  • Xenosaurus Tzacualtipantecus. the Zacualtipán Knob-Scaled Lizard Is Endemic to the Sierra Madre Oriental of Eastern Mexico
    Xenosaurus tzacualtipantecus. The Zacualtipán knob-scaled lizard is endemic to the Sierra Madre Oriental of eastern Mexico. This medium-large lizard (female holotype measures 188 mm in total length) is known only from the vicinity of the type locality in eastern Hidalgo, at an elevation of 1,900 m in pine-oak forest, and a nearby locality at 2,000 m in northern Veracruz (Woolrich- Piña and Smith 2012). Xenosaurus tzacualtipantecus is thought to belong to the northern clade of the genus, which also contains X. newmanorum and X. platyceps (Bhullar 2011). As with its congeners, X. tzacualtipantecus is an inhabitant of crevices in limestone rocks. This species consumes beetles and lepidopteran larvae and gives birth to living young. The habitat of this lizard in the vicinity of the type locality is being deforested, and people in nearby towns have created an open garbage dump in this area. We determined its EVS as 17, in the middle of the high vulnerability category (see text for explanation), and its status by the IUCN and SEMAR- NAT presently are undetermined. This newly described endemic species is one of nine known species in the monogeneric family Xenosauridae, which is endemic to northern Mesoamerica (Mexico from Tamaulipas to Chiapas and into the montane portions of Alta Verapaz, Guatemala). All but one of these nine species is endemic to Mexico.

Gómez Palacio, 35070, Durango, México Submitted on 2012, 5th December; revised on 2013, 10th August; accepted on 2013, 3rd September. Abstract. The life history of a population of marbled whiptail lizard, Aspidoscelis marmorata, was examined from 1989 to 1994 in the sand dunes of the Biosphere Reserve of Mapimí, in Northern México. Lizards were studied using mark- recapture techniques. Reproduction in females occurred between May and August, with birth hatchlings matching the wet season in August. Reproductive activity was highest in the early wet season (July). Males and females reached adult size class at an average age of 1.7 years and 1.8 years, respectively. Body size of males attained an asymptote around 90 mm snout-vent length and females around 82 mm snout-vent length, at an age of approximately 3.6 years and 3.0 years, respectively. The density varied from 7 to 85 individuals / 1.0 ha. The Mexican population had late maturity, relatively long life expectancy, and fewer offspring. Overall, the observed data for A. marmorata and the expectations of life history theory for a late maturing species (K-rate selection) are in agreement.

  • Multi-National Conservation of Alligator Lizards
    MULTI-NATIONAL CONSERVATION OF ALLIGATOR LIZARDS: APPLIED SOCIOECOLOGICAL LESSONS FROM A FLAGSHIP GROUP by ADAM G. CLAUSE (Under the Direction of John Maerz) ABSTRACT The Anthropocene is defined by unprecedented human influence on the biosphere. Integrative conservation recognizes this inextricable coupling of human and natural systems, and mobilizes multiple epistemologies to seek equitable, enduring solutions to complex socioecological issues. Although a central motivation of global conservation practice is to protect at-risk species, such organisms may be the subject of competing social perspectives that can impede robust interventions. Furthermore, imperiled species are often chronically understudied, which prevents the immediate application of data-driven quantitative modeling approaches in conservation decision making. Instead, real-world management goals are regularly prioritized on the basis of expert opinion. Here, I explore how an organismal natural history perspective, when grounded in a critique of established human judgements, can help resolve socioecological conflicts and contextualize perceived threats related to threatened species conservation and policy development. To achieve this, I leverage a multi-national system anchored by a diverse, enigmatic, and often endangered New World clade: alligator lizards. Using a threat analysis and status assessment, I show that one recent petition to list a California alligator lizard, Elgaria panamintina, under the US Endangered Species Act often contradicts the best available science.

  • Reptiles of Phil Hardberger Park
    ALAMO AREA MASTER NATURALISTS & PHIL HARDBERGER PARK CONSERVANCY REPTILES OF PHIL HARDBERGER PARK ROSEBELLY LIZARD→ REPTILE= Rosebelly Lizard (picture by author) TERRESTRIAL Fred Wills is the author of this piece. VERTEBRATE Animals with backbones (vertebrates) fall into several classes. We all recognize feathered birds and hairy mammals. But what is a reptile? An easy defini- tion of reptiles is that they are terrestrial, vertebrate animals with scales or plates covering the body. However, this definition simplifies their great diversity. WITH SCALES In Texas alone, there are four major groups of reptiles: lizards, snakes, turtles, and crocodilians (alligators). Hardberger Park is home to lizards, snakes, and turtles. OR PLATES Common lizards of the park include the Rosebelly Lizard, Texas Spiny Lizard, and Ground Skink. Common snakes of the park include the Texas Rat Snake, Rough Earth Snake, and Checkered Garter Snake. Can you name any other lizards and snakes found in the area? Hint: One lizard can change color, and PHP: one snake can produce sound. ROSEBELLY LIZARD Like many birds and mammals, reptiles are predators. Small ones like the Rosebelly Lizard and Rough Earth Snake eat invertebrate animals such as insects. TEXAS SPINY LIZARD Medium-sized snakes such as the Checkered Garter Snake often eat frogs. Larger snakes, including the Texas Rat Snake, typically eat small mammals and GROUND SKINK birds. TEXAS RAT SNAKE Where do reptiles live? The various species occupy almost all kinds of habitats, from dry prairie to moist woodland, and even wetlands and streams. Re- ROUGH EARTH SNAKE lated species often divide up the habitat through differing behaviors.

