Economic slowdown leads to the pulping of Latvia's forests

(01/23/2012) The economic crisis has pushed many nations to scramble for revenue and jobs in tight times, and the small Eastern European nation of Latvia is no different. Facing tough circumstances, the country turned to its most important and abundant natural resource: forests. The Latvian government accepted a new plan for the nation's forests, which has resulted in logging at rates many scientists say are clearly unsustainable. In addition, researchers contend that the on-the-ground practices of state-owned timber giant, Latvijas Valsts meži (LVM), are hurting wildlife and destroying rare ecosystems.


Seals, birds, and alpine plants suffer under climate change

(01/11/2012) The number of species identified by scientists as vulnerable to climate change continues to rise along with the Earth's temperature. Recent studies have found that a warmer world is leading to premature deaths of harp seal pups (Pagophilus groenlandicus) in the Arctic, a decline of some duck species in Canada, shrinking alpine meadows in Europe, and indirect pressure on mountain songbirds and plants in the U.S. Scientists have long known that climate change will upend ecosystems worldwide, creating climate winners and losers, and likely leading to waves of extinction. While the impacts of climate change on polar bears and coral reefs have been well-documented, every year scientists add new species to the list of those already threatened by anthropogenic climate change.


Animal picture of the day: dueling green iguanas

(01/03/2012) Found throughout Central and South America and parts of the Caribbean, the green iguana (Iguana iguana) is a large, mostly herbivorous lizard.


New species of frog sings like a bird

(12/12/2011) If you're trudging through the high-altitude rainforests of northern Vietnam and you hear bird song, you might want to check the trees for frogs. Yes, that's right: frogs. A new species of tree frog has been discovered in Vietnam that researchers say has a uniquely complex call that makes it sound more like a bird than a typical frog. Discovered in Pu Hoat Proposed Nature Reserve, the new species, dubbed Quang's tree frog (Gracixalus quangi), dwells in the forests at an altitude 600-1,300 meters (nearly 2,000-4,265 feet).


Small mammals use Borneo pitcher plant as toilet in exchange for nectar

(11/08/2011) Tree shrews and nocturnal rats in the forests of Borneo have a unique relationship with carnivorous pitcher plants. The mammals defecate, and the pitchers are happy to receive. A study published on May 31 in the Journal of Tropical Ecology shows a species of giant mountain pitcher plants (Nepenthes rajah) supplements its diet with nitrogen from the feces of tree shrews (Tupaia montana) that forage in daylight and summit rats (Rattus baluensis) active at night. When the small mammals lick nectar from the underside of the pitcher’s lid, they stand directly over the jug-shaped pitcher organ.


Rat uses 'poison arrow' toxin from tree to defend against predators

(08/02/2011) The African crested rat, a rodent from East Africa, applies to plant toxin from tree bark to make itself poisonous, reports a new study published in Proceedings of The Royal Society B..


Pictures: Researchers to track proboscis monkey in Borneo by satellite

(07/24/2011) Researchers with the Sabah Wildlife Department and Danau Girang Field Center in Malaysia have become the first to fit a proboscis monkey with a satellite tag.


Fish use tools

(07/17/2011) A blackspot tuskfish (Choerodon schoenleinii) has been photographed picking up a clam in its mouth, swimming over to a rock, and then using the rock as an anvil by smashing the clam against it until it breaks open. In the journal Coral Reefs scientists argue this is the first conclusive evidence of a fish using tools. Once thought only the domain of humans, biologists have found that tool use is actually present all over the animal kingdom, from elephants to chimps, and crows to capuchins. Such tool use is often considered evidence of higher intelligence.


Brainy lizards rival birds in intelligence

(07/13/2011) Reptiles have long been thought to be dim-witted, but a new study in Biology Letters finds that the Puerto Rican anole, a type of lizard, can match birds in smarts. Using cognitive tests that have been previously used on birds, researchers with Duke University found that the lizards were capable of solving a problem they've never encountered before, remembering the solution in future trials, and even changing techniques when presented with new challenges. In fact, the tiny anoles solved the test with fewer tries than birds. Given reptiles' reputation of being slow-on-the uptake the head author, Manuel Leal, said the findings are 'completely unexpected'.


