Book Description
Praise for the previous edition: "An excellent source for research. Highly recommended."—The Book Report While reptiles often receive an ambivalent reaction from the public, turtles and tortoises are surely the exception. People have kept them as pets for centuries and their affection for these creatures with attractively colored shells is reflected in art, literature, and popular culture. Turtles and Tortoises of the World fills a significant gap in available literature on the chelonia turtles, tortoises, and terrapins. Noted naturalist David Alderton presents a comprehensive account of these fascinating creatures, featuring recent chelonian research. The information on lifestyle, habitat, distribution, and human involvement is clear and easy to read. Enhanced by informative maps, as well as many color and black-and-white photographs, this volume emphasizes turtles' and tortoises' diversity of form and adaptability for survival.

Book Description
Galapagos Giant Tortoises brings together researchers and conservationists to share the most up-to-date knowledge of Galapagos giant tortoises. Despite being icons of the world-famous Galapagos Archipelago and the target of more than 50 years of conservation research and management, Galapagos giant tortoise evolution and much of their ecology remained unknown until recently. This book documents the history, the pressing conservation issues, and success stories recovering several of the 15 different species of Galapagos tortoises from near extinction. The book begins with an overview of the history of the relationship between humans and Galapagos giant tortoises, starting from initial heavy exploitation of tortoises by pirates and whalers, and extending to the start of the modern conservation era in the 1960s. The book then shifts to biology, describing Galapagos tortoise evolution, taxonomy, ecology, habitats, reproduction, and behavior. Next the decades of conservation efforts and their results are reviewed, including issues of captive breeding, invasive species, introduced diseases, and de-extinction, as well as the current status and distribution of every species. The final portion of the book turns to four case studies of restoration, and then looks ahead to the future of all tortoise populations.The latest volume in the Biodiversity of the World: Conservation from Genes to Landscape series, Galapagos Giant Tortoises is a valuable resource for researchers and conservationists, as well as students of biology, wildlife conservation, and herpetology. Provides a comprehensive overview of the Galapagos giant tortoise species as written and edited by the world's leading experts Presents examples of restoration of tortoise populations following the near extinction of many of them Describes conservation strategies to ensure the full recovery of all extant species Explores recent efforts using replacement tortoises for extinct species to restore island ecosystems

Book Description
Galápagos giant tortoises are fascinating—and endangered. They live only on the Galápagos Islands, a chain of volcanic islands in the Pacific Ocean off the coast of Ecuador. These tortoises face threats from the humans who live on—and visit—the islands, as well as from Earth's warming climate. Join author Kate Messner on an a journey to the Galápagos Islands to see these incredible creatures up close and discover how cutting-edge technology is helping scientists to study and protect them.

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
One of the most recognizable animals of the Southwest, the desert tortoise (Gopherus agassizii) makes its home in both the Sonoran and Mohave Deserts, as well as in tropical areas to the south in Mexico. Called by Tohono O'odham people "komik'c-ed," or "shell with living thing inside," it is one of the few desert creatures kept as a domestic pet—as well as one of the most studied reptiles in the world. Most of our knowledge of desert tortoises comes from studies of Mohave Desert populations in California and Nevada. However, the ecology, physiology, and behavior of these northern populations are quite different from those of their southern, Sonoran Desert, and tropical cousins, which have been studied much less. Differences in climate and habitat have shaped the evolution of three races of desert tortoises as they have adapted to changes in heat, rainfall, and sources of food and shelter as the deserts developed in the last ten million years. This book presents the first comprehensive summary of the natural history, biology, and conservation of the Sonoran and Sinaloan desert tortoises, reviewing the current state of knowledge of these creatures with appropriate comparisons to Mohave tortoises. It condenses a vast amount of information on population ecology, activity, and behavior based on decades of studying tortoise populations in Arizona and Sonora, Mexico, and also includes important material on the care and protection of tortoises. Thirty-two contributors address such topics as tortoise fossil records, DNA analysis, and the mystery of secretive hatchlings and juveniles. Tortoise health is discussed in chapters on the care of captives, and original data are presented on the diets of wild and captive tortoises, the nutrient content of plant foods, and blood parameters of healthy tortoises. Coverage of conservation issues includes husbandry methods for captive tortoises, an overview of protective measures, and an evaluation of threats to tortoises from introduced grass and wildfires. A final chapter on cultural knowledge presents stories and songs from indigenous peoples and explores their understanding of tortoises. As the only comprehensive book on the desert tortoise, this volume gathers a vast amount of information for scientists, veterinarians, and resource managers while also remaining useful to general readers who keep desert tortoises as backyard pets. It will stand as an enduring reference on this endearing creature for years to come.

Book Description
An insightful exploration of the iconic Galápagos tortoises, and how their fate is inextricably linked to our own in a rapidly changing world. Finalist for the 2020 E.O. Wilson Literary Science Writing Award, sponsored by PEN America Literary Awards The Galápagos archipelago is often viewed as a last foothold of pristine nature. For sixty years, conservationists have worked to restore this evolutionary Eden after centuries of exploitation at the hands of pirates, whalers, and island settlers. This book tells the story of the islands’ namesakes—the giant tortoises—as coveted food sources, objects of natural history, and famous icons of conservation and tourism. By doing so, it brings into stark relief the paradoxical, and impossible, goal of conserving species by trying to restore a past state of prehistoric evolution. The tortoises, Elizabeth Hennessy demonstrates, are not prehistoric, but rather microcosms whose stories show how deeply human and nonhuman life are entangled. In a world where evolution is thoroughly shaped by global history, Hennessy puts forward a vision for conservation based on reckoning with the past, rather than trying to erase it. “Fresh, insightful . . . Hennessy’s melding of human and natural history makes for thought-provoking reading.” —Booklist (starred review) “Gripping . . . well-researched and thought-provoking . . . whether you’re well-versed in the intricacies of conservation or have only just begun to long for a look at the tortoises yourself. On the Backs of Tortoises is a natural history that asks important questions, and challenges us to think about how best to answer them.” —Genevieve Valentine, NPR “Wonderfully interesting, informative, and engaging, as well as scholarly.” —Janet Browne, author of Charles Darwin: Voyaging and Charles Darwin: The Power of Place
