(07/22/2010) Visitors to the Orangutan Care Center and Quarantine (OCCQ) are always delighted by the sight of playful young orangutans. Hairy orange youngsters swinging through the branches or tossing balls around always induce fits of cooing and camera clicking. These activities appear to be so natural that it is easy to forget these are orphans in rehabilitation school and one of the main classes is Enrichment. The term enrichment has become a catchword in the world of captive animal husbandry in the past few years and for many organizations, enrichment has become a new focus as more and more research reveals how critical enrichment is to the physical, mental, and emotional wellbeing of captive animals.
Amazing reefs: how corals 'hear', an interview with Steve Simpson
(07/21/2010) Corals aggregate to form vast reefs, which are home to numerous species and provide vital ecological services such as protecting shorelines. However, coral reefs are one of the most threatened ecosystems in the world due to many factors, such as global warming and ocean acidification. Recent research by Simpson and his team of scientists has shown that corals, rather than drifting aimlessly after being released by their parent colonies and by chance landing back on reefs, instead find their way purposefully to reefs by detecting the sound of snapping shrimps and grunting fish on the reef. However, that discovery also means that the larvae might struggle to find reefs when human noises, like drilling or boats, mask the natural ocean sounds.
Conservation photography: on shooting and saving the world's largest temperate rainforest, an interview with Amy Gulick
(07/11/2010) Most of the US's large ecosystems are but shadows of their former selves. The old-growth deciduous forests that once covered nearly all of the east and mid-west continental US are gone, reduced to a few fragmented patches that are still being lost. The tall grassy plains that once stretched further than any eye could see have been almost wholly replaced by agriculture and increasing suburbs. Habitats, from deserts to western forests, are largely carved by roads and under heavy impact from resource exploitation to invasive species. Coastal marine systems, once super abundant, have partially collapsed in many places due to overfishing, as well as pollution and development. Despite this, there are still places in the US where the 'wild' in wilderness remains largely true, and one of those is the Tongass temperate rainforest of Southeast Alaska.
With 'psychological cunning' wild cat lures monkeys by mimicking their babies' calls
(07/08/2010) It sounds like something out of a fairy-tale: the big bad predator lures its gullible prey by mimicking a loved one: 'why grandma, what big teeth you have!' But in this case it's the shocking strategy of one little-known jungle feline. In 2005 researchers with the Wildlife Conservation Society (WCS) were watching a group of eight pied tamarins ( Saguinus bicolor), squirrel-sized monkeys, feeding on a ficus tree in the Reserva Florestal Adolpho Ducke in Brazil. They then heard the sound of tamarin babies, but were surprised to see that the sound was not coming from young tamarins, but a hungry margay (Leopardus wiedii), a small cat native to Central and South America, which was hidden from the tamarins.
Forgotten species: the cryptic Jerdon's courser
(07/06/2010) According to my Oxford English Dictionary, 'cryptic' means: 'secret, mystical; mysterious; obscure in meaning; enigmatic'. This is the perfect adjective for the rare Indian bird, Jerdon's courser (Rhinoptilus bitorquatus). 'It is not so easy to spot as it is a small bird and when you show the torch it crouches and merges with the surroundings. So we need very good trained eyes to look for them,' Dr. P. Jeganathan recently told mongabay.com.
Uncovering the intelligence of insects, an interview with Lars Chittka
(06/29/2010) Many people would likely consider 'insect intelligence' a contradiction in terms, viewing insects—when they think of them as anything more than pests—as something like hardwired tiny robots, not adaptive, not intelligent, and certainly not conscious. However, research over the last few decades have shown that a number of well-studied insects are capable of performing amazing intellectual feats, from recognizing individuals to employing a symbolic language in a behavior known as a 'bee waggle'. "Already in 1900, Buttel-Reepen asked whether honeybees are mere reflex machines—and emphatically denied that claim," Dr. Lars Chittka, professor of Sensory and Behavioral Ecology at Queen Mary University in London, told mongabay.com in an interview. "Over the last century, we have seen a fundamental change in perspective on the learning capacities of insects, and there a now several credible lines of evidence that insects are capable of cognitive feats that had previously been ascribed only to 'higher' vertebrates".