World's 'most social' lizard builds multigenerational homes

(05/31/2011) Researchers from Macquarie University in Australia have discovered that the threatened great desert burrowing skink lizard forms stable families that construct and maintain elaborate underground homes, reports ABC News. This is the first lizard in the world known to practice such familial behavior. Native to central Australia, researchers are conducting studies on the great desert skink (Liopholis kintorei) at Uluru Kata-Tjuta National Park, where rangers monitor the threatened species. Over 5,000 species of lizard have been documented globally, but only the Uluru skinks live together in immediate and social families that invest in the construction of long-lasting homes.


Uncovering the private lives of Amazon wildlife through camera traps

(05/20/2011) One of the best words to describe Amazon wildlife, including large mammals and birds, is cryptic. A person can spend a day trekking through the dense green and brown foliage of the Amazon and see nothing more than a few insects, maybe a frog here and there if they have good eyes. In fact, researchers have spent years in the jungle and never seen a jaguar, let alone a tapir. Some species like the bushdog and the giant armadillo are even more cryptic. Almost never encountered by people, in some parts of the Amazon they have taken on a mythic status, more rumor around the fire than reality. However, camera traps—automated cameras that take a flash photo whenever an animal triggers an infrared sensor—in the Amazon have begun to reveal long-sought information about the presence and abundance of species, providing new data on range and territories. And even at times giving glimpses into the private lives of species that remain largely shrouded in mystery.


Forgotten species: the endearing Tenkile tree kangaroo

(05/03/2011) With their long snout, furry body, soft eyes, and, at times, upright stance, tree kangaroos often remind me of the muppets. Of course, if there were any fairness in the world, the muppets would remind me of tree kangaroos, since kangaroos, or macropods, have inhabited the Earth for at least 5 million years longer than Jim Henson’s muppets. But as a child of the 1980s, I knew about muppets well before tree kangaroos, which play second fiddle in the public imagination to their bigger, boxing cousins. This is perhaps surprising, as tree kangaroos possess three characteristics that should make them immensely popular: they are mammals, they are monkey-like (and who doesn't like monkeys?), and they are desperately 'cute'.


With 24 eyes, box jellyfish are constantly looking up

(04/28/2011) Lacking brains does not mean box jellyfish are incapable of complex visual behavior, according to a new study in Current Biology. Researchers have known for over a century that box jellyfish support an astounding two-dozen eyes. Now, they are beginning to find out how these eyes are used: four of a box jellyfish's 24 eyes are always peering up out of the water finds the new study. These four eyes, no matter how the body is oriented, allow the jellyfish to navigate their shallow, obstacle-filled habitats, such as mangroves—and keep them from straying too far from home.


Elephants: the gardeners of Asia's and Africa's forests

(04/25/2011) It seems difficult to imagine elephants delicately tending a garden, but these pachyderms may well be the world's weightiest horticulturalist. Elephants both in Asia and Africa eat abundant amounts of fruit when available; seeds pass through their guts, and after expelled—sometimes tens of miles down the trail—sprouts a new plant if conditions are right. This process is known by ecologists as 'seed dispersal', and scientists have long studied the 'gardening' capacities of monkeys, birds, bats, and rodents. Recently, however, researchers have begun to document the seed dispersal capacity of the world's largest land animal, the elephant, proving that this species may be among the world's most important tropical gardeners.


Giant fish help grow the Amazon rainforest

(04/12/2011) A fruit in the flooded Amazon falls from a tree and plops in the water. Before it can even sink to the floor, a 60-pound monster fish with a voracious appetite gobbles it. Nearly a week later—and miles away—the fish expels its waste, including seeds from the fruit eaten long ago and far away. One fortunate seed floats to a particularly suitable spot and germinates. Many years later the new fruit tree is thriving, while the same monster-fish returns from time-to-time, waiting for another meal to drop from the sky. This process is known as seed-dispersal, and while researchers have studied the seed-dispersal capacity of such species as birds, bats, monkeys, and rodents, one type of animal is often overlooked: fish.


