The first non-avian reptile genome has been sequenced, that of the North American green anole lizard (Anolis carolinensis). The anole is an emerging model for the study of adaptive radiation and convergent evolution. The genome includes a previously unknown X chromosome, with no homology to known amniote sex chromosomes, and microchromosomes that share a common ancestry with those in birds, but without their unusual characteristics. The evolution of the amniotic egg was one of the great evolutionary innovations in the history of life, freeing vertebrates from an obligatory connection to water and thus permitting the conquest of terrestrial environments1. Among amniotes, genome sequences are available for mammals and birds2,3,4, but not for non-avian reptiles. Here we report the genome sequence of the North American green anole lizard, Anolis carolinensis. We find that A. carolinensis microchromosomes are highly syntenic with chicken microchromosomes, yet do not exhibit the high GC and low repeat content
The family Varanidae probably originated in Asia at least 65 million years ago,[21] although some estimates are as early as the late Mesozoic (112 million years ago).[22] Monitor lizards probably expanded their geographic range into Africa between 49 and 33 million years ago, possibly via Iran, and to Australia and the Indonesian archipelago between 39 and 26 million years ago.[23]. Varanids last shared a common ancestor with their closest living relatives, earless monitors, during the Late Cretaceous. During the Late Cretaceous Period, monitor lizards or their close relatives are believed to have evolved into amphibious and then fully marine forms, the mosasaurs, some of which reached lengths of 12 m (39 ft) or more. Snakes were believed to be more closely related to monitor lizards than any other type of extant reptile; however, snakes have been more recently proposed to be the sister group of the clade of iguanians and anguimorphs.[18] Like snakes, monitor lizards have forked tongues, which ...
The exposure to environmental toxicants such cadmium (Cd) is an important research area in wildlife protection. In this study, the effect of Cd oral administration on the ovarian structure and function and on reproductive performance of the Italian wall lizard Podarcis sicula was studied. In vivo, adult female lizards were randomly assigned to three groups. Cd was given with food in single dose and in multiple doses 3 days/week for 4 weeks at dose of 1.0 μg/g body weight. Following euthanasia, the ovaries were removed and analyzed for morpho-functional changes. Results demonstrated that Cd increases prefollicular germ cells number; the evaluation of the number of follicles detects significantly higher number of atretic growing follicles, whereas primary follicles remain unchanged with respect to controls. After Cd treatments, follicles are deformed by the presence of large protrusions and a general dysregulation in the follicle organization is observed. The zona pellucida is also affected. Cd ...

Back at the house Daniel welcomed me with a present: A Southern Alligator Lizard, GERRHONOTUS MULTICARINATUS. Id been looking for one of these because its a bit unusual, despite the fact that its abundant and frequently seen here, and it looks a lot like the normal fence lizard, which we also have. In fact, at first I had a hard time distinguishing alligator lizards from fence lizards. It must be a case of convergent evolution because the two species are very unrelated, being in entirely different families and even suborders. You can see the taxonomic relationships among different kinds of lizards on my Lizard Classification Page at www.backyardnature.net/lizclass.htm.There youll observe that alligator lizards are about as unrelated to average lizards (iguanid lizards) such as fence lizards and anoles, as are Gila Monsters. One difference between alligator lizards and regular lizards is that their have bony scales (osteoderms) encasing them so effectively that their bodies are fairly ...

