Herpetological Journal FULL PAPER
Volume 27 (April 2017), 201–216 Herpetological Journal FULL PAPER Published by the British Predation of Jamaican rock iguana Cyclura( collei) nests Herpetological Society by the invasive small Asian mongoose (Herpestes auropunctatus) and the conservation value of predator control Rick van Veen & Byron S. Wilson Department of Life Sciences, University of the West Indies, Mona 7, Kingston, Jamaica The introduced small Asian mongoose (Herpestes auropunctatus) has been widely implicated in extirpations and extinctions of island taxa. Recent studies and anecdotal observations suggest that the nests of terrestrial island species are particularly vulnerable to mongoose predation, yet quantitative data have remained scarce, even for species long assumed to be at risk from the mongoose. We monitored nests of the Critically Endangered Jamaican Rock Iguana (Cyclura collei) to determine nest fate, and augmented these observations with motion-activated camera trap images to document the predatory behaviour of the mongoose. Our data provide direct, quantitative evidence of high nest predation pressure attributable to the mongoose, and together with reported high rates of predation on hatchling and juvenile iguanas (also by the mongoose), support the original conclusion that the mongoose was responsible for the apparent lack of recruitment and the aging structure of the small population that was ‘re-discovered’ in 1990. Encouragingly however, our data also demonstrate a significant reduction in nest predation pressure within an experimental mongoose-removal area. Thus, our results indicate that otherwise catastrophic levels of nest loss (at or near 100%) can be ameliorated or even eliminated by removal trapping of the mongoose. We suggest that such targeted control efforts could also prove useful in safeguarding other threatened insular species with reproductive strategies that are notably vulnerable to mongoose predation (e.g., the incubation of eggs on or underground). -
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. -
Systematic Revision of the Early Miocene Fossil Pseudoepicrates
Zoological Journal of the Linnean Society, 2018, XX, 1–18. With 10 figures. Systematic revision of the early Miocene fossil Pseudoepicrates (Serpentes: Boidae): implications for the evolution and historical biogeography of the West Indian boid snakes (Chilabothrus) SILVIO ONARY1* AND ANNIE S. HSIOU1 1Departamento de Biologia, Laboratório de Paleontologia de Ribeirão Preto, Faculdade de Filosofia Ciências e Letras de Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto, São Paulo, Brazil. Received 20 June 2017; revised 28 November 2017; accepted for publication 23 December 2017 The taxonomy of the early Miocene genus Pseudoepicrates is controversial. Originally interpreted as the viperid Neurodromicus, subsequent work deemed the material to represent an extinct boid, Pseudoepicrates stanolseni. However, more recent work considered Pseudoepicrates to be a synonym of the extant Boa constrictor. Due to these conflicting interpretations, we provide a revision of the systematic affinities of P. stanolseni. This redescription was based on the first-hand analysis of all material of Pseudoepicrates, together with the comparison of extant boids. Our findings suggest that, in addition to being an invalid taxon, ‘Pseudoepicrates’ cannot be referred to B. constric- tor. Instead, the extant Chilabothrus is here regarded as the most cogent generic assignment, with Chilabothrus stanolseni comb. nov. proposed for the extinct species. The referral of this material to Chilabothrus suggests that the genus originated as early as ~18.5 Mya. The revised history of this record has interesting implications for our understanding of the early divergence of the group. The presence of Chilabothrus in the early Miocene of Florida supports biogeographical hypotheses, which suggest that the genus reached the West Indian island complex around 22 Mya, dispersing into the North American territory by at least 18.5 Mya. -
