Download or read book North American Watersnakes written by J. Whitfield Gibbons and published by University of Oklahoma Press. This book was released on 2004 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many people fear snakes, and watersnakes in particular have one of the worst reputations of any snake found in North America. Some species are commonly mistaken for venomous cottonmouths, and a few may eat popular game fishes. Unfortunately, few people realize the important roles many watersnakes play in natural ecosystems and, consequently, they are still persecuted in many regions today. Seeking to overcome common misperceptions, J. Whitfield Gibbons and Michael E. Dorcas have compiled North American Watersnakes, the first comprehensive study of all fourteen species of watersnakes found in the United States, Canada, Mexico, and Cuba. Individual species accounts explore all aspects of the natural history of watersnakes in North America, including their behavior, physiology, life history, ecology, and conservation. Almost 100 color photographs accompany the text, illustrating all 14 species and nearly all subspecies. Supplementing the species accounts are detailed color maps depicting each species distribution and stunning black-and-white drawings by Peri Mason. Easy-to-use keys help readers to identify specimens at hand.
Download or read book Fossil Snakes of North America written by J. Alan Holman and published by Indiana University Press. This book was released on 2000 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This volume includes detailed accounts of the morphology and distribution of the fossil snakes of North America and also remarks on their evolutionary, zoogeographic, and paleoecological patterns. The heart of the book consists of detailed systematic accounts of the known fossil snakes of North America and their localities. Extinct fossil taxa are discussed and illustrated, and many are re-described on the basis of new information. The book provides illustrations of diagnostic vertebrae and criteria for the identification of presently living fossil snake taxa as well as descriptions of the modern characteristics and ranges of these species." "Color photographs in the 16-page insert present a catalog of representative living snake species." --Book Jacket.

Download or read book The White River Badlands written by Rachel C. Benton and published by Indiana University Press. This book was released on 2015-05-25 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide to the South Dakota region that houses the world’s richest fossil beds does “an excellent job of presenting the current state of knowledge” (Choice). The forbidding Big Badlands in Western South Dakota contain the richest fossil beds in the world. Even today these rocks continue to yield new specimens brought to light by snowmelt and rain washing away soft rock deposited on a floodplain long ago. The quality and quantity of the fossils are superb: most of the species to be found there are known from hundreds of specimens. The fossils in the White River Group (and similar deposits in the American west) preserve the entire late Eocene through the middle Oligocene, roughly 35-30 million years ago and more than thirty million years after non-avian dinosaurs became extinct. The fossils provide a detailed record of a period of abrupt global cooling and what happened to creatures who lived through it. This book is a comprehensive reference to the sediments and fossils of the Big Badlands, and also touches on National Park Service management policies that help protect such significant fossils. Includes photos and illustrations “A worthy successor to the work of O’Harra.” —Journal of Vertebrate Paleontology
Download or read book Paleobiology of the Williamsburg Formation Black Mingo Group Paleocene of South Carolina U S A written by Albert E. Sanders and published by American Philosophical Society. This book was released on 1998 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a print on demand publication. The excavation of an immense pit near the Santee River in South Carolina has produced the first Paleocene vertebrate fauna from the South Atlantic coast of the U.S., as well as a rich flora that provides extensive knowledge of the paleoenvironmental setting in which those animals flourished nearly 60 million years ago. The excavation penetrated the Late Paleocene Williamsburg Formation & yielded many specimens collected from the spoil piles, among which were the first Paleocene mammal remains from the east coast of North America. Here, eight paleobiologists interpret the discoveries systematically & compare them with Paleocene floras & faunas from elsewhere in North America & around the globe. Auhors include: Bruce Erickson (crocodilians & a snake); Robert Weems (bony fishes); Weems & Laurel Bybell (geological setting); Lucy Edwards (dinoflagellates); Robert Melchior (pollen, spores, fossil wood, & amber); Robert Purdy (sharks & rays); Howard Hutchison & Robert Weems (turtles); Robert Schoch (mammals), Glenn Sawyer (coprolites); & Erickson & Melchior (trace fossils). "One of the most significant contributions to our knowledge of early Tertiary times in this region."
Download or read book Geographic Variation in Behavior written by Susan Adlai Foster and published by Oxford University Press, USA. This book was released on 1999 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of animal behavior often assume that all members of a species exhibit the same behavior. Geographic Variation in Behavior shows that, on the contrary, there is substantional variation within species across a wide range of taxa. Including work from pioneers in the field, this volume provides a balanced overview of research on behavioral characteristics that vary geographically. The authors explore the mechanisms by which behavioral differences evolve and examine related methodological issues. Taken together, the work collected here demonstrates that genetically based geographic variation may be far more widespread than previously suspected. The book also shows how variation in behavior can illuminate both behavioral evolution and general evolutionary patterns. Unique among books on behavior in its emphasis on geographic variation, this volume is a valuable new resource for students and researchers in animal behavior and evolutionary biology.

Download or read book Evolutionary Paleobiology of Behavior and Coevolution written by A.J. Boucot and published by Elsevier. This book was released on 2013-10-22 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the culmination of many years of research by a scientist renowned for his work in this field. It contains a compilation of the data dealing with the known stratigraphic ranges of varied behaviors, chiefly animal with a few plant and fungal, and coevolved relations. A significant part of the data consists of ``frozen behavior'', i.e. those in which an organism has been preserved while actually ``doing'' something, as contrasted with the interpretations of behavior of an organism deduced from functional morphology, important as the latter may be. The conclusions drawn from this compilation suggest that both behaviors and coevolved relations appear infrequently, following which there is relative fixity of the relation, i.e., two rates of evolution, very rapid and essentially zero. This conclusion complies well with the author's prior conclusion that community evolution followed the same rate pattern. In fact, communities are regarded here, as in large part, expressions of both behavior and coevolved relations, rather than as random aggregates controlled almost wholly by varied, unrelated physical parameters tracked by organisms, i.e., the concept that communities have no biologic reality, being merely statistical abstractions. The book is illustrated throughout with more than 400 photographs and drawings. It will be of interest to ethologists, evolutionists, parasitologists, paleontologists, and palaeobiologists at research and post-graduate levels.
Download or read book The Great American Biotic Interchange written by Francis G. Stehli and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two rather different elements combine to explain the origin of this volume: one scientific and one personal. The broader of the two is the scientific basis-the time for such a volume had arrived. Geology had made remarkable progress toward an understanding of the phys ical history of the Caribbean Basin for the last 100 million years or so. On the biological side, many new discoveries had elucidated the distributional history of terrestrial orga nisms in and between the two Americas. Geological and biological data had been combined to yield the timing of important events with unprecedented resolution. Clearly, when each of two broad disciplines is making notable advances and when each provides new insights for the other, the rewards of cross-disciplinary contacts increase exponentially. The present volume represents an attempt to bring together a group of geologists, paleontologists and biologists capable of exploiting this opportunity through presentation of an interdisciplinary synthesis of evidence and hypothesis concerning interamerican connections during the Cretaceous and Cenozoic. Advances in plate tectonics form the basis for a modern synthesis and, in the broadest terms, dictate the framework within which the past and present distributions of organisms must be interpreted. Any scientific dis cipline must seek tests of its conclusions from data outside of its own confines.