The value of the little guy, an interview with Tyler Prize-winning entomologist May Berenbaum

(04/06/2011) May Berenbaum knows a thing or two about insects: in recognition of her lifelong work on the interactions between insects and plants, she has had a character on The X-Files named after her, received the Public Understanding of Science and Technology Award for her work in making science accessible to the public, and this year has been awarded the prestigious Tyler Environmental Prize. "Winning the Tyler Prize is an incredible honor—most of my scientific heroes have been Tyler Prize winners and I’m exceedingly grateful to be considered worthy of being included among their ranks," Berenbaum told mongabay.com in an interview. "The Prize is also tremendously enabling—because the money is unrestricted I can use it to carry out projects that have been difficult to fund."


Pet trade, palm oil, and poaching: the challenges of saving the 'forgotten bear'

(03/20/2011) Siew Te Wong is one of the few scientists who study sun bears (Ursus malayanus). He spoke with Laurel Neme on her "The WildLife" radio show and podcast about the interesting biological characteristics of this rare Southeast Asian bear, threats to the species and what is being done to help them. Sun bears are the smallest of the eight bear species. They’re about half the size of a North American black bear and typically sport a tan crescent on their chests. Similar to the "moon bear," or Asian black bear, the sun bear’s name comes from this marking, which looks like a rising or setting sun.


Fearful Symmetry—Man Made, an interview with John Vaillant, author of The Tiger

(03/14/2011) In The Tiger, John Vailliant weaves a haunting and compelling true narrative of men who live—or die—with tigers. No doubt the story itself is on-the-edge of your seat reading. As well, the book provides factual information on the 400 or so Amur Tigers remaining, and the raw milieu that is Primorye, Far East Russia—a wilderness and people unto their own. What is special, transcendent even in this story, however, murmurs uncomfortably in the background. Questions emerge from deep taiga snow, not unlike the unseen Panchelaza Tiger. What exactly is our relationship with apex predators? How do people live with them? How would you live with them in your backyard? What if your pet dog disappeared? As we ourselves are apex predators, are we wise enough, tolerant enough, compassionate enough to share this planet with them? Evidence today points to the contrary, but this can change.


Critically endangered capuchins make tools to gather termites

(03/10/2011) Less than 200 blond capuchins (Cebus falvius) survive in the highly-fragmented habitat of Brazil's Atlantic Forest. But this tiny group of monkeys, only rediscovered in 2006, is surprising scientists with its adept tool-using abilities. Displaying similar behavior to that which made the chimpanzees of Gombe famous worldwide, the blond capuchins modify sticks to gather termites from trees; however, according to the study published in Biology Letters the blond capuchins use two techniques never witnessed before: twisting the stick when inside the termite nest and tapping the nest before inserting the stick.


Photos: two new freshwater stingrays discovered in the Amazon

(03/09/2011) Few people probably realize that in the rivers and lakes of the Amazon rainforest large stingrays glide, searching for crustaceans and small fish. Equipped with a powerful barbed tail they are often feared by locals. However, even as big as these fish are, new species continue to be described. Recently, scientists have identified two new species of Amazonian freshwater stingray near Iquitos, Peru. The new stingrays are unique enough to be placed in a new genus (the taxonomic level above species) called Heliotrygon, the first new Amazonian stingray genus to be described in nearly 25 years.


Birds experience 'empathy' for their hatchlings

(03/09/2011) A new study has uncovered what many chicken owners would say is evident: a mother hen experiences empathy for her hatchlings. Published in the Proceedings of the Royal Society B, the study found that mother hens show both physiological responses and changes in behaviors when their chicks are even mildly distressed.


Elephants cooperate as well as chimps

(03/07/2011) A new study proves that elephants understand how sometimes two is better than one. Working with Asian elephants (Elephas maximus) at the Thai Elephant Conservation Center, researchers reconstructed a classic cooperation test that was originally developed for chimpanzees. Subjects must pull on a rope to receive a reward, such as food, however—and here's the crux—the treat is only released if two subjects cooperate by pulling on two different ropes simultaneously. The paper published in Proceedings of the National Academy of Sciences found that elephants were as capable of cooperation as chimpanzees.