Planting figs could save endangered species in Borneo
(06/28/2010) In one of the most remote and undisturbed forests of Borneo, the Maliau Basin in the Malaysian state of Sabah, researchers picked a single fig tree (Ficus caulocarpa) and surveyed the species feeding from it over a 5-day-period. Their findings, published in Tropical Conservation Science, shows that a fig tree over a short period of time feeds a high percentage of endangered species, prompting researchers to recommend replanting figs in disturbed forests as a way to save Borneo's frugivores (fruit-eating species) from extinction.
Saving one of West Africa's last hippo populations
(06/28/2010) A new study in Tropical Conservation Science highlights the need for further conservation actions to save one of West Africa's last hippo populations, located in southern Burkina Faso. Researchers surveyed 41 hippos in the 'Mare aux Hippopotames' Biosphere Reserve of Burkina Faso in 2008, up by six individuals since 2006, but down from a population of 68 in 1985. The hippos (Hippopotamus amphibious) remain threatened by possible conflict with locals and the fact that a number of their ponds are outside the protected area.
How do Asian elephants survive in fragmented and unprotected landscapes?
(06/28/2010) A new study in Tropical Conservation Science has found that Asian elephants living in a combination of fragmented forests and agricultural landscapes still depend on natural landscapes—rivers and forests—for survival. Following two herds of Asian elephants (Elephas maximus) in the Valparai plateau among the Anamalai Hills of India for three years, researchers found that the elephants spent much of their time, relative to their availability, near rivers and amid forest fragments. When they entered agricultural landscapes they preferred Eucalyptus and coffee to tea.
The penguin crisis: over 60 percent of the world's penguins threatened with extinction
(06/10/2010) Everyone loves penguins. With their characteristic black-and-white 'tuxedo' markings, upright waddle, and childlike stature, penguins seem at once exotic and familiar: exotic because they live far from most human habitations, familiar because they appear in innumerable books and movies. From Mr. Popper's Penguins to Happy Feet, and from March of the Penguins to And Tango Makes Three, penguins pop-up everywhere. The flightless birds have even provided the name and symbol to one of the world's most successful publishing houses. Yet despite their popularity amid the human kingdom, few people seem aware that penguins worldwide are facing an extinction crisis.
Already on the edge, lemurs could become victims of climate change
(06/08/2010) Expanding beyond well-known victims such as polar bears and coral reefs, the list is growing of species likely to be hard hit by climate change: from lizards to birds to amphibians. Now a new study has uncovered another group of species vulnerable to a warmer world: lemurs.
Saltwater crocodiles surf across the ocean
(06/06/2010) Despite being poor swimmers, researchers have discovered that the saltwater crocodile (also known as estuarine) commonly travels long distances over open oceans by riding ocean currents. The discovery, published inJournal of Animal Ecology, solves an unknown mystery of why saltwater crocodiles (Crocodylus porosus) are found across vast distance in the Pacific, yet have not diverged into different species.
'No hope now remains' for the Alaotra grebe
(05/31/2010) World governments have missed their goal of stemming biodiversity loss by this year, instead biodiversity loss has worsened according to scientists and policy-makers, and a little rusty-colored bird, the Alaotra grebe (Tachybaptus rufolavatus) is perhaps a victim of this failure to prioritize biodiversity conservation. Native to a small region in Madagascar, the grebe has been declared extinct by BirdLife International and the IUCN Red List due to several factors including the introduction of invasive carnivorous fish and the use of nylon gill-nets by local fishermen, which now cover much of the bird's habitat, and are thought to have drowned diving grebes. The bird was also poached for food.