Monitor lizards are medium to large reptiles which can still be found in Africa, the Near East, South Asia, Indonesia and Australia. All modern monitor lizards belong to the genus Varanus. Among them are some of the most fascinating and impressive reptiles of our age, such as the Komodo Dragon (Varanus komodoensis), the largest lizard in the world.. Extinct relatives of the monitor lizards have been documented in Europe since the Eocene (56 to 34 million years ago). In our latitudes they reached their greatest distribution in the Miocene (23 to 5.5 million years ago), before they died out in Europe in the late Pliocene (about 2.5 million years ago) - or at least that was the view up till now.. New discovery near Athens ...
European Wall Lizards were introduced to the Saanich Peninsula of Vancouver Island in 1970, after the private zoo that housed the lizards closed. Since that time Wall Lizards have become firmly established and are spreading. Several separate populations are now present on Vancouver Island due to people collecting the lizards and releasing them at new locations (such as their yards and gardens). To prevent the spread of these lizards it is very important to never, never capture them or move them, even a short distance.. Wall Lizards live in some of the same areas as Northwestern Alligator Lizards. The two lizards have been seen basking on the same rocks and are suspected to hibernate together in at least one location. Little is known about the effects of Wall Lizards on Alligator Lizards but since they share habitat in some locations and eat similar things, there is potential for competition. Monitoring and study of the European Wall Lizard on Vancouver Island will help to determine if this ...
The common side-blotched lizard (Uta stansburiana) is a species of side-blotched lizard found on the Pacific Coast of North America. It is notable for having a unique form of polymorphism wherein each of the three different male morphs utilizes a different strategy in acquiring mates. The three morphs compete against each other following a pattern of rock, paper, scissors, where one morph has advantages over another but is outcompeted by the third. The specific epithet stansburiana is in honor of Captain Howard Stansbury of the US Corps of Topographical Engineers, who collected the first specimens while leading the 1849-1851 expedition to explore and survey the Great Salt Lake of Utah. The systematics and taxonomy of these widespread and variable lizards is much disputed. Countless forms and morphs have been described as subspecies or even distinct species. The forms which occur in most of Mexico (except Baja California) have been recognized as a very distinct species, the eastern side-blotched ...
Australia is not only home to venomous snakes, spiders and jellyfish, now scientists have discovered that its lizards are venomous too.. For instance little bearded dragon lizards that cruise around the suburbs have classic rattlesnake venom, scientists report in the journal Nature.. But the venom is not dangerous to humans, Dr Bryan Fry from the University of Melbournes Australian Venom Research Unit says, who led the international research team.. The lizards do not produce enough venom and what little they do is used to kill prey.. Dr Fry spent months in the Australian desert and tropics capturing, studying and milking dozens of lizards.. He and his colleagues then studied their toxins, DNA and evolution.. The researchers discovered that two common lizard lineages found in Australia, monitor lizards and iguania, have mouth glands that secrete venom toxins.. This was surprising as until now scientists had only found two lizard species around the world that produced venom, the gila monster and ...
Calcium deficiencies are common heath issue in Tokay geckos which may lead to serious health issues like Metabolic Bone Disease or MBD. Like any other reptiles, Tokay geckos need calcium for them to grow and produce healthy eggs. Calcium is an important mineral to a reptiles health but giving them with a bowl of calcium daily doesnt guarantee that they absorb or get the right amount of calcium. It is important to note however, that calcium absorption is a process that involves other processes to be able to efficiently deliver calcium in the system. Other than giving your Tokay geckos a daily dose of calcium it is also important that your Tokay geckos have enough Vitamin D3 in their system. Vitamin D3 is naturally produced in a reptiles body when exposed to UVB (ultraviolet light B) which can be done using UVB lighting or exposing your Tokay geckos to natural sunlight. UVB rays trigger the kidneys of reptiles to create vitamin D3 which is delivered into their bloodstream and enable the cells ...

Several lizard species have been shown to exhibit kin recognition, including green iguanas (Iguana iguana), three Australian Scincid species (Egernia stokesii, E. striolata and Tiliqua rugosa) and common lizards (Lacerta vivipara). Thus, observations of close neighboured individuals of the common lizard that consist of differently or same-aged individuals at a given site may generate speculation about the relatedness structure of such combinations and putative

The Australian central bearded dragon (Pogona vitticeps) is being developed as a reptilian model for such comparisons, with whole-genome sequencing near completion. The karyotype consists of 6 pairs of macrochromosomes and 10 pairs microchromosomes (2n=32), including a female heterogametic ZW sex microchromosome pair. Here, we present a molecular cytogenetic map for P. vitticeps comprising 87 anchor bacterial artificial chromosome clones that together span each macro- and microchromosome. It is the first comprehensive cytogenetic map for any nonavian reptile. We identified an active nucleolus organizer region (NOR) on the sub-telomeric region of 2q by ...
To those not familiar with them, glass lizards in the genus Ophiosaurus (literally, snake [ophio-] -lizard [saurus]) look rather like a snake with ears and blinking eyes. Careful inspection of the vent area in some species will show tiny spurs, similar to a boa or python. Related to the alligator lizards (Gerrhonotus), their head and body shape are reminiscent of those species, including the conical teeth and lateral fold. They are very un-snakelike when held, being firm in the body like an alligator lizard or large skink, rather than the softly supple body associated with snakes.. Legless lizards are found in the Old and New Worlds, ranging in areas of Indonesia, southern Asia, the Near East, southeastern Europe, North Africa, and North America. The European and American legless lizards are in the family Anguidae, Anniellidae, and Xenosauridae; the Australasian ones in the family Pygopodidae. Some of the Anguidae legless lizards are called lateral fold lizards due to the pronounced lateral fold ...
Mark-recapture techniques were used to investigate population size, age distribution, size distribution and sex ratio in a population of the lacertid lizard Podarcis bocagei in an abandoned gravel pit in northwest Spain. The study was carried out over a 2-year period. Despite relatively high maximum longevity, the population age distribution was characteristic of small, short-lived lizard species (i.e., there was a relatively high proportion of immature individuals). Population size declined over the study period, largely because of a drop in the number of immature animals: this may be partially attributable to density-dependent factors, but was probably due largely to a decline in habitat favourability as a result of colonisation of the study site by vegetation. The sex ratio was significantly female-biased in all cohorts studied, not only among adults but also among juveniles and sub-adults. However, sex ratio at hatching (as investigated by laboratory hatching of clutches laid by captured pregnant

Australia has many different varieties of monitor lizards (in Australia monitor lizards are referred to as goannas). There are many different varieties, pygmy varieties grow no larger than a human hand right up to the large Perentie monitor that can grow up to a length of over 2.5 m.. Weve not heard of anyone keeping goannas as pets in Australia, and at this stage have little we can report about them. Overseas, water and Nile monitors are kept as pets. Some people keep them in large enclosures, others let them roam their houses though having watched some videos on Youtube today, I would not be doing this personally if you had other pets, or young children!.

