries which fragment the landscape. Without safe, smart, and well-maintained corridors between designated wildlife areas, animals can get cut off from resources needed for survival and from potential mates (putting genetic health at risk), even while conflicts with humans become more frequent.
A new method to monitor stray dog abundance
(12/10/2012) Free-roaming dogs (Canis familiaris) can fill a variety of ecological roles including competitor, predator, prey, and transmitter of disease to both wildlife and people with particular concern for rabies. A range of methods has been used to control dog populations, but monitoring dogs is a critical part of assessing the effectiveness of these methods.
Lion population falls 68 percent in 50 years
(12/04/2012) African lions, one of the most iconic species on the planet, are in rapid decline. According to a new study in Biodiversity Conservation, the African lion (Panthera leo leo) population has dropped from around 100,000 animals just fifty years ago to as few as 32,000 today. The study, which used high resolution satellite imagery to study savannah ecosystems across Africa, also found that lion habitat had plunged by 75 percent.
Pledge to end wildlife trafficking for Wildlife Conservation Day
(12/04/2012) Today has been dubbed the first ever global Wildlife Conservation Day. To honor it, a coalition of conservation groups—including WWF and Wildlife Conservation Society (WCS)—are working to raise awareness of illegal wildlife trafficking. Poaching for traditional medicine, bushmeat, and other products has put innumerable species at risk, including tigers, rhinos, sharks, and elephants.
Despite small brains, gray mouse lemurs use calls to avoid inbreeding
(12/03/2012) As a small-brained and largely solitary primate, the gray mouse lemur (Microcebus murinus) wasn't supposed to have the capacity to distinguish the calls of its kin calls from other lemurs. However, a new study in BMC Ecology, finds that a female gray mouse lemur is able to determine the mating calls of its father, allowing it avoid inbreeding. The discovery challenges the long-held belief that only large-brained, highly social animal are capable of determining kin from calls.
New Guinea singing dog photographed in the wild for the first time
(12/03/2012) A rarely seen canine has been photographed in the wild, likely for the first time. Tom Hewitt, director of Adventure Alternative Borneo, photographed the New Guinea singing dog during a 12-day expedition up a remote mountain in Indonesian Papua. Very closely related to the Australian dingo, the New Guinea singing dog, so named for its unique vocalizations, has become hugely threatened by hybridization with domesticated dogs.
Reduction in snow threatens Arctic seals
(11/28/2012) Arctic snowfall accumulation plays a critical role in ringed seal breeding, but may be at risk due to climate change, according to a new study in Geophysical Research Letters. Sea ice, which is disappearing at an alarming rate, provides a crucial platform for the deep snow seals need to reproduce. Ringed seals (Phoca hispida) require snow depths of at least 20 centimeters (8 inches): deep enough to form drifts that seals use as birth chambers.
Photos: Chinese leopard wins camera trap contest
(11/27/2012) The third annual BBC Wildlife Magazine Camera Trap Photo of the Year contest has produced some stunning and surprising images, including a snow leopard sticking its tongue out, a rare giant pangolin, and wrestling monitor lizards. But the winner this year was the perfect shot of a young leopard in China.
Endangered muriqui monkeys in Brazil full of surprises
(11/26/2012) On paper, the northern muriquis (Brachyteles hypoxanthus) look like a conservation comeback story. Three decades ago, only 60 of the gentle, tree-dwelling primates lived in a fragment of the Atlantic Forest along the eastern coast of Brazil. Now there are more than 300. But numbers don’t tell the whole story, according to anthropologist Karen Strier and theoretical ecologist Anthony Ives of the University of Wisconsin, Madison. The pair analyzed 28 years of data on the demographics of the muriquis, one of the longest studies of its kind. They found surprising patterns about birth and death rates, sex ratios, and even how often the monkeys venture out of their trees. These findings raise questions about the muriquis’ long-term survival and how best to protect them, the scientists wrote in the Sept 17 issue of PLoS ONE.
