(04/17/2012) The Wildlife Conservation Society (WCS) has pledged to work with all of its institutions to save at least half of the world's most 25 endangered turtles as listed in a report by WCS and the Turtle Conservation Coalition last year. The program will include both conservation work in the field as well as participation from WCS's zoological institutions for captive breeding and future reintroductions. Even with WCS's ambitious program, however, it is likely this century will see a number of turtle extinctions.
(03/26/2012) Anyone who doubts cryptozoology, which in Greek means the "study of hidden animals," should remember the many lessons of the past 110 years: the mountain gorilla (discovered in 1902), the colossal squid (discovered in 1925, but a full specimen not caught until 1981), and the saola (discovered in 1992) to name a few. Every year, almost 20,000 new species are described by the world's scientists, and a new book by Dr. Karl Shuker, The Encycloapedia of New and Rediscovered Animals, highlights some of the most incredible and notable new animals uncovered during the past century.
(03/12/2012) Our closest nonhuman relatives, the great apes, are in mortal danger. Every one of the six great ape species is endangered, and without more effective conservation measures, they may be extinct in the wild within a human generation. The four African great ape species (bonobos, chimpanzees and two species of gorilla) inhabit a broad swath of land across the middle of Africa, and two species of orangutans live in rainforests on the islands of Borneo and Sumatra in Southeast Asia.
(02/21/2012) There may be less birds for birders to see in the world as the planet warms. Climate change, in combination with deforestation, could send between 100 and 2,500 tropical birds to extinction before the end of century, according to new research published in Biological Conservation. The wide range depends on the extent of climate and how much habitat is lost, but researchers say the most likely range of extinctions is between 600 and 900 species, meaning about 10-14 percent of tropical birds, excluding migratory species.
(02/15/2012) Scientists have discovered four new species of super-tiny chameleons in Madagascar, according to a new paper in PLoS ONE. The smallest of the new species, Brookesia micra, is found only on the small island of Nosy Hara and has been dubbed the smallest chameleon in the world, measuring from nose to tail 29 millimeters (1.14 inches) at its largest. Scientists believe it represents a notable example of island dwarfism.
(02/07/2012) Ratu, a female Sumatra rhino (Dicerorhinus sumatrensis), is in the eleventh month of her third pregnancy raising hopes for a successful birth of one of the world's most imperiled big mammals. Ratu suffered two prior miscarriages, but researchers believe the current pregnancy—which still has four to five months to go (for a total term of around 15-16 months)—could produce what Indonesian officials have long hoped for: a bundle of joy at the Sumatran Rhino Sanctuary in Sumatra. With only around 200 Sumatran rhinos surviving today in Indonesia and Bornean Malaysia, many conservationists see such breeding efforts as the last and best chance to save the Critically Endangered species from extinction.
(02/06/2012) In 2009 researchers discovered 19,232 species new to science, most of these were plants and insects, but 148 were amphibians. Even as amphibians face unprecedented challenges—habitat loss, pollution, overharvesting, climate change, and a lethal disease called chytridiomycosis that has pushed a number of species to extinction—new amphibians are still being uncovered at surprising rates. One of the major hotspots for finding new amphibians is the dwindling tropical forests of Southeast Asia.
(01/04/2012) It may appear unintuitive that special toilets could benefit hippos and other wetland species, but the Center for Rural Empowerment and the Environment (CREE) has proven the unique benefits of new toilets in the Dunga Wetlands on Lake Victoria's Kenyan side. By building ecologically-sanitary (eco-san) toilets, CREE has managed to alleviate some of the conflict that has cropped up between hippos and humans for space.
(12/15/2011) Conservationists have often found that some cultural norms, religious beliefs, and taboos play a role in holding back traditional peoples from overusing their environment. Examples of such beliefs include days wherein one cannot hunt or fish, or certain species or regions that are off limits to exploitation. But the influence of the modern world can rapidly extinguish such beliefs, sometimes for the better, in other cases not. In many parts of Madagascar, lemurs are off the menu. These primates, found only in Madagascar, play a big role in Malagasy 'fady' or taboo-related folk stories: lemurs are protectors and, in some cases, even relatives. However, according to a new paper in PLoS ONE an influx of migrants, widespread poverty, lack domestic meat, and poor law enforcement has caused a sudden rise in eating lemurs, many of which are already near-extinction due to habitat loss.