  • The Importance of Assessing Climate Change Vulnerability to Address Species Conservation Karen E
    Issues and Perspectives The Importance of Assessing Climate Change Vulnerability to Address Species Conservation Karen E. Bagne,* Megan M. Friggens, Sharon J. Coe, Deborah M. Finch U.S. Department of Agriculture Forest Service, Rocky Mountain Research Station, Albuquerque, New Mexico 87102 Present address of K.E. Bagne: Department of Biology, Kenyon College, Gambier, Ohio 43022 Abstract Species conservation often prioritizes attention on a small subset of ‘‘special status’’ species at high risk of extinction, but actions based on current lists of special status species may not effectively moderate biodiversity loss if climate change alters threats. Assessments of climate change vulnerability may provide a method to enhance identification of species at risk of extinction. We compared climate change vulnerability and lists of special status species to examine the adequacy of current lists to represent species at risk of extinction in the coming decades. The comparison was made for terrestrial vertebrates in a regionally important management area of the southwestern United States. Many species not listed as special status were vulnerable to increased extinction risk with climate change. Overall, 74% of vulnerable species were not included in lists of special status and omissions were greatest for birds and reptiles. Most special status species were identified as additionally vulnerable to climate change impacts and there was little evidence to indicate the outlook for these species might improve with climate change, which suggests that existing conservation efforts will need to be intensified. Current special status lists encompassed climate change vulnerability best if climate change was expected to exacerbate current threats, such as the loss of wetlands, but often overlooked climate-driven threats, such as exceeding physiological thresholds.

Abstract The neural crest is a population of mesenchymal cells that after migrating from the neural tube give rise to a structures and cell-types: jaw, part of the peripheral ganglia and melanocytes. Although much is known about neural crest development in jawed vertebrates, a clear picture of trunk neural crest development for elasmobranchs is yet to be developed. Here we present a detailed study of trunk neural crest development in the bamboo shark, Chiloscyllium punctatum. Vital labeling with DiI and in situ hybridization using cloned Sox8 and Sox9 probes demonstrated that trunk neural crest cells follow a pattern similar to the migratory paths already described in zebrafish and amphibians. We found shark trunk neural crest along the rostral side of the somites, the ventromedial pathway, branchial arches, gut, sensory ganglia and nerves. Interestingly, Chiloscyllium punctatum Sox8 and Sox9 sequences aligned with vertebrate SoxE genes, but appeared to be more ancient than the corresponding vertebrate paralogs.

  • An Investigation of Four Rare Snakes in South-Central Kansas
    • AN INVESTIGATION OF FOUR RARE SNAKES IN SOUTH-CENTRAL KANSAS •• ·: ' ·- .. ··... LARRY MILLER 15 July 1987 • . -· • AN INVESTIGATION --OF ----FOUR ----RARE SNAKES IN SOUTH-CENTRAL KANSAS BY LARRY MILLER INTRODUCTION The New Mexico blind snake (Leptotyphlops dulcis dissectus), Texas night snake (Hypsiglena torqua jani), Texas longnose snake (Rhinocheilus lecontei tessellatus), and checkered garter snake (Thamnophis marcianus marcianus) are four Kansas snakes with a rather limited range in the state. Three of the four have only been found along the southern counties. Only the Texas longnose snake has been found north of the southern most Kansas counties. This project was designed to find out more about the range, habits, and population of these four species of snakes in Kansas. It called for a search of background information on each snake, the collection of new specimens, photographs of habitat, and the taking of notes in regard to the animals. The 24 Kansas counties covered in the investigation ranged from Cowley at the southeastern most • location to Morton at the southwestern most location to Hamilton, Kearny, Finney, and Hodgeman to the north. Most of the work centered around the Red Hills area and to the east of that area. See (Fig. 1) for counties covered. Most of the work on this project was done by me (Larry Miller). However, I was often assisted in the field by a number of other persons. They will be credited at the end of this report. METHODS A total of 19 trips were made by me between the dates of 28 March 1986 and 1 July 1987 in regard to this project.