World's 'number one frog' faces extinction from New Zealand government
(05/26/2010) Archey's frog is a survivor: virtually unchanged evolutionarily for 150 million years, the species has survived the comet that decimated the dinosaurs, the Ice Age, and the splitting of continents. Seventy million years ago New Zealand broke away from Australia, essentially isolating Archey's frog and its relatives from all predatory mammals. Yet, if the New Zealand government has its way this species may not survive the century, let alone the next few decades. The New Zealand government has put forward a controversial proposal to begin opening three of the nation's protected areas to mining: Great Barrier Island, Paparoa National Park, and Coromandel Peninsula where the last populations of Archey's frogs live. According to critics, the government's proposal could push Archey's frog toward extinction, while negatively impacting a number of other endangered species, beloved wild lands, and a nation driven by tourism.
Photos: the penis-like mushroom and other top 10 new species of 2009
(05/23/2010) The International Institute for Species Exploration at Arizona State University has released its annual top 10 list of new species discovered last year. This time the list includes a two inch penis-like mushroom, a minnow named after Bram Stoker's world-famous horror-character, a bomb-throwing deep sea worm, a giant carnivorous plant named after TV personality and conservationist David Attenborough, and a beautifully patterned frogfish.
BP and the Perilous Voyage of Bama the Manatee
(05/23/2010) To the degree that Americans are paying attention to the environmental plight of marine wildlife in the Gulf of Mexico, they may focus most upon dolphins and whales. However, the U.S. public is much less familiar with another marine mammal, the manatee, which could also be placed in jeopardy as a result of the BP oil spill. One of the most outlandish creatures on the planet, the shy and retiring manatee, which gets its name from an American Indian word meaning "Lady of the Water", is one of my favorite animals.
One man's mission to save Cambodia's elephants
(05/17/2010) Since winning the prestigious 2010 Goldman Environmental Prize in Asia, Tuy Sereivathana has visited the US and Britain, even shaking hands with US President Barack Obama, yet in his home country of Cambodia he remains simply 'Uncle Elephant'. A lifelong advocate for elephants in the Southeast Asian country, Sereivathana's work has allowed villagers and elephants to live side-by-side. Working with Fauna and Flora International (FFI) he has successfully brought elephant-killing in Cambodia to an end. As if this were not enough, Sereivathana has helped curb the destruction of forests in his native country and built four schools for children who didn't previously have formal education opportunities.
Climate change devastating lizards worldwide: 20 percent estimated to face extinction
(05/13/2010) Lizards have evolved a variety of methods to escape predators: some will drop their tail if caught, many have coloring and patterning that blends in with their environment, a few have the ability to change their colors as their background changes, while a lot of them depend on bursts of speed to skitter away, but how does a lizard escape climate change? According to a new study in Science they don't. The study finds that lizards are suffering local extinctions worldwide due exclusively to warmer temperatures. The researchers conclude that climate change could push 20 percent of the world's lizards to extinction within 70 years.
A nation of tragedies: the unseen elephant wars of Chad
(05/12/2010) Stephanie Vergniault, head of SOS Elephants in Chad, says she has seen more beheaded corpses of elephants in her life than living animals. In the central African nation, against the backdrop of a vast human tragedy—poverty, hunger, violence, and hundreds of thousands of refugees—elephants are quietly vanishing at an astounding rate. One-by-one they fall to well-organized, well-funded, and heavily-armed poaching militias. Soon Stephanie Vergniault believes there may be no elephants left. A lawyer, screenwriter, and conservationist, Vergniault is a true Renaissance-woman. She first came to Chad to work with the government on electoral assistance, but in 2009 after seeing the dire situation of the nation's elephants she created SOS Elephants, an organization determined to save these animals from local extinction.
How hornbills keep Asian rainforests healthy and diverse, an interview with Shumpei Kitamura
(04/26/2010) Hornbills are one of Asia's most attractive birds. Large, colorful, and easier to spot than most other birds, hornbills have become iconic animals in the tropical forests of Asia. Yet, most people probably don't realize just how important hornbills are to the tropical forests they inhabit: as fruit-eaters, hornbills play a key role in dispersing the seeds of tropical trees, thereby keeping forests healthy and diverse. Yet, according to tropical ecologist and hornbill-expert Shumpei Kitamura, these beautiful forest engineers are threatened by everything from forest loss to hunting to the pet trade.
