Book Description
The fascinating lives and puzzling demise of some of the largest animals on earth. Until a few thousand years ago, creatures that could have been from a sci-fi thriller—including gorilla-sized lemurs, 500-pound birds, and crocodiles that weighed a ton or more—roamed the earth. These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone. What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses. Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.

Book Description
Ecological competition began as slow arms races. Predators evolved to hunt. Prey evolved to defend themselves. Each improvement was small, barely shifting the odds of survival. Nature remained in equilibrium. Until the dawn of humanity. When our ancestors developed the unique ability to think up new devices and behaviors, humanity became able to overcome nature's defenses far more quickly than natural selection could respond. Humankind spread out of Africa, wiping out most of the megafauna in its path-mammoths, sabertooth cats, elephant-sized sloths, and a great many other species. Today, this formidable, inventive genius of our species-now grown to overwhelming and all-conquering proportions-is threatening to make the earth unlivable, even for ourselves. The only weapon available to us to counter this threat is, ironically, the same one that unleashed our destructiveness in the first place: the analytical and creative power of the human brain.

Book Description
“An enjoyable read that provides a substantial amount of detail on the biology, ecology, and distribution of these fantastic animals . . . Highly recommended.” —Choice More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans. It places these giants within the context of the other mammals then alive, describing their paleobiology—how they walked; how much they weighed; their diets, behavior, biomechanics; and the interactions among them and with their environment. It also tells the stories of the scientists who contributed to our discovery and knowledge of these transcendent creatures and the environment they inhabited. The episode known as the Great American Biotic Interchange, perhaps the most important of all natural history “experiments,” is also an important theme of the book, tracing the biotic events of both North and South America that led to the fauna and the ecosystems discussed in this book. “Collectively, this book brings attention to the discovery and natural history of ancient beasts in South America while providing a broader temporal and geographic background that allows readers to understand their evolution and potential immigration to South America.” —Quarterly Review of Biology “An excellent volume . . . This book is likely to facilitate progress in the understanding of fossil mammals from the Americas.” —Priscum

Book Description
The volume contains summaries of facts, theories, and unsolved problems pertaining to the unexplained extinction of dozens of genera of mostly large terrestrial mammals, which occurred ca. 13,000 calendar years ago in North America and about 1,000 years later in South America. Another equally mysterious wave of extinctions affected large Caribbean islands around 5,000 years ago. The coupling of these extinctions with the earliest appearance of human beings has led to the suggestion that foraging humans are to blame, although major climatic shifts were also taking place in the Americas during some of the extinctions. The last published volume with similar (but not identical) themes -- Extinctions in Near Time -- appeared in 1999; since then a great deal of innovative, exciting new research has been done but has not yet been compiled and summarized. Different chapters in this volume provide in-depth resumés of the chronology of the extinctions in North and South America, the possible insights into animal ecology provided by studies of stable isotopes and anatomical/physiological characteristics such as growth increments in mammoth and mastodont tusks, the clues from taphonomic research about large-mammal biology, the applications of dating methods to the extinctions debate, and archeological controversies concerning human hunting of large mammals.

Book Description
Animals and Human Society provides a solid, scientific, research-based background to advance understanding of how animals impact humans. Animals have had profound effects on people from the earliest times, ranging from zoonotic diseases, to the global impact of livestock, poultry and fish production, to the influences of human-associated animals on the environment (on extinctions, air and water pollution, greenhouse gases, etc.), to the importance of animals in human evolution and hunter -gatherer communities.As a resource for both science and non-science, Animals and Human Society can be used as a text for courses in Animals and Human Society or Animal Science, or as supplemental material for Introduction to Animal Science. It offers foundational background to those who may have little background in animal agriculture and have focused interest on companion animals and horses. The work introduces livestock production (including poultry and aquaculture) but also includes coverage of companion and lab animals. In addition, animal behavior and animal perception are covered.Animals and Human Society is likewise an excellent resource for researchers, academics, or students newly entering a related field or coming from another discipline and needing foundational information, as well as interested laypersons looking to augment their knowledge on the many impacts of animals in human society. - Features research-based and pedagogically sound content, with learning goals and textboxes to provide key information - Challenges readers to consider issues based on facts rather than polemics - Poses ethical questions and raises overall societal impacts - Balances traditional animal science with companion animals, animal biology, zoonotic diseases, animal products, environmental impacts and all aspects of human/animal interaction

Book Description
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.