It has been speculated that the oral flora of the Komodo dragon (Varanus komodoensis) exerts a lethal effect on its prey; yet, scant information about their specific oral flora bacteriology, especially anaerobes, exists. Consequently, the aerobic and anaerobic oral bacteriology of 16 captive Komodo dragons (10 adults and six neonates), aged 2-17 yr for adults and 7-10 days for neonates, from three U.S. zoos were studied. Saliva and gingival samples were collected by zoo personnel, inoculated into anaerobic transport media, and delivered by courier to a reference laboratory. Samples were cultured for aerobes and anaerobes. Strains were identified by standard methods and 16S rRNA gene sequencing when required. The oral flora consisted of 39 aerobic and 21 anaerobic species, with some variation by zoo. Adult dragons grew 128 isolates, including 37 aerobic gram-negative rods (one to eight per specimen), especially Enterobacteriaceae; 50 aerobic gram-positive bacteria (two to nine per specimen), ...

This is the incredible moment a giant monitor lizard joined tourists on the beach - before calmly going for a swim. The 5ft-long reptile stunned beachgoers when it emerged from woodland and walked onto the sand on the island of Ko Hong in Krabi, southern Thailand, on Tuesday (April 13). Footage shows how the Godzilla-like creature ignored the visitors and calmly entered the clear blue sea. It then glided past swimmers who looked on in amazement. With its head beneath the water, the reptile seems just like any other tourist enjoying snorkeling while looking at fish in the turquoise waters. Tourist Nam Sudarat, who recorded the video while on a day trip to the idyllic island, said: The monitor lizard was so relaxed. He just ignored all the humans on the beach and went swimming. I didnt see him come back because we left. The monitor swam to a nearby rock island seen in the distance where it climbed onto the surface and basked in the hot sun, with temperatures approaching 40 degrees Celsisus. Local

Chromatophoromas are tumours of pigment-producing cells of the skin and are rarely reported in reptiles. These tumours are subclassified on the basis of the type of pigment. The present study characterizes chromatophoromas arising in 26 reptiles, including six snakes, 19 lizards and a tortoise. These include the first reports of melanophoromas in a yellow anaconda (Eunectes notaeus), pigmy rattlesnake (Sistrurus spp.), southern water snake (Nerodia fasciata), veiled chameleon (Chamaeleo calyptratus) and leopard gecko (Eublepharis macularius); the first reports of benign iridophoromas in a savannah monitor (Varanus exanthematicus), veiled chameleon and bearded dragon (Pogona vitticeps); and the first description of a malignant iridophoroma in a bearded dragon. Additionally, in three bearded dragons a mucinous type of melanophoroma is described for the first time. Chromatophoromas generally arose from the skin of the body and head and ranged in size from 0.2 to 2.0cm in diameter. In six cases ...

The wall lizard is very agile and, unlike British lizards which spend their time on the ground, can often be seen running up verticle surfaces like rock faces and - of course - walls. Releasing non-native reptile species into the wild is illegal, and some evidence suggests native lizard numbers have fallen in areas where wall lizards have become established.. To better undestand the animals and their impact on local wildlife, scientists are asking members of the public to help them track the reptiles.. Robert Williams, running the study, said, They are very easy to spot basking on sunny days. Considerable survey effort is required to get around to all the known wall lizard sites and there is a need for updated population surveys, assessment of range expansion, and of course identification of new populations. This is where we need your help! You can help us assess just how widespread the lizards are in the UK and make a valuable contribution to this project by reporting your own wall lizard ...
According to the results, M. viride was identified as cause of granulomatous glossitis, pharyngitis, and disseminated visceral mycosis in three different lizard species. Besides a disease outbreak in a collection of carpet chameleons in 1964, these are the first documented cases in veiled chameleons, panther chameleons, and inland bearded dragons (21). Pathomorphological findings are comparable to mycoses caused by M. granulomatis (19, 20). Observations of disease outbreaks caused by M. granulomatis in collections of veiled chameleons within a time frame of 10 months are suggestive of a primary fungal pathogen (19, 20). This is most likely also the case with M. viride infections in lizard species, which are described here. In one collection of inland bearded dragons, two individuals revealed visceral mycosis, and one more was infected by M. viride within a time frame of 1 month. This was also the case for another collection of inland bearded dragons, in which one lizard died due to disseminated ...