Jane Goodall renews her faith in nature and humanity during the "Gombe 50" anniversary, An interview with Dr. Jane Goodall
(04/12/2010) 2010 marks a monumental milestone for the Jane Goodall Institute (JGI) and its founder, Dr. Jane Goodall, DBE. Fifty years ago, Goodall, who is today a world-renowned global conservation leader, first set foot on the shores of Lake Tanganyika, in what is now Tanzania’s Gombe National Park. The chimpanzee behavioral research she pioneered at Gombe has produced a wealth of scientific discovery, and her vision has expanded into a global mission 'to empower people to make a difference for all living things.' Time, however, has not stood still for Gombe. The wild chimps of the area have suffered as the local human population has swelled. Gombe National Park is now a forest fragment, a 35-square-kilometer island of habitat isolated in a sea of subsistence farming. Because the problems facing Gombe—unsustainable land practices, overpopulation, and a cycle of poverty—are typical of many other areas, lessons learned by Dr. Goodall and her team provide valuable insights for solutions at Gombe and beyond.
Hope for survival as isolated orangutans joined by rope bridge
(04/11/2010) Researchers in the Malaysian state of Sabah in Borneo are joyful after receiving confirmation that a young male orangutan used a rope bridge to cross a river, which has separated one orangutan population from another. Due to logging and clearing forests for oil palm plantations, which cover 18 percent of land in Sabah, orangutans on the Kinabantangan River have been cut into fragmented populations.
Forgotten species: the subterranean Gekko gigante
(04/08/2010) Travelers to tropical destinations are likely familiar with the gecko. Clinging to walls and ceilings of buildings—sometimes staring down at you from the bedroom ceiling or glancing at you quizzically from the bathroom door—the small adhesive-footed lizard could be aptly described in some tropical areas as ubiquitous. Despite the apparent commonness of some species, geckos are delightful lizards with round wide eyes, a thick gripping tongue, and of course that amazing knack of seemingly defying gravity with specialized toe pads. But not all geckos are as easily found—or as common—as those hanging out, literally, in a jungle lodge. The Gekko gigante, also known as the Gigante narrow-disked gecko, has been little- noticed by the public. Even scientists know little about the lovely gray-and-blue gecko beyond the fact that it lays its eggs on cool moist cave walls in two Philippine Islands.
Sumatran rhino loses pregnancy: conservationists saddened but remain resolute
(03/31/2010) Rhino conservationists' hopes were dampened today by news that Ratu, a female Sumatran rhino, had lost her pregnancy. Just months after the announcement of the pregnancy—the first at Indonesia’s Sumatran Rhino Sanctuary in Way Kambas National Park—Ratu lost the embryo. Still, say conservationists, the very fact that Ratu became pregnant at all should keep hope alive for the beleaguered species.
When it comes to Yellow Fever, conserving howler monkeys saves lives
(03/29/2010) Abundant and diverse wildlife help people in many ways: for example bees pollinate plants, birds and mammals disperse seeds, bats control pest populations, and both plants and animals have produced life-saving medicines and technological advances. But how could howler monkeys save people from a Yellow Fever outbreak? A new study in the open-access journal Tropical Conservation Science explores the link between howler monkeys, mosquitoes, and humans during a recent yellow fever outbreak in the state of Rio Grande do Sul, Brazil.
Diverse habitats needed for survival of small mammals in Mexico
(03/29/2010) A new study in Tropical Conservation Science shows that small tropical mammals in Mexico—bats and rodents—require a variety of habitats to thrive. Surveying mammal populations in the Isthmus of Tehuantepec, Oaxaca, Mexico, researchers found that sites comprising the greatest habitat diversity carried also the greatest diversity of rodents. In turn bats lived in all variety of habitats and moved easily from one to another.
Scientists discover world's first amphibious insects: Hawaiian caterpillars
(03/22/2010) Scientists have never before discovered a truly amphibious insect until now: writing in the Proceedings of the National Academy of Sciences researchers have announced the discovery of 12 species of Hyposmocoma moths in the Hawaiian islands which they consider truly amphibious—that is a species able to survive both on land and underwater indefinitely.
