(02/17/2014) Scientists have identified a new species of day gecko that is the largest in its genus (Cnemaspis) to be found in Sri Lanka. To date, it has been observed only within the Rammalakanda Reserve in southern Sri Lanka, an area spanning just 1,700 hectares, raising questions about the viability of this population and hence the species' long-term prospects.
Next big idea in forest conservation? Incentivizing keeping primary forests intact
(02/07/2014) Much of Dr. Corey Bradshaw's work has a singular aim: to keep primary habitats and functioning ecosystems intact. According to Bradshaw, the existing system of carbon trading rules needs to be changed so that primary forests are given a higher value than other forms of land use. 'Nothing, can replace primary vegetation, both in terms of biodiversity value and other ecosystem services.'
One lizard, four species: the collared treerunner
(01/21/2014) Now, that’s a horse of a different color. Or, in this case, a lizard of another species--four species. Recent research suggests that the collared treerunner (Plica plica), previously thought of as one widespread species, is actually four distinct species inhabiting diverse geographical areas east of the Andes in northern South America.
Microhabitats could buffer some rainforest animals against climate change
(11/25/2013) As temperatures increase worldwide due to anthropogenic climate change, scientists are scrambling to figure out if species will be able to survive rapidly warming ecosystems. A new study in Global Change Biology offers a little hope. Studying reptiles and amphibians in the Philippines, scientists say some of these species may be able to seek refuge in cooler microhabitats, such as tree holes or under the soil, in order to stay alive during intensifying heatwaves. But, the scientists' stress, the shelter from microhabitats can only protect so far.
Critically Endangered Jamaican iguana imperiled by port development
(11/08/2013) The story of the Jamaican iguana (Cyclura collie) is one of adversity and resurgence. Once believed extinct, the species has made a remarkable comeback over the last two decades. However, according to concerned scientists, a new plan to build a massive port in the iguana's habitat could push the species back to the edge of extinction.
Scientists identify individual lizards by their irises
(10/29/2013) Institutions and governments have been scanning human irises for years to verify one's identity—Google has been using this method since 2011—but could iris-scanning be employed on other species as well? According to a new study in Amphibia-Reptila, the answer is 'yes.' Scientists have recently employed iris scanning to visually distinguish individuals of an imperiled gecko subspecies (Tarentola boettgeri bischoffi) found on Portugal's Savage Islands off the coast of Western Sahara. l.
New to science: 2 lizards, 1 frog discovered on Australian expedition (pictures)
(10/28/2013) Researchers from James Cook University and National Geographic discovered three new herp species — a cryptic leaf-tail gecko, a colorful skink, and a frog — during an expedition to northeastern Australia. The species are described in three papers published in October in the journal Zootaxa.
4 new species of legless lizards discovered in California

The iguana man: saving the reptilian kings of the Bahamas
(08/01/2013) Before the arrival of humans—with their dogs, cats, and wild pigs—the northern Bahamian rock iguana ruled its home range, being pound-for-pound among the biggest land animals on the islands. In these ecosystems, the iguana's were the mega-grazers, the bison and elk of the Caribbean one might say. But hunting by humans, invasive species, and habitat loss knocked the king from its throne: pushing it into smaller habitats and decimating its population. Today the three subspecies of the northern Bahamian rock iguana (Cyclura cychlura) hang by a thread. And now a new threat is rising: poorly-regulated tourism, including iguana feeding.
Dominican Republic sends bulldozers to destroy wildlife reserve, home to endangered species
(07/23/2013) Last Wednesday, bulldozers entered the Loma Charco Azul Biological Reserve (LCABR) in the Dominican Republic and began clearing vegetation for agricultural development. The move stunned local conservationists who had not been notified ahead of time of the project. Although Charco Azul Biological Reserve is home to a wealth of threatened species—including the world's largest population of the Critically Endangered Ricordi's iguana (Cyclura ricordi)—the destruction of the reserve was signed off by the Dominican Republic's Minister of the Environment, Bautista Rojas Gómez.
Monitor lizards vanishing to international trade in pets and skins
(06/04/2013) The world's monitor lizards remind us that the world was once ruled by reptiles: this genus (Varanus) includes the world's biggest lizards, such as the stunning Komodo dragon and many other island kings. A large number beautifully-colored and patterned, these lizards are known for their intelligence and their apex role in many island food chains. However, a new study finds that the world's monitors, especially those in Southeast Asia, are vanishing due to the international pet trade and for their skins, which are turned into handbags and straps for watches. Meanwhile the rapid destruction of their rainforest homes is exacerbating the situation.
Market figures out that geckos don't cure AIDS, but killing continues
(04/12/2013) Millions of tokay geckos continue to be traded for traditional medicine, despite waning belief that the colorful lizards are a cure for AIDS, reports a new study from TRAFFIC.
Madagascar's chameleons came from African mainland