Hurricane Maria devastated Caribbean islands. On Dominica, two anole lizard species adapted grips ten times stronger to survive the increased environmental pressures. Scientists are unsure if the lizards adaptions resulted from natural selection, but if it was, hurricanes may have driven the most rapid rate of evolutionary change ever recorded.
Wall lizards of the genus Podarcis (Sauria, Lacertidae) comprise 17 currently recognized species in southern Europe, where they are the predominant nonavian reptile group. The taxonomy of Podarcis is complex and unstable. Based on DNA sequence data, the species of Podarcis falls into four main groups that have substantial geographic coherence (Western island group, southwestern group, Italian group, and Balkan Peninsula group). The Balkan Peninsula species are divided into two subgroups: the subgroup of P.taurica (P. taurica, P. milensis, P. gaigeae, and perhaps P. melisellensis), and the subgroup of P. erhardii (P. erhardii and P. pelo- ponnesiaca). In the present study, the question of phylogenetic relationships among the species of Podarcis encountered in the Balkan Peninsula was addressed using partial mtDNA sequences for cytochrome b (cyt b) and 16S rRNA (16S). The data support the mono- phyly of Podarcis and suggest that there are three phylogenetic clades: the clade A (P. taurica, P. ...
The diet of some horned lizards consists of specific insects, while other species are more catholic in their tastes. Not only does P. solare prefer ants, it has a strong preference for harvester ants, which may make up to 90 percent of its diet. As diets go, ants are low return items because so much of their body consists of indigestible chitin. Thus, the regal horned lizard must eat a great number of ants to meet its nutritional needs. This diet requires space, which is why the stomach of the regal horned lizard may represent up to 13 percent of its body mass. Ant-eating horned lizards usually capture their prey with their sticky tongues rather than grabbing it with their jaws. In addition, they have modified skeletal morphologies, such as shorter teeth and reduced diameter of the bones of the lower mandible.. Horned lizards are no exception to the general rule that lizards are not attracted to dead insects as food the ants must be alive and moving for the lizard to show interest in them as ...
The worlds largest lizard, Komodo dragons live on five small islands in Indonesia. The saliva of these creatures contains at least 57 species of bacteria, which are believed to contribute to the demise of their prey. Yet, the Komodo dragon appears resistant to these bacteria, and serum from these animals has been shown to have antibacterial activity. Substances known as cationic antimicrobial peptides (CAMPs) are produced by nearly all living creatures and are an essential part of the innate immune system. So, Barney Bishop, Monique van Hoek and colleagues at the College of Science at George Mason University wondered whether they could isolate CAMPs from Komodo dragon blood, as they previously had done with alligator blood to expand the library of known CAMPs for therapeutic studies ...
Numerous species of lizard are kept as pets, including bearded dragons,[67] iguanas, anoles,[68] and geckos (such as the popular leopard gecko).[67] Lizards appear in myths and folktales around the world. In Australian Aboriginal mythology, Tarrotarro, the lizard god, split the human race into male and female, and gave people the ability to express themselves in art. A lizard king named Moo features in Hawaii and other cultures in Polynesia. In the Amazon, the lizard is the king of beasts, while among the Bantu of Africa, the god Unkulunkulu sent a chameleon to tell humans they would live forever, but the chameleon was held up, and another lizard brought a different message, that the time of humanity was limited.[69] A popular legend in Maharashtra tells the tale of how a common Indian monitor, with ropes attached, was used to scale the walls of the fort in the Battle of Sinhagad.[70] In the Bhojpuri speaking region of India and Nepal, there is a belief among children that, on touching Skunks ...
Somatic growth patterns represent a major component of organismal fitness and may vary among sexes and populations due to genetic and environmental processes leading to profound differences in life-history and demography. This study considered the ontogenic, sex-specific and spatial dynamics of somatic growth patterns in ten populations of the worlds largest lizard the Komodo dragon (Varanus komodoensis). The growth of 400 individual Komodo dragons was measured in a capture-mark-recapture study at ten sites on four islands in eastern Indonesia, from 2002 to 2010. Generalized Additive Mixed Models (GAMMs) and information-theoretic methods were used to examine how growth rates varied with size, age and sex, and across and within islands in relation to site-specific prey availability, lizard population density and inbreeding coefficients. Growth trajectories differed significantly with size and between sexes, indicating different energy allocation tactics and overall costs associated with reproduction.
