Download or read book Evolution and Environment in Tropical America written by Jeremy B. C. Jackson and published by University of Chicago Press. This book was released on 1996-12-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: How were the tropical Americas formed? This ambitious volume draws on extensive, multidisciplinary research to develop new views of the geological formation of the isthmus linking North and South America and of the major environmental changes that reshaped the Neotropics to create its present-day marine and terrestrial ecosystems. Recent discoveries show that dramatic changes in climate and ocean circulation can occur very quickly, and that ecological communities respond just as rapidly. Abrupt changes in the composition of fossil assemblages, formerly dismissed as artifacts of a poor fossil record, now are seen as accurate records of swift changes in the composition of ocean communities. The twenty-four contributors use current work in paleontology, geology, oceanography, anthropology, ecology, and evolution to paint this challenging portrait of rapid environmental and evolutionary change. Their conclusions argue for a revision of existing interpretations of the fossil record and the processes—including invading Eurasian peoples—that have produced it.
Download or read book Understanding Fossils written by Peter Doyle and published by John Wiley & Sons. This book was released on 2014-08-15 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first introductory palaeontology text which demonstrates the importance of selected fossil groups in geological and biological studies, particularly in understanding evolutionary patterns, palaeoenvironmental analysis, and stratigraphy. Part one explores several key concepts, such as the processes of fossil preservation, the determination of evolutionary patterns, and use of fossils and statigraphical tools. Part two introduces the main fossil groups of value in these applied fields. Part three concentrates on the examination of important case histories which demonstrate the use of fossils in diverse practical examples. Evolutionary studies, palaeoenvironmental analysis, and stratigraphical applications are documented using up-to-date examples supported by overviews of the principles.
Download or read book After the Dinosaurs written by Donald R. Prothero and published by Indiana University Press. This book was released on 2006-07-13 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating study of the thousands of new animal species that walked in the footsteps of the dinosaurs—and the climate changes that brought them forth. The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth’s history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures―including our own ancestors. Their story is part of a larger story of new life emerging from the greenhouse conditions of the Mesozoic, warming up dramatically about 55 million years ago, and then cooling rapidly so that 33 million years ago the glacial ice returned. The earth’s vegetation went through equally dramatic changes, from tropical jungles in Montana and forests at the poles. Life in the sea underwent striking evolution reflecting global climate change, including the emergence of such creatures as giant sharks, seals, sea lions, dolphins, and whales. Engaging and insightful, After the Dinosaurs is a book for everyone who has an abiding fascination with the remarkable life of the past.

Download or read book The Preservation of Species written by Bryan G. Norton and published by Princeton University Press. This book was released on 2014-07-14 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: For all persons seriously concerned about the destruction of natural environments in the contemporary world, this book presents a comprehensive rationale for preserving wild species and ecosystems. Bryan G. Norton appeals most centrally to "transformative value," the power of human contacts with wild species to transform and uplift the human spirit. Until now species preservationists have found a theoretical basis for their policies in the "demand" value of wild species for fulfilling certain narrowly defined human needs or in controversial and badly understood proposals about the "intrinsic" values of species. This work examines such rationales and diverges from them by pointing to new sources of value for wild species: they have worth because they can transform human values. Because of the central role of biological diversity in environmental concerns, the book also provides a fresh perspective on environmental ethics more generally. Why Preserve Natural Variety? is sponsored by the Center for Philosophy and Public Policy at the University of Maryland, as was The Preservation of Species: The Value of Biological Diversity, which was edited by Professor Norton. Originally published in 1986. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
