Serious disease in pet lizards caused by new bacteria
Skin infections are common in pet lizards and can lead to fatal organ disease and septicaemia. The cause of these diseases has been unclear but now researchers in Belgium have discovered a new bacterium responsible for dermatitis in desert lizards. According to research published in the September issue of the International Journal of Systematic and Evolutionary Microbiology, the discovery could help control the disease and protect endangered species. (2008-09-18)

First supper is a life changer for lizards
For young lizards born into this unpredictable world, their very first meal can be a major life changer. So say researchers who report evidence on July 3 in Current Biology, a Cell Press publication, that this early detail influences how the lizards disperse from their birthplaces, how they grow, and whether they survive. A quick or slow meal even influences the lizards' reproductive success two years later in a surprising way. (2013-07-03)

The mystery of lime-green lizard blood
Green blood is one of the most unusual characteristics in the animal kingdom, but it's the hallmark of a group of lizards in New Guinea. The muscles, bones and tongues of these lizards appear bright, lime-green due to high levels of biliverdin, or a green bile pigment, which is toxic and causes jaundice. Surprisingly, these lizards remain healthy with levels of green bile that are 40 times higher than the lethal concentration in humans. (2018-05-16)

Lizard fossil provides missing link in debate over snake origins
The recent discovery by researchers from the University of Toronto Mississauga and the Museum für Naturkunde Berlin, Germany of a tiny, 47 million-year-old fossil of a lizard called Cryptolacerta hassiaca provides the first anatomical evidence that the body shapes of snakes and limbless lizards evolved independently. (2011-05-18)

Lizard activity levels can help scientists predict environmental change
As average global temperatures rise, animals dependent on external sources to raise their body temperature may spend more time in the shade and less time eating and reproducing. Now, a study of the crested anole shows that lizards are active over a broader range of temperatures than scientists previously thought -- but when temperatures are either too hot or too cold, critical activity levels slow, limiting the abilities of species to cope with climate variability. (2015-03-31)

Lizards can stomach island living
Life on an island isn't always easy. To make the most of the little there is to eat on many Greek islands, the digestive system of Balkan green lizards has evolved considerably compared to family members on the mainland. Many of these insect-eating lizards have special valves to digest plants. These are some of the findings from a study led by Konstantinos Sagonas, published in Springer's journal The Science of Nature. (2015-08-31)

Global warming lethal to baby lizards: Nests become heat traps
The expected impact of climate change on North American lizards is much worse than first thought. A team of biologists led by Arizona State University investigators has discovered that lizard embryos die when subjected to a temperature of 110 degrees Fahrenheit even for a few minutes. They also discovered a bias in previous studies, which ignored early life stages such as embryos. Embryonic lizards are immobile and cannot cool off when surrounding soil becomes hot. (2015-08-18)

Brainy lizards pass test for birds
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. (2011-07-12)

URI scientist: Long-legged lizards better adapted for hurricane survival
Jason Kolbe has been thinking about hurricanes and lizards for many years. The University of Rhode Island professor of biological sciences has measured the length of lizard legs and the size of their toe pads to assess how those factors influence the animal's ability to cling to vegetation during strong storms. He even used a powerful leaf blower to test his hypotheses in a laboratory. (2018-08-17)

Mapping lizard venom makes it possible to develop new drugs
Lizards and other reptiles are not normally considered venomous, but a number of lizard species actually do produce and use venom. The most classic venomous lizard is no doubt the gila monster -- a heavy-bodied lizard. As the first in the world, a group of researchers at Aarhus University has made a comprehensive description of the proteins in the venom which can prove to be relevant in connection with developing new types of drugs. (2015-02-24)

Falling lizards use tail for mid-air twist, inspiring lizard-like 'RightingBot'
Lizards, just like cats, have a knack for turning right side up and landing on their feet when they fall. But how do they do it? Unlike cats, which twist and bend their torsos to turn upright, lizards swing their large tails one way to rotate their body the other, according to work that will be presented at the Society for Experimental Biology meeting on June 29. A lizard-inspired robot, called (2012-06-29)

Research shows that environmental factors limit species diversity
New research on lizards in the Caribbean demonstrates that species diversification is limited by the environment. The finding supports and extends the MacArthur-Wilson theory of island biogeography. (2010-12-20)

