(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.
Wonderful Creatures: the bizarre-looking marine worm with an incredibly important ecological role
(02/13/2014) Almost everyone knows what an earthworm is, but these very familiar animals are just one variation on a very rich theme that is at its most fabulously varied in the oceans. The mind-boggling appearances and lifestyles of the marine segmented worms are perfectly exemplified by this week's animal.
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.
Incredible encounter: whales devour European eels in the darkness of the ocean depths
(02/11/2014) The Critically Endangered European eel makes one of the most astounding migrations in the wild kingdom. After spending most of its life in Europe's freshwater rivers, the eel embarks on an undersea odyssey, traveling 6,000 kilometers (3,720 miles) to the Sargasso Sea where it will spawn and die. The long-journeying eels larva than make their way back to Europe over nearly a year. Yet by tracking adult European eels (Anguilla anguilla) with electronic data loggers, scientists have discovered that some eels never make it to their spawning ground, but instead are swallowed-up in the depths by leviathans.
Photos: mass turtle hatching produces over 200,000 babies
(02/11/2014) Biologists recently documented one of nature's least-known, big events. On the banks of the Purus River in the Brazilian Amazon, researchers witnessed the mass-hatching of an estimated 210,000 giant South American river turtles (Podocnemis expansa). The giant South American river turtle, or Arrau, is the world's largest side-necked turtle and can grow up to 80 centimeters long (nearly three feet).
Cambodia protects forest for giant ibis
(02/10/2014) Cambodia has set aside an area of forest just slightly smaller than Singapore to protect the country's national bird: the giant ibis (Thaumatibis gigantea). Listed as Critically Endangered by the IUCN Red List, the giant ibis is down to just a few hundred birds.
On edge of extinction, could drones and technology save the Little Dodo?
(02/10/2014) Almost nothing is known about the little dodo, a large, archaic, pigeon-like bird found only on the islands of Samoa. Worse still, this truly bizarre bird is on the verge of extinction, following the fate of its much more famous relative, the dodo bird. Recently, conservationists estimated that fewer than 200 survived on the island and maybe far fewer; frustratingly, sightings of the bird have been almost non-existent in recent years. But conservation efforts were buoyed this December when researchers stumbled on a juvenile little dodo hanging out in a tree. Not only was this an important sighting of a nearly-extinct species, but even more so it proved the species is still successfully breeding. In other words: there is still time to save the species from extinction so long as conservationists are able to raise the funds needed.
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).
Alpine bumblebees capable of flying over Mt. Everest
(02/05/2014) The genus Bombus consists of over 250 species of large, nectar-loving bumblebees. Their bright coloration serves as a warning to predators that they are unwelcome prey and their bodies are covered in a fine coat of hair - known as pile - which gives them their characteristically fuzzy look. Bumblebees display a remarkably capable flight performance despite being encumbered with oversized bodies supported by relatively diminutive wings.
How hunters have become key to saving Bulgaria's capercaillie
(02/04/2014) Surprising clatter cuts through the silence in the snowy forest shortly before sunrise. The powerful clicking sounds like a dropping Ping-Pong ball before culminating in a loud pop resembling the opening of a champagne bottle. This sound is heard clearly and far. Propped on a thick pine tree branch, with a peacock-fanned tale, relaxed wings and head pointing skyward, a western capercaillie is singing. The song terminates with a low-frequency sound similar to scraping a fork to the bottom of a frying pan. It's exactly during those last few moments of singing that something unusual happens: the male bird goes temporarily deaf. Hence the species' common name in Bulgarian—deaf bird.
Wonderful Creatures: meet the animal that has evolved a cushy, worry-free life inside an octopus
(01/30/2014) The range of habitats that animals have come to occupy is nothing short of staggering. Take the dicyemids for example. They are among the simplest animals on the planet, with a tiny, worm-like adult body that consists of between 10 and 40 cells. They have no organs, body cavities or even guts—a structural simplicity which is a consequence of where and how they live. The only place you will find adult dicyemids is inside the bodies of cephalopods, typically octopuses and cuttlefish where large numbers of them cling to the inner wall of the mollusc's kidney.
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.
A series of oil spills sully Caribbean paradise, coating mangroves and wildlife (photos)
(01/29/2014) On December 17th, officials first discovered a massive oil spill in the Caribbean-island nation of Trinidad and Tobago. Since then, a series of oil spills have been discovered, coating beaches, sullying mangrove forests, and very likely decimating wildlife in Trinidad's Gulf of Paria. The oil spills have been linked to the state-owned oil company, Petrotrin, which has claimed that sabotage is behind at least two of the spills. However Trinidad and Tobago's Environmental Management Authority has recently slapped the company with a $3.1 million fine by for the damage, while some politicians have called for an independent investigation into the slew of spills.
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!
287 amphibian and reptile species in Peruvian park sets world record (photos)
(01/28/2014) It's official: Manu National Park in Peru has the highest diversity of reptiles and amphibians in the world. Surveys of the park, which extends from high Andean cloud forests down into the tropical rainforest of the Western Amazon, and its buffer zone turned up 155 amphibian and 132 reptile species, 16 more than the 271 species documented in Ecuador's Yasuní National Park in 2010.