Forgotten Species: the marooned pygmy three-toed sloth
(03/16/2010) Many people consider tropical islands mini-paradises: sanctuaries cut-off from the rest of the world. Some species flourish on islands for the same reason. With few predators and a largely consistent environment, once a species has comfortably adapted to its habitat there's little to do but thrive. That is until something changes: like humans showing up. Changes in confined island ecosystems often have large and rapid impacts, too fast and too big for marooned species to survive.
Video: no sunlight, no food, frozen conditions, but NASA finds complex life
(03/16/2010) In a discovery at the bottom of the world that could have implications on the search for extraterrestrial life, researchers were astounded to find an amphipod swimming beneath a massive Antarctic ice sheet.
Falklands Dispute: Argentine Sovereignty Won’t Solve the Problem
(03/15/2010) With Britain now moving to explore for oil and gas in the Falkland Islands, Argentina has cried foul. Buenos Aires claims that the Falklands, or the Malvinas as Argentines refer to the islands, represent a "colonial enclave" in the south Atlantic. The islands have been a British possession since 1833, and the local inhabitants consider themselves thoroughly British. Yet, Argentina claims the Malvinas as the country inherited them from the Spanish crown in the early 1800s. In 1982 Argentina seized the islands but was later expelled by a British naval force. The war was short but bloody, costing 650 Argentine and 250 British lives.
US Congressman pushes for bird-friendly buildings
(03/11/2010) Birds may see pleasanter skies in the US soon, if Congressman Mike Quigley has his way. Quigley, a democrat from Illinois, has introduced legislation that would require all federal buildings to become bird-friendly, potentially saving the lives of millions of birds every year.
Secrets of the Amazon: giant anacondas and floating forests, an interview with Paul Rosolie
(03/10/2010) At twenty-two Paul Rosolie has seen more adventure than many of us will in our lifetime. First visiting the Amazon at eighteen, Rosolie has explored strange jungle ecosystems, caught anaconda and black caiman bare-handed, joined indigenous hunting expeditions, led volunteer expeditions, and hand-raised a baby giant anteater. "Rainforests were my childhood obsession," Rosolie told Mongabay.com. "For as long as I can remember, going to the Amazon had been my dream […] In those first ten minutes [of visiting], cowering under the bellowing calls of howler monkeys, I saw trails of leaf cutter ants under impossibly large, vine-tangled trees; a flock of scarlet macaws crossed the sky like a brilliant flying rainbow. I saw a place where nature was in its full; it is the most amazing place on earth."
Orangutans use calls for a variety of reasons
(03/10/2010) Mature male orangutans produce what scientists call 'long calls', which can be heard for one kilometer in all directions even in dense forests. New research in Ethology has uncovered that these calls are employed for a number of reasons and provide information about who is calling and why.
Why seed dispersers matter, an interview with Pierre-Michel Forget, chair of the FSD International Symposium
(03/07/2010) There are few areas of research in tropical biology more exciting and more important than seed dispersal. Seed dispersal—the process by which seeds are spread from parent trees to new sprouting ground—underpins the ecology of forests worldwide. In temperate forests, seeds are often spread by wind and water, though sometimes by animals such as squirrels and birds. But in the tropics the emphasis is far heavier on the latter, as Dr. Pierre-Michel Forget explains to mongabay.com. "[In rainforests] a majority of plants, trees, lianas, epiphytes, and herbs, are dispersed by fruit-eating animals. […] As seed size varies from tiny seeds less than one millimetres to several centimetres in length or diameter, then, a variety of animals is required to disperse such a continuum and variety of seed size, the smaller being transported by ants and dung beetles, the larger swallowed by cassowary, tapir and elephant, for instance."
Octopus pretends to be flounder to avoid predators
(03/04/2010) Marine researchers have discovered the Atlantic longarm octopus mimicking not only the color and appearance of the peacock flounder, but also its unique style of swimming in order to convince predators it's something it's not.
