Turtle conservation groups in partnership with PARC have designated 2011 as the Year of the Turtle.

AN INTRODUCTION to Texas Turtles
TEXAS PARKS AND WILDLIFE AN INTRODUCTION TO Texas Turtles Mark Klym An Introduction to Texas Turtles Turtle, tortoise or terrapin? Many people get confused by these terms, often using them interchangeably. Texas has a single species of tortoise, the Texas tortoise (Gopherus berlanderi) and a single species of terrapin, the diamondback terrapin (Malaclemys terrapin). All of the remaining 28 species of the order Testudines found in Texas are called “turtles,” although some like the box turtles (Terrapene spp.) are highly terrestrial others are found only in marine (saltwater) settings. In some countries such as Great Britain or Australia, these terms are very specific and relate to the habit or habitat of the animal; in North America they are denoted using these definitions. Turtle: an aquatic or semi-aquatic animal with webbed feet. Tortoise: a terrestrial animal with clubbed feet, domed shell and generally inhabiting warmer regions. Whatever we call them, these animals are a unique tie to a period of earth’s history all but lost in the living world. Turtles are some of the oldest reptilian species on the earth, virtually unchanged in 200 million years or more! These slow-moving, tooth less, egg-laying creatures date back to the dinosaurs and still retain traits they used An Introduction to Texas Turtles | 1 to survive then. Although many turtles spend most of their lives in water, they are air-breathing animals and must come to the surface to breathe. If they spend all this time in water, why do we see them on logs, rocks and the shoreline so often? Unlike birds and mammals, turtles are ectothermic, or cold- blooded, meaning they rely on the temperature around them to regulate their body temperature. -

A Significant Range Extension for the Texas Map Turtle (Graptemys Versa) and the Inertia of an Incomplete Literature
Herpetological Conservation and Biology 9(2):334−341. Submitted: 3 January 2014; Accepted 15 February 2014; Published: 12 October 2014. A SIGNIFICANT RANGE EXTENSION FOR THE TEXAS MAP TURTLE (GRAPTEMYS VERSA) AND THE INERTIA OF AN INCOMPLETE LITERATURE PETER V. LINDEMAN Department of Biology and Health Services, Edinboro University of Pennsylvania, 230 Scotland Road, Edinboro, PA 16444, USA, e-mail: [email protected] Abstract.—Defining the limits of a species’ geographic distribution is fundamental to research in biogeography, ecology, and conservation biology. The Texas Map Turtle, Graptemys versa, is endemic to the Colorado River drainage in central Texas but has been incorrectly reported by several sources to be restricted to the part of the Colorado drainage located on the Edwards Plateau, northwest of the fault lines of the Balcones Escarpment. I conducted visual surveys of basking turtles, vouchered with photographs, which demonstrate that even statements that the species occurs mainly above the Balcones Escarpment are incorrect. I observed higher numbers and higher relative abundances within basking turtle assemblages throughout the five counties downstream of the Edwards Plateau, in over 400 river km of the Colorado, and an abundant population was observed just 48 river km from the river’s mouth in coastal Matagorda County. Literature statements regarding restricted limits of freshwater turtle geographic ranges should be critically appraised for their accuracy. Surveys that are conducted beyond published range limits must also be detailed not just for new records but also for negative results, in order to enable future workers to properly evaluate statements about range limits. Key Words.—Balcones Escarpment; Colorado River; Edwards Plateau; range limits; relative abundance; Texas INTRODUCTION one or more range states (Lindeman 2013). -
Aspects of the Life History of the Texas Map Turtle (Graptemys Versa)
Am. Midl. Nat. 153:378–388 Aspects of the Life History of the Texas Map Turtle (Graptemys versa) PETER V. LINDEMAN1 Department of Biology and Health Services, 150 Cooper Hall, Edinboro University of Pennsylvania, Edinboro 16444 ABSTRACT.—The Texas map turtle (Graptemys versa) is endemic to the Colorado River drainage in southcentral Texas. A study of its life history was undertaken using data collected in 1998–2000 from a population in the South Llano River, southernmost tributary of the Colorado drainage, and data from museum specimens that had been collected from the South Llano River in 1949. Compared to congeners, G. versa is a small-bodied species. Its small body size is, predictably, linked to relatively small clutch size, small egg size, rapid growth toward asymptotic size and early maturation. As many as four clutches may be laid during an active season, although the effects of follicular atresia on clutch frequency are not known. Both clutch size and egg width were positively correlated with female body size, with the former relationship having a log-log slope significantly less than the expected value of 3, probably due to the latter relationship. Analyses were consistent with the hypothesis of anatomical constraint on egg size, with at least smaller females laying eggs that are of less than optimal size. No differences were found in body size or clutch size between 1949 and 1998–2000 despite a large- scale change in diet associated with invasion of the river by Asian clams (Corbicula sp.). However, body size is substantially reduced in the South Llano River compared to other sections of the Colorado drainage, a finding mimicked by at least one other turtle species in the drainage, Pseudemys texana. -

Box 222 Ha Noi, Vietnam Tel/Fax: +84 4 3514 8850 Email: [email protected] Website: www.envietnam.org March 9, 2010 Press Release NEW CHELONIAN VISITOR CENTER PROMOTES CONSERVATION OF VIETNAM’S TORTOISES AND FRESHWATER TURTLES Hanoi, March 10, 2010 – Cuc Phuong National Park opened the doors to the region’s first visitor interpretation center focused exclusively on the conservation and protection of tortoises and freshwater turtles. Located on the grounds of the park’s Turtle Conservation Center (TCC), the new educational facilities incorporate a range of interpretive displays and exhibits including underwater viewing tanks, a turtle egg incubation and hatchling room, and a mock hunting camp and forest trail. This new educational component of the park’s turtle conservation center was developed to promote efforts to protect turtles amongst the park’s approximately 80,000 annual visitors. “We hope the new Chelonian Interpretation Center will help the public understand more about turtles and the crisis our turtles face as a result of hunting and trade,” says Bui Dang Phong, Vice Director of Wildlife Conservation and Rescue Centers at Cuc Phuong National Park. “Vietnam’s turtles are being hunted to the point of extinction. Many species’ survival may be contingent upon getting the public to understand the problem and actively becoming involved in their protection.” ENV also marks the opening of the center with the release of two new important resources intended to support law enforcement agencies in their efforts to reduce the illegal trade of turtles. A short film produced by ENV on the Asian turtle crisis provides forest rangers and park managers with an introduction to turtles and an overview of the threats they face, as well as some basic information on dealing with confiscations. -