Wolves, mole rats, and nyala: the struggle to conserve Ethiopia's highlands
(11/20/2012) There is a place in the world where wolves live almost entirely off mountain rodents, lions dwell in forests, and freshwater rolls downstream to 12 million people, but the place—Ethiopia's Bale Mountains National Park—remains imperiled by a lack of legal boundaries and encroachment by a growing human population. "Much of the land in Africa above 3,000 meters has been altered or degraded to the point where it isn’t able to perform most of the ecosystem functions that it is designed to do. Bale, although under threat and already impacted to a degree by anthropogenic activities, is still able to perform its most important ecosystem functions, and as such ranks among only a handful of representative alpine ecosystems in Africa."
Great apes suffer mid-life crisis too
(11/19/2012) Homo sapiens are not alone in experiencing a dip in happiness during middle age (often referred to as a mid-life crisis) since great apes suffer the same according to new research in the Proceedings of the National Academy of Sciences (PNAS). A new study of over 500 great apes (336 chimpanzees and 172 orangutans) found that well-being patterns in primates are similar to those experience by humans. This doesn't mean that middle age apes seek out the sportiest trees or hit-on younger apes inappropriately, but rather that their well-being starts high in youth, dips in middle age, and rises again in old age.
Hong Kong authorities intercept shipment with 200 dead elephants' worth of ivory
(11/18/2012) Officials in Hong Kong have made a second major ivory bust in less than a month, reports the Associated Press.
Bats face new perils from climate change
(11/15/2012) Global climate change could devastate bat populations around the world, threatening to tear yet another thread from the tapestry of biodiversity should current temperature trends persist, according to a new study. "Bats were the focus for this study because they are relatively understudied but due to their sensitivity to environmental stress, they are excellent indicators of climate change," Hayley Ann Sherwin, co-author of the paper published in Mammal Review, with the Queen University in Belfast, told mongabay.com.
Controversial wolf hunt moves to the Midwest, 196 wolves killed to date
(11/14/2012) The hugely controversial wolf hunt in the U.S. has spread from the western U.S. (Montana, Idaho, and Wyoming) to the Midwest (Minnesota and Wisconsin) this year. Although the wolf hunt is less than a month old in the region—and only eleven days old in Minnesota—196 animals so far have been shot. As in the west, the wolf hunt has raised hackles among environmentalists along with fierce defenders among hunters. Wolves, which were protected under the the Endangered Species Act (ESA) since 1973, were stripped of that status by legislation in 2009, opening the door—should a state choose—to trophy hunting.
Mountain gorilla population up by over 20 percent in five years
(11/13/2012) A mountain gorilla census in Uganda's Bwindi Impenetrable National Park has a population that continues to rise, hitting 400 animals. The new census in Bwindi means the total population of mountain gorillas (Gorilla beringei beringei) has reached 880—up from 720 in 2007—and marking a growth of about 4 percent per year.
Borneo may lose half its orangutans to deforestation, hunting, and plantations
(11/13/2012) Borneo will likely lose half of its orangutans if current deforestation and forest conversion trends continue, warns a comprehensive new assessment by an international team of researchers. The study, published in the journal PLoS ONE, overlays orangutan distribution with land use regulations in Malaysian and Indonesian Borneo. Borneo has suffered high rates of deforestation, logging, and forest conversion for industrial plantations in recent decades, endangering the world's largest surviving populations of orangutans.
Greater bamboo lemur removed from 'most endangered primates' list
(11/13/2012) Madagascar's greater bamboo lemur has been removed from the list of the world's 25 most endangered primates after conservationists discovered previously unknown populations of the rare creature, according to the Aspinall Foundation, a charity that set in motion a species survival plan for the lemur.
Cute animal picture of the day: baby giraffe
(11/12/2012) Reticulated giraffes (Giraffa camelopardalis reticulata), one of nine subspecies, are found in Somalia, Kenya, and Ethiopia. The world's tallest land animal, giraffes can stand as high as 5–6 meters (16–20 feet).
Development halted in crucial wildlife corridor in Malaysia
(11/07/2012) Kenyir Wildlife Corridor in northeast Malaysia is teeming with wildlife: elephants, gibbons, tigers, tapirs, and even black panthers (melanistic leopards) have been recorded in the 60 kilometer (37 mile) stretch of forest. In fact, researchers have recorded over 40 mammal species (see species list below), including 15 threatened with extinction according to the IUCN Red List. When these findings were presented by scientists to the Terengganu state government action followed quickly: all development projects have been halted pending a government study.
