Publisher: University of Georgia Press
ISBN: 9780820329024
Category : Nature
Languages : en
Pages : 270

Book Description
Seventy-five percent of the turtle species in the United States can be found in the Southeast. In fact, the region is second only to parts of Asia in its number of native turtles. Filled with more than two hundred color photographs and written with a special focus on conservation, this guide covers forty-five species of this nonthreatening, ancient lineage of long-lived reptiles. Heavily illustrated, fact-filled descriptions of each species and its habitat comprise the heart of the book. Species accounts cover such information as descriptions of adults and hatchlings; key identifiers including size, distinctive characters and markings; land, river, pond, and wetland habitats; behaviors and activities; food and diet; reproduction; predators and defense; and conservation issues. Also included is a wealth of general information about the importance of turtle conservation and the biology, diversity, and life history of turtles. Discussed are distinguishing turtle characteristics; differences among turtles, tortoises, and terrapins; shell structure and architecture; reproduction and longevity; turtle predators and defense mechanisms; and turtle activities such as basking, hibernation, aestivation, and seasonal movement. Useful information about the interactions of humans and turtles is also covered: species that are likely to be commonly encountered, turtles as pets, and more. Clearly written, cleanly designed, and fun to use, the guide will promote a better understanding of the habitat needs of, and environmental challenges to, this fascinating group of animals. Features: In-depth descriptions of the forty-two native species Conservation-oriented approach More than two hundred color photographs Nearly forty distribution maps Clear descriptions of each species, including differences in the appearance of young and mature turtles “Did You Know?” sidebars of interesting turtle facts Size charts; key identifiers; and information about habitat, behavior and activity, food and feeding, reproduction, predators and defense, and conservation

Turtles as Hopeful Monsters

Turtles as Hopeful Monsters PDF Author: Olivier Rieppel
Publisher: Indiana University Press
ISBN: 0253025079
Category : Science
Languages : en
Pages : 216

Book Description
Where do turtles hail from? Why and how did they acquire shells? These questions have spurred heated debate and intense research for more than two hundred years. Brilliantly weaving evidence from the latest paleontological discoveries with an accessible, incisive look at different theories of biological evolution and their proponents, Turtles as Hopeful Monsters tells the fascinating evolutionary story of the shelled reptiles. Paleontologist Olivier Rieppel traces the evolution of turtles from over 220 million years ago, examining closely the relationship of turtles to other reptiles and charting the development of the shell. Turtle issues fuel a debate between proponents of gradual evolutionary change and authors favoring change through bursts and leaps of macromutation. The first book-length popular history of its type, this indispensable resource is an engaging read for all those fascinated by this ubiquitous and uniquely shaped reptile.

Turtles, Tortoises and Terrapins

Turtles, Tortoises and Terrapins PDF Author: Ronald Isaac Orenstein
Publisher:
ISBN:
Category : Turtles
Languages : en
Pages : 328

Book Description
This book surveys the myriad of turtle anatomy, habitat, & life cycles throughout the ages. Project director of the International Wildlife Coalition, Orenstein presents a popular book about turtles, the term he uses for almost all marine, aquatic, and terrestrial species of the order Testudines. His own background is in ornithology rather than herpetology, but his work in wildlife conservation has made him aware of the plight of turtles throughout the world, and hopes people will help protect them if they get to know them a little better. He includes many color photographs. Turtles, almost alone among reptiles, have earned both human interest and affection. Our fascination with turtles, though, has not helped them much. Sought after for food, as pets, and for tortoiseshell, their habitats under attack on land and sea, turtle populations are in decline around the world. Understanding turtles is not only interesting, but also important. Turtles, tortoises, and terrapins have been on earth since the Triassic Period, approximately 200 million years ago. Their exact origins are uncertain, though - it is still unclear from which group of reptiles turtles sprang. Although the earliest fossils are clearly turtles, their anatomy has changed dramatically over time. In addition, turtle species vary greatly in such basic characteristics as anatomy and habitat preferences. Turtles, Tortoises and Terrapins surveys the myriad of turtle anatomy, habitat, and life cycles throughout the ages. Human activities on the land and at sea pose the greatest threat that turtles have faced in the last 200 million years. The battle to save turtles goes on, and this book provides an important voice in turtle ecology. Turtles, Tortoises and Terrapins is the perfect resource for anyone interested in all facets of these amazing and diverse reptiles.

Book Description
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.

Sea Turtles of the Atlantic and Gulf Coasts of the United States

Sea Turtles of the Atlantic and Gulf Coasts of the United States PDF Author: Carol Ruckdeschel
Publisher: University of Georgia Press
ISBN: 082034446X
Category : Nature
Languages : en
Pages : 151

Book Description
Written by two of the Southeast's foremost authorities on sea turtle conservation, this is an accessible, fully illustrated guide to the species that frequent the Atlantic and Gulf Coasts of the United States. No one who encounters a sea turtle soon forgets it. The leatherback, for instance, can grow to huge proportions, commonly approaching eight feet in length and more than half a ton in weight. Powerful swimmers, they are also among the deepest divers of all air-breathing sea creatures. Despite these assets, the survival of the leatherback, like that of all sea turtle species, is under constant threat from commercial fishing operations, overdevelopment of nesting grounds, pollution, and predation by introduced species. The guide opens with comprehensive coverage of the sea turtle's evolution, juvenile and adult life cycles, nesting, diet and feeding, disease and parasites, predators, and conservation issues. Each subsequent chapter is dedicated to a particular turtle species: loggerhead, leatherback, Kemp's ridley, green sea turtle, hawksbill, and olive ridley. The account of each species describes distribution, habitats, general appearance, life history and behavior, and conservation. For each species, photographs of hatchlings and adults and a map showing distribution and migration provide further information. Sea turtles have been swimming the seas for one hundred million years. Yet all of the species in this book—indeed, all sea turtles worldwide—are on U.S. and international endangered lists. Biologists Carol Ruckdeschel and C. Robert Shoop have dedicated their careers to learning about sea turtles—and to ensuring that we understand that we are stakeholders in the fate of these ancient creatures. With this guide in hand, readers will be better equipped to understand sea turtle biology and support sea turtle conservation efforts.

Book Description
The people of Vassilikos, farmers and tourist entrepreneurs on the Greek island of Zakynthos, are involved in a bitter environmental dispute concerning the conservation of sea turtles. Against the environmentalists' practices and ideals they set their own culture of relating to the land, cultivation, wild and domestic animals. Written from an anthropological perspective, this book puts forward the idea that a thorough study of indigenous cultures is a fundamental step to understanding conflicts over the environment. For this purpose, the book offers a detailed account of the cultural depth and richness of the human environmental relationship in Vassilikos, focusing on the engagement of its inhabitants with diverse aspects of the local environment, such as animal care, agriculture, tourism and hunting.
