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
(10/4/2006) 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'
(8/7/2006) 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
(7/21/2006) 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
(6/27/2006) 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
(5/17/2006) 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
(4/14/2006) 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
(10/5/2005) 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
(7/18/2005) 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.


Ground Reptiles and Amphibians
(3/1/2005) The most abundant vertebrate predators of the forest floor are reptiles, namely snakes and lizards. Best known of forest snakes are the giant constrictors, pythons of the Old World and Australasia, and boas of New World, but many of these are arboreal, aquatic, or relatively small. The majority of the snakes of the forest floor are small to medium sized, nocturnal, and mildly poisonous. They eat a range of amphibians, mammals, small birds, and insects. Very few of these species pose a threat to humans, although some are notorious for inflicting bites. The fer-de-lance viper of the New World, cobras of the Old World, and bushmaster of the New World are well-known examples.


Rainforest Canopy - Amphibians, Reptiles, Invertebrates
(3/1/2005) Frogs are overwhelmingly the most abundant amphibians in the rainforest. Unlike temperate frogs that are mostly limited to habitats near water, tropical frogs are most abundant in the trees, and relatively few are found near bodies of water on the forest floor. The reason for this is quite simple: frogs must always keep their skin moist since almost half of their respiration in carried out through the skin. The high humidity of the rainforest and frequent rainstorms gives tropical frogs infinitely more freedom to move into the trees and escape the many predators of rainforest waters. The differences between temperate and tropical frogs extend beyond their habitat. Whereas nearly all temperate frogs lay their eggs in water, the majority of rainforest species place eggs in vegetation or lay them in the ground. By leaving the water, frogs avoid egg-predators like fish, shrimp, aquatic insects, and insect larvae. Several species of frogs, including the American glass frogs, lay their eggs on vegetation that overhangs water. The humid climate keeps the eggs moist and when the tadpoles hatch they drop into the water below. Glass frogs are also interesting because they are transparent except for their visible organs and the faint yellow spots that some species possess. These yellow spots resemble a cluster of the frog's eggs, enough to fool predators. Other frog species develop fully into froglets within their eggs, and emerge as fully formed frogs, thus by-passing the tadpole stage altogether..