Why bother running on hind legs when the four youve been given work perfectly well? This is the question that puzzles Christofer Clemente. For birds and primates, theres a perfectly good answer: birds have converted their forelimbs into wings, and primates have better things to do with their hands. But why have some lizards gone bipedal? Have they evolved to trot on two feet, or is their upright posture simply a fluke of physics? Curious to find the answer, Clemente and his colleagues Philip Withers, Graham Thompson and David Lloyd decided to test how dragon lizards run on two legs (p. 2058).. But first Clemente had to catch his lizards. Fortunately Thompson was a lizard-tracking master. Driving all over the Australian outback, Clemente and Thompson eventually collected 16 dragon lizard species, ranging from frilled neck lizards to the incredibly rare C. rubens, found only on one remote Western Australian cattle station. Returning to the Perth lab, Clemente and Withers set the lizards running ...
After decades of surveying Sceloporus lizard populations in Mexico, an international research team has found that rising temperatures have driven 12 percent of the countrys lizard populations to extinction. An extinction model based on this discovery also forecasts a grim future for these ecologically important critters, predicting that a full 20 percent of all lizard species could be extinct by the year 2080.
Naïve large Australian varanid lizards have recently been shown to suffer a massive increase in mortality (| 95%) when attempting to feed on this toxic amphibian. The high susceptibility of Australian varanids to toad toxin is caused by minor mutations in the sodium-potassium-ATPase enzyme. In the present study we show that Komodo dragons (Varanus komodoensis)…
Collared lizards are capable of running swiftly on their hind legs, the body held off the ground at a 45 angle, with tail and forelimbs raised. The stride is up to 3 times the length of the body. They do not lose their tails easily, as they are useful in maintaining balance as the lizards sprint on hind legs. Speed facilitates the capture of prey by these visually oriented lizards. They have large heads with strong jaw muscles that allow them to get a powerful grip on large prey such as lizards. Though fairly bold, if confronted by a predator, collared lizards quickly dive into rock crevices to avoid being eaten.. These lizards often sit on large rocks basking in the sun and looking out for other individuals or food. Males are highly territorial and have stereotypical head-bobbing and push-up displays. Collared lizards primarily eat grasshoppers, but also eat other insects as well as lizards, including their own species. In early summer females lay 1 to 13 eggs; they are capable of reproducing ...
Children got an unconventional geography lesson Thursday from a lizard and reptile expert who brought a world of living dragons to the Lovell Room of the Stratford Library. Brian Kleinman of Riverside Reptiles of Connecticut in Hartford introduced 60 children and 33 adults to about a dozen lizards, one legless lizard and a snake, sharing with the audience some information about each creature, including their native habitats and what they like to eat. The tiger salamander, for instance, is native to the United States, while the leopard gecko is found in the harsh environments of western India and the Middle East, where there are extremes of cold and heat, he said. [...] no, it doesnt talk or sell insurance, Kleinman said of the gecko, familiar to many as the animated spokesreptile on TV ads for Geico Insurance. Children enjoyed watching a bearded dragon eat its favorite food: a live baby cockroach, and a 5-foot-long, 20-pound Argus monitor lizard, a relative of the giant Komodo dragon, snack
To estimate the basic reproduction number (R(0)) of Borrelia lusitaniae and Borrelia afzelii, we formulated a mathematical model considering the interactions among the tick vector, vertebrate hosts, and pathogens in a 500-ha enclosed natural reserve on Le Cerbaie hills, Tuscany, central Italy. In the study area, Ixodes ricinus were abundant and were found infected by B. lusitaniae and B. afzelii. Lizards (Podarcis spp.) and mice (Apodemus spp.), respectively, are the reservoir hosts of these two Borrelia burgdorferi sensu lato (s.l.) genospecies and compete for immature ticks. B. lusitaniae R(0) estimation is in agreement with field observations, indicating the maintenance and diffusion of this genospecies in the study area, where lizards are abundant and highly infested by I. ricinus immature stages. In fact, B. lusitaniae shows a focal distribution in areas where the tick vector and the vertebrate reservoir coexist. Mouse population dynamics and their relatively low suitability as hosts for nymphs
Angiostrongylus cantonensis is one of the causative agents of eosinophilic meningitis. Humans get infected when they ingest raw or partially cooked snails or monitor lizards (Varanus bengalensis). There is a popular belief that the tongue and the liver of the monitor lizard has aphrodisiac properties. A 20-year-old man was admitted to our hospital with a history of fever, headache and vomiting. His cerebrospinal fluid revealed eosinophilia. He gave a history of the ingestion of a monitor lizard, ten days prior to the onset of the symptoms. So, a diagnosis of eosinophilic meningitis due to Angiostrongylus cantonensis was made. He was treated with oral albendazole and prednisolone. His symptoms improved gradually within two weeks from his admission.. ...

