The Age of Mammals
Author: Donald R. Prothero
Publisher: Indiana University Press
View: 5485A 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.

View: 9554Few aspects of American military history have been as vigorously debated as Harry Truman's decision to use atomic bombs against Japan. In this carefully crafted volume, Michael Kort describes the wartime circumstances and thinking that form the context for the decision to use these weapons, surveys the major debates related to that decision, and provides a comprehensive collection of key primary source documents that illuminate the behavior of the United States and Japan during the closing days of World War II. Kort opens with a summary of the debate over Hiroshima as it has evolved since 1945. He then provides a historical overview of thye events in question, beginning with the decision and program to build the atomic bomb. Detailing the sequence of events leading to Japan's surrender, he revisits the decisive battles of the Pacific War and the motivations of American and Japanese leaders. Finally, Kort examines ten key issues in the discussion of Hiroshima and guides readers to relevant primary source documents, scholarly books, and articles.

View: 1456This is a New York Public Library Outstanding Reference Book of 1998. While the inhabitants of the lost world have long held sway over our imaginations, in recent years dinosaur science has experienced an explosive growth. More books on dinosaurs have been published in the past decade than in all the previous 150 years since Richard Owen named these 'fearfully great lizards' (correctly, 'reptiles'), and dinosaur research continues to make headlines. Reporting the latest discoveries and research, this book is an exuberant celebration of dinosaurs and of our ongoing fascination with them. Here, in one volume, is the single, most-authoritative account of dinosaur paleontology for the general reader. So rapidly has the field expanded that no individual can hope to master all the aspects of dinosaur paleontology. For this book, the editors have brought together forty-six experts in subjects ranging from functional morphology and paleobiology to biogeography and systematics to present a thorough survey of the dinosaurs from the earliest discoveries through the contemporary controversies over their extinction. Where contention exists, as over the question of whether dinosaurs were warm-blooded or cold-blooded, the editors have let the experts agree to disagree. Throughout technical jargon is kept to a minimum, and there is also a glossary of less familiar terms. Readers will find a wealth of information on the study and classification of dinosaurs, on each of the dinosaur groups, and on dinosaur biology and evolution. Not the least among these riches are the more than 350 illustrations (Including 16 pages of color plates), many prepared especially for this volume. The volume concludes with a survey of dinosaurs in the media and a chronology of the history of dinosaur science. This is the single most authoritative account of dinosaur paleontology for the general public, all in one volume. Sumptuously illustrated, with up-to-the-minute information, it features: more than 350 illustrations, including 16 pages in full color; each chapter written by an expert in dinosaur studies; includes the latest dinosaur discoveries; new information on the warm-blooded/cold-blooded debate; new insights on the possibility of isolating dinosaur DNA; what dinosaurs ate and how we know about it; dinosaurs in the media; a time-line of the history of dinosaur science; and much, much more!

Seven Ages of the Cosmos
Author: Eric J. Chaisson
Publisher: Columbia University Press
View: 9988How did everything around us-the air, the land, the sea, and the stars-originate? What is the source of order, form, and structure characterizing all material things? These are just some of the grand scientific questions Eric J. Chaisson, author of the classic work Cosmic Dawn, explores in his enthralling and illuminating history of the universe. Explaining new discoveries and a range of cutting-edge ideas and theories, Chaisson provides a creative and coherent synthesis of current scientific thinking on the universe's beginnings. He takes us on a tour of the seven ages of the cosmos, from the formless era of radiation through the origins of human culture. Along the way he examines the development of the most microscopic and the most immense aspects of our universe and the complex ways in which they interact. Drawing on recent breakthroughs in astrophysics and biochemistry, Chaisson discusses the contemporary scientific view that all objects-from quarks and quasars to microbes and the human mind-are interrelated. Researchers in all the natural sciences are beginning to identify an underlying pattern penetrating the fabric of existence-a sweepingly encompassing view of the formation, structure, and function of all objects in our multitudinous universe. Moreover, as Chaisson demonstrates, by deciphering the scenario of cosmic evolution, scientists can also determine how living organisms managed to inhabit the land, generate language, and create culture. Epic of Evolution offers a stunning view of how various changes, operating across almost incomprehensible domains of space and nearly inconceivable stretches of time and through the evolutionary combination of necessity and chance, have given rise to our galaxy, our star, our planet, and ourselves.

