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

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.

For millennia the mighty giant tortoises lived in isolation on remote oceanic islands such as the Galapagos, Seychelles and Mauritius. Then in the sixteenth century sailors discovered that they were good to eat, and their strategic location led to a wholesale plunder of their population by passing ships. Later, many Victorian scientists became fascinated with these creatures, directly inspiring the first understanding of ecology and biogeography and Darwin's theory of natural selection. The giant tortoise was also the subject of the world's first conservation fight in the 1870s. Indeed many people's lives have been touched by these gentle giants. The French were happy to surrender the island of Mauritius in 1810, but baulked at handing over their mascot tortoise, and the British and American governments were forced to concede the tortoises in a major Cold War incident. The twentieth century saw the establishment of wildlife reserves in the Galapagos and elsewhere, but it has been too late for many species. However, modern genetics has been able to track down members of what were once believed to be extinct populations. A Sheltered Life is a fascinating look at one of the world's strangest and most wondrous animals--whose significance in modern science and culture cannot be underestimated.

Tortoises may be the first family of higher animals to become extinct in the coming decades. They are losing the survival race because of what distinguishes them, in particular their slow, steady pace of life and reproduction. The Last Tortoise offers an introduction to these remarkable animals and the extraordinary adaptations that have allowed them to successfully populate a diverse range of habitats—from deserts to islands to tropical forests. The shields that protect their shoulders and ribs have helped them evade predators. They are also safeguarded by their extreme longevity and long period of fertility. Craig Stanford details how human predation has overcome these evolutionary advantages, extinguishing several species and threatening the remaining forty-five. At the center of this beautifully written work is Stanford's own research in the Mascarene and Galapagos Islands, where the plight of giant tortoise populations illustrates the threat faced by all tortoises. He addresses unique survival problems, from genetic issues to the costs and benefits of different reproductive strategies. Though the picture Stanford draws is bleak, he offers reason for hope in the face of seemingly inevitable tragedy. Like many intractable environmental problems, extinction is not manifest destiny. Focusing on tortoise nurseries and breeding facilities, the substitution of proxy species for extinct tortoises, and the introduction of species to new environments, Stanford's work makes a persuasive case for the future of the tortoise in all its rich diversity.

Formed of dramatic volcanic scenery and home to marvellous beasts, it is little wonder that the first name for the Galpagos archipelago was Las Encantadas: the enchanted islands. In this captivating natural history, Henry Nicholls builds up the ecology of these famous islands, from their explosive origins to the arrival of the archipelago's celebrated reptiles and ultimately humans. It's a story of change, as the islands are transformed from lava-strewn wilderness into a vital scientific resource and a sought-after destination for eco-enthusiasts. Charles Darwin's five-week visit to the Galpagos in 1835 played a pivotal role in this transformation. At the time, he was more interested in rocks than finches, took the opportunity to ride on the backs of tortoises and fling iguanas into the sea. Yet the Galpagos experience can be an inspiration and it certainly was for Darwin, pointing him towards one of the most important and influential ideas in the history of humankind: evolution by natural selection. And with the Darwin connection, the Galpagos found itself propelled onto a global stage. But worldwide fame has brought with it nearly 200,000 tourists a year and a human population now estimated at around 30,000. If Darwin learned from the Galpagos, so we must too. For what happens here in years to come foreshadows the fate of threatened ecosystems everywhere on earth.

Excerpt: The Galapagos tortoise or Galapagos giant tortoise (Chelonoidis nigra) is the largest living species of tortoise, reaching weights of over 400 kg (880 lb) and lengths of over 1.8 meters (5.9 ft). With life spans in the wild of over 100 years, it is one of the longest-lived vertebrates. A captive individual lived at least 170 years. The tortoise is native to seven of the Galapagos Islands, a volcanic archipelago about 1,000 km (620 mi) west of the Ecuadorian mainland. Spanish explorers who discovered the islands in the 16th century named them after the Spanish galapago, meaning tortoise. Shell size and shape vary between populations. On islands with humid highlands, the tortoises are larger, with domed shells and short necks. On islands with dry lowlands, the tortoises are smaller, with "saddleback" shells and long necks. These island-to-island differences played a role in the inception of Charles Darwin's theory of evolution. Tortoise numbers declined from over 250,000 in the 16th century to a low of around 3,000...

An insightful exploration of the iconic Galápagos tortoises, and how their fate is inextricably linked to our own in a rapidly changing world 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.
