western banded gecko niche

[3], The western banded gecko is a terrestrial lizard, ranging in total length (including tail) from 4–6 inches (10–15 cm). [9], The subspecific name, abbotti, is in honor of American ornithologist Clinton Gilbert Abbott. Western banded gecko is a type of gecko occurring in the southwestern United States and northern Mexico. Five subspecies are recognized. 10.2305/IUCN.UK.2007.RLTS.T64039A12739050.en. [5] The body is sandy-colored with dark crossbands broken into patches. Description: The Western Banded Gecko is a medium-sized gecko with soft skin, short limbs, a pointed snout, large eyes, and functional eyelids. [5], Predators include leaf-nosed snakes, western patch-nosed snakes, night snakes, sidewinders, western diamondback rattlesnakes, other rattlesnake species, coachwhips, and zebra-tailed lizards [8], Additional possible predators are tarantulas, large centipedes, solpugids, coyotes and kit foxes. Western Banded Gecko […] Unlike typical geckos, it has prominent eyes with movable lids. [7] Eggs hatch after six weeks. Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). Coleonyx variegatus feeds at night on insects like spiders, beetles and grasshoppers. If captured, C. variegatus may squeak and may discard its tail. 1-5) is one the most frequently encountered nocturnal reptiles in the Sonoran Desert, yet surprisingly few field studies of its ecology and life history have been published. Danger! This beautiful, delicate-looking lizard has pale pink and brown-banded translucent skin. It is usually associated with rocks or other shelters, but is also is found in sandy arroyos and dunes. Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Coleonyx. It has supple skin, uniformly granular back scales and slender toes with no pads. Predators include leaf-nosed snakes, western patch-nosed snakes, night snakes, sidewinders, western diamondback rattlesnakes, other rattlesnake species, coachwhips, and zebra-tailed lizards The Western Banded Gecko is a ground dwelling, nocturnal Gecko which is native to the Mohave and Sonoran deserts in the southwestern United States and northern Mexico. [10], The subspecific name, bogerti, is in honor of American herpetologist Charles Mitchill Bogert.[10]. The bands, which are most evident in juveniles, change into blotches and spots with age. Emerging on warm nights around 80 °F, they can be seen around porch lights looking for an easy meal, retreating if the temperature rises too high or drops too low. Active principally at night, western banded geckos can be seen crossing roads during the summer. Males are smaller and possess enlarged cloacal spurs on the base of there tale, while the females are bigger. A study investigating the deep phylogeographic structure within C. variegatus using mtDNA analyses recovered six divergent clades throughout the species' range, with topology of the mtDNA gene tree suggesting separate origins of peninsular populations with an older lineage in the south and younger one in the north. Mojave and Sonoran deserts of southeastern California, south and western Arizona and southern Nevada; southwestern Utah, southwestern New Mexico, south into Baja California and northern Mexico. As a defense mechanism, it can also curl its tails over its body to mimic a scorpion. "Introgression obscures lineage boundaries and phylogeographic history in the western banded gecko,, Creative Commons Attribution-ShareAlike License, This page was last edited on 4 September 2020, at 02:45. The Western Banded Gecko (Figs. [9] Combining the nuclear and mtDNA and applying dating analyses suggests that the peninsular clade diverged from the continental group in the Late Miocene. [8], Five subspecies of Coleonyx variegatus are recognized as being valid, including the nominotypical subspecies.[3]. [6], The western banded gecko is found in a wide range of habitats, including creosote bush and sagebrush desert, pinyon-juniper woodland, and catclaw-cedar-grama grass associations in the eastern part of its range and chaparral areas in the west. Life History . Hatchlings measure 1 inch (2.5 cm). Their tail is used to store water and fat that the species uses in times of poor feeding. The most extensive is Parker’s (1972) research on a population in South Mountain Park near Phoenix, Maricopa Co., Arizona. Its elevational range extends from below sea level to about 1,520 m (4,990 ft) asl. It is medium-sized, growing 4 to 6 inches long. Western banded geckos are the subject of an ongoing specific mark and recapture study in the red rock canyon national recreation area in southern nevada to determine population trends and densities in that area, species richness as compared to other species in the area, and basic species information. [5] Females lay up to three clutches of one to two soft-shelled eggs in the spring and summer. [9] The same study found that analyses of multilocus nuclear data provides support for four lineages, corresponding to subspecies C. v. abbotti, C. v. peninsularis, C. v. sonoriensis, and C. v. variegatus, with phylogenetic analyses indicating a single origin of the peninsular populations. Danger! The tiny scales give its skin a silky texture. The western banded gecko (Coleonyx variegatus) is a species of gecko found in the southwestern United States (southern California, southwest New Mexico, southern Arizona, Utah, Nevada) and northern Mexico (Sonora, northwest Baja California). The species is nocturnal and secretive. These geckos are believed to be able to detect the chemical signals left by snakes, which gives them the chance to avoid them If disturbed, the There are five recognized subspecies of this species. [9] This discordance is largely due to repeated episodes of mtDNA introgression that have obscured both lineage boundaries and biogeographic history. Danger! Habitat: The western banded gecko is found in open arid deserts and desert grassland, in … Western Banded Gecko EUBLEPHARIDAE Coleonyx comes from the Greek koleos, meaning a sheath and onych, meaning nail or claw, while variegatus comes from the Latin vario, meaning variegated. [1], The western banded gecko is secretive and nocturnal, foraging at night for small insects and spiders, and is one of the few reptiles that control scorpion populations by eating baby scorpions. The western banded gecko is found in open arid deserts and desert grassland, in canyons and on hillsides. The western banded gecko has movable eyelids and its pupils are vertical, distinguisng it from all other lizards in the area.
