(03/07/2014) One of the difficulties of studying rare and endangered species is that they are, by definition, hard to find. Scientists attempting to understand their distributions and the threats to their survival can spend hundreds of hours in the field while collecting little data, simply because sightings are so few and far between.
Rhino with bullet in its brain and hacked off horn wanders for days before being put down
(03/05/2014) Last week, visitors in Kruger National Park came on a horrifying sight of the poaching trade: a rhino, still alive, with its horn and part of its face chopped off. The gruesome photo of the young rhino went viral and sent South African authorities scrambling. Five days after the sighting, South African National Parks (SANParks) has announced they found the rhino and put it out of its misery.
Javan rhino population jumps by over 10 percent
(03/04/2014) The Javan rhino population has increased by over ten percent from 2012 to last year, according to new figures released by Ujung Kulon National Park. Using camera traps, rangers have counted a total of 58 Javan rhinos, up from 51 in 2012. Although the species once roamed much of Southeast Asia, today it is only found in Ujung Kulon National Park in western Javan and is known as one of the most imperiled mammals on the planet.
Palm oil plantations allegedly poison seven Critically Endangered elephants in Sumatra
(02/28/2014) Wildlife officials suspect foul play in the deaths of seven Sumatran elephants on the outskirts of Tesso Nilo National Park. Officials stumbled on the corpses of one female elephant, five young males, and one male calf in mid-February. Although the males had their tusks hacked off, the officials suspect the elephant were poisoned in revenge for disturbing illegal palm oil plantations inside the park.
Will tigers march ahead? Scientists find surprising connections between isolated populations in Central India
(02/25/2014) In May 2011, a young male Bengal tiger (Panthera tigris tigris) made its way to a village in the state of Karnataka in India. The tiger had been quite a hiker. To reach the village, it had walked more than 280 kilometers (174 miles) from Bandipur Tiger Reserve, a protected area famous for these elusive big cats.
Borneo monkeys lose a tenth of their habitat in a decade
(02/25/2014) Four species of langurs monkeys that are endemic to Borneo lost more than a tenth of their habitat in just ten years, finds a study published in the journal Biodiversity and Conservation.
Why are the tropics so rich with life?
(02/24/2014) Descending the latitudinal ladder to the tropics, you would likely notice a few things: increasingly equivalent stretches of day and night, warmer weather and beachgoers with more intense sunburns. You may also notice an abundance of plant and animal life. Generations of scientists since the days of Darwin and Wallace have observed that species richness increases as one moves toward the equator. This holds true for nearly every animal group, including micro-organisms, marine invertebrates, insects, amphibians, birds and mammals. But why is this?
The lemur end-game: scientists propose ambitious plan to save the world's most imperiled mammal family
(02/20/2014) Due to the wonderful idiosyncrasies of evolution, there is one country on Earth that houses 20 percent of the world's primates. More astounding still, every single one of these primates—an entire distinct family in fact—are found no-where else. The country is, of course, Madagascar and the primates in question are, of course, lemurs. But the far-flung island of Madagascar, once a safe haven for wild evolutionary experiments, has become an ecological nightmare. Overpopulation, deep poverty, political instability, slash-and-burn agriculture, illegal logging for lucrative woods, and a booming bushmeat trade has placed 94 percent of the world's lemurs under threat of extinction, making this the most imperiled mammal group on the planet. But, in order to stem a rapid march toward extinction, conservationists today publicized an emergency three year plan to safeguard 30 important lemur forests in the journal Science.
Shoot to conserve: Corey Knowlton's rhino hunt escalates the debate over trophy hunting and environmentalism
(02/20/2014) 'After a long conversation with the FBI I have decided to temporarily suspend my activity on this page. I want to thank all of you who have commented [on] this important issue of Black Rhino Conservation.' – Corey Knowlton, Feb 3, 2014. This was the last post on Corey Knowlton's Facebook page. Knowlton is the hunter who won the Dallas Safari Club auction on January 11th to kill a Critically Endangered black rhino. All the money—$350,000—will go to a fund to protect rhinos. The plan is that sometime soon—once the paperwork clears the U.S. Fish and Wildlife Service—Knowlton will go to Namibia on a "trophy hunt" (accompanied by a park service official), shoot the designated rhino, and bring the old bull's hide back home to Texas.
