Rainforest fragmentation affects reptiles and amphibians

(02/20/2008) Deforestation of tropical ecosystems is one of the major threats to biological diversity. Anthropogenic activities transform tropical environments into semi-natural landscapes generating a great amount of forest edge that limits with pastures and agricultural lands.


Gecko-inspired adhesive tape could improve recovery from surgery

(02/18/2008) Researchers are close to developing a biodegradable surgical adhesive based on biomimicry of gecko feet. Geckos are famous for their ability to walk on ceilings and vertical surfaces.


Madagascar's tortoises at high risk of extinction

(02/07/2008) Madagascar's rare and unique turtles and tortoises face high risk of extinction in the wild if conservation measures are not rapidly put into place, warned a group of scientists meeting to discuss the fate of Madagascar's most threatened repitles.


Sea turtle makes record migration - 12,774 miles

(02/07/2008) Satellite-tagging has revealed that a leatherback sea turtle (Dermochelys coriacea) swam a total distance of 20,558 kilometers (12,774 miles) over 647 days from Jamursba-Medi, Indonesia to the coast of Oregon. The results are published in The State of the World's Sea Turtles magazine, a publication launched by conservation International and the IUCN Marine Turtle Specialist Group.


Scientists discover four species of anole lizards in 24 hours in Panama

(01/13/2008) In January of 2006 a biological expedition uncovered four anole species in a single day. Dr. Gunther Koehler, a member of the expedition, described the discoveries as "a once in a life time experience; during expeditions before, we had found new species, one at a time--but four species within 24 hours, that was incredible!"


Study shows that sea turtles can recover

(12/18/2007) conservation of sea turtle nesting sites is paying off for the endangered reptiles, reports a new study published this week in the journal Global Ecology and Biogeography. A team of researchers led researchers from IUCN and conservation International found that green turtle (Chelonia mydas) nesting on four beaches in the Pacific and two beaches in the Atlantic have increased by an four to fourteen percent annually over the past two to three decades as a result of beach protection efforts.


World's largest spitting cobra discovered in Kenya

(12/09/2007) The world's largest spitting cobra has been discovered in Kenya, according to WildlifeDirect, a conservation group.


Photo of the Venomous Gila Monster Getting an X-ray

(11/28/2007) Dr. Tim Georoff, a veterinarian for the Wildlife conservation Society's Bronx Zoo, handles this venomous lizard with great care as he prepares this female for an radiograph (X-ray).


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.


Iguanas listen to birds to avoid predators

(10/29/2007) As the world's only sea-feeding lizard, Galapagos Marine Iguanas have long held a unique place in the animal kingdom. While most of their life is spent on land, these lizards forage the seas for their staple food: algae. Now, new research has provided this species with another distinction: although the Galapagos Marine Iguana is mute, it recognizes and utilizes the alarm call of the Galapagos Mockingbird. This is the first instance of a non-vocal species eavesdropping on another species' calls. Both the iguana and mockingbird fall prey to the Galapagos hawk, so by recognizing the mockingbird's warning the iguanas gain important information on avoiding predation.


Mexican fishing villages work to change practices to preserve loggerhead turtles

(10/17/2007) Industrial fishing operations take plenty of blame for both depleting fish stocks and inadvertently catching innocent bystanders such as dolphins, sharks, seabirds, and sea turtles--a phenomenon known as "bycatch.".


How do snakes survive starvation?

(08/27/2007) Starving snakes employ novel survival strategies not seen before in vertebrates, according to research conducted by a University of Arkansas biologist. These findings could be used in conservation strategies to determine the health of snake populations.


Legless lizard retracts eyes to avoid retaliatory prey bites

(08/14/2007) For creatures without legs, snakes are remarkable predators. Pythons can capture and eat animals well over twice their size, while a mere drop of venom injected by an Australian death adder can kill a person. Scientists believe the main purpose for these adaptations is to help snakes avoid injury when pursuing and eating prey. However, snakes are not the only legless reptiles -- there are more than a dozen species of legless lizard distributed around the world. A new paper examines how these reptiles subdue their prey without venom or constriction.


