Download or read book The Influence of Landscape on Genetic Divergence of the Prairie Ring necked Snake Diadophis Punctatus Arnyi in Missouri written by María Eugenia.. Degano and published by . This book was released on 2019 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Changes in land use can result in habitat fragmentation, which threatens population viability. Reptiles may be more susceptible to the effects of fragmentation because of their limited dispersal and sensitivity to environmental conditions, which will ultimately impact gene flow among remnant populations. In this study, I used the spatial distribution of Diadophis punctatus arnyi to test hypotheses of landscape effects on the genetic structure of 10 sampling sites in northern Missouri. Genetic distance (FST) among populations was based on six microsatellite markers, and I tested the observed genetic differentiation against a suite of alternative resistance surfaces representing biologically plausible hypotheses of how Ring-necked Snakes perceive the landscape. I modeled distances matrices based on putative movement barriers, Euclidean distance, roads and land cover permeability through accumulated cost of least-cost paths, and evaluated their performance using Mantel tests, two causal modelling frameworks, and the mixed-model maximum-likelihood population-effects approach. All methods performed well showing the significant effect of the Missouri River on the genetic isolation of populations on either side, followed by the effects of roads and wetlands. This study sheds light on resistance to movement by snakes based on changes in land use. The presence of roads and frequently flooded habitats were the primary potential landscape features that hinder habitat connectivity among populations."--Abstract.

Download or read book North American Box Turtles written by C. Kenneth Dodd and published by University of Oklahoma Press. This book was released on 2002 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once a familiar backyard visitor in many parts of the United States and Mexico, the box turtle is losing the battle against extinction. In North American Box Turtles, C. Kenneth Dodd, Jr., has written the first book-length natural history of the twelve species and subspecies of this endangered animal. This volume includes comprehensive information on the species’ evolution, behavior, courtship and reproduction, habitat use, diet, population structure, systematics, and disease. Special features include color photos of all species, subspecies, and their habitats; a simple identification guide to both living and fossil species; and a summary of information on fossil Terrapene and Native uses of box turtles. End-of-chapter sections highlight future research directions, including the need for long-term monitoring and observation of box turtles within their natural habitat and conservation applications. A glossary and a bibliography of literature on box turtles accompany the text. All royalties from the sales of this volume will go to the Chelonian Research Foundation, a nonprofit foundation for the conservation of turtles.
Download or read book The Amphibians and Reptiles of Alberta written by Anthony Patrick Russell and published by University of Calgary Press. This book was released on 2000 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphibians and reptiles (herpetofauna) are a significant but much-neglected component of the natural economy of the province of Alberta. The Amphibians and Reptiles of Alberta, Second Edition continues both as a field guide and a comprehensive natural history, builds on the strengths of the first with a richly illustrated text and colour photographs of the species taken by renowned wildlife photographer Wayne Lynch. The Amphibians and Reptiles of Alberta, First Edition won an Emerald Award for Environmental Excellence and an award from the Book Publishers Association of Alberta. This second edition has been thoroughly revised and updated. Nomenclature has been changed to reflect current thinking in the field. New photographs have been added, and maps and illustrations have been updated. This is the essential reference for Alberta herpetofauna.

Available in PDF, EPUB and Kindle. Book excerpt: "Mesozoic Birds is the first book to bring together world-renowned specialists on fossil birds and their importance to avian origins and, more importantly, it stresses a unified approach (cladistics) and presents the most anatomically detailed analyses available to date. No other study or collection of studies has ever done so much. How could the project not be welcomed by its audience of paleontologists, ornithologists, and evolutionary biologists!"—David Weishampel, editor of The Dinosauria "This is the first comprehensive volume dedicated to the relationships and evolution of the birds that lived during the Age of Dinosaurs. Its wealth of information and its diversity of viewpoints will ensure that this indispensable volume is used and discussed for many years to come."—Kevin Padian, University of California, Berkeley
Download or read book Toxins and Drug Discovery written by P. Gopalakrishnakone and published by Springer. This book was released on 2019-09-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the field of Toxinology has expanded substantially. On the one hand it studies venomous animals, plants and micro organisms in detail to understand their mode of action on targets. While on the other, it explores the biochemical composition, genomics and proteomics of toxins and venoms to understand their three interaction with life forms (especially humans), development of antidotes and exploring their pharmacological potential. Therefore, Toxinology has deep linkages with biochemistry, molecular biology, anatomy and pharmacology. In addition, there is a fast developing applied subfield, clinical toxinology, which deals with understanding and managing medical effects of toxins on human body. Given the huge impact of toxin-based deaths globally, and the potential of venom in generation of drugs for so-far incurable diseases (for example, Diabetes, Chronic Pain), the continued research and growth of the field is imminent. This has led to the growth of research in the area and the consequent scholarly output by way of publications in journals and books. Despite this ever growing body of literature within biomedical sciences, there is still no all-inclusive reference work available that collects all of the important biochemical, biomedical and clinical insights relating to Toxinology. The Handbook of Toxinology aims to address this gap and cover the field of Toxinology comprehensively.