Animals of the Serengeti – book review
(02/19/2014) Animals of the Serengeti: And Ngorongoro Conservation Area by Adam Scott Kennedy and Vicki Kennedy is an easy-to-use guidebook that is also very readable. The region covered by the book is the Greater Serengeti area bounded in the west by Lake Victoria and the east by Lake Manyara in Tanzania, and in the north by southern Kenya.
Local communities key to saving the Critically Endangered Mexican black howler monkey
(02/14/2014) For conservation initiatives around the world, community involvement is often crucial. An additional challenge is how to conserve species once their habitats have become fragmented. A primatologist in Mexico is bringing these together in a celebration of a Critically Endangered primate species: the Mexican black howler monkey. In 2013 Juan Carlos Serio-Silva was part of a team that not only helped to secure the establishment of a protected area for the Mexican black howler monkey, but also engaged local communities in a week of festivities, dubbed the First International Black Howler Monkey Week.
Scientists discover new whale species
(02/14/2014) Beaked whales are incredibly elusive and rare, little-known to scientists and the public alike—although some species are three times the size of an elephant. Extreme divers, beaked whales have been recorded plunging as deep as 1,800 meters (5,900 feet) for over an hour. Few of the over 20 species are well-known by researchers, but now scientists have discovered a new beaked whale to add to the already large, and cryptic, group: the pointed beaked whale (Mesoplodon hotaula).
Featured video: camera traps catch jaguars, anteaters, and a sloth eating clay in the Amazon rainforest
(02/13/2014) These are sights that have rarely been seen by human eyes: a stealthy jaguar, a bustling giant armadillo, and, most amazingly, a sloth slurping up clay from the ground. A new compilation of camera trap videos from Yasuni National Park in the Ecuadorean Amazon shows a staggering array of species, many cryptic and rare.
Ivory trade's shocking toll: 65% of world's forest elephants killed in 12 years (warning: graphic image)
(02/12/2014) Forest elephants have suffered unprecedented butchery for their ivory tusks over the past decade, according to new numbers released by conservationists today in London. Sixty-five percent of the world's forest elephants have been slaughtered by poachers over the last dozen years, with poachers killing an astounding nine percent of the population annually. Lesser-known than their savannah cousins, a genetics study in 2010 found that forest elephants are in fact a distinct species, as far removed from savannah elephants as Asian elephants are from mammoths. These findings make the forest elephant crisis even more urgent.
Obama announces new strategy to tackle wildlife trafficking, including toughening ivory ban
(02/12/2014) Yesterday, the Obama administration announced an ambitious new strategy to help tackle the global illegal wildlife trade, including a near-complete ban on commercial ivory. The new strategy will not only push over a dozen federal agencies to make fighting wildlife trafficking a new priority, but will also focus on reducing demand for wildlife parts and actively engaging the international community. The U.S. is the world's second largest destination for illegal wildlife trafficking after China.
Proposed rail and road projects could devastate Nepal's tigers and rhinos
(02/06/2014) Chitwan National Park is a conservation success story. Since its establishment in 1973 the park's populations of both Bengal tigers (Panthera tigris tigris) and one-horned rhinos (Rhinoceros unicornis) have quintupled, a success achieved during a time when both species have been under siege globally by poachers. A UNESCO World Heritage site, the park is also a vital economic resource for locals: last year the park admitted over 150,000 tourists who brought in nearly $2 million in entry fees alone. But all this is imperiled by government plans for a new railway that would cut the park in half and a slew of new roads, according to a group of international conservationists known as the Alliance of Leading Environmental Researchers and Thinkers (ALERT).