Lizard Capture and Maintenance:. Thirty two female prairie lizards (Sceloporus undulatus) were caught on Bureau of Land Management reserves near Albuquerque, NM during the last two weeks of July, 2007 and maintained in a room at the biology department of the University of New Mexico under the approval of the UNM-IACUC (#07UNM007). Two lizards were housed per 20 gallon glass terrarium and were provided a sand substrate, as well as perch and shelter spaces built by stacked pieces of plywood and rock. Lizards were kept on a 12 hour (light:dark) photoperiod and a temperature gradient was provided by a 100 watt heat lamp placed at one end of the terrarium and focused on the wood perch, which provided a stable heat gradient that ranged from 39 ± 1.7ºC at the perch to 26 ± 0.8ºC at the cool end of the tank. Resulting mean daytime body temperatures were 36.3 ± 6.2ºC (n = 18). An ultraviolet-B fluorescent light (ZooMed® UVB 10.0 fluorescent) was also provided for vitamin D synthesis. Experimental ...

I didnt know where I could go and be okay. I walked, not caring which way I went, watching the lines of my swimsuit blur into the grass until I saw that I had come down the path where the brambles used to be.. I stopped and held a tear between my eyelashes. It was like peering through a tiny prism. For a second I was back in the tunnel of green light, the way it used to be before Bob Ellis cut away the brambles. I squeezed out the tear and saw the snake, right there at the edge of the path..

Bearded dragons may occasionally be afflicted with a condition called avascular necrosis. In avascular necrosis, one or more blood vessels supplying an area of the body becomes obstructed, leading to death of the organ or tissue that this blood vessel supplies. This problem is more common in iguanas than in bearded dragons, but can be seen in juvenile bearded dragons housed in conditions of low humidity. Low humidity can lead to dysecdysis (difficulty or abnormal shedding of the skin). The tips of the toes and end of the tail are most commonly affected. Successive layers of retained skin can form constricting rings around the toes and tail resulting in restriction of the blood supply to the affected area; eventually the constriction results in avascular necrosis or death of the tissue beyond the point of the constriction. Within a short period of time, the toe or tip of the tail becomes discolored (dark), often becomes infected, and then dies, dries out, and hardens. Necrosis or infection can ...
Systemic blood pressure of Python molurus is similar to mammals and considerably higher than in most other reptiles with the exception of varanid lizards (e.g. Johansen and Burggren, 1980; Burggren and Johansen, 1982; Shelton, 1993; Hicks, 1998; Burggren et al., 1998). Pulmonary arterial pressure is, on the other hand, lower than in any other reptiles, including varanid lizards. Recordings of intraventricular pressure established that the pressure differences are generated within the heart and the contraction of the CA seemed to precede CP, although ejection of blood into the pulmonary circulation occurred before the systemic valves opened (Fig. 3). The substantial pressure separation persisted in the face of large changes in systemic blood pressure induced by sodium nitroprusside or phenylephrine (Fig. 2). Collectively, these observations suggest that the CP and the CA are completely divided during the entire duration of systole so that the cardiac physiology of Python molurus strongly ...

An invasive species of lizard has been spotted in South Carolina as close as Berkeley County, and environmental experts fear the reptiles could pose a threat to local habitats.. The black and white tegu lizard is native to Argentina, but has been transported broadly through wildlife trade to those seeking to keep it as pets. Wild tegus have been a problem in Florida for decades, and recently have moved up to Georgia and now South Carolina.. The South Carolina Department of Natural Resources is monitoring sightings of the species to ensure the population does not get out of control here, and local groups are extending aid.. This is a problem that is going to be hard to control, said Riley Egger, a Coastal Conservation League project manager. Its good that we are getting out fast on this issue because these reptiles populate extremely quickly. We dont want to see impacts on our turtle, turkey and quail populations as a result of these lizards.. As of Sept. 10, eight total sightings of the ...

Based on broad, nearly rangewide sampling, we reanalysed the phylogeography of the Lacerta viridis complex using the mitochondrial cytochrome b gene and the intron 7 of the nuclear b-fibrinogen gene. Using the mitochondrial marker, we identified in phylogenetic analyses 10 terminal clades clustering in four deeply divergent main lineages whose relationships are weakly resolved. These lineages correspond to Lacerta bilineata, L. viridis, the previously identified Adriatic or West Balkan lineage and a newly discovered fourth lineage from the Anatolian Black Sea coast and the south-eastern Balkan Peninsula. Except for the latter lineage, there is considerable phylogeographic structuring in each lineage, with higher diversity in the south of the distribution ranges. This pattern indicates the existence of two distinct microrefugia in the Italian Peninsula and Sicily and of up to seven microrefugia in the Balkan Peninsula, but of only one refugium along the Black Sea coast of Anatolia. We identified ...

The Blue-Tongued Skink is a fascinating lizard! By virtue of the fact, like its name suggests, the lizard has a blue tongue! These interesting lizards are a member of the Skink (Scincidae) family, and they carry the genus Tiliqua. There is a whole myriad of different blue-tongues and they each carry slightly different characteristics. One thing in common, of course, is their possession of a blue tongue. Most blue tongues also have an orange belly!. Although indigenous to Australia and Indonesia, these lizards have made their way to different parts of the world whereby they are highly prized as pets. Easily tamed and docile by nature, these blue tongues make good pets for the family, and are generally safe even when handled by children. They have quite a long life span, living till 20-25 years in captivity, and growing to about 40-50cm in length (depending on the species). Blue tongues in captivity are usually fed with vegetables, fruits, cat food, eggs, snails, earthworms.. ...