New species of zombie-creating fungi discovered

(03/02/2011) As everyone knows, human zombies are created when an uninfected human is bitten by a member of the brain-craving undead. But what about ant zombies? Yes, that's right: ant zombies.


Saving Madagascar's largest carnivorous mammal: the fossa

(02/17/2011) Madagascar is a land of wonders: dancing lemurs, thumbnail-sized chameleons, the long-fingered aye-aye, great baobab trees, and the mighty fossa. Wait—what? What's a fossa? It's true that when people think of Madagascar rarely do they think of its top predator, the fossa—even if they are one of the few who actually recognizes the animal. While the fossa gained a little notice in the first Madagascar film by DreamWorks, its role in the film was overshadowed by the lemurs. In this case, art imitates life: in conservation and research this feline-like predator has long lived in the shadow of its prey, the lemur. Even scientists are not certain what to do with the fossa: studies have shown that it's not quite a cat and not quite a mongoose and so the species—and its few Malagasy relatives—have been placed in their own family, the Eupleridae, of which the fossa (Cryptoprocta ferox) is the biggest. But if this is the first you've heard of such matter, don't feel bad: one of the world's only fossa-researchers, Mia-Lana Lührs also stumbled on the species.


A lion's story, an interview with the filmmakers of The Last Lions

(02/14/2011) The new theatrical film, The Last Lions does not open, as one would expect, with a shot of lions or even an African panorama. Instead the first shot is a view of our planet from space at night. Billions of artificial lights illuminate continent showing just how much humans over the past few thousand years have come to dominate our world. Then comes the lions, but not in person, just in this staggering, and little known, statistic: in the last 50 years we have gone from a population of 450,000 lions to 20,000 today, a 95% decline. While the dramatic story of the The Last Lions follows the perils and tragedies of lion motherhood in one of the world's last untouched places—the Okavango Delta—this statistic hangs over the film, reminding us that the story we are witnessing is on the verge of extinction.


Tiny bats trade in caves for pitcher plants in Borneo

(01/26/2011) A tiny species of bat in Borneo has chosen an unusual roost: a carnivorous pitcher plant, according to a recent study. The study examines how this behavior actually benefits both the bats and the plants, creating a symbiotic relationship.


King of dinosaurs was a hunter, not a scavenger

(01/26/2011) Ecologists say they have used a computer model to put to rest a nearly century-old debate. Did Tyrannosaurus Rex, one of the world's most well-known dinosaurs, hunt down its prey like a lion on the plains, or, instead, did it scavenge meals from other hunters like a vulture? According to scientists with the Zoological Society of London (ZSL) the Tyrannosaurus had only one choice in order to survive: hunt.


Using water bodies to track Asian elephants

(12/19/2010) One would think that it would be easy to track Asia's largest land animal, but in fact Asian elephants (Elephas maximus) are generally shy, mostly nocturnal, and stick to the forest whenever possible. Yet, it's vital for conservationists to track the herd, if they are to keep them safe from poaching and protect both elephants and locals from potential conflict. However, a new study in mongabay.com's open access journal Tropical Conservation Science has developed a unique strategy to track elephant herds in Sri Lanka by sticking to the water.


How cannibal crickets choose their victims

(12/17/2010) Social interactions influence cannibalistic behavior among migratory bands of crickets, finds a new study published in the Public Library of Science. Cannibalism in turn is a major driving force behind the nature and direction of cricket swarms.


Deforestation sparks giant rodent invasions

(12/15/2010) Capybara are expanding into areas of deforestation throughout South America, reports a new study conducted by Kansas State University researchers and published in the journal of Global Change Biology. The study is the first to report capybara populations invading historically arid regions and finds that the presence of invasive capybara can hinder habitat restoration.


Cheetahs reproduce more successfully after early pregnancies

(11/15/2010) Early pregnancies prepare a cheetah for a life of productive motherhood, new research shows. A study published on 20 September in Conservation Letters advises captive breeding programs to focus on breeding female cheetahs at young ages to set the stage for many litters throughout their lives. The world's fastest animal, the cheetah has not outpaced a disheartening march toward extinction. Populations have declined from an estimated 100,000 a century ago to about 13,000 today. For years, researchers have pointed to the high genetic similarities among individual cheetahs as the main reason why captive cheetahs don't often get pregnant.