Double take: New study analyzes global, multiple-tailed lizards
Curtin research into abnormal regeneration events in lizards has led to the first published scientific review on the prevalence of lizards that have re-generated not just one, but two, or even up to six, tails. (2020-07-06)

Researchers use entire islands in the Bahamas to test survival of the fittest
By using entire islands as experimental laboratories, two Dartmouth biologists have performed one of the largest manipulations of natural selection ever conducted in a wild animal population. Their results, published online on May 9 by the journal Nature, show that competition among lizards is more important than predation by birds and snakes when it comes to survival of the fittest lizard. (2010-05-10)

Lizards pull a wheelie
Lizards that run on two legs haven't evolved to pull the stunt; they're simply pulling a wheelie. Christofer Clemente from the University of Cambridge and colleagues from the University of Western Australia have found that lizards shift their center of mass back as they accelerate forward so that they're forelimbs lift off the ground leaving them running on two legs. (2008-06-13)

Global warming kills gut bacteria in lizards
Climate change could threaten reptiles by reducing the number of bacteria living in their guts, new research suggests. (2017-05-08)

Scaly gem discovered in South American cloudforests
Ecuadorian scientists have discovered a gem-looking new species of shade lizard in cloudforests of northwestern Ecuador. DNA data suggest that the closest relative of the new species is a widespread species living along the Pacific lowlands in Ecuador and Colombia. The study was published in the open-access journal ZooKeys. (2014-05-21)

BYU lizard researcher dusts off 30-year-old field notes for worldwide climate change study
When Brigham Young University biology professor Jack Sites spent summers in the late 1970s collecting lizards in Mexico, he had no idea his field notes would one day help form the foundation for a worldwide study that attributes local lizard extinctions to climate change. Sites is a coauthor on the paper published in this week's issue of Science that reports a global pattern of lizard die-offs in habitats unchanged except for rising temperatures. (2010-05-13)

Rapid changes in climate don't slow some lizards
One tropical lizard's tolerance to cold is stiffer than scientists had suspected. A new study shows that the Puerto Rican lizard Anolis cristatellus has adapted to the cooler winters of Miami. The results also suggest that this lizard may be able to tolerate temperature variations caused by climate change. (2012-11-26)

Castaway lizards provide insight into elusive evolutionary process
A biologist who released lizards on tiny uninhabited islands in the Bahamas has shed light on the interaction between evolutionary processes that are seldom observed. He found that the lizards' genetic and morphological traits were determined by both natural selection and a phenomenon called founder effects, which occur when species colonize new territory. (2012-02-02)

Native lizards evolve to escape attacks by fire ants
Native fence lizards in the southeastern United States are adapting to potentially fatal invasive fire-ant attacks by developing behaviors that enable them to escape from the ants, as well as by developing longer hind legs, which can increase the effectiveness of this behavior. This finding provides biologists with an example of evolution in action, and provides wildlife managers with knowledge that they can use to develop plans for managing invasive species. (2009-01-20)

Lizards may be overwhelmed by fire ants and social stress combined
Lizards living in fire-ant-invaded areas are stressed. However, a team of biologists found that the lizards did not exhibit this stress as expected after extended fire ant exposure in socially stressful environments, leading to questions about stress overload. (2017-05-23)

Island lizards are expert sunbathers, and researchers find it's slowing their evolution
If you've ever spent some time in the Caribbean, you might have noticed that humans are not the only organisms soaking up the sun. Anoles -- diminutive little tree lizards -- spend much of their day shuttling in and out of shade. But, according to a new study in Evolution led by assistant professor Martha Muñoz at Virginia Tech and Jhan Salazar at Universidad Icesi, this behavioral 'thermoregulation' isn't just affecting their body temperature. Surprisingly, it's also slowing their evolution. (2019-04-22)

3 new monitor lizards from the Philippines identified
German scientist Andre Koch from the Zoological Research Museum Alexander Koenig in Bonn together with his supervisor Dr. Wolfgang Boehme and another colleague have described two new monitor lizard species and one new subspecies from the Philippines in a recent article. The species descriptions were published in Zootaza, the world's foremost journal for taxonomic zoology. (2010-05-17)