Indonesia remains epicenter for illegal wildlife trade in reptiles and amphibians
(10/24/2012) Demand for exotic pets is driving the illegal harvest and trade of herpetofauna (reptiles and amphibians) in Indonesian New Guinea, according to a recent study published in the journal Biodiversity and Conservation. Between September 2010 and April 2011, Daniel Natusch and Jessica Lyons of the University of New South Wales surveyed traders of amphibians and reptiles in the Indonesian provinces of Maluku, West Papua and Papua.
Remarkable comeback: blue iguana downgraded to Endangered after determined conservation efforts
(10/23/2012) The wild blue iguana population has increased by at least 15 times in the last ten years, prompting the IUCN Red List to move the species from Critically Endangered to just Endangered. A targeted, ambitious conservation program, headed by the Blue Iguana Recovery Team, is behind this rare success for a species that in 2002 only numbered between 10 and 25 individuals.
Animal pictures of the day: booming captive breeding for Mauritius skinks
(08/14/2012) Three female orange-tailed skinks skinks have produced 16 skink babies in just four months, according to the Durrell Wildlife Conservation Trust (DWCT), which is captive breeding the Critically Endangered species. The breeding efforts are all the more remarkable since the females only produce two eggs at a time.

(05/21/2012) A new lizard has been discovered in a war-torn area of the Democratic Republic of the Congo (DRC). According to a paper in the African Journal of Herpetology<, the new species was found hiding under a rock in the high grasslands of the Marungu Plateau, an area known for landmines.
Skink biodiversity jumps 650 percent in the Caribbean
(04/30/2012) In a single paper in Zootaxa scientists have rewritten the current understanding of lizard biodiversity in the Caribbean. By going over museum specimens of skinks, scientists have discovered 24 new species and re-established nine species previously described species, long-thought invalid. The single paper has increased the number of skinks in the Caribbean by 650 percent, from six recognized species to 39. Unfortunately, half of these new species may already be extinct and all of them are likely imperiled.
New reptile discovered in world's strangest archipelago
(04/25/2012) Few people have ever heard of the Socotra Archipelago even though, biologically-speaking, it is among the world's most wondrous set of islands. Over one third of Socotra's plants are found no-where else on Earth, i.e. endemic, while 90 percent of its reptiles are also endemic. Adding to its list of unique life-forms, researchers have recently uncovered a new skink species that is found only on the island of Abd al Kuri, which is slightly smaller than New York City's Staten Island. Dubbed the "the other Galapagos," the four Socotra islands are under the jurisdiction of Yemen, although geographically speaking the islands are actually closer to Somalia.

(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.
Photo: new blue, red, yellow lizard discovered in the Andes
(02/13/2012) Researchers have discovered a new species of lizard in the Peruvian Andes, whose males sport beautiful colors, according to a paper in ZooKeys. The highest-dwelling known species of the genus Potamites, the new lizard, dubbed Potamites montanicola, was found in forest streams at 1,500 to 2,000 meters (4,900 to 6,500 feet). The species was discovered as apart of a biodiversity monitoring program by COGA, a Peruvian fossil fuel company.