(11/16/2011) Rats are rarely thought of as heroes. In fact, in many parts of the world they are despised, while in others they serve largely as food. But, scientists are now discovering that many tropical forest rodents, including rats, serve as heroic seed dispersers, i.e. eating fruits and nuts, and carrying seeds far from the parent tree, giving a chance to a new sapling. While this has been documented with tropical rodents in South America like agoutis and acouchis, a new study in Biotropica documents the first successful seed dispersal by an African rodent: the Kivu giant pouched rat (Cricetomys kivuensis), one of four species of giant African rats.
(11/13/2011) Many tropical plants depend on other species to carry their progeny far-and-wide. Scientists are just beginning to unravel this phenomenon, known as seed dispersal, which is instrumental in supporting the diversity and richness of tropical forests. Researchers have identified a number of animal seed dispersers including birds, rodents, monkeys, elephants, and even fish. Now a new study in the Journal of Tropical Ecology adds another seed disperser to that list: the Critically Endangered black-and-white ruffed lemur (Varecia variegata). Capable of dispersing big tree species, the black-and-white ruffed lemur may even play a big role in carbon sequestration.
(10/25/2011) In 2009 poachers shot and killed the world's last Vietnamese rhinoceros (Rhinoceros sondaicus annamiticus), a subspecies of the Javan rhino, confirms a report from International Rhino Foundation (IRF) and the World Wide Fund for Nature (WWF). The Vietnamese rhino was the last Javan rhino to survive on the Asian mainland and the second subspecies to vanish, following the extinction of the Indian Javan rhino (rhinoceros sondaicus inermis). The Javan rhino is the world's most imperiled rhino species with now only around 50 individuals surviving in a single park on its namesake island in Indonesia.
(10/06/2011) With unmistakable coloring and a philosophical, at times almost melancholy expression, the Thomas's leaf monkey (Presbytis thomasi) is one of Asia's little-known primates. Thomas's leaf monkey (also known as Thomas's langur) is found only on the island of Sumatra in Indonesia. The monkeys roam forests eating fruits and flowers, and sometimes snails, mushrooms, and coconut stalks.
(09/27/2011) Hundreds of thousands of Kenyans are supporting government efforts to enact progressive new policies through its Vision 2030 initiative as it promises to lift us out of a depressed economy and to take us onto a path to becoming a prosperous developed nation. For this to occur, development must be sustainable —but for now what the people want and need most is for the basic necessities for life to be assured like adequate water, sanitation, energy, health, education, homes, and jobs. It is unfortunate that some of our leaders are mistaken in believing that this means Kenya should look like USA or Europe with concrete cities and mega highways, speed trains, and artificial gardens—it will all be at the cost of our spectacular natural environment and wildlife heritage. Kenya hardly has any natural resources, what we have is wilderness and wildlife. For Kenya to stand apart, she must aspire to safeguard the environment and protect forests and wildlife as a central means of to attaining this sustainable development goal.
(09/11/2011) Compared to some of South America's megafauna stand-out species—the jaguar, the anaconda, and the harpy eagle come to mind—the tapir doesn't get a lot of love. This is a shame. For one thing, they're the largest terrestrial animal on the South American continent: pound-for-pound they beat both the jaguar and the llama. For another they play a very significant role in their ecosystem: they disperse seeds, modify habitats, and are periodic prey to big predators. For another, modern tapirs are some of the last survivors of a megafauna family that roamed much of the northern hemisphere, including North America, and only declined during the Pleistocene extinction. Finally, for anyone fortunate enough to have witnessed the often-shy tapir in the wild, one knows there is something mystical and ancient about these admittedly strange-looking beasts.
(09/01/2011) Given that we have very likely entered an age of mass extinction—and human population continues to rise (not unrelated)—researchers are scrambling to determine the best methods to save the world's suffering species. In the midst of this debate, a new study in Science, which is bound to have detractors, has found that setting aside land for strict protection coupled with intensive farming is the best way to both preserve species and feed a growing human world. However, other researchers say the study is missing the point, both on global hunger and biodiversity.
(08/17/2011) A groundbreaking cameratrap study has mapped the abundance, or lack thereof, of tropical mammal populations across seven countries in some of the world's most important rainforests. Undertaken by The Tropical Ecology Assessment and Monitoring Network (TEAM), the study found that habitat loss was having a critical impact on mammals. The study, which documented 105 mammals (nearly 2 percent of the world's known mammals) on three continents, also confirmed that mammals fared far better—both in diversity and abundance—in areas with continuous forest versus areas that had been degraded.