Saving the best for last: a journey into the final phases of orangutan rehabilitation

(11/08/2010) Rehabilitation is a powerful word these days. Fashionable, too. In wildlife conservation, rehabilitation can serve functions ranging from augmenting threatened animal populations to desperate attempts to save species from permanent extinction. At its base, rehabilitation consists of handling, preparing and releasing wild animals that have been in some way negatively affected by humans. Rehabilitation programs cover the globe (from cottage-scale sparrow and raccoon rescues in suburban parks to well-established raptor protection programs, wolf rehabilitation and public education about these wild predators in Colorado, semi-touristy rehabilitation centers in Thailand housing everything from gibbons to elephants, vet hospitals dedicated to flu-ridden bobtail lizards in Australia, and sexy lion and cheetah hubs in southern Africa which breed endangered serval cats). The motivations behind these programs are also diverse, but the umbrella goal is unified: to aid the continued survival, so often precarious, of animals valued by people.


Biological shocker: snake reproduces asexually

(11/03/2010) Researchers have discovered a biological shocker: female boa constrictors are capable of giving birth asexually. But the surprise doesn't end there. The study in Biology Letters found that boa babies produced through this asexual reproduction—also known as parthenogenesis—sport a chromosomal oddity that researchers thought was impossible in reptiles.


Undercover for animals: on the frontline of wildlife crime in the US

(11/03/2010) Special Agent O’Connor is a veteran wildlife law enforcement officer, with over 20 years of service under belt. She began her career in wildlife law enforcement as a Conservation Police Officer for the Illinois Department of Natural Resources, where she served for eight years. She then moved to federal wildlife law enforcement with the US Fish and Wildlife Service, where she was first posted to Ann Arbor, Michigan, and then to St. Paul, Minnesota. During that time, she investigated several major cases that led to felony convictions for violations of wildlife laws. She now serves as a training officer at the Federal Law Enforcement Training Center (FLETC), the interagency law enforcement training organization that serves 88 Federal agencies, in Georgia.


After months on the run, man-eating tiger caught

(10/28/2010) A male Bengal tiger that killed eight people was captured after a months-long chase by officials with India's Forest Department and biologists with the local conservation organization, Wildlife Trust of India (WFI), in the Indian state of Uttar Pradesh. After avoiding laced bait and tranquilizer darts, the tiger was finally trapped by officials earlier this month. Even after being tranquilized three times, the animal still lashed out, injuring several villagers who had begun throwing rocks at it. Eventually, though, the hunt for the cat ended with its capture.


Picture: new monkey discovered in Myanmar

(10/26/2010) Hunters' reports have led scientists to discover a new species of monkey in the northern forests of Myanmar. Discovered by biologists from the Myanmar Biodiversity and Nature Conservation Association with support from primatologists with Fauna & Flora International (FFI) and the People Resources and Biodiversity Foundation, the strange looking primate is a member of the snub-nosed monkey family, adding a fifth member to this unmistakably odd-looking group of Asian primates. However, the species survives in only a small single population, threatened by Chinese logging and hunting.


Elephant tromping benefits frogs and lizards

(10/25/2010) While elephants may appear destructive when they pull down trees, tear up grasses or stir up soils, their impacts actually make space for the little guys: frogs and reptiles. The BBC reports that a new study in African Journal of Ecology finds that African bush elephants (Loxodonta Africana), facilitate herpetofauna (i.e. amphibians and reptiles) biodiversity when they act as ecosystem engineers.


Monarch butterflies medicate their sick kids

(10/12/2010) A new study in Ecology Letters has discovered that monarch butterflies employ medicinal plants to treat their larva. Researchers found that certain species of milkweed, which the larva feed on, can reduce the threat of a sometime deadly parasite. However, even more surprising: "we have also found that infected female butterflies prefer to lay their eggs on plants that will make their offspring less sick, suggesting that monarchs have evolved the ability to medicate their offspring," says lead author Jaap de Roode.


