The Panamanian golden frog declared extinct by BBC Natural History crew
(2/4/2008) A national symbol of Panama has been declared extinct by BBC filmmakers. The crew was in Panama to film the unique frog for David Attenborough's most recent series on reptiles and amphibians, entitled Life in Cold Blood. The filmmakers achieved their objective and captured the golden frog on film, including rarely seen behavior.


Giant shrew discovered in Tanzania
(2/1/2008) More than a quarter larger than all of its relations, the Grey-faced sengi (Rhynchocyon udzungwensis) was first discovered on a roll of film from camera traps set-up in the Udzungwa Mountains of Tanzania. The photos of this mysterious giant elephant-shrew were sent to expert Dr. Galen Rathbun, who has studied the sengi (or elephant-shrew) for over thirty years; after examiining the photos he believed that the animal's unique coloring proved it was an unknown species.


Arctic wolves caught on tape displaying new hunting behavior
(1/31/2008) The BBC Natural History unit has captured footage of the Artic wolf swimming for its meal. The camera crew were filming a documentary entitled White Falcon, White Wolf on Ellesmere Island, a part of the Canadian territory of Nunavut, when they spotted this never-before-seen behavior.


New research refutes global warming's influence on amphibians' worst enemy
(1/30/2008) There is no doubt that global warming is having a negative effect on amphibians, but it is yet unclear whether or not a direct causal relationship exists between global warming and the spread of a specific fungal epidemic wreaking havoc on amphibian populations worldwide.


Photos: Top 100 most threatened amphibians named
(1/21/2008) Due to numerous factors--including habitat destruction, pollution, climate change, and chytrid fungus--amphibians are probably the most threatened taxon of species in the world. Dr Jonathan Baillie, head of the EDGE organization which has just established an amphibian program, stated that "tragically, amphibians tend to be the overlooked members of the animal kingdom, even though one in every three amphibian species is currently threatened with extinction, a far higher proportion than that of bird or mammal species." To help save these species on the brink, EDGE, apart of the Zoological Society of London, has compiled a list of the hundred most threatened and evolutionary distinct amphibians.


Border fence may drive largest American cat to extinction
(1/21/2008) The Bush Administration's decision to not prepare a recovery plan for the endangered jaguar in its native habitat in Arizona and New Mexico may spell the end for the big cat in the United States, says an environmental group.

(1/20/2008) "Midget" is the youngest member of a family (six in all) of douroucoulis at the Bronx Zoo's World of Darkness. The only true nocturnal monkey, this species is also known as "owl monkey" or "night monkey".


Two-thirds of carnivores die when reintroduced into the wild
(1/20/2008) Carnivores reintroduced to the wild as part of conservation programs fare poorly, reports a new study published online in the journal Biological Conservation.


To reproduce, parasite transforms ant into juicy red berry
(1/17/2008) Scientists have discovered a parasite that transforms the appearance of its host, an ant, into that of a juicy red berry that birds are more likely to eat and disperse into new habitats, reports an article published in The American Naturalist. It is the first example of fruit mimicry caused by a parasite, say the researchers who discovered the parasite, a nematode or roundworm found in the canopy of tropical forests ranging from Central America to the lowland Amazon.

An interview with primate researcher Dr. Karen Strier: America's largest monkey recovering after brush with extinction
(1/10/2008) The Atlantic forest of Brazil boasts South America's largest primates, the Southern and Northern Muriqui. The muriqui are unique among all primates, because they are not territorial and do not display aggressive behavior. The IUCN has classified the Southern Muriqui as endangered, while the Nothern Muriqui is critically endangered. Dr. Karen Strier has studied the Northern Muriqui in the field for twenty-five years. A professor of zoology and anthropology at the University of Madison Wisconsin, she is the author of Faces in the Forest: the Endangered Muriqui Monkeys of Brazil and a new textbook entitled Primate Behavioral Ecology.


Dirt-munching helps protect chimps from malaria
(1/10/2008) Soil ingestion helps chimps protect themselves from malaria, reports a new study published in the journal Naturwissenschaften. Apparently geophagy, as the deliberate behavior is known, increases the potency of ingested plants with anti-malarial properties.


Disappearance of elephants, giraffes causes ecological chain reaction
(1/10/2008) The disappearance of elephants, giraffes and other grazing animals from the eastern African savanna could send ecological ripple effects all the way to the savanna's ants and the acacia trees they inhabit, warns a new study published in the journal Science.


Male lion licking a female's head
(1/8/2008) Bronx Zoo's newest lions, male M'wasi and female Sukari, have recently been introduced on the Zoo's Africa Plains. A typical lion greeting is quick, lasting less than a minute, and includes touching heads.


Photos: Hippos threatened in Africa
(1/7/2008) As the sun sets on the Luangwa River in Zambia, a male hippo throws its mouth open in a yawn as wide as a canyon. Night is falling as the hippo herds break to the banks to follow their regular paths to their feeding grounds. Their huge, round hooves made muddy imprints during the rainy season, and have dried to concrete craters along a trail the hippos follow to graze in grassy glades.


Three salamander species discovered in Costa Rica
(1/6/2008) Scientists from the Natural History Museum of London have discovered three new species of salamander in south-eastern Costa Rica. This brings the nation's total to forty-three species, meaning that this small tropical nation contains approximately nine percent of the world's salamanders.

Orangutan should become symbol of palm-oil opposition
(1/2/2008) In a letter published today in Nature, Oscar Venter, Erik Meijaard and Kerrie Wilson argue that proposals for conservation groups to purchase and run oil palm plantations for the purpose of generating funds for forest protection are unlikely to be successful. The concept was originally put forth by Lian Pin Koh and David S. Wilcove in a 2007 Nature article.