(08/08/2011) When one thinks of the world's great rainforests the Amazon, Congo, and the tropical forests of Southeast Asia and Indonesia usually come to mind. Rarely does India—home to over a billion people—make an appearance. But along India’s west coast lies one of the world's great tropical forests and biodiversity hotspots, the Western Ghats. However it's not just the explosion of life one finds in the Western Ghats that make it notable, it's also the forest's long—and ongoing—relationship to humans, lots of humans. Unlike many of the world's other great rainforests, the Western Ghats has long been a region of agriculture. This is one place in the world where elephants walk through tea fields and tigers migrate across betel nut plantations. While wildlife has survived alongside humans for centuries in the region, continuing development, population growth and intensification of agriculture are putting increased pressure on this always-precarious relationship. In a recent paper in Biological Conservation, four researchers examine how well agricultural landscapes support biodiversity conservation in one of India's most species-rich landscapes.
(06/29/2011) The Eskimo curlew is (or perhaps, 'was') a small migratory shorebird with a long curved beak, perfect for searching shorelines and prairie grass for worms, grasshoppers and other insects, as well as goodies including berries. Described as cinnamon-colored, the bird nested in the Arctic tundra of Alaska and Canada during the summer and in the winter migrated en masse as far south as the Argentine plains, known as the pampas. Despite once numbering in the hundreds of thousands (and perhaps even in the millions), the Eskimo curlew (Numenius borealis) today may well be extinct. The US Fish and Wildlife Service (USFWS) has decided to conduct a final evaluation of the species to determine whether its status should be moved from Critically Endangered to Extinct, reports Reuters.
(06/06/2011) Some conservation challenges are more daunting than others. For example, how do you save a species that has been whittled down to just a couple hundred individuals; still faces threats such as deforestation, poaching and trapping; is notoriously difficult to breed in captivity; and is losing precious time because surviving animals are so few and far-apart that simply finding one another—let alone mating and successfully bringing a baby into the world—is unlikely? This is the uphill task that faces conservationists scrambling to save the Sumatran rhino (Dicerorhinus sumatrensis). A new paper in Oryx, aptly named Now or never: what will it take to save the Sumatran rhinoceros Dicerorhinus sumatrensis from extinction? analyzes the conservation challenge, while putting forth a number of recommendations.
(05/19/2011) A new paper in Nature negating how scientists estimate extinction rates has struck a nerve across the scientific community. The new paper clearly states that a mass extinction crisis is underway, however it argues that due to an incorrect method of determining extinction rates the crisis isn't as severe as has been reported. But other experts in the field contacted disagree, telling mongabay.com that the new the paper is 'plain wrong'. In fact, a number of well-known researchers are currently drafting a response to the day-old, but controversial paper.
(05/12/2011) Despite decades of conservation work, populations of North America's smallest turtle, the bog turtle (Glyptemys muhlenbergii), is continuing to decline. Habitat destruction, invasive plants, road-kill, and the illegal pet trade have all played a role in the bog turtle historic decline, but researchers are now reporting increased mortalities across bog turtle populations, bringing fears of disease or an as-yet-unnamed environmental issue.
(05/11/2011) Few animals face as violent, as well organized, and as determined an enemy as the world's rhinos. Across the globe rhinos are being slaughtered in record numbers; on average more than one rhino is killed by poachers everyday. After being shot or drugged, criminals take what they came for: they saw off the animal's horn. Used in Traditional Chinese Medicine, which claims that it has curative properties, rhino horn is worth more than gold and cocaine on the black market. However, science proves all this cash and death is based on a lie. 'There is no medicinal benefit to consuming rhino horn. It has been extensively analyzed in separate studies, by different institutions, and rhino horn was found to contain no medical properties whatsoever,' says Rhishja Larson.
(05/09/2011) It's not easy to find a single word to describe witnessing hundreds of thousands of flamingos filling up a shallow lake in the Great Rift Valley of East Africa. 'Spectacle' comes to mind, but even this is not wholly accurate for the surreal pink crowd. However one describes it, this biological wonder may be under threat as Tanzania plans to mine in a flamingo breeding ground that is not only regionally important, but globally. Astoundingly, over half of the world's lesser flamingos (between 65-75%) are born in a single lake in northern Tanzania: Lake Natron.