Squirrels communicate with rattlesnakes using heated tail

(08/13/2007) Ground squirrels heat their tails to defend their young against predatory rattlesnakes, reports a study published in the early online edition of Proceedings of the Natural Academy of Sciences (PNAS).


Gecko + mussels = biomimetic underwater adhesive

(07/19/2007) Scientists have developed a new adhesive material based on the properties of mussels and gecko lizard. The researchers say the biomimetic design could produce more durable and longer-lasting bandages, patches, and surgical materials.


Forest disturbance reduces biodiversity in the Amazon rainforest

(07/02/2007) Two new studies in the Amazon rainforest show that plantation forests and second-growth forests have lower species counts for butterflies, reptiles, and amphibians than adjacent primary forest areas. The research has important implications for conservation of tropical biodiversity in a world where old-growth forest is increasingly replaced by secondary forests, industrial plantations, and agricultural landscapes.


Mother lizards select color patterns of offspring

(06/13/2007) Mother lizards can induce different color patterns in their offspring in response to social cues, reports research published June 10 in the online early edition of the journal Ecology Letters. Female side-blotched lizards determine the patterns "most likely to ensure success under the conditions they will encounter as adults," according to scientists from the University of California, Santa Cruz.


New snake-like lizard discovered in India

(05/28/2007) A previously unknown species of legless lizard as been discovered in a remote Indian forest, reports the Associated Press. Sushil Kumar Dutta, leader of a team of researchers from NGO Vasundhra and the North Orissa University, found the 7-inch long creature in the forests of Khandadhar near Raurkela in Orissa state, about 625 miles southeast of New Delhi.


Rare softshell turtle rediscovered in Cambodia

(05/16/2007) Scientists from conservation International have successfully hatched a clutch of eggs from one of the world's most endangered turtle species.


Sex differences fuel evolution

(05/10/2007) Some Caribbean lizards' strong sexual dimorphism allows them to colonize much larger niches and habitats than they might otherwise occupy, allowing males and females to avoid competing with each other for resources and setting the stage for the population as a whole to thrive. The finding, reported this week in the journal Nature, suggests sex differences may have fueled the evolutionary flourishing of the Earth's wildly diverse fauna in a way not previously appreciated by scientists.


Animals on islands more abundant than mainland

(04/30/2007) A comprehensive survey of lizards on islands around the world has confirmed what island biologists and seafaring explorers have long observed: Animals on islands are much more abundant than their counterparts on the mainland.


Stephen Colbert's sea turtle second in race to Galapagos

(04/25/2007) Nearing the end of Great Turtle Race, Stephen Colbert's sea turtle Stephanie Colburtle was in second place, 18 miles behind Billie, a turtle sponsored by Offield Center for Billfish Studies. Billie is just 31 miles from the finish line of the 500-mile race.


Stephen Colbert's sea turtle currently third in race

(04/19/2007) On the fourth day of the Great Turtle Race, 3 of the leatherback turtles have completed Stage One, passing the 200-mile marker of the 500-mile race from Costa Rica to the Galapagos. The Great Turtle Race is a unique sea turtle conservation event that has engaged tens of thousands of adults and children around the world since it began on April 16.


Neon green gecko key to preventing Mauritian plant extinction

(04/17/2007) A vibrantly colored gecko plays a key role in a highly threatened ecological community in Mauritius reports new research published in American Naturalist. Studying plant-animal interactions in Mauritius, an Indian Ocean island famous for its extinct dodo bird, researchers found that a rare plant, Trochetia blackburniana, benefits from its proximity to Pandanus plants because they house high densities of geckos responsible for pollination. The findings, which unusually identify a lizard as a key pollinator, are significant because they provide "valuable management insights for ongoing conservation efforts to save the highly endangered flora of Mauritius.


Bad news for frogs; amphibian decline worse than feared

(04/16/2007) Chilling new evidence suggests amphibians may be in worse shape than previously thought due to climate change. Further, the findings indicate that the 70 percent decline in amphibians over the past 35 years may have been exceeded by a sharp fall in reptile populations, even in otherwise pristine Costa Rican habitats. Ominously, the new research warns that protected areas strategies for biodiversity conservation will not be enough to stave off extinction. Frogs and their relatives are in big trouble.