Over 100,000 farmers squatting in Sumatran park to grow coffee
(11/06/2012) Sumatra's Bukit Barisan Selatan National Park—home to the Critically Endangered Sumatran rhinos, tigers, and elephants—has become overrun with coffee farmers, loggers, and opportunists according to a new paper in Conservation and Society. An issue facing the park for decades, the study attempted for the first time to determine the number of squatters either living in or farming off Bukit Barisan Selatan National Park, a UNESCO World Heritage Site; the rough census—over 100,000 people—shocked scientists.
Whale only known from bones washes up on beach in New Zealand
(11/05/2012) In 2010, a whale mother and male calf were found dead on Opape Beach in New Zealand. Although clearly in the beaked whale family—the most mysterious marine mammal family—scientists thought the pair were relatively well-known Gray's beaked whales (Mesoplodon grayi). That is until DNA findings told a shocking story: the mother and calf were actually spade-toothed beaked whales (Mesoplodon traversii), a species no one had ever seen before as anything more than a pile of bones.
'The ivory trade is like drug trafficking' (warning graphic images)
(11/05/2012) For the past five years, Spanish biologist Luis Arranz has been the director of Garamba National Park, in the Democratic Republic of Congo (DRC). Arranz and a team of nearly 240 people, 140 guards among them, work to protect a vast area of about 5,000 square kilometers (1,930 square miles) of virgin forest, home to a population of more than 2.300 elephants that are facing a new and more powerful enemy. The guards are encountering not only bigger groups of poachers, but with ever more sophisticated weapons. According to Arranz, armed groups such as the Lord’s Resistance Army from Uganda are now killing elephants for their ivory.
Leopard poaching is a bigger problem in India than previously believed
(10/31/2012) A recent study conducted by wildlife trade monitoring group TRAFFIC uncovered unnerving statistics about the illegal trade of leopards (Panthera pardus) in India: at least four leopards have been poached every week for the past decade in the country. The study, entitled Illuminating the Blind Spot: A study on illegal trade in Leopard parts in India, highlights the severity of leopard poaching from 2001 to 2010, despite preventative measures established in 1972 by the Wildlife Protection Act (WLPA) that prohibit the sale of leopard parts in India.
Illegal hunting threatens iconic animals across Africa's great savannas, especially predators
(10/25/2012) Bushmeat hunting has become a grave concern for species in West and Central Africa, but a new report notes that lesser-known illegal hunting in Africa's iconic savannas is also decimating some animals. Surprisingly, illegal hunting across eastern and southern Africa is hitting big predators particularly hard, such as cheetah, lion, leopard, and wild dog. Although rarely targets of hunters, these predators are running out of food due to overhunting and, in addition, often becoming victims of snares set out for other species.
By imitating human voices, beluga whale may have been attempting to communicate
(10/23/2012) Five years after the death of a captive beluga whale named NOC, researchers have discovered that the marine mammal may have been trying to communicate with people by mimicking humans voices at the National Marine Mammal Foundation in San Diego. Analyzing tapes of human-like speech from the young male beluga whale, scientists writing in Current Biology note that while there have been reports of beluga whales making human like sounds before, this is the first time evidence has been captured on tape and analyzed.
Authorities confiscate 600 dead elephants' worth of ivory in Hong Kong
(10/22/2012) Hong Kong authorities have confiscated two massive shipments of elephant tusks, totaling 1,209 tusks, stemming from Kenya and Tanzania. Representing over 600 poached elephants, the shipments are estimated to be worth $3.4 million on the black market. African elephants are being decimated for their tusks in recent years with heavily-armed and well-connected poachers—backed by criminal syndicates—killing off whole herds in some cases.
Cute animal picture of the day: baby pygmy hippo
(10/22/2012) A new pygmy hippo calf has been born at the Zoological Society of London (ZSL) Whipsnade Zoo. Named Georgina, the calf is the second for parents Flora and Tapon.