Fighting poachers, going undercover, saving wildlife: all in a day's work for Arief Rubianto

(09/29/2010) Arief Rubianto, the head of an anti-poaching squad on the Indonesian island of Sumatra best describes his daily life in this way: "like mission impossible". Don't believe me? Rubianto has fought with illegal loggers, exchanged gunfire with poachers, survived four days without food in the jungle, and even gone undercover—posing as a buyer of illegal wildlife products—to infiltrate a poaching operation. While many conservationists work from offices—sometimes thousands of miles away from the area they are striving to protect—Rubianto works on the ground (in the jungle, in flood rains, on rock faces, on unpredictable seas, and at all hours of the day), often risking his own life to save the incredibly unique and highly imperiled wildlife of Sumatra.


The effect of forest regeneration strategies on beetles

(09/27/2010) As conservationists attempt to find the best way to re-establish forests in abandoned areas, a new study in the open-access journal Tropical Conservation Science compares the impacts on bess beetles of different method to regeneration forest. Bess beetles are important dead wood-recyclers in the forest. Looking at three different forests in the Colombian Andes—natural regeneration, monoculture reforestation, and an old-growth forest as a baseline—researchers found that old-growth and natural regeneration had the highest diversity of bess beetles, while old-growth sported the greatest abundance of beetles.


Tigers successfully reintroduced in Indian park

(09/27/2010) Poachers killed off the last Bengal tiger in India's Sariska Tiger Reserve in 2004. Four years later, officials transferred three tigers from Ranthambhore National Park to Sariska in an attempt to repopulate the park with the world's biggest feline. A new study in mongabay.com's open-access journal Tropical Conservation Science evaluates the reintroduction by tracking radio-collared tigers and studying their scat.


Indian carnivore eats mostly fruit

(09/27/2010) When is a carnivore no longer a carnivore? A new study in mongabay.com's open access journal Tropical Conservation Science has found that the brown palm civet (Paradoxurus jerdoni), a cat-sized tree-loving carnivore, lives almost entirely off fruit and seeds. Studying over a 1000 feces from the brown palm civet during three years, researchers found that 97 percent of its diet was composed of plants, not meat. Given its penchant for fruit, researchers argue that the brown palm civet is an important disperser of tropical plants, playing a vital ecological role rarely connected to civets.


Into the Congo: saving bonobos means aiding left-behind communities, an interview with Gay Reinartz

(09/23/2010) Unlike every other of the world's great apes—the gorilla, chimpanzee, and orangutan—saving the bonobo means focusing conservation efforts on a single nation, the Democratic Republic of the Congo. While such a fact would seem to simplify conservation, according to the director of the Bonobo and Congo Biodiversity Initiative (BCBI), Gay Reinartz, it in fact complicates it: after decades of one of world's brutal civil wars, the DRC remains among the world's most left-behind nations. Widespread poverty, violence, politically instability, corruption, and lack of basic infrastructure have left the Congolese people in desperate straits.


Tigers discovered living on the roof of the world

(09/20/2010) A BBC film crew has photographed Bengal tigers, including a mating pair, living far higher than the great cats have been documented before. Camera traps captured images and videos of tigers living 4,000 meters (over 13,000 feet) in the tiny Himalayan nation of Bhutan.


How the overlooked peccary engineers the Amazon, an interview with Harald Beck

(09/20/2010) When people think of the Amazon rainforest, they likely think of roaring jaguars, jumping monkeys, marching ants, and squeezing anacondas. The humble peccary would hardly be among the first animals to cross their mind, if they even know such pig-like animals exists! Yet new research on the peccary is proving just how vital these species are to the world's greatest rainforest. As seed dispersers and seed destroyers, engineers of freshwater habitats and forest gaps, peccaries play an immense, long overlooked, role in the rainforest. "Peccaries have the highest density and biomass of any Neotropical mammal species. Obviously these fellows have quite an appetite for almost anything, but primarily they consume fruits and seeds. Their specialized jaws allow them to crush very hard seeds. The cracking sounds can be heard through the thick vegetation long before we could see them. As peccary herds bulldoze through the leaf litter in search for insects, frogs, seeds, and fruits, they destroy (i.e. snap and trample) many seedlings and saplings, sometimes leaving only the bare ground behind," Harald Beck, assistant professor at Towson University in Maryland, told mongabay.com in an interview.