(05/01/2011) Imagine visiting a region that is largely void of tourists, yet has world-class bird watching, a unique Buddhist population, and one of the world's most bizarre-looking and imperilled mammals: the saiga. A new tour to Southern Russia hopes to aid a Critically Endangered species while giving tourists an inside look at a region "largely forgotten by the rest of the world," says Anthony Dancer. Few species have fallen so far and so fast in the past 15 years as Central Asia's antelope, the saiga. Its precipitous decline is reminiscent of the bison or the passenger pigeon in 19th Century America, but conservationists hopes it avoids the fate of the latter.
(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.
(02/24/2011) Krithi Karanth grew up amid India's great mammals—literally. Daughter of conservationist and scientist Dr. Ullas Karanth, she tells mongabay.com that she saw her first wild tigers and leopard at the age of two. Yet, the India Krithi Karanth grew up in may be gone in a century, according to a massive new study by Karanth which looked at the likelihood of extinction for 25 of India's mammals, including well-known favorites like Bengal tigers and Asian elephants, along with lesser known mammals (at least outside of India) such as the nilgai and the gaur. The study found that given habitat loss over the past century, extinction stalked seven of India's mammals especially: Asiatic lions, Bengal tigers, wild dogs (also known as dholes), swamp deer, wild buffalo, Nilgiri Tahr, and the gaur. However, increasing support of protected areas and innovative conservation programs outside of parks would be key to saving India's wildlife in the 21st Century.
(02/23/2011) Surviving hundreds of millions of years on Earth have not saved turtles from facing extinction at human hands. A new report by the Wildlife Conservation Society (WCS) and the Turtle Conservation Coalition, identifies the world's 25 most imperiled turtles, including one that is practically assured extinction: 'Lonesome George' the last Abdington Island tortoise in the world. The list includes four turtle species from South and Central America, three from Africa, and one from Australia. But Asia is the hotbed for turtles in trouble with 17 of the top 25 species, or 68%. The numbers are even more alarming if one looks only at the top ten: eight of the top ten are in Asia, and six of these in China.
(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.
(02/16/2011) Last August, a group of conservation agencies launched the Search for Lost Frogs, which employed 126 researchers to scour 21 countries for 100 amphibian species, some of which have not been seen for decades. After five months, expeditions found 4 amphibians out of the 100 targets, highlighting the likelihood that most of the remaining species are in fact extinct; however the global expedition also uncovered some happy surprises. Amphibians have been devastated over the last few decades; highly sensitive to environmental impacts, species have been hard hit by deforestation, habitat loss, pollution, agricultural chemicals, overexploitation for food, climate change, and a devastating fungal disease, chytridiomycosis. Researchers say that in the past 30 years, its likely 120 amphibians have been lost forever.
(01/27/2011) The big mammals for which Africa is so famous are vanishing in staggering numbers. According to a study published last year: Africa's large mammal populations have dropped by 59% in just 40 years. But what is even more alarming was that the study only looked at mammal populations residing in parks and wildlife areas, i.e. lands that are, at least on paper, under governmental protection. Surveying 78 protected areas for 69 species, the study included global favorites such as the African elephant, giraffes, zebra, wildebeest, and even Africa's feline king, the lion. "We weren’t surprised that populations had dropped but we were surprised by how large the drops had been," lead author Ian Craigie told mongabay.com in an interview.
(11/22/2010) Classified as Critically Endangered by the IUCN Red List, listed among the Top 25 Most Endangered primates in the world, and rated number 71 on the EDGE's list of world's most endangered and unique mammals, the yellow-tailed woolly monkey needed some good news—and this week it got it. The conservation organization, Neotropical Primate Conservation (NPC), has announced the discovery of an unknown population of the yellow-tailed woolly monkey (Oreonax flavicauda), buttressing hopes that the species will survive in the long-term.
(11/21/2010) What do the New Zealand greater short-tailed bat, the black-and-white ruffed lemur, and the numbat have in common? They are all new members of the Zoological Society of London's EDGE top 100 most endangered and unique mammals list. Arguably the most innovative conservation program in the world, EDGE decides which species to focus conservation efforts on not based on popularity or fund-raising potential, but on hard data, only working with species that are considered the most endangered and evolutionarily distinct.