Rehabilitated orangutans in danger if industrial project proceeds in Borneo
(10/22/2012) The proposed extension of an industrial area in East Kalimantan, Indonesia will likely mean the end of a population of rehabilitated orangutans who reside there, according to the Indonesian environmental group Peduli Teluk Balikpapan. The Kariangau Industrial Area (KIK) will comprise 5,130 hectares of land currently covered by hardwood forests and mangroves when completed, including one third of orangutan habitat in Sungai Wain forest—a crucial portion that is not within the boundaries of the Sungai Wain Protection Forest and therefore not under any governmental protection.
South Africa hits another new record in rhino killings
(10/18/2012) Four hundred and fifty-five rhinos have been killed by poachers in South Africa since the beginning of the year. The number surpasses the record set last year (448) and proves that national efforts to stem poaching have not yet made a dent in actual killings. The mass killing has been spurred on by high demand for powdered rhino horn in Vietnam and China. A traditional curative in Asia, rhino horn has no medicinal properties according to scientists.
Picture of the day: the maned lioness
(10/15/2012) The title is not a typo. Sometimes lioness grow manes as rich and large as males, and there appears to be larger proportion of such 'maned lionesses' in Botswana's Okavango Delta.
The world's 25 most endangered primates: nearly a quarter in Madagascar
(10/15/2012) A coalition of conservation groups released the biannual Top 25 Primates list today, including nine species not appearing on the 2010 list, at the UN's Convention on Biological Diversity (CBD) in Hyderabad, India. Madagascar tops the list as home to the most threatened primates, including six on the list. Following Madagascar, Vietnam contains five, Indonesia three, and Brazil two. In all, over half (54 percent) of the world's primates, which have been evaluated, are considered threatened by the IUCN Red List.
The riot over rhinos: how a luxury and illegal commodity is driving the slaughter of one of the world’s iconic megafauna
(10/15/2012) 23,680 = the estimated number of wild rhinoceroses in South Africa. 35,000,000 = the number of American dollars generated by rhino hunting in South Africa. 97% = the percentage increase in illegally-hunted rhinos in 2011 from the national average in 1990. 30,000 = the number of pounds of rhino horns confiscated from poachers since 2010. 65 = the number of horns that have been stolen in South Africa from public display. 430...the number of rhinos killed this year, and counting...
Cute animal picture of the day: baby walruses on the mend
(10/11/2012) Two walrus male calves were discovered over the summer near Barrow, Alaska, dehydrated and ill, after their separate mothers perished. The calves have been receiving care at the Alaska SeaLife Center, but one will soon be moved to the Wildlife Conservation Society's (WCS) New York Aquarium and the other to the Indianapolis Zoo.
Dollar General drops APP due to rainforest destruction concerns
(10/11/2012) U.S. retailer Dollar General has stopped sourcing paper products from controversial brand Asia Pulp and Paper (APP), according to the World Wide Fund for Nature (WWF) which has targeted 20 companies for selling APP-sourced tissue and paper towels. APP has been under fire for years for deforestation on the Indonesian island of Sumatra, the last home to the Sumatran tiger (Panthera tigris sumatrae), Sumatran orangutan (Pongo abelii), and Sumatran elephant (Elephas maximus sumatranus), each of which is listed as Critically Endangered by the IUCN Red List.
Appreciating elephant individuality: a new approach to preventing conflicts with humans
(10/09/2012) To prevent conflicts between humans and elephants in developed areas, a new study shows there is much to learn from analyzing Asian elephant behavior at the individual level as opposed to population studies. Researchers have traditionally interpreted elephant behavior at the population level, looking for behavior patterns among elephants of similar ages, group sizes, and genders. Today, field researchers in India are studying elephant behavior at the individual level. Their goal is to appreciate the idiosyncrasies of individual elephants in the hopes of predicting their behavior. Nishant Srinivasaiah, of the Tata Institute of Fundamental Research and lead author of the study, told mongabay.com that it is vital "to get to know our elephants more intimately than ever before and, more importantly, to shift our focus from a population to include its individuals as well."
Cute animal picture of the day: red panda kits
(10/04/2012) Although called red pandas, these Asian animals are neither pandas nor bears, and despite a resemblance to raccoons they are not closely related to them either. Red pandas (Ailurus fulgens) are actually now thought to be the sole living representative of the taxonomic family, Ailuridae. The rest of their near-relatives are extinct, making red pandas a very important species.
