Researchers Find Motion And Muscles Don't Always Work In Lockstep
2014-03-14 15:44:04

University of California - Riverside Unique research by UC Riverside biologists on wild anole lizards reveals new insights on how animals might adapt to their habitat and handle various forms of motion Animals "do the locomotion" every day, whether it's walking down the hall to get some coffee or darting up a tree to avoid a predator. And until now, scientists believed the inner workings of movement were pretty much the same — the nerves send a message to the muscles and there is...

Evolution Is Predictable Shown by Lizards
2013-07-19 10:21:14

University of California - Davis If you could hit the reset button on evolution and start over, would essentially the same species appear? Yes, according to a study of Caribbean lizards by researchers at the University of California, Davis, Harvard University and the University of Massachusetts. The work is published July 19 in the journal Science. The predictability of evolution over timescales of millions of years has long been debated by biologists, said Luke Mahler, a postdoctoral...

One Lizard Species Adapts Quickly To Climate Change
2012-11-27 12:04:38

April Flowers for redOrbit.com - Your Universe Online A new study from Duke University shows that one tropical lizard's tolerance for cold is a bit stiffer than scientists had assumed. The Puerto Rican lizard Anolis cristatellus has adapted to the colder winters of Miami, Florida, the study shows. This lizard may also be able to tolerate temperature variations caused by climate change. The results of this study will be published in the December 6 issue of The American Naturalist....

Lizard Study Analyzes Importance Of The Founder Effect
2012-02-03 05:54:43

A team of American researchers have reportedly completed what they are calling the first experimental study of the phenomenon known as the founder effect -- the loss of genetic variation that occurs when a new population is established created using a small group from a larger existing population -- in a natural setting. The researchers, whose work was published online Friday in Science Express and is scheduled to appear in the print journal Science on February 17, "had an unprecedented...

Researchers Produce First Genome Sequence Of Lizard
2011-08-31 12:43:03

  Researchers have produced the first genome sequence of a lizard. The green anole lizard is the first non-bird species of reptile to have its genome sequenced and assembled. Researchers have assembled and analyzed over 20 mammalian genomes, but the genetic landscape of reptiles remains relatively unexplored. "Sometimes you need to be at a certain distance in order to learn about how the human genome evolved," Jessica Alföldi, co-first author of the paper and a...

Anoles show they can solve novel problem, remember solutions Tropical lizards may be slow. But they aren't dumb. They can do problem-solving tasks just as well as birds and mammals, a new study shows. A Duke University experiment tested Puerto Rican anoles on several cognitive tasks and found they can learn and remember to solve a problem they've never faced before. The results challenge the scientific stereotype that reptiles have limited cognitive abilities and methods for finding food. The...

It's long been accepted by biologists that environmental factors cause the diversity"”or number"”of species to increase before eventually leveling off. Some recent work, however, has suggested that species diversity continues instead of entering into a state of equilibrium. But new research on lizards in the Caribbean not only supports the original theory that finite space, limited food supplies, and competition for resources all work together to achieve equilibrium; it builds on...

Millions of years before humans began battling it out over beachfront property, a similar phenomenon was unfolding in a diverse group of island lizards. Often mistaken for chameleons or geckos, Anolis lizards fight fiercely for resources, responding to rivals by doing push-ups and puffing out their throat pouches. But anoles also compete in ways that shape their bodies over evolutionary time, says a new study in the journal Evolution. Anolis lizards colonized the Caribbean from South America...

From geckos and iguanas to Gila monsters and Komodo dragons, lizards are among the most common reptiles on Earth. They are found on every continent except Antarctica. One even pitches car insurance in TV ads. They seemingly can adapt to a variety of conditions, but are most abundant in the tropics. However, new research that builds on data collected more than three decades ago demonstrates that lizards living in tropical forests in Central and South America and the Caribbean could be in...

If you've ever tried capturing a lizard, you'll know how difficult it is. But if you do manage to corner one, many have the ultimate emergency quick release system for escape. They simply drop their tails, leaving the twitching body part to distract the predator as they scamper to safety. According to Gary Gillis from Mount Holyoke College, USA, up to 50% of some lizard populations seem to have traded some part of their tails in exchange for escape. This made Gillis wonder how this loss may...

The Knight Anole, Anolis equestris, is a species of lizard in the family Polychrotidae. It is native to Cuba, but has been introduced into the Dade and Broward counties of Florida. Although these lizards are diurnal, after sunning themselves on asphalt, rocks, or sidewalks, they can hunt into the night on occasion. Their diet consists of prey like tarantulas and other anoles. The Knight Anole is the largest of all anoles and grows to a length of 13 to 20 inches including the tail. It is...

The Brown Anole ( Norops sagrei) is a lizard of the anole family that is native to Cuba and the Bahamas. It has been widely introduced and is now common in southern Florida, other Caribbean islands, and elsewhere in the region. Its introduction in the USA has damaged stocks of the native Carolina Anole. The Brown Anole is a slender lizard reaching about 18cm in length. Males and females differ somewhat in coloration: males have a dark stripe down their backs, females a light stripe. As in...

The Carolina Anole (Anolis carolinensis), also known as the Green Anole, is an aboreal lizard found primarily in the southeastern parts of the United States and some Caribbean islands. It was described by Voigt in 1832 and Carolus Linnaeus in 1758 (as Lacerta principalis, fide Duméril and Bibron 1837: 121). Common synomyns include the American Anole and Red-throated Anole. It is sometimes referred to as the American chameleon due to its color-changing abilities, although it is not a...