Racing sea turtle named in honor of Stephen Colbert

(04/13/2007) An eleventh turtle named Stephanie Colburtle has joined competitors Yahoo!, Travelocity, Plantronics, West Marine, Dreyer's Ice Cream and other sponsors in The Great Turtle Race, a unique international sea turtle conservation event that will take place online from April 16 to April 29 in a global bid to raise awareness and funds for the critically endangered leatherback turtle.


Pythons turn bones of prey into calcium

(04/01/2007) Burmese pythons don't eat very often, but when they do they like to pig out, ingesting the whole of their prey. There's very little waste as they are able to digest everything, apart from hair and feathers. Dr Jean-Herv Lignot (Louis Pasteur University) and Dr Robert K. Pope (Indiana University South Bend) will talk about the implications this has on the way these snakes digest food on Saturday 31st March at the Society for Experimental Biology's Annual Meeting in Glasgow.


Evolutionary precursor to snake discovered

(03/23/2007) A University of Alberta paleontologist has helped discover the existence of a 95 million-year-old snakelike marine animal, a finding that provides not only the earliest example of limbloss in lizards but the first example of limbloss in an aquatic lizard.


Prehistoric lizard glided through air using ribs

(03/19/2007) An extinct species of lizard used a wing-like membrane supported by the animal's elongated ribs for gliding through the air according to Chinese researchers. The 6-inch (15.5 cm) lizard, found in the Liaoning Province of northeastern China, lived during the Early Cretaceous period. The specimen is described in the early online edition of the journal Proceedings of the National Academy of Sciences (PNAS).


World's only blue lizard heads toward extinction

(03/07/2007) High above the forest floor on the remote Colombian island of Gorgona lives a lizard with brilliant blue skin, rivaling the color of the sky. Anolis gorgonae, or the blue anole, is a species so elusive and rare, that scientists have been unable to give even an estimate of its population. Due to the lizard&spod;s isolated habitat and reclusive habits, researchers know little about the blue anole, but are captivated by its stunning coloration.


Sea turtles use Earth's magnetic field to return to nesting beaches

(02/27/2007) New research suggests that sea turtles use a 'relatively simple navigation system' involving the Earth's magnetic field to return to the same beaches to lay their eggs, even after venturing across thousands of miles of open ocean without visible landmarks.


Doctor performs kidney surgery on egg-eating snake

(02/22/2007) In early February Dr. Robert Moore performed microsurgery on an adult African egg-eating snake at the Bronx Zoo's Animal Health Center.


Blind pink snake discovered in Madagascar

(02/14/2007) A pink worm-like snake has been rediscovered in Madagascar more than 100 years after it was first found. The snake, which is blind and measures about ten inches long, is described in the February 1, 2007 edition of Zootaxa, a leading taxonomic journal.


Snake becomes poisonous by eating toxic frogs

(01/29/2007) A new study shows that the Asian snake Rhabdophis tigrinus becomes poisonous by sequestering toxins from its prey which consists of venomous toads. While sequestering defensive toxins from prey is unusual among terrestrial vertebrates it is not unknown. Research published last year by Valerie C. Clark of Cornell University showed that poison dart frogs (Dendrobates species) and their Madagascar counterparts, the Mantella frogs, sequester toxic skin chemicals, called alkaloids, from the ants they eat. These alkaloids protect the frogs from predation. Similarly, some garter snakes are known to store tetrodotoxin from ingested newts while birds in New Guinea appear to sequester poisons from insects.


5 Komodo Dragons Hatch at British Zoo

(01/24/2007) Five immaculately conceived Komodo dragons hatched at the Chester Zoo in northern England. Scientists say the birth could have conservation implications for the endangered species of reptile.


Two 'dragon' species discovered in Brazil

(01/24/2007) Two previously unknown species of lizard that are said to resemble miniature ground-dwelling dragons have been found in the threatened cerrado region of Brazil. The species, Stenocercus squarrosus and Stenocercus quinarius are described in the current issue of the South American Journal of Herpetology.