Coral reef survival depends on the super small, an interview with Forest Rohwer

(08/30/2010) If you take a teaspoon and dip it into the ocean what will you have? Some drops of lifeless water? Only a few decades ago this is what scientists would have said, however, the development of increasingly powerful microscopes have shown us a world long unknown, which has vital importance for the survival of one of the world's most threatened and most treasured ecosystems: coral reefs. A single milliliter of water is now known to contain at least a million living microbes, i.e. organisms too small to see without a microscope. After discovering their super-abundant presence, researchers are now beginning to uncover how these incredibly tiny life-forms shape the fate of the world's coral reefs.


A slow comeback for the endangered Eurasian otter in France

(08/29/2010) In the late 1970s, the fate of the Eurasian Otter (Lutra lutra) in France was very gloomy. By just looking at the otter's range map, one could see that most of the country was left with vast regions devoid of a species that was once found in every region. Estimations barely reached 1,500 otters left in the wild for the whole country. Today, 2,000 to 3,000 individuals are believed to room in creeks and rivers mostly in the Massif Central, the Atlantic side (Bretagne) and western area, in particular in the wetland of Poitevin. The upward trend in population size is good news and a step towards reconstituting sustainable populations, however, the overall population is still critically low. By contrast, in the early 1900s otters were quite abundant in France with over 50,000 wild animals.


The biology and conservation of declining coral reefs, an interview with Kristian Teleki

(08/15/2010) Coral reefs are often considered the "rainforests of the sea" because of their amazing biodiversity. In fact, coral reefs are one of the most diverse ecosystems on earth. It is not unusual for a reef to have several hundred species of snails, sixty species of corals, and several hundred species of fish. While they comprise under 1% of the world’s ocean surface, one-quarter of all marine species call coral reefs their home. Fish, mollusks, sea stars, sea urchins, and more depend on this important ecosystem, and humans do too. Coral reefs supply important goods and services–from shoreline protection to tourism and fisheries–which by some estimates are worth $375 billion a year.


Stunning monkey discovered in the Colombian Amazon

(08/11/2010) While the Amazon is being whittled away on all sides by logging, agriculture, roads, cattle ranching, mining, oil and gas exploration, today's announcement of a new monkey species proves that the world's greatest tropical rainforest still has many surprises to reveal. Scientists with the National University of Colombia and support from Conservation International (CI) have announced the discovery of a new monkey in the journal Primate Conservation on the Colombian border with Peru and Ecuador. The new species is a titi monkey, dubbed the Caquetá titi ( Callicebus caquetensis). However, the announcement comes with deep concern as researchers say it is likely the new species is already Critically Endangered due to a small population living in an area undergoing rapid deforestation for agriculture.


Hunting threatens the other Amazon: where harpy eagles are common and jaguars easy to spot, an interview with Paul Rosolie

(08/05/2010) If you have been fortunate enough to visit the Amazon or any other great rainforest, you've probably been wowed by the multitude and diversity of life. However, you also likely quickly realized that the deep jungle is not quite what you may have imagined when you were a child: you don't watch as jaguars wrestle with giant anteaters or anacondas circle prey. Instead life in the Amazon is small: insects, birds, frogs. Even biologists will tell you that you can spend years in the Amazon and never see a single jaguar. Yet rainforest guide and modern day explorer Paul Rosolie says there is another Amazon, one so pristine and with such wild abundance that it seems impossible to imagine if not for Rosolie's stories, photos, and soon videos. This is an Amazon where the big animals—jaguars, tapir, anaconda, giant anteaters, and harpy eagles—are not only abundant but visible. Free from human impact and overhunting, these remote places—off the beaten path of tourists—are growing ever smaller and, according to Rosolie, are in danger of disappearing forever.

    Carbon dioxide (CO2) emissions generated from mongabay.com operations (server, data transfer, travel) are mitigated through an association with Anthrotect,
    an organization working with Afro-indigenous and Embera communities to protect forests in Colombia's Darien region.
    Anthrotect is protecting the habitat of mongabay's mascot: the scale-crested pygmy tyrant.