Prehistoric snake gobbled-up dinosaur babies
(03/02/2010) A fossilized snake has been discovered inside a titanosaur nest in India, leading researchers to conclude that the snake fed on newly-hatched dinosaur babies, rather than their eggs like modern snakes. Paleontologist and snake expert Jason Head says that the snake, known as Sanajeh indicus, lacked the wipe-jaws needed to swallow eggs, but just-hatched baby titanosaurs would have been perfect prey for the 3.5 meter (nearly 12 feet) long serpent. Titanosaurs belong to the sauropods, long-necked herbivorous dinosaurs which includes the world's largest animals to ever walk the land.
Common pesticide changes male frogs into females, likely devastating populations
(03/01/2010) One of the world's most popular pesticides, atrazine, chemically castrates male frogs and in some instances changes them into completely functionally females, according to a new study in the Proceedings of the National Academy of Sciences. The authors conclude that atrazine likely plays a large, but unsuspected role in the current global amphibian crisis.
Galapagos fur seals exploit warmer waters to establish colony off Peru
(02/25/2010) As suggested by their name, the Galapagos fur seals were once endemic to the Galapagos island chain off the coast of Ecuador. But in a warming world species are on the move, and the Galapagos fur seal is no exception. According to a recent story in Reuters the Galapagos fur seals have established what appears to be a permanent colony off the coast of Peru, 900 miles from their home.
Grizzly bears move into polar bear territory, threatening polar cubs
(02/24/2010) Two of the world's largest land carnivores are converging on the same territory, according to data recently published in Canadian Field Naturalist. Grizzly bears ( Ursus arctos horribilis) are moving into an area that has long been considered prime polar bear habitat in Manitoba, Canada. Although polar bears (Ursus maritimus) are bigger than their grizzly relatives—they are the world's largest land carnivores—biologists are concerned that grizzlies will kill polar cubs, further threatening the polar bear, which is already thought to be imperiled by ice loss in the Arctic.
Cricket mothers warn offspring about spiders before they hatch
(02/21/2010) Cricket mothers are long gone by the time their infants hatch, so one would assume that cricket parents have little effect on their offspring's behavior. Not so, according to a new study in the American Naturalist which proves that mother crickets have the potential to teach their offspring—while still in their eggs—about the hazards of spiders.
Pregnancy gives new hope for rhino on-the-brink of extinction
(02/18/2010) Though they grew up world's apart, Sumatran rhinos Ratu and Andalas have given conservationists new-found hope for saving the embattled species. The rhino couple is expecting, according to the Sumatran Rhino Sanctuary at Way Kambas, Indonesia. One of the world's most endangered big mammals, Sumatran rhinos are unique due to their hairy bodies and small size (at least compared to other rhinos). The last surviving members of the genus Dicerorhinus, only 200 Sumatran rhinos are estimated to survive in the wild. Ratu's pregnancy holds special significance for a number of reasons. It is the first pregnancy at the Sumatran Rhino Sanctuary; it will be both Ratu's and Andalas' first calf; it is also the first pregnancy in captivity since Andalas' mother Emi—the only Sumatran rhino to successfully give birth in captivity for 112 years—passed away last fall.
Expedition to photograph world's rarest cetacean threatened by lack of funding
(02/11/2010) Little known beyond the waters of the Gulf of California, the world's smallest cetacean (a group including whales, dolphins, and porpoises) is hanging on by a thread. The vaquita—which in Spanish means 'little cow'—has recently gained the dubious distinction of not only being the world's smallest cetacean, but the also the world's rarest. In 2006 it was announced that the Yangtze river dolphin, or baiji, was likely extinct, and conservationists fear the Critically Endangered 'little cow' is next. An expedition for this year is set to identify vaquita individuals, but even this is threatened by lack of funding.
Forgotten Species: the fiery Luristan Newt
(02/08/2010) The salamander was a mythical creature before it was a real one: the word salamander means a legendary lizard that both survived-in and could extinguish fire. A creature that the Ancient Greeks, including Aristotle, appeared to readily believe in. No one knows how the term salamander transferred from a mythical fire-dwelling monster to the small amphibious animals it applies to today, but I have a theory. Perhaps the sight of salamanders like Luristan newt—charcoal-black and flame-orange—caused people in the seventeenth century to lend the name of myth to the taxa.