Amazing discovery in Antarctica: sea anemones found living upside down under ice (photos)
(01/27/2014) Sea anemones are supposed to sit on the bottom of the ocean, using their basal disc (or adhesive foot) to rest on a coral reef orsand. So, imagine the surprise of geologists in Antarctica when they discovered a mass of sea anemones hanging upside from the underside of the Ross Ice Shelf like a village of wispy ghosts. The researchers weren't even there to discover new life, but to learn about south pole currents through the Antarctic Geological Drilling (ANDRILL) Program via a remotely-operated undersea robot.
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.
One quarter of sharks and rays threatened with extinction
(01/22/2014) One quarter of all shark and ray species are threatened with extinction, according to a new study published in the open-access journal eLife. The paper analyzed the threat and conservation status of 1,041 species of chondrichthyans—the class of fish whose skeletons are made of cartilage instead of bone which includes sharks, rays, skates and chimaeras—and found this group to be among the most threatened animals in the world.
One lizard, four species: the collared treerunner
(01/21/2014) Now, that’s a horse of a different color. Or, in this case, a lizard of another species--four species. Recent research suggests that the collared treerunner (Plica plica), previously thought of as one widespread species, is actually four distinct species inhabiting diverse geographical areas east of the Andes in northern South America.
Photos: Japanese fishermen slaughter 41 dolphins, capture 52 in 'The Cove'
(01/21/2014) The annual dolphin hunt in Taiji, Japan ended on Monday with dozens being slaughtered for meat and captured for sale to amusement parks, reports Sea Shepherd, an ocean activist group that campaigns against the practice and just released photos documenting the weekend's harvest.
Red toad discovered in the upper reaches of the Amazon
(01/19/2014) Scientists have described a previously unknown species of toad in the Peruvian Andes.
Over 1,000 rhinos killed by poachers in South Africa last year
(01/17/2014) In another sign that Africa's poaching crisis has gotten completely out of control, South Africa lost 1,004 rhinos to poachers last year. According to the numbers released today by the South African Department of Environmental Affairs, 2013 was the worst year yet for rhino poaching in the country with nearly 3 rhinos killed every day.
Court orders logging company to clean up pollution disaster in Chile wetlands
(01/17/2014) Chile is probably best known for its volcanoes, earthquakes and the formidable peaks of the Andes, but as a country that spans 4,300 km (2,670 miles) from top to bottom, it also boasts a huge variety of bird life. And, until recently, it was home to what was thought to be the largest population of black-necked swans (Cygnus melancoryphus) in South America. Not long ago, these swans, as well as 100 other species of rare or vulnerable bird species, could be seen nesting in the Carlos Anwandter Nature Sanctuary in Valdivia, a Ramsar site that covers 12,000 acres in the south of Chile. But in 2004 the swans began to die.
Wonderful Creatures: A nematode drama played out in a millipede's gut
(01/17/2014) Nematodes are typically small animals that to the naked eye look very much alike; however, these creatures are fantastically diverse —on a par with the arthropods in terms of species diversity. At face value, nematodes lack the charisma of larger animals, so there are very few biologists who have made it their life’s work to understand them. Those who do have been rewarded with a glimpse of the incredible diversity of these animals, an example of which is the complex menagerie of nematodes that dwell in the guts of large, tropical millipedes.
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.
High-living frogs hurt by remote oil roads in the Amazon
(01/14/2014) Often touted as low-impact, remote oil roads in the Amazon are, in fact, having a large impact on frogs living in flowers in the upper canopy, according to a new paper published in PLOS ONE. In Ecuador's Yasuni National Park, massive bromeliads grow on tall tropical trees high in the canopy and may contain up to four liters of standing water. Lounging inside this micro-pools, researchers find a wide diversity of life, including various species of frogs. However, despite these frogs living as high as 50 meters above the forest floor, a new study finds that proximity to oil roads actually decreases the populations of high-living frogs.
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.
PHOTOS: Glowing fish - study finds widespread biofluorescence among fish
(01/10/2014) Biofluorescence is widespread among marine fish species, indicating its importance in communication and avoiding detection, finds a new study published in the journal PLOS ONE. The research shows that biofluorescence — a phenomenon where organisms absorb light, transform it, and emit it as a different color — is more common in the animal kingdom than previously known.
Wonderful Creatures: the lightning-fast Stenus beetles
(01/10/2014) Rove beetles are among the most diverse animals on the planet, with around 56,000 species currently described. Amongst this multitude of species is a dazzling array of adaptations perhaps best illustrated by the genus Stenus. These beetles, with their bulbous eyes and slender bodies are often found near water running swiftly over the wet ground and clambering among the vegetation.
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.
Scientists uncover new crocodile in Africa
(01/07/2014) Scientists working in Africa have uncovered a new crocodile species hiding in plain site, according to a paper published in the Proceedings of the Royal Society B. Looking at the molecular data of the slender-snouted crocodile, the researchers discovered two distinct species: one in West Africa and another in Central Africa. Although mostly lumped together as one species (Mecistops cataphractus) for over a hundred and fifty years, the scientists found that the two species have actually been split for at least seven million years, well before the evolution of hominins.
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.
Good news: Refuge for last blue-throated macaws doubles in size in Bolivia
(01/02/2014) A reserve that is home to the world's largest population of the critically endangered blue-throated macaw (Ara glaucogularis) has been more than doubled in size, reports the American Bird Conservancy (ABC), a group that helped fund the expansion.
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.
Conservation Hail Mary works: Mate for near-extinct fish found!
(12/20/2013) Researchers are celebrating after an urgent global search turned up a female mate for a fish that is on the brink of extinction.
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.
