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
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

The Natural History of the Galapagos Giant Tortoise

The Natural History of the Galapagos Giant Tortoise PDF Author: Cruz Marquez

Languages : en
Pages : 444

Book Description
The first tortoises to accidentally arrive in Galapagos 2-3 million years ago were able to adapt to their harsh environment, find one another, and establish themselves on at first one and then on at least ten islands. By the 1960's, centuries of exploitation by whalers, privateers, traders, collectors and colonists had all but eliminated these enormous lumbering beasts from the landscape. Thanks to the strenuous efforts of scientists and National Park staff, the Galapagos tortoise is once again facing a brighter future. One of these dedicated investigators, Cruz Márquez, has compiled over 40 years of research into this volume which will be an important source of information for scientists, students, naturalist guides, and conservation managers. Lavishly illustrated and including a great deal of previously published and unpublished data, this book addresses the following topics: From where did Galapagos tortoises originate? Which other tortoises are their nearest relatives? When and how did they arrive in Galapagos and spread throughout the islands? How and why did they become giants? What is known about their internal and external anatomy? Is it similar to that of marine turtles? What do giant tortoises eat? How do they adapt to different environments and seasons? Do they eat the same foods in captivity as in the wild? How do they then adapt to foraging in the wild? Do wild giant tortoises move over long distances? If so, why? Are they more active during daylight hours or at night? Why do Galapagos finches appear to feed on the skin of giant tortoises? Why are there so few opuntia cactus on Espanola Island? Is this connected to only 14 tortoises being found there in the 1970's? How do Galapagos tortoises reproduce? Do they form lasting pair bonds? Is it true that incubation temperatures can be manipulated to produce mainly male or mainly female offspring? How can we tell the difference? Do Galapagos tortoises have twins? Are there any albino tortoises? How does the fetus break through the shell? After hatching, how soon does the neonate leave the egg shell? What parasites do Galapagos tortoises have? How do these affect their health? Why are human beings responsible for the near extinction of Galapagos tortoises? What has been done for the conservation of Galapagos giant tortoises? What will be done in the future? What of Lonesome George? What efforts went into keeping the last of his species alive in captivity for almost forty years, and why? What can we learn from his death? The answers to these questions, and many more, can be found in this book.