The dark side of new species discovery
(12/21/2011) Scientists and the public usually rejoice when a new species is discovered. But biologist Bryan Stuart has learned the hard way that the discovery of new species, especially when that species is commercially valuable, has a dark side-one that could potentially wipe out the new species before protections can be put in place. Stuart has discovered 27 species unknown previously to scientists - so far. That includes 22 species of frogs, three types of snakes, and two salamanders. His experience with one of these, a warty salamander from Laos with striking markings (Laotriton laoensis), opened his eyes to a dark side of scientific discovery: commercial overexploitation before protections are in place. Shortly after Stuart described the previously unknown species Paramesotriton laoensis in a scientific paper published in 2002, commercial dealers began collecting this Lao newt for sale into the pet trade. In essence, the dealers used Stuart's geographic description in the paper as a “roadmap” to find the rare newt.
Photos: 40% of Madagascar's reptiles at risk of extinction
(11/10/2011) 40 percent of Madagascar's terrestrial reptiles are threatened with extinction due to habitat loss and over-collection for the pet trade, reports the International Union for Conservation of Nature (IUCN) in its latest update of the Red List of Threatened Species.
Animal picture of the day: the world's most blue lizard?
(07/20/2011) The blue anole is one of the world's most spectacular reptiles. Found only on the island of Gorgona, the blue anole is so elusive and rare that scientists have been unable to give an estimate of its population. However it is considered threatened due to its dependence on its small island habitat.
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'.
Endangered Madagascar wildlife on sale in Thailand
(06/19/2011) Conservation group TRAFFIC uncovered nearly 600 Madagascar reptiles and amphibians on sale in Thai markets, including endangered species and those banned for sale by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The animals, representing 24 reptiles species and 9 amphibians, are being sold for the international pet trade. "We know there is a significant ongoing illegal trade in protected species from Madagascar, mainly destined for Asia, which has been exacerbated by the current political situation in the country leading to weaker enforcement of existing laws and safeguarding of protected areas," says Richard Hughes, WWF’s Representative in Madagascar.
Traditional Chinese medicine trade takes toll on Indonesia's geckos
(06/01/2011) The call of the tokek, or gecko, is one of the most familiar sounds in Indonesia. Next to the smell of clove cigarettes, the calls to prayer, the friendly smiles and the ferocious afternoon rainstorms, it stands as one of the most easily identifiable characteristics of the country.
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.
Photos: the top ten new species discovered in 2010
(05/23/2011) If we had to characterize our understanding of life on Earth as either ignorant or knowledgeable, the former would be most correct. In 250 years of rigorous taxonomic work researchers have cataloged nearly two million species, however scientists estimate the total number of species on Earth is at least five million and perhaps up to a hundred million. This means every year thousands of new species are discovered by researchers, and from these thousands, the International Institute for Species Exploration at Arizona State University selects ten especially notable new species.
No limbs or sight needed: bizarre new lizard uncovered in Cambodia
(05/09/2011) A new species of legless lizard has been discovered in Cambodia. Herpetologist Neang Thy uncovered, literally, the new species when he turned over a log in the species-rich Cardamom Mountains. While the new lizard looks like a snake or a big earthworm, it is in fact a lizard belong to the Dibamidae family. These bizarre reptiles spend much of their lives burrowing underground for insects, which has allowed them to lose the need for limbs.
Over a thousand geckos freed from criminal taxi
(05/08/2011) Over a thousand tokay geckos (Gekko gecko) were found in a single trunk of a taxi by the Wildlife Rapid Response Team (WRRT), forestry officials, and military police in Cambodia. WRRT is wildlife-crimes program run by Wildlife Alliance. Boxes filled the taxi’s trunk. In the boxes were bags stuffed with 1,027 tokay geckos, of which nineteen had perished.

Photos: rats drive island lizard to extinction
(06/29/2010) The Selmunett lizard (Podarcis filfolensis ssp. Kieselbachi) is very likely extinct, according to Maltese naturalist Arnold Sciberras. One of four subspecies of the Maltese wall lizard, the Selmunett lizard was last seen in 2005. Although the lizard's home—Selmunett Island—has long been uninhabited by people, that fact did not help save the lizard. Over-predation by introduced rats is thought to be the primary cause of lizard's extinction.
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.