Sophisticated flying methods allow insects to hitchhike on fast winds
(02/04/2010) Researchers have long been fascinated by how insects migrate thousands of kilometers, for example from Britain to the Mediterranean. A new study, published in Science shows that although tiny, insects are not at the mercy of winds as expected. Instead they employ sophisticated flight behaviors to use fast winds to their advantage.
Why top predators matter: an in-depth look at new research
(02/02/2010) Few species have faced such vitriolic hatred from humans as the world's top predators. Considered by many as pests—often as dangerous—they have been gunned down, poisoned, speared, 'finned', and decimated across their habitats. Even where large areas of habitat are protected, the one thing that is often missing are top predators. However, new research over the past few decades is showing just how vital these predators are to ecosystems. Biologists have long known that predators control populations of prey animals, but new studies show that they may do much more. From controlling smaller predators to protecting river banks from erosion to providing nutrient hotspots, it appears that top predators are indispensible to a working ecosystem. Top predators sit at the apex of an ecosystem's food chain. Wolves in Alaska, tigers in Siberia, lions in Kenya, white sharks in the Pacific are all examples of top predators.
Photos: New tropical frog undergoes remarkable transformation
(02/01/2010) Nature never runs out of surprises. Exploring Sudest Island off of Papua New Guinea, researchers discovered a new species of frog that drastically changes its appearance from juvenile to adulthood, a transformation that has never been seen in another frog.The new species, named Oreophryne ezra, is shiny black with bright yellow spots. Yet when it matures, the frog becomes rose-colored and even its eyes change from black to blue.
Indonesia plans to sell endangered tigers as pets to the wealthy
(01/21/2010) Indonesia has a new plan to save the Critically Endangered Sumatran tiger, reports the AFP: sell captive-born tigers as pets. The proposed price is 100,000 US dollars for a pair of Sumatran tigers with the money going to conservation efforts, though it was unclear who would manage these funds.
Natural rafts carried Madagascar's unique wildlife to its shores
(01/20/2010) Imagine, forty million years ago a great tropical storm rises up on the eastern coast of Africa. Hundreds of trees are blown over and swept out to sea, but one harbors something special: inside a dry hollow rests a small lemur-like primate. Currents carry this tree and its passenger hundreds of miles until one gray morning it slides onto a faraway, unknown beach. The small mammal crawls out of its hollow and waddles, hungry and thirsty, onto the beach. Within hours, amid nearby tropical forests, it has found the sustenance it needs to survive: in a place that would one day be named Madagascar.
The Caribbean's wonderfully weird (and threatened) mammals, an interview with Jose Nunez-Mino
(01/18/2010) Not many people know the solenodon and the hutia, yet for the fortunate few that have encountered them, these strange little-studied mammals—just barely holding on in the Caribbean island of Hispaniola—deserve to be stars of the animal kingdom. "I could not quite believe it the first time I held a solenodon; I was in utter awe of this mesmerizing mammal. […] They have a long flexible snout which is all down to the fact that it is joined to the skull by a unique ball-and-socket joint. This makes it look as if the snout is almost independent to the rest of the animal. You can’t help but feel fascinated by the snout and inevitably it does make you smile," Dr. Jose Nunez-Mino, the Project Manager for a new initiative to study and conserve the island's last mammals, told mongabay.com in an interview.
Forgotten species: discovering the shimmer of Maathai's Longleg
(01/13/2010) Few species receive less respect and less conservation attention than insects. This despite the fact that they are some of the most diverse species on the planet andthey provide a number of essential services to humankind, including pollination, pest control, production (for example honey and silk), waster recycling, and indications of habitat health. Scientists are not only unsure just how many species of insects are threatened in world; they are equally uncertain how many insects exist. Currently there are nearly a million insect species described by science, but millions more likely exist. It's probable that innumerable insect species have vanished before even being catalogued by entomologists.
