Summary : 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

Summary : 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.

Summary : 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.

Summary : 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.

Summary : This lush book of photography represents National Geographic's Photo Ark, a major cross-platform initiative and lifelong project by photographer Joel Sartore to make portraits of the world's animals-especially those that are endangered. His powerful message, conveyed with humor, compassion, and art- to know these animals is to save them.Sartore intends to photograph every animal in captivity in the world. He is circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species, with an emphasis on those facing extinction. He has photographed more than 6,000 already and now, thanks to a multi-year partnership with National Geographic, he may reach his goal. This book showcases his animal portraits- from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Paired with the eloquent prose of veteran wildlife writer Douglas Chadwick, this book presents a thought-provoking argument for saving all the species of our planet.

Summary : Lonesome George is a 5ft long, 200lb tortoise aged between 60 and 200. In 1971 he was discovered on the remote Galapagos island of Pinta, from which tortoises had supposedly been exterminated by greedy whalers and seal hunters. He has been at the Charles Darwin Research Station on Santa Cruz island ever since, on the off-chance that scientific ingenuity will conjure up a way of reproducing him and resurrecting his species. Meanwhile a million tourists and dozens of baffled scientists have looked on as the celebrity reptile shows not a jot of interest in the female company provided. Today, Lonesome George has come to embody the mystery, complexity and fragility of the unique Galapagos archipelago. His story echoes the challenges of conservation worldwide; it is a story of Darwin, sexual dysfunction, adventure on the high seas, cloning, DNA fingerprinting and eco-tourism.

Summary : The Mascarene islands in the southern Indian Ocean - Mauritius, Réunion and Rodrigues - were once home to an extraordinary range of birds and reptiles. Evolving on these isolated volcanic islands in the absence of mammalian predators or competitors, the land was dominated by giant tortoises, parrots, skinks and geckos, burrowing boas, flightless rails & herons, and of course (in Mauritius) the Dodo. Uninhabited and only discovered in the 1500s, colonisation by European settlers in the 1600s led to dramatic changes in the ecology of the islands; the birds and tortoises were slaughtered indiscriminately while introduced rats, cats, pigs and monkeys destroyed their eggs, the once-extensive forests logged, and invasive introduced plants from all over the tropics devastated the ecosystem. The now-familiar icon of extinction, the Dodo, was gone from Mauritius within 50 years of human settlement, and over the next 150 years many of the Mascarenes' other native vertebrates followed suit. The product of over 30 years research by Anthony Cheke, Lost Land of the Dodo provides a comprehensive yet hugely enjoyable account of the story of the islands' changing ecology, interspersed with human stories, the islands' biogeographical anomalies, and much else. Many French publications, old and new, especially for Réunion, are discussed and referenced in English for the first time. The book is richly illustrated with maps and contemporary illustrations of the animals and their environment, many of which have rarely been reprinted before. Illustrated box texts look in detail at each extinct vertebrate species, while Julian Hume's superb colour plates bring many of the extinct birds to life. Lost Land of the Dodo provides the definitive account of this tragic yet remarkable fauna, and is a must-read for anyone interested in islands, their ecology and the history of our relationship with the world around us.

Summary : A lavish photographic celebration that captures the fascinating behaviors of land and sea animals in the Galápagos Islands The Galápagos Islands are home to an amazing variety of iconic creatures, from Giant Tortoises, Galápagos Sea Lions, Galápagos Penguins, and Ghost Crabs to Darwin’s finches, the Blue-footed Booby, and Hummingbird Moths. But how precisely do these animals manage to survive on—and in the waters around—their desert-like volcanic islands, where fresh water is always scarce, food is often hard to come by, and finding a good mate is a challenge because animal populations are so small? In this stunning large-format book, Galápagos experts Walter Perez and Michael Weisberg present an unprecedented photographic account of the remarkable survival behaviors of these beautiful and unique animals. With more than 200 detailed, close-up photographs, the book captures Galápagos animals in action as they feed, play, fight, court, mate, build nests, give birth, raise their young, and cooperate and clash with other species. Watch male Marine Iguanas fight over territory and females; see frigatebirds steal food and nesting materials from other birds; witness the courtship dance of a pair of Blue-footed Boobies; go underwater to glimpse a Galápagos Sea Lion pup playing with its mother; and observe a baby Pacific Green Turtle enter the water for the first time. These and dozens of other unforgettable scenes are all vividly captured here—including many moments that even experienced Galápagos observers may never be lucky enough to see in person. Complete with a brief text that provides essential context, this book will be cherished by Galápagos visitors and anyone else who wants to see incredible animals on the move.

Summary : The landscapes of Madagascar have long delighted zoologists, who have discovered, in and among the island’s baobab trees and thickets, a dizzying array of animals, including something approaching one hundred species of lemur. Madagascar’s mammal fauna, for example, is far more diverse, and more endemic, than early explorers and naturalists ever dreamed of. But in the past 2,500 or so years—a period associated with natural climatic shifts and ecological change, as well as partially coinciding with the arrival of the island’s first human settlers—a considerable proportion of Madagascar’s forests have disappeared; and in the wake of this loss, a number of species unique to Madagascar have vanished forever into extinction. In Extinct Madagascar, noted scientists Steven M. Goodman and William L. Jungers explore the recent past of these land animal extinctions. Beginning with an introduction to the geologic and ecological history of Madagascar that provides context for the evolution, diversification, and, in some cases, rapid decline of the Malagasy fauna, Goodman and Jungers then seek to recapture these extinct mammals in their environs. Aided in their quest by artist Velizar Simeonovski’s beautiful and haunting digital paintings—images of both individual species and ecosystem assemblages reproduced here in full color—Goodman and Jungers reconstruct the lives of these lost animals and trace their relationships to those still living. Published in conjunction with an exhibition of Simeonovski’s artwork set to open at the Field Museum, Chicago, in the fall of 2014, Goodman and Jungers’s awe-inspiring book will serve not only as a sobering reminder of the very real threat of extinction, but also as a stunning tribute to Madagascar’s biodiversity and a catalyst for further research and conservation.

Summary : 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.