The Growing Threat Of Species Invasions
Author: Yvonne Baskin
Publisher: Island Press
View: 9388The human love of novelty and desire to make one place look like another, coupled with massive increases in global trade and transport, are creating a growing economic and ecological threat. The same forces that are rapidly "McDonaldizing" the world's diverse cultures are also driving us toward an era of monotonous, weedy, and uniformly impoverished landscapes. Unique plant and animal communities are slowly succumbing to the world's "rats and rubbervines" -- animals like zebra mussels and feral pigs, and plants like kudzu and water hyacinth -- that, once moved into new territory, can disrupt human enterprise and well-being as well as native habitats and biodiversity. From songbird-eating snakes in Guam to cheatgrass in the Great Plains, "invasives" are wreaking havoc around the world. In A Plague of Rats and Rubbervines, widely published science writer Yvonne Baskin draws on extensive research to provide an engaging and authoritative overview of the problem of harmful invasive alien species. She takes the reader on a worldwide tour of grasslands, gardens, waterways, and forests, describing the troubles caused by exotic organisms that run amok in new settings and examining how commerce and travel on an increasingly connected planet are exacerbating this oldest of human-created problems. She offers examples of potential solutions and profiles dedicated individuals worldwide who are working tirelessly to protect the places and creatures they love. While our attention is quick to focus on purposeful attempts to disrupt our lives and economies by releasing harmful biological agents, we often ignore equally serious but much more insidious threats, those that we inadvertently cause by our own seemingly harmless actions. A Plague of Rats and Rubbervines takes a compelling look at this underappreciated problem and sets forth positive suggestions for what we as consumers, gardeners, travelers, nurserymen, fishermen, pet owners, business people -- indeed all of us who by our very local choices drive global commerce -- can do to help.

Cause and Human Consequences
Author: Jim Snook
Publisher: Algora Publishing
View: 488Global warming seen from the other side: by the end of the last ice age, the earth had lost most of its large animal species and most of its humans. In a novel approach the author argues that the main cause of this catastrophic extinction was a drastic reduction in atmospheric carbon dioxide, due to the long period of cold, and he backs up his theory with scientific explanations given in clear language for the general reader. The author explores the causes of Earth s cyclical temperature changes and shows how those temperature shifts touch off a chain of events in the atmosphere, in the oceans and on land. Cold temperature was the trigger; and the resultant reduction in carbon dioxide, he argues, was the bullet that killed off so many species. The re-warming released more carbon dioxide into the atmosphere and fueled a resurgence which we are still enjoying. In addition, the author describes the human responses to increases in atmospheric carbon dioxide after the last ice age and in the last 150 years. Near the end of the last ice age, atmospheric carbon dioxide was about half of what it is today. Due to the lack of carbon dioxide, most of the vegetation disappeared from the middle and high latitudes. Without plants to eat, many large animals became extinct; North America lost three-fourths of its large animals including the woolly mammoth, mastodon, and saber tooth cat. Humans, too, had little to eat in these areas and their population declined dramatically. The book then explains how and why atmospheric carbon dioxide increased by about 50% after the last ice age ended, encouraging a population explosion among plants, animals and humans, all of which then migrated into many previously barren areas. More recently, the 28% increase in atmospheric carbon dioxide in the last 150 years has caused a six-fold increase in the human population. Changes in the next 300 years will reverse some of the current trends. There have been some books on the causes of extinction over the last forty years, but all looked at other causes and none examined the role of low atmospheric carbon dioxide. This book has value for anyone interested in the ice age extinction; glaciers; the glacial cycle; the atmosphere and oceans; the past and future of plants, animals, and humans. It provides long-term information on atmospheric carbon dioxide, global warming and cooling.

Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen.

Ancient Sea Life of North America
Author: John Foster
Publisher: Indiana University Press
View: 8882This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth’s history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet’s long history.
The Future of Evolution in the Aftermath of Man
Author: Michael Tennesen
Publisher: Simon and Schuster
View: 1054“Simultaneously sobering and exhilarating, Michael Tennesen’s wide-ranging survey of disasters highlights both life’s fragility and its metamorphosing persistence” (Booklist) and describes what life on earth could look like after the next mass extinction. A growing number of scientists agree we are headed toward a mass extinction, perhaps in as little as 300 years. Already there have been five mass extinctions in the last 600 million years, including the Cretaceous Extinction, during which an asteroid knocked out the dinosaurs. Though these events were initially destructive, they were also prime movers of evolutionary change in nature. And we can see some of the warning signs of another extinction event coming, as our oceans lose both fish and oxygen, and our lands lose both predators and prey. In The Next Species, Michael Tennesen questions what life might be like after it happens. In thoughtful, provocative ways, Tennesen discusses the future of nature and whether humans will make it through the bottleneck of extinction. Could life suddenly get very big as it did before the arrival of humans? Could the conquest of Mars lead to another form of human? Could we upload our minds into a computer and live in a virtual reality? How would we recognize the next humans? Are they with us now? Tennesen delves into the history of the planet and travels to rainforests, canyons, craters, and caves all over the world to explore the potential winners and losers of the next era of evolution. His predictions, based on reports and interviews with top scientists, have vital implications for life on earth today. The Next Species is “an engrossing history of life, the dismal changes wrought by man, and a forecast of life after the sixth mass extinction” (Kirkus Reviews).
An Introduction to Paleobiology

Publisher: Columbia University Press
View: 2130One of the leading textbooks in its field, Bringing Fossils to Life applies paleobiological principles to the fossil record while detailing the evolutionary history of major plant and animal phyla. It incorporates current research from biology, ecology, and population genetics, bridging the gap between purely theoretical paleobiological textbooks and those that describe only invertebrate paleobiology and that emphasize cataloguing live organisms instead of dead objects. For this third edition Donald R. Prothero has revised the art and research throughout, expanding the coverage of invertebrates and adding a discussion of new methodologies and a chapter on the origin and early evolution of life.
