Available in PDF, EPUB and Kindle. Book excerpt: From tiny, burrowing lizards to rainforest canopy-dwellers and giant crocodiles, reptile populations everywhere are changing. Yet government and conservation groups are often forced to make important decisions about reptile conservation and management based on inadequate or incomplete data. With contributions from nearly seventy specialists, this volume offers a comprehensive guide to the best methods for carrying out standardized quantitative and qualitative surveys of reptiles, while maximizing comparability of data between sites, across habitats and taxa, and over time. The contributors discuss each method, provide detailed protocols for its implementation, and suggest ways to analyze the data, making this volume an essential resource for monitoring and inventorying reptile abundance, population status, and biodiversity. Reptile Biodiversity covers topics including: • terrestrial, marine, and aquatic reptiles • equipment recommendations and limitations • ethics of monitoring and inventory activities • statistical procedures • designing sampling programs • using PDAs in the field

Available in PDF, EPUB and Kindle. Book excerpt: Winner, 2011 Book Award, The Wildlife Society2009 Outstanding Academic Title, Choice Ernst and Lovich’s thoroughly revised edition of this classic reference provides the most updated information ever assembled on the natural histories of North American turtles. From diminutive mud turtles to giant alligator snappers, two of North America’s most prominent experts describe the turtles that live in the fresh, brackish, and marine waters north of Mexico. Incorporating the explosion of new scientific information published on turtles over the past fifteen years—including the identification of four new species—Ernst and Lovich supply comprehensive coverage of all fifty-eight species, with discussions of conservation status and recovery efforts. Each species account contains information on identification, genetics, fossil record, distribution, geographic variation, habitat, behavior, reproduction, biology, growth and longevity, food habits, populations, predators, and conservation status. The book includes range maps for freshwater and terrestrial species, a glossary of scientific names, an extensive bibliography for further research, and an index to scientific and common names. Logically organized and richly illustrated—with more than two hundred color photographs and fifty-two maps—Turtles of the United States and Canada remains the standard for libraries, museums, nature centers, field biologists, and professional and amateur herpetologists alike.

Download or read book Biology and Conservation of North American Tortoises written by David C. Rostal and published by JHU Press. This book was released on 2014-08-01 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive book ever published on North America's native tortoises. Tortoises, those unmistakable turtles, evolved from a lineage that split off from the familiar pond turtles roughly 100 million years ago. Over time, these plant-eating land turtles spread around the world, growing to an enormous size (depending on the species) and living so long that they have become the stuff of legends. By most accounts, they are indeed the longest-lived of the turtles, with good records suggesting individuals may live as long as 180 years (anecdotal records suggest that some reach ages of 200 years or more). Providing the first comprehensive treatment of North America’s tortoises, Biology and Conservation of North American Tortoises brings together leading experts to give an overview of tortoise morphology, taxonomy, systematics, paleontology, physiology, ecology, behavior, reproduction, diet, growth, health, and conservation. The contributors carefully combine their own expertise and observations with results from studies conducted by hundreds of other researchers. The result is a book that belongs in the library of every herpetologist. Contributors Gustavo Aguirre L. Linda J. Allison Matthew J. Aresco Roy C. Averill-Murray Joan E. Berish Kristin H.

Book excerpt: In July 1993 a remarkable group of ecologists, conservationists, land managers, government officials, & policy-makers representing 25 nations gathered at Purchase, New York, to attend a conference devoted to the conservation, restoration, & management of tortoises & turtles. Offering just a glimpse of the troubled conservation status of the world's 270-plus species of tortoises & turtles, the 77 papers & summary reports (as well as abstracts of presented posters) included in the proceedings represent the combined efforts of more than 130 authors & 35 reviewers. The material presented in this 494-page volume, organized by the major subject areas of the 1993 conference, roughly corresponds to the daily sessions of the meeting: Direct & Indirect Threats to Habitat; Direct Loss of Population - Disease, Predation, & Human Exploitation; Breeding, Repatriation, & Relocation; Applications of Demography, Ecology, & Genetics to Conservation; Status Reports; Species Recovery & Management Strategies; Reserves & Programs; & Integrated Management Strategies & Public Policy. Abstracts of the presented posters appear in a separate section. "Together the papers in this volume lay the groundwork for what one might call a theoretical basis for the science of chelonian conservation, an exercise that has never been attempted before."--Peter C. H. Pritchard, author ENCYCLOPEDIA OF TURTLES. Direct inquiries to: [email protected].

Download or read book Effects of Habitat Quality on Reproduction in Two Georgia Populations of Gopherus Polyphemus written by Jacqueline Entz and published by . This book was released on 2009 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's Abstract: The purpose of this study was to examine differences in maternal investment by examining variation in the habitat structure and reproductive parameters for two populations of Gopherus polyphemus in Southeast GA. Both habitat structure and reproductive parameters for these populations are known from a previous study, thus this study expands upon the previous one and addresses four main questions. (1) Has habitat quality changed in the past ten years within and between population sites? (2) Could a change of habitat have affected female morphology or female reproductive parameters within or between populations? (3) Is female body size shaping egg size and/or clutch size for either population? (4) Are females providing equal resources to hatchlings and is hatchling growth potentially being modified by habitat quality affecting adult size and age to sexual maturity? Tortoises were captured by bucket trapping and hand trapping. Radio-graphs were used to obtain information about female body size, clutch size and egg size. In order to assess the effect of habitat quality on tortoises, hatchlings from both locations were reared under controlled, laboratory conditions. The hatchlings were measured bi-weekly to determine differences in growth. Results indicate that habitat quality for these two populations has not changed in the past fourteen years, indicating that this habitat is slow to change. In response to limited change in habitat quality, female body size and reproductive parameters have not changed. Female tortoises from one population produced significantly larger clutch sizes than the other, even when female body size was accounted for; this trend has been observed in many other Testudine species. When hatchling sizes were compared to other populations of G. polyphemus, the hatchling SCL seems consistent while the hatchling mass is variable. Thus, we believe that in Gopherus polyphemus female body size plays a small role in clutch size determination and no role on egg size determination. It is believed that G. polyphemus is minimizing hatchling size (SCL) in order to maximize clutch size and those females with access to more resources can supply more yolk to developing embryos. When hatchlings from both populations were provided with equal resources they grew at similar rates, indicating that the poorer quality habitat at GLS leads to a slower growth rate. Therefore, habitat quality is playing a major role in tortoise growth rates and reproduction. Based on these results, conservation efforts are needed to maintain healthy tortoise populations need to address habitat quality in development of management plans.

This book was released on 2012-04-14 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for ecologists interested in capturing their understandings of how natural systems work in software – to help inform their work and communicate the consequences of proposed management plans. Historically, ecologists had to rely on the skills of trained computer programmers to modeling natural systems, but now a new generation of software is allowing ecologists to directly capture their understandings of systems in software. This book is a compilation of spatially explicit simulation models developed by ecologists and planners without any formal computer programming skills. Readers will be inspired to believe that they too can create similar models of the systems with which they are familiar.