Predator appreciation: how saving lions, tigers, and polar bears could rescue ourselves
(01/29/2014) In the new book, In Predatory Light: Lions and Tigers and Polar Bears, authors Elizabeth Marshall Thomas, Sy Montgomery, and John Houston, and photographers Cyril Christo and Marie Wilkinson share with us an impassioned and detailed appeal to appreciate three of the world's biggest predators: lions, tigers, and polar bears. Through lengthy discussions, combining themes from scientific conservation to local community folklore, In Predatory Light takes us step by step deeper into the wild world of these awe-inspiring carnivores and their varied plight as they facedown extinction.
Over 2,500 wolves killed in U.S.'s lower 48 since 2011
(01/28/2014) Hunters and trappers have killed 2,567 gray wolves in the U.S.'s lower 48 states since 2011, according to recent data. Gray wolves (Canis lupus) were protected by the Endangered Species Act (ESA) for nearly 40 years before being stripped of their protection status by a legislative rider in 2011. Last year total wolf populations were estimated at over 6,000 in the region.
Feral crèches: parenting in wild India
(01/28/2014) The Wildlife Conservation Society-India has been camera trapping wild animals for over 20 years in the Western Ghats. The results reveal the most intimate, fascinating and sometimes comical insights into animal behavior and ecology. These mammals generally become secretive and protective during parenting, and therefore we seldom get to see little ones in the wild. But discretely placed camera traps have not only caught glimpses of these adorable wild babies, but also produced wonderful family albums!
New dolphin discovered in the Amazon surprises scientists
(01/23/2014) Researchers have discovered a new species of river dolphin from the Amazon. Writing in the journal Plos One, scientists led by Tomas Hrbek of Brazil's Federal University of Amazonas formally describe Inia araguaiaensis, a freshwater dolphin that inhabits the Araguaia River Basin. It is the first true river dolphin discovered since 1918.
Snow leopards and other mammals caught on camera trap in Uzbekistan (photos)
(01/16/2014) Scientists knew that snow leopards (Panthera uncia) still survived in the Central Asian country of Uzbekistan, but late last year they captured the first ever photos. Camera traps in the Gissar Nature Reserve took photos of the big cats, along with bear, lynx, ibex, wild boar, and other mammals. The camera trap program was led by biologists Bakhtiyor Aromov and Yelizaveta Protas working with Panthera, WWF's Central Asia Program, and Uzbekistan's Biocontrol Agency.
For agoutis, the night is fraught with peril
(01/15/2014) In a study recently published in the online Animal Behavior journal, scientists from the US and the Netherlands have examined the impact of predation patterns on prey's food foraging habits. The two-year long study on Barro Colorado Island, Panama, focused on the predator-prey relationship between the Central American agouti (Dasyprocta punctata), a common rainforest rodent, and the ocelot (Leopardus pardalis).
German government gives tigers $27 million
(01/14/2014) At a summit in 2010, the world's 13 tiger range states pledged to double the number of tigers (Panthera tigris) in the wild by 2020. Today, non-tiger state Germany announced its assistance toward that end. Through its KfW Development Bank, the German government has pledged around $27 million (20 million Euro) to a new program run by the International Union for Conservation of Nature.
Trophy hunters auction off life of Critically Endangered black rhino
(01/13/2014) The Dallas Safari Club has auctioned off a permit to shoot-and-kill a Critically Endangered black rhino in Namibia for $350,000. The club says the proceeds from the auction will aid rhino conservation, but the move has upset many wildlife organizations and attracted protestors outside the closed-door auction. In fact the issue has become so contentious that the FBI is currently investigating purported death threats against the Dallas Safari Club members over the issue. Currently, less than 5,000 black rhinos survive in the wild today, a drop of 90 percent since 1960 as the species has been decimated by poaching and habitat loss.