Lizard venom may contain clues to treating blood clots
Various types of lizard venom are being studied as possible treatments for blood clotting diseases that lead to millions of cases of stroke, heart attack, and deep-vein thrombosis annually. University of Queensland School of Biological Sciences expert Associate Professor Bryan Fry said, while snake venom research has been extensive, lizard venom research was still in its infancy. (2017-08-07)

Biodiversity may limit invasions: Lessons from lizards on Panama Canal islands
Introduced species can become invasive, damaging ecosystems and disrupting economies through explosive population growth. One mechanism underlying population expansion in invasive populations is 'enemy release', whereby the invader experiences relaxation of agonistic interactions with other species, including parasites. (2020-08-09)

Castaway lizards offer new look at evolutionary processes
Biologists who released lizards on tiny uninhabited islands in the Bahamas have uncovered a seldom-observed interaction between evolutionary processes. Jason Kolbe, a biologist at the University of Rhode Island -- along with colleagues at Duke University, Harvard University and the University of California, Davis -- found that the lizards' genetic and morphological traits were determined by both natural selection and a phenomenon called the founder effect. (2012-02-03)

New research: Why bigger animals aren't always faster
New research in the journal Physiological and Biochemical Zoology shows why bigger isn't always better when it comes to sprinting speed. (2012-04-30)

Lizards camouflage themselves by choosing rocks that best match the color of their backs
New research shows wild Aegean wall lizards found on Greek islands choose to sit on rocks that better match their individual colouring. This improves camouflage and so reduces the risk of being attacked by birds when they sit out in the open, raising the intriguing question of how the lizards know what colour they are. (2016-01-25)

Stress hormones help lizards escape from fire ants
When some fence lizards are attacked by fire ants they (2010-08-02)

Lizards change their diet to avoid predators
A scientist from the University of Salamanca and another from Yale University have shown that the presence of predators affects the behavior of Acanthodactylus beershebensis, a lizard species from the Negev Desert in the Near East. According to the study, these reptiles move less and catch less mobile and different prey if they are under pressure from predators. (2009-12-02)

Baby blue-tongues are born smart
Young Australian eastern blue-tongue lizards (Tiliqua scincoides) are every bit as clever as adults, researchers have found. Life is hard for baby blue-tongues. As soon as they are born, they are on their own, with neither parental support nor protection. Adults of the species can grow to 600 millimetres long and enjoy the benefits of thick scales and a powerful bite, but the young are much smaller and thus more vulnerable to predation. (2019-07-15)

Worm lizards dispersed by 'rafting' over oceans, not continental drift
Tiny, burrowing reptiles known as worm lizards became widespread long after the breakup of the continents, leading scientists to conclude that they must have dispersed by rafting across oceans soon after the extinction of the dinosaurs, rather than by continental drift as previously thought. (2015-03-31)

Getting a tail up on conservation?
Dr. Shai Meiri of Tel Aviv University's Department of Zoology has developed an improved tool for translating lizard body lengths to weights. Dr. Meiri's new equations calculate this valuable morphological feature to estimate the weight of a lizard species in a variety of different ecosystems. (2010-09-01)

Robots may need lizard-like tails for 'off-road' travel
Robots may one day tackle obstacles and traverse uneven terrains thanks to collaborative research analyzing the motion of lizards. The study, which featured a University of Queensland researcher, used a slow motion camera to capture the nuanced movement of eight species of Australian agamid lizards that run on two legs -- an action known as 'bipedal' movement. (2018-09-25)

The origin of snakes -- new evolutionary scenario presented
The early evolution of snakes happened from surface-terrestrial to burrowing in the lizard-snake transition suggests a research group at the University of Helsinki. (2018-01-25)

Method assesses health and size of lizard populations
Monitoring programs that survey many wildlife species at the same time across large geographic regions are important for informing conservation decisions, but reptiles are often missing from these efforts because they are difficult to survey. As described in a new Ecology & Evolution study, researchers have now developed a way to provide accurate estimates of lizard populations. (2019-02-21)

Christmas colors disguise gliding lizards in the rainforest
By mimicking the red and green colors of falling leaves, Bornean lizards avoid falling prey to birds whilst gliding, new research has found. (2014-12-23)