FRIDAY, Oct. 2, 2020 (HealthDay News) -- What next, 2020?. In this year of surprising threats to public health, the U.S. Centers for Disease Control and Prevention is now investigating a pair of salmonella outbreaks among people who cuddled pet hedgehogs and bearded dragon lizards.. No deaths have been reported in either outbreak but a dozen people have been hospitalized, the CDC said. In both cases, health officials have not identified a common supplier. The outbreak connected with bearded dragons has sickened 13 people in eight states and seven have been hospitalized.. Ten of the sick people said theyd had contact with a bearded dragon before becoming ill. Patients reported buying bearded dragons from various pet stores in several states, the CDC said.. The outbreak linked to pet hedgehogs has sickened 32 people in 17 states. Five have been hospitalized. Sixteen of 23 ill people who were interviewed said they had contact with pet hedgehogs before they became sick.. People who became sick ...
Dave Hamilton, Martin Whiting and Sarah Pryke. Recently, the Pryke Lab published its first paper on a reptile-the iconic Frillneck Lizard (Chlamydosaurus kingii). Both males and females have frills and until now, the consensus has always been that frills play a role in anti-predator behaviour. Not only does the frill startle a would-be predator, but it may also bluff them into thinking that their potential dinner might be dangerous and risky to catch. While this hypothesis still remains to be tested, we explore an alternative hypothesis: that the frill might also play a role in sexual selection and signal fighting ability. We used optic spectrophotometry to objectively measure the colour of the frill and we also measured a range of morphological and functional traits before size matching lizards in staged contests in neutral arenas. Surprisingly, traits such as frill size, head size and bite force did not predict contest outcome. Instead, males with brighter and more colourful frills were more ...

This large arboreal lizard grows to 1.5 meters in length from head to tail, although a few specimens have grown more than 2 meters. Mature iguanas weigh between 4 and 6 kg, but some with proper diet can reach up to 8 kg. Although predominantly green, these animals are actually variable in color. Thus the color of an individual may vary based upon its sex, mood, temperature, health, or social status. Additionally, such color alteration may aide these animals in thermoregulation. In the morning, while body temperature is low, skin color will be darker, helping the lizard to absorb heat from sunlight. However, in the hot mid-day these animals become lighter or paler, helping to reflect the sun rays and minimizing the heat absorbed. Active dominant iguanas usually have a darker color than lower-ranked iguanas living in the same environment. Most color variation seen in this species is exhibited by males, and may be attributed in part to sex steroids. Six to eight weeks prior to and during courtship, ...

Variation and clonal diversity in populations of the parthenogenetic rock lizard Darevskia rostombekovi was examined by means of multilocus DNA fingerprinting using mini- and microsatellite DNA markers M13, (GATA)4, and (TCC)50). The animals examined were shown to exhibit a clonally inherited, species-specific pattern of DNA markers (fingerprint profile) that is different from the species-specific patterns of parthenogenetic species D. dahli, D. armenica, and D. unisexualis. The mean intraspecific similarity indexS was 0.950 (0.003) for a sample of 19 animals from three isolated populations of North Armenia. This significantly differed from the estimate of this parameter for a sample of 21 animals including two individuals from mountainous, relict population from the vicinity of the Sevan Lake, which was equal to 0.875 (0.001). A comparison of DNA fingerprints showed differences between 21 individuals attaining 79 DNA fragments of 1801 mini- and microsatellite markers included in the analysis. The
Last week, we broke the story of the seasons most hotly-anticipated and social distancing-friendly opening, the Gerbil Museum in London. Today, we bring you an exciting interview with Jill Young, founder of the Gecko Museum in Dallas, Texas. We dont want to get ahead of ourselves, but the emergence of pet museums may be more than a fun quarantine activity, signaling an important new industry trend.. The Mayor, Youngs lizard, was unavailable for interview due to a series of Zoom studio visits, but Young shared his artistic and culinary preferences, commented frankly on the challenges of adapting an exhibition space to reptilian climbing habits, and even gave us a scoop on not-yet-announced shows at the Gecko Museum.. * * *. Hyperallergic: Tell us a bit about your gecko.. Jill Young: His name is The Mayor! He is a crested gecko. I cant be exactly sure how old The Mayor is, as he was fully grown when I got him, but Im guessing hes around five years old now. He loves to climb and jump, and has ...