Over 75 percent of large predators declining
(01/09/2014) The world's top carnivores are in big trouble: this is the take-away message from a new review paper published today in Science. Looking at 31 large-bodied carnivore species (i.e those over 15 kilograms or 33 pounds), the researchers found that 77 percent are in decline and more than half have seen their historical ranges decline by over 50 percent. In fact, the major study comes just days after new research found that the genetically-unique West African lion is down to just 250 breeding adults.
Lions face extinction in West Africa: less than 250 survive
(01/08/2014) The lions of West Africa, which may represent a distinct subspecies, are on the precipice of extinction. A sober new study in PLOS ONE reports that less than 250 mature lions survive in the region. Scientists have long known that West Africa's lions were in trouble, but no one expected the situation to be as dire as it was. In fact, in 2012 scientists estimated the population at over 500. But looking at 21 parks, scientists were shocked to find lions persisted in just four with only one population containing more than 50 individuals.
Requiem or recovery?: the Sumatran rhino 200 years after its description
(01/08/2014) In 1893, William Bell, a surgeon in the service of the Dutch East India Company stationed in Bencoolen, Sumatra, examined the body of a dead rhinoceros. The animal, a male, was relatively small as rhinoceroses go, measuring only four feet four inches at the shoulder and eight feet five inches from its nose to the tip of its tail. Dr. Bell noted that the animal resembled a large hog and judged it to be a young individual based upon the condition of the bones and teeth.
Rewilding Chile's savanna with guanacos could increase biodiversity and livestock
(01/06/2014) Local extinctions have occurred across a variety of habitats on every continent, affecting a gamut of species from large predators such as the wolves of North America, to tiny amphibians like the Kihansi spray toad of Tanzania. The long trek toward reversing such extinctions has begun, but it is not without its challenges, both ethical and logistical.
Curious bears take 'selfies' with camera traps
(12/26/2013) "Selfies" are all the rage this year, and even bears have jumped on the trend. Especially the shaggy-coated, termite-loving sloth bears (Melursus ursinus), who seem particularly fascinated by the cameras that scientists have put up in forests to secretly capture their stealthy moves.
Jaguars in Argentine Chaco on verge of local extinction
(12/23/2013) The majestic jaguar (Panthera onca), the largest of the New World cats, is found as far north as the southern states of the US, and as far south as northern Argentina. In the past jaguars ranged 1,500 kilometers (930 miles) further south, but their range has shrunk as habitat loss and human disturbance have increased. Overall, jaguars are classified as Near Threatened by the IUCN, but the level of risk facing jaguars varies by region. Populations in Argentina, at the present-day southern range limit, have previously been identified as some of the most threatened of them all.
Biggest new animal discoveries of 2013 (photos)
(12/23/2013) Thousands of species were scientifically described for the first time in 2013. Many of these were 'cryptic species' that were identified after genetic analysis distinguished them from closely-related species, while others were totally novel. Below are some of the most interesting "new species" discoveries that took place or were formally announced in 2013.
Unraveling the secrets of one of the world's most mysterious big cats
(12/22/2013) The Sunda clouded leopard has always been shrouded in mystery. Only declared a separate species from its mainland cousin, the Borneo clouded leopard, in 2006, the IUCN lists the cat as Endangered. The distinction between the Borneo clouded leopard (Neofelis nebulas) and the Sunda clouded leopard (Neofelis diardi) was made by ground-breaking molecular coding technologies and anatomy studies of the two species. Although it is Borneo's largest predator, very little is known about the Sunda leopard. As a medium-sized, well-camouflaged and mostly nocturnal animal, the leopard has evaded researchers since its discovery eight years ago.
New marsupial discovered in Ecuador
(12/20/2013) Researchers working in Ecuador have identified a previously unknown species of shrew-opossum, according to a study recently published in the Journal of Mammalogy. Contrary to its mousey appearance, Caenolestes sangay, named after the national park where it was discovered, is actually a marsupial. The team from Pacific Lutheran University set up more than 100 live traps over 15 nights on the eastern slopes of Andes. In the course of their research they recovered five specimens of the new species, each measuring approximately 10 centimeters (3.9 inches) long.
