  • Tail Bifurcation in Plestiodon Skiltonianus
    Herpetology Notes, volume 13: 343-345 (2020) (published online on 23 April 2020) Tail bifurcation in Plestiodon skiltonianus Danielle C. Miles1,*, Chasey L. Danser1, and Kevin T. Shoemaker1 Plestiodon skiltonianus (Smith, 2005), commonly The majority of tail bifurcations in other lizard species known as the Western Skink, is a smooth-scaled species are likely the result of abnormal tail regeneration after with a range from southern Idaho to northern Arizona in a lizard sheds its tail in response to a threat and are the Western United States (Tanner, 1957). The Western common across several lizard families (Clause et al. Skink is a part of the evolutionarily related skiltonianus 2006; Conzendey et al. 2013; Dudek & Ekner-Grzyb, group of lizards, of which none have previous records of 2014; Pelegrin & Leão, 2016; Tamar et al. 2013). Caudal tail bifurcation that we could find (Richmond & Reeder, 2002). Tail bifurcation is found in all of the major lizard groups and the most closely related species with this recorded observation is Plestiodon inexpectatus (Brandley et al, 2012; Koleska et al, 2017; Mitchell et al, 2012). On July 13 2019, one P. skiltonianus with a bifurcated tail was captured in a medium Sherman aluminium box trap designed for the live capture of small mammals that had been baited with bird seed and filled with biodegradable batting. As the traps were being collected at 17:00 PST, the malformed individual was found in the back of a trap, though the trap had not been triggered by its weight. The field site is at 39.4993°N, -117.0053°E on United States Forest Service land in Lander County northeast of Austin, Nevada, USA at an elevation of 1920 meters.

  • Lizard ID Guide
    Lizards of Anderson County, TN Lizards are extraordinary gifts of nature. World-wide there are close to 6,000 species. The United States is home to more than100 native species, along with many exotic species that have become established, especially in Florida. Tennessee has 9 species, 6 of which are listed for Anderson County. Some are fairly widespread and easy to observe, such as the Common Five-lined Skink below. Unfortunately, the liberal use of pesticides, combined with predation by free roaming house cats have taken a heavy toll on our lizard populations. Most lizards are insect eating machines and their ecological services should be promoted through backyard and schoolyard wildlife habitat projects. Lizard watching is great fun, and over time, observers can gain interesting insights into lizard behavior. Your backyard may be a good place to start your lizarding career. This guide will be helpful for identifying our local lizards and will also provide you with examples of lizard behaviors to observe. Some species must be captured—this can be challenging—to insure accurate identification. Please see the back page for more resources. Lizarding Lizard watching, often referred to as lizarding, will likely never be as popular as bird watching (birding), but there is an advantage to being a “lizarder.” Unlike birders, you don’t need to be an early riser. Bright sunny days with warm temperatures are the keys for successful lizarding, but like birding, close-up binoculars are helpful. A lizard’s life centers around three performance activities: 1) avoiding predators, 2) feeding, and 3) reproduction. Lizard performance is all about optimal body temperature.

Changes in vegetation structure suchasa decrease in canopy cover or an increase in herbaceous cover from prescribed fire can increase availability of preferred microhabitats for some species while simultaneously reducing preferred conditions for others. We examined the responses of herpetofaunal communities to prescribed fires in an oak/hickory forest in western Kentucky. Prescribed fires were applied twice to a 1000-ha area one and four years prior to sampling, causing changes in vegetation structure. Herpetofaunal communities were sampled using drift fences, and vegetation attributes were sampled via transects in four burned and four unburned plots. Differences in reptile community structure correlated with variation in vegetation structure largely created by fires.

Doi: http://dx.doi.org/10.15446/abc.v25n3.79707 ABSTRACT The genera Iguana and Ctenosaura belong to the Iguanidae family, and populations of most species of these genera have decreased due to anthropogenic effects. The natural history of most species of this family is poorly known, including Ctenosaura similis. Therefore, this study documents some ecological aspects of the species, such as its feeding habits, and habitat and microhabitat use in a population of Isla Contoy in Quintana Roo, Mexico. The data showed that even though C. similis is distributed throughout the island, individuals more commonly use human construction (buildings) of Parque Nacional Isla Contoy (PNIC) and mangrove areas.

  • The Ecology of Lizard Reproductive Output
    Global Ecology and Biogeography, (Global Ecol. Biogeogr.) (2011) ••, ••–•• RESEARCH The ecology of lizard reproductive PAPER outputgeb_700 1..11 Shai Meiri1*, James H. Brown2 and Richard M. Sibly3 1Department of Zoology, Tel Aviv University, ABSTRACT 69978 Tel Aviv, Israel, 2Department of Biology, Aim We provide a new quantitative analysis of lizard reproductive ecology. Com- University of New Mexico, Albuquerque, NM 87131, USA and Santa Fe Institute, 1399 Hyde parative studies of lizard reproduction to date have usually considered life-history Park Road, Santa Fe, NM 87501, USA, 3School components separately. Instead, we examine the rate of production (productivity of Biological Sciences, University of Reading, hereafter) calculated as the total mass of offspring produced in a year. We test ReadingRG6 6AS, UK whether productivity is influenced by proxies of adult mortality rates such as insularity and fossorial habits, by measures of temperature such as environmental and body temperatures, mode of reproduction and activity times, and by environ- mental productivity and diet. We further examine whether low productivity is linked to high extinction risk. Location World-wide. Methods We assembled a database containing 551 lizard species, their phyloge- netic relationships and multiple life history and ecological variables from the lit- erature. We use phylogenetically informed statistical models to estimate the factors related to lizard productivity. Results Some, but not all, predictions of metabolic and life-history theories are supported. When analysed separately, clutch size, relative clutch mass and brood frequency are poorly correlated with body mass, but their product – productivity – is well correlated with mass. The allometry of productivity scales similarly to metabolic rate, suggesting that a constant fraction of assimilated energy is allocated to production irrespective of body size.

  • I Online Supplementary Data – Henle, K. & A. Grimm-Seyfarth (2020
    Online Supplementary data – Henle, K. & A. Grimm-Seyfarth (2020): Exceptional numbers of occurrences of bifurcated, double, triple, and quintuple tails in an Australian lizard community, with a review of supernumerary tails in natural populations of reptiles. – Salamandra, 56: 373–391 Supplementary document S1. Database on bifurcation, duplication and multiplication of tails in natural populations of reptiles. We considered only data that were provided at least at the genus level and that explicitly originated from natural populations or for which this was likely, as either the authors indicated for other specimens that they were captive animals, or because museum series were examined (even if data were provided only for the specimens with accessory tails). We relaxed these criteria for pre-1900 publications and included also individuals without determination and data that were not explicitly stated as applying to wild individuals if such an origin was plausible. We extracted the following data (if available): species name, number of individuals with accessory tails, number of individuals with bifurcation, duplication, trifurcation, quadruplication, quintuplication and hexaplication, sample size, geographic origin (usually country but may also be oceanic islands), microhabitat, and the year of publication. Nomenclature follows Cogger (2014) for Australian reptiles and Uetz et al. (2019) for other species regarding generic names, name changes due to priorities and synonymies, and for subspecies identified in the source reference that have been elevated later to full species rank. Name changes due to splitting of taxa into several species were made only if allocation of the data to the new species was obvious from morphological or geographic information provided by the assessed source reference or was already done by other authors.