China uses snake-based earthquake prediction system

(12/27/2006) A province in southern China has come up with a unique way to predict earthquakes: snakes. According to China Daily and as reported by Reuters, the earthquake bureau in Nanning, capital of the Guangxi province, has set up a 24-hour video feed to monitor the behavior of snakes at snake farms. The scientists say that snakes are particularly sensitive to vibrations caused by impending earthquakes.


Virgin dragon to give birth this Christmas

(12/20/2006) A virgin Komodo dragon will give birth to offspring this Christmas (or thereabouts) at the Chester Zoo in Britain according to researchers. Flora, a female Komodo dragon, will reproduce asexually in a process called parthenogenesis, where eggs become embryos without male fertilization. The process is known to occur in about 70 reptile species but hadn't been observed in Komodo dragons -- the world's largest lizard species -- until this year. Another dragon, Sungai, had virginal conception earlier this year. Both cases are described in Thursday's issue of the journal Nature


Farmers fight FDA over pet turtle ban

(10/04/2006) Farmers are battling the FDA over the legality of turtles that were once commonly kept as pets according to an article in today's issue of The Wall Street Journal.


The science behind 'Snakes on a Plane'

(08/07/2006) Even in the dark, snakes on a plane could keep a close watch on terrorized passengers and crew thanks to small cavities near their snouts known as pit organs, according to a forthcoming article by Andreas B. Sichert, Paul Friedel, and J. Leo van Hemmen published in Physical Review Letters.


Venomous snakes key to human evolution says new theory

(07/21/2006) The ability to spot venomous snakes may have played a major role in the evolution of monkeys, apes and humans, according to a new hypothesis by Lynne Isbell, professor of anthropology at UC Davis. The work is published in the July issue of the Journal of Human Evolution.


Color-changing chameleon snake discovered in jungles of Borneo

(06/27/2006) Scientists discovered a species of snake capable of changing colors. The snake, called the Kapuas mud snake, resides in the rainforest on the island of Borneo, an ecosystem that is increasingly threatened by logging and agricultural development.


Rare Chinese alligators sent to China

(05/17/2006) The U.S. made a slight dent in the trade deficit today when a dozen rare Chinese alligators were shipped from the Wildlife conservation Society's (WCS) headquarters at the Bronx Zoo directly to China, as part of an international effort to restore populations of these highly endangered reptiles


Lizard gives clues on evolution of eye

(04/14/2006) Lizards have given Johns Hopkins researchers a tantalizing clue to the evolutionary origins of light-sensing cells in people and other species. The lizard study describes how the lizard's so-called third, or parietal, eye, distinguishes two different colors, blue and green, possibly to tell the time of day. Specialized nerve cells in that eye, which looks more like a spot on the lizard's forehead, use two types of molecular signals to sense light: those found only in simpler animals, like scallops, and those found only in more complex animals like humans. Although the blue-green color comparison method used by the parietal eye is not one shared by humans, it does reveal one potential step in the evolution of color vision, the Hopkins researchers say. The proponents of intelligent design assert that the combination of nerves, muscles, sensory cells, and lens tissue in the eye could only have been 'designed' from scratch but this new research gives new insight into the evolutionary development of light-sensing cells, key to the eventual development of eye-like structures and color vision.


Male lizard color may result from female preference

(12/27/2005) The anole lizard's dewlap -- a flap of skin that hangs beneath its chin -- plays an important role in species recognition, territorial defense and courtship. According to the Smithsonian Tropical Research Institute (STRI), a leading research institution in Panama, male slender anoles (Norops limifrons) exhibit variation in dewlap color ranging from orange dewlaps in Gamboa populations, white with an orange spot on Barro Colorado Island, and mixed populations in Soberania.


Python explodes after swallowing 6-foot alligator in Florida Everglades

(10/05/2005) The National Park Service released photos that show the carcass of an American alligator that was almost swallowed by a Burmese python.


Microchip implant saves endangered turtle from the cooking pot

(07/18/2005) An extremely rare "royal" turtle narrowly escaped a trip to a Chinese soup-pot, thanks to a tiny microchip implanted in its skin, according to experts from the New York-based Wildlife conservation Society (WCS), who rediscovered the species four years ago in Cambodia.