Featured video: what would a world without wildlife look like?
(12/20/2013) Greenpeace today released a clever video highlighting the global biodiversity crisis with a little help from a much-beloved Disney film. While it might seem unlikely the Africa's animals will vanish, this is exactly what's happening in parts of the continent due to poaching, unsustainable bushmeat trade, habitat loss, massive development projects that are often poorly planned, and a booming human population.
Little elephant is the first scientific record of dwarfism in the wild
(12/19/2013) Biologists in Sri Lanka have published the first documented evidence of dwarfism in an adult wild animal. A male Asian elephant (Elephas maximus) measuring just over 1.5 meters (five feet) in height was seen in an aggressive encounter with another male of average size. The elephant's small stature was due to disproportionately short legs, according to the findings published in the IUCN/SSC Asian Elephant Specialist Group journal Gajah. "The 'dwarf' was by far the main aggressor in the altercation and appeared to be older than the other, a young adult," states the study. "Other than for the disproportionately short legs, morphologically and behaviorally the dwarf appeared normal."
Top 10 HAPPY environmental stories of 2013
(12/19/2013) China begins to tackle pollution, carbon emissions: As China's environmental crisis worsens, the government has begun to unveil a series of new initiatives to curb record pollution and cut greenhouse emissions. The world's largest consumer of coal, China's growth in emissions is finally slowing and some experts believe the nation's emissions could peak within the decade. If China's emissions begin to fall, so too could the world's.
Madagascar's most famous lemur facing big threats
(12/18/2013) The ring-tailed lemur (Lemur catta), perhaps the most well-known of Madagascar’s endemic animals, is facing a "very high" risk of extinction in the wild. The Madagascar Section of the IUCN Primate Specialist Group reassessed the Red List status of ring-tailed lemurs and upgraded the species from Near-Threatened (2008) to Endangered (2012). Ring-tailed lemurs are facing extinction in some parts of Madagascar because of continued habitat loss, and more recently, species exploitation.
New Guinea animals losing vital tree cavities to logging, hunting practices
(12/17/2013) Across New Guinea, deforestation is occurring at increasing levels. Whether it be industrial logging, monoculture plantations, hunters felling trees in pursuit of arboreal wildlife, or other forms of forest conversion, deforestation is depleting not only forest carbon stocks and understory environments, but habitats for species who call tree cavities "home." A new study in mongabay.com's open-access journal, Tropical Conservation Science, evaluated whether a variety of man-made nest boxes could function as suitable substitutes for tree cavities.
Scientists make one of the biggest animal discoveries of the century - a new tapir
(12/16/2013) In what will likely be considered one of the biggest (literally) zoological discoveries of the Twenty-First Century, scientists today announced they have discovered a new species of tapir in Brazil and Colombia. The new mammal, hidden from science but known to local indigenous tribes, is actually one of the biggest animals on the continent, although it's still the smallest living tapir. Described in the Journal of Mammology, the scientists have named the new tapir Tapirus kabomani after the name for 'tapir' in the local Paumari language: Arabo kabomani.
Asian elephants depend on shifting cultivation during the dry season
(12/16/2013) Asian elephants (Elephas maximus) have co-existed with human practices for thousands of years, including shifting cultivation. Shifting agriculture encompasses a variety of different practices that involve abandoning plots for periods of time to allow natural vegetation to grow. The practice consists of cutting and burning the natural vegetation at the end of the dry season and cultivating with the rains. Harvesting is completed by the end of the wet season.
Camera traps find less mammals than expected in Costa Rican corridor
(12/16/2013) A new study using camera traps in mongabay.com's open-access journal Tropical Conservation Science has surveyed the diversity of medium and large-sized predators in the San Juan-La Selva biological corridor in Costa Rica, whilst also demonstrating how alteration of habitat is affecting the use of this corridor.
