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.

2022 Eureka! Nonfiction Honor Book – California Reading Association Kirkus Best Indies Book List - 2022 Starred Kirkus Review: “This well-crafted success story of a species’ salvation will encourage budding environmentalists.” “A worthwhile addition to Pattison’s Another Extraordinary Animal series.” Booklist Can humans save a species from extinction? Yes! With patience, persistence, and a full dose of hope. This is the heartbreaking tale of a Galápagos giant tortoise species that was almost extinct, the herculean task of conservation work by scientists and volunteers, and a heartwarming tale of hope for our planet. In 1959, Ecuador established a national park to protect the Galápagos Islands. When they did a census, scientists found only 14 individual Española Island tortoises. The species was almost extinct. Then, they found one more Española tortoise—in the San Diego Zoo! They named him Diego and brought him back to the Galápagos for a breeding program. Ecuador established one of the most successful breeding programs in scientific history. For sixty years, scientists and hundreds of volunteers have fought valiantly to save this amazing giant tortoise species. Would it be enough? Would they be able to save the species? Read the amazing story of Diego, the giant Galápagos tortoise. Conservation is a numbers game. Each time a tortoise census is counted, it is presented in a larger font to emphasize its importance.

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.

The Galápagos giant tortoise is a symbol of the unique biodiversity of the Galápagos Islands, an emblematic species known for its impressive size and longevity. These majestic creatures boast a large, dome-shaped shell, which varies slightly in shape and size among the different species found across the islands. Typically, their carapaces are thick and bony, offering protection from predators and environmental hazards. Their skin is thick and rugged, with prominent scales on their legs, which are stout and strong, designed to support their massive bodies. The tortoises' limbs are well-adapted to moving over rough terrain, while their short, sturdy feet have a distinct elephantine appearance. Their heads are large and slightly elongated, with a pair of small, beady eyes that provide a gentle gaze. Surrounding the mouth, their skin is somewhat softer, housing a beak-like mouth adapted for grazing on grasses, leaves, and cacti-their primary food sources. Galápagos giant tortoises exhibit a range of shell shapes, including some that are saddle-backed, allowing them to stretch their necks higher to reach vegetation. This variation in shell shape has been a classic example of adaptive evolution, influenced by the differences in habitat across the islands. Adults can weigh over 400 kilograms (880 pounds) and measure more than 1.8 meters (6 feet) in length, making them the largest tortoises in the world. They are known for their slow movement, deliberate and unhurried, which, along with their impressive lifespan-often over 100 years-embodies a sense of timelessness and resilience.