While most skink species are identified by their distinct colors and markings, certain physical characteristics apply to most of the ones found in the United States. Theyre medium-sized lizards that reach between 4 and 7 inches long as adults. Adult males of some species, like the Five Lined skink, can reach 8½ inches (including their long tail). Skinks have long slender bodies with short limbs and are protected by a smooth-scaled skin thats similar to the skin of a snake. Their coloring can be extremely flamboyant, with many species exhibiting striped patterns with vivid metallic hues. Because theyre diurnal animals-meaning they can be active both day and night-you might find them sunning along the edges of buildings or on exposed tree roots. Most skink species are also ground dwellers that travel through dense vegetation and leaf litter to hunt their prey. There are at least 15 skink species in North America. Where I live in South Carolina, I tend to see mostly Five Lined skinks, ...
yolk sac development in lizards (Lacertilia: Scincidae): New perspectives on the egg of amniotes[4] Embryos of oviparous reptiles develop on the surface of a large mass of yolk, which they metabolize to become relatively large hatchlings. Access to the yolk is provided by tissues growing outward from the embryo to cover the surface of the yolk. A key feature of yolk sac development is a dedicated blood vascular system to communicate with the embryo. The best known model for yolk sac development and function of oviparous amniotes is based on numerous studies of birds, primarily domestic chickens. In this model, the vascular yolk sac forms the perimeter of the large yolk mass and is lined by a specialized epithelium, which takes up, processes and transports yolk nutrients to the yolk sac blood vessels. Studies of lizard yolk sac development, dating to more than 100 years ago, report characteristics inconsistent with this model. We compared development of the yolk sac from oviposition to near ...
A very common myth is that reptiles are cold-blooded. In addition to describing a general temperature of reptilian blood, the term also entails the negative connotations of evil and lifelessness. To be sure, in the Biblical story of Adam and Eve, it was a serpent that deceived mankind. However, reptiles are not cold-blooded. On occasion, they are quite the contrary and can even be hot-blooded. This gradation results in reptiles being poikilothermic. Poikilotherms have a body temperature that is variable with environmental conditions. If the ambient temperature is warm or even hot, that leads to a reptile having warm or hot blood. Another physiological term that accurately depicts reptiles is ectothemy. Ectotherms control the uptake of heat from the environment as a way to control internal body temperature. Reptiles are both poikilothermic and ectothemic, but are not cold-blooded. Moreover, some larger reptiles, such as large crocodilians, sea turtles and large monitor lizards approach ...
T. nigrolutea is a large skink distributed across south-eastern mainland Australia and Tasmania. This species is torpid throughout winter with males emerging (Sept-Oct), roughly one month before females (Nov) in spring. Mating occurs in November, with gestation for approximately three months over summer. Parturition occurs in early autumn.. I have investigated the annual cycles of the sex steroids, progesterone (P4) and testosterone (T), in T. nigrolutea. Captive animals were maintained under natural lighting conditions with supplementary heat for basking. In females, plasma P4 levels increase through early pregnancy. Concentrations peak (6.3 plus or minus 2.2 ng/ml) during the second trimester (Feb) and drop to basal levels (, 1 ng/ml) before parturition. This closely resembles the pattern previously reported for the sleepy lizard, T. rugosa, and is comparable with hormone profiles during pregnancy in some other viviparous reptiles. Plasma T in males peaks (10.2 plus or minus 3.5 ng/ml) in ...
Around 150 million years ago, a hungry Compsognathus longipes chowed down on a long-tailed creature similar to a modern-day gecko. The meal may have gone down easily, but the turkey-sized dinosaur didnt survive long enough to digest it. When the dinos fossil was excavated in Germany in the nineteenth century, the early lizards remains still sat in its abdominal cavity.. Researchers have known about the preserved snack for years, and had identified it as an extinct ancient lizard called Bavarisaurus macrodactylus. But a paper recently published in the Zoological Journal of the Linnean Society points to the creatures skull anatomy to make the case that its actually a new species altogether. A researcher formerly of the American Museum of Natural History cheekily dubbed the new species Schoenesmahl dyspepsia, which, according to Nature, translates to something akin to beautiful meal that is difficult to digest.. Its not unheard of for fossils to be nestled inside other ones. In 2016, ...
The specimen, found in the Bridger Formation of southwestern Wyoming, is thought to be the earliest known example of a corytophanid, otherwise known as a casquehead or helmeted lizard, the family of reptiles that includes the so-called Jesus lizards, known for their ability to run across the surface of standing water. In addition to being likely the oldest known of its kind, the animal also appears to be a previously unknown species, one that thrived much farther north than its modern, tropical descendants do. Although modern corytophanids are restricted to Central and South America, wrote Dr. Jack Conrad, reporting the find in the journal PLOS One, I posit that the group had a Eurmerican/Laurasian origin and became restricted to lower latitudes after post-Eocene global cooling. During the Eocene epoch, which began after the extinction of the dinosaurs, the worlds land masses were somewhat similar to what we know today, but the climate was radically different. Earth was nearly ice-free, ...

Coleonyx v. variegatus is adapted to feed voraciously after deprivation of food and to withstand long periods without food. In 4 days specimens converted enough food into reserves to increase their weight by about 50 percent. Total deprivation of food resulted in very gradual loss of weight, which, if maintained, would result in 4 days of feeding being sufficient to sustain the animal for periods of 6 to 9 months. ...
Lizards and crocs are not dinosaurs nor are they descended from dinosaurs. They are reptiles. Dinosaurs were not reptiles, though they branched off from them. I should have said that birds are the only living descendants of dinosaurs instead of the only living relatives, though. They were warmblooded and have different body plans and in many cases had feathers or fur. The reptiles have 4 about evenly sized legs that just out from the side and are cold blooded.The two main groups of dinosaurs were the ones with two large hind legs and the smaller forearms and the sauropods, who had 4 legs straight under their bodies. Reptiles were better able to survive the post impact conditions than dinosaurs because they required a lot less food (part of being cold blooded). I would imagine some of the croc species died out, but a large enough number of them survived that crocs made it to the modern world. A lot of the lizard species we see probably came from smaller species of reptile ...