Odd porcupine hugely imperiled by hunting, deforestation
(12/16/2013) The thin-spined porcupine, also known as the bristle-spined rat, is a truly distinct animal: a sort of cross between New World porcupines and spiny rats with genetic research showing it is slightly closer to the former rather than the latter. But the thin-spined porcupine (Chaetomys subspinosus), found only in Brazil's Atlantic Forest, is imperiled by human activities. In fact, a new study in mongabay.com's open access journal Tropical Conservation Science found that the species remains a target for hunters, despite a reputation for tasting terrible.
Sonar directly impacts whale behavior, according to military study
(12/13/2013) Noises from pile-driving, explosives, ship motors and other industrial activities have all been linked to adverse effects on marine wildlife. A new study, funded by the US Navy and published in Proceedings of the Royal Society B, suggests that military sonar may be directly impacting whale behavior. The idea that sonar might affect the behavior of whales is not new. A number of reports in the past have linked the use of military sonar to mass stranding events of beaked whales and baleen whale species.
Big data shows tropical mammals on the decline
(12/12/2013) The world's largest remote camera trap initiative—monitoring 275 species in 17 protected areas—is getting some big data assistance from Hewlett-Packard (HP). To date, the monitoring program known as the Tropical Ecology Assessment and Monitoring (TEAM) Network has taken over 1.5 million photos of animals in 14 tropical countries, but conservationists have struggled with how to quickly evaluate the flood of data.
New mountain porcupine discovered in Brazil (photos)
(12/09/2013) In Brazil's Baturite Mountains, scientists have uncovered a new species of prehensile-tailed porcupine, according to a new paper in Revista Nordestina de Biologia. Dubbed, the Baturite porcupine (Coendou baturitensis), the new species was discovered when scientists noticed significant differences between it and its closest relative, the Brazilian porcupine (Coendou prehensilis). The name prehensile-tailed refers to these porcupines long, mobile tail which they use as a fifth limb to adroitly climb trees.
Like ancient humans, some lemurs slumber in caves
(12/05/2013) After playing, feeding, and socializing in trees all day, some ring-tailed lemurs (Lemur catta) take their nightly respite in caves, according to a new study in Madagascar Conservation and Development. The findings are important because this is the first time scientists have ever recorded primates regularly using caves (see video below).
Microsoft founder funds Africa-wide elephant survey to measure ivory poachers' toll
(12/04/2013) Beginning next year, light planes and helicopters will undertake the first ever continent-wide aerial survey of Africa's vanishing elephant populations. The hugely ambitious initiative, which will count elephant herds in 13 countries, is being funded by Microsoft founder, Paul Allen, through his Paul G. Allen Family Foundation.
86 percent of big animals in the Sahara Desert are extinct or endangered
(12/03/2013) Bigger than all of Brazil, among the harshest ecosystems on Earth, and largely undeveloped, one would expect that the Sahara desert would be a haven for desert wildlife. One would anticipate that big African animals—which are facing poaching and habitat loss in other parts of the world—would thrive in this vast wilderness. But a new landmark study in Diversity and Distributions finds that the megafauna of the Sahara desert are on the verge of total collapse.
Where have all the dugongs gone?
(12/03/2013) Legend has it that lonely sailors mistook them for beautiful, mythical mermaids. But as it turns out, the muse behind these beguiling sea nymphs was instead the dugong – a rather ungainly, gentle and mini-bus sized marine mammal, cousin to the manatees and part of the sea cow family. However, while they may have once fuelled stories for fairytales and Disney movies, their far-from-glamorous life is currently under serious threat in many parts of the world.
22,000 elephants slaughtered for their ivory in 2012
(12/02/2013) As the African Elephant Summit open in Botswana today, conservationists released a new estimate of the number of African elephants lost to the guns of poachers last year: 22,000. Some 15,000 elephants killed in 42 sites across 27 countries on the continent, according to newly released data from the CITES program, Monitoring the Illegal Killing of Elephants (MIKE). But conservationists estimate another 7,000 went unreported. The number killed is a slight decrease over 2011 numbers of 25,000.
