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

Giant Galápagos tortoises have roamed the Galápagos Islands for thousands of years, but these creatures almost disappeared from their tropical habitat. Giant Galápagos Tortoise describes the world's largest tortoise, how sailors and invasive species caused its population to dwindle, and how habitat preservation and captive breeding have helped save the species. Easy-to-read text, vivid images, and helpful back matter give readers a clear look at this subject. Features include a table of contents, infographics, a glossary, additional resources, and an index. Aligned to Common Core Standards and correlated to state standards. Core Library is an imprint of Abdo Publishing, a division of ABDO.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1914 edition. Excerpt: ...condition in the type of T. becki is an individual variation, since it is the fourth vertebra which is biconvex in my series of seven specimens from Bank's Bay. The condition doubtless is anomalous also in the Charles Island specimen. The differences in proportion of the bones of the limbs and neck correspond with the relative length of these parts in the various races, the number of bones being the same in all. They are proportionally shorter in the dome-shaped races, and longer in those in which the carapace is elevated and compressed anteriorly. These differences are shown in the measurements of the limbs and neck given with the description of each race or species. Certain differences in the skulls of the tortoises of the various races have been pointed out by Dr. Gunther. I believe that the differences he has indicated are all merely individual variations. In a series of 24 skulls from Vilamil, Albemarle, I find all of the variations which Dr. Gunther mentions; and upon careful comparison of this series with one skull from Hood Island (No. 8125), one from Indefatigable (No. 8381), one from James (No. 8105), three from Duncan (Nos. 8378, 8379, and 8380), four from Chatham (Nos. 8127, 8128, 8130, and 8131), and one from Iguana Cove (No. 8179), I can find no constant differences in the skulls of the various races. In the skulls from Vilamil, the frontal region may be flat or somewhat convex. The occipital spine may be short or long, not reaching the posterior borders of the mastoid processes or projecting far behind them, and may or may not rise much above the level of the skull. There is much variation in the shape of the tympanic case and cavity. The fossa in front of the occipital condyle may be deep or very shallow. The...

The extended continental South American turtle record (Norian to Lujanian) allows us to follow the evolution of this reptile clade from its origins. Several significant stem turtle taxa such as: Palaeochersis talampayensis and Condorchelys antiqua provide information on the first steps of turtle evolution. Others such as: Chubutemys copelloi or Patagoniaemys gasparinae provide clues to the origin of the bizarre horned tortoises of the clade Meiolaniidae. The panpleurodiran species such as Notoemys laticentralis or Notoemys zapatocaensis shed light on the origin of modern pleurodiran turtles. This book explores aquatic and terrestrial cryptodiran turtles, South Gondwana pleurodiran turtles, North Gondwana pleurodiran turtles; Meiolaniforms and early differentiation of Mesozoic turtles.