As amphibians leap toward extinction, alliance pushes "The Year of the Frog"
(12/31/2007) With amphibians experiencing dramatic die-offs in pristine habitats worldwide, an alliance of zoos, botanical gardens and aquariums has launched a desperate public appeal to raise funds for emergency conservation measures. Scientists say that without quick action, one-third to one-half the world's frogs, toads, salamanders, newts and caecilians could disappear.


6 species of giraffe "discovered"
(12/21/2007) Genetic analysis that the world's tallest animal--the giraffe--may actually be several species, according to a study published in the open access journal BMC Biology. Existing taxonomy recognizes only one species of giraffe.


Squirrels use snake skin to disguise themselves from predators
(12/20/2007) California ground squirrels and rock squirrels chew up rattlesnake skin and smear it on their fur to mask their scent from predators, according to a new study by researchers at UC Davis. Barbara Clucas, a graduate student in animal behavior at UC Davis, observed ground squirrels (Spermophilus beecheyi) and rock squirrels (Spermophilus variegates) applying snake scent to themselves by picking up pieces of shed snakeskin, chewing it and then licking their fur.


Evolution of whales challenged
(12/19/2007) Modern whales appear to have evolved from a raccoon-sized creature with the body of a small deer, according to scientists writing in the journal Nature. The results challenge the theory that cetaceans are descended from even-toed ungulates (artiodactyls) like hippos, as previous molecular analysis has suggested.


Migrating frogs fare poorly when habitat altered

Photos: Two unknown mammal species discovered in "lost world"
(12/16/2007) Two mammal species -- a tiny possum and a giant rat — discovered on a recent expedition to Indonesia's remote Foja Mountains in New Guinea are likely new to science, report researchers from Conservation International (CI) and Indonesia Institute of Science (LIPI). The area won international fame after a December 2005 survey turned up dozens of new species and gave urgency to conservation efforts in a region where logging and forest clearing for agriculture are a serious concern.


Threatened birds may be rarer than previously thought, finds study
(12/11/2007) Geographic range maps that allow conservationists to estimate the distribution of birds may vastly overestimate the actual population size of threatened species and those with specific habitats, according to a study published online this week in the journal Conservation Biology.


Traffic cones used to protect seabirds
(12/11/2007) Bright orange traffic cones that warn drivers of danger on the road are now being used to steer seabirds away from deadly entanglement in fishing nets, the Wildlife Conservation Society (WCS) reports. Argentinean marine biologist and inventor Diego Gonzalez Zevallos has conducted research funded by WCS and Fundacion Patagonia National on the issue for over five years.


Photos: Elusive long-eared jerboa caught on film for the first time
(12/10/2007) Extraordinary footage of the endangered long-eared jerboa was taken by scientists from the EDGE; this is the first time the jerboa, a hopping rodent that sports massive ears, has ever been caught on film.

Global warming will significantly increase bird extinctions
(12/6/2007) Where do you go when you've reached the top of a mountain and you can't go back down? It's a question increasingly relevant to plants and animals, as their habitats slowly shift to higher elevations, driven by rising temperatures worldwide. The answer, unfortunately, is you can't go anywhere. Habitats shrink to the vanishing point, and species go extinct. That scenario is likely to be played out repeatedly and at an accelerating rate as the world continues to warm, Stanford researchers say.


Rare gorillas use weapons to attack forest-intruding humans
(12/5/2007) Following the first documented cases of the Cross River gorillas -- world's most endangered gorilla -- throwing sticks and clumps of grass when threatened by people, the Wildlife Conservation Society (WCS) has announced new research to better protect the species from poaching and encroachment.


Piranhas originated when Amazon was flooded by seawater
(12/4/2007) South America's piranha family of fish -- notorious as eaters of flesh -- can be traced back to a single ancestor which dispersed when the Amazon was flooded by seawater some five million years ago, report researchers from the Institut de Recherche Pour le Développement (IRD). Today piranhas are exclusively freshwater fish found from the Orinoco River basin in Venezuela to the Paraná in Argentina.


Earthquake triggers decline in a frog species
(12/3/2007) In 1999 a 7.3 earthquake struck Nantou County at the center of quake-prone Taiwan. The earthquake caused considerable damage: over 2,000 people died and just under 45,000 houses were destroyed. It was Taiwan's strongest quake in a hundred years. The quake also devastated a subpopulation of riparian frogs, Rana swinhoana, which had been under scientific study for three years prior. This devastation allowed scientists the opportunity to study the population changes in a species affected suddenly and irretrievably by natural disaster.


25% of American birds threatened
(11/29/2007) More than one quarter of the bird species found in the United States are imperiled, reports a new survey by the National Audubon Society and the American Bird Conservancy. Overall 178 species in the continental U.S. and 39 in Hawaii are listed on WatchList 2007, which is based on a comprehensive analysis of population size and trends, distribution, and threats for 700 bird species in the U.S.

86% of sea turtle species threatened with extinction
(11/14/2007) Marine turtles have thrived for more than 100 million years. But only the last few hundred years have given the huge, spectacular, prehistoric amphibians serious trouble.


Sun Bears reclassified by IUCN as Vulnerable
(11/13/2007) The world's smallest bear has been recently classified as vulnerable by the IUCN due to habitat loss and poaching. Co-chair of the IUCN Bear Specialist Group, Dave Garshelis, states that "although we do not have any reliable population estimates for the sun bear, or any of the other Asian bears for that matter, we fear that bears in Southeast Asia are declining at a particularly rapid rate due to extensive loss of forest habitat combined with rampant poaching."


Conservationist Schaller named to Time's 'Hero of the Planet'
(11/13/2007) Renowned conservationist Dr. George Schaller of the Wildlife Conservation Society was recently named by Time Magazine as one of 60 'Heroes of the Planet.'
