"Not much has been written about the women who have helped define and develop the field of vertebrate paleontology over the last 100 years. The paleontologist coauthors of this book aim to remedy this situation by offering an international collection of compelling stories about the discovery, collection, and study of fossil vertebrates done by women paleontologists"--

Berta and Sumich have succeeded yet again in creating superior marine reading! This book is a succinct yet comprehensive text devoted to the systematics, evolution, morphology, ecology, physiology, and behavior of marine mammals. The first edition, considered the leading text in the field, is required reading for all marine biologists concerned with marine mammals. Revisions include updates of citations, expansion of nearly every chapter and full color photographs. This title continues the tradition by fully expanding and updating nearly all chapters.* Comprehensive, up-to-date coverag

"Return to the Sea portrays the life and evolutionary times of marine mammals--from giant whales and sea cows that originated 55 million years ago to the deep diving elephant seals and clam-eating walruses of modern times. This fascinating account of the origin of various marine mammal lineages, some extinct, others extant but threatened, is for the non-specialist. Set against a backdrop of geologic time, changing climates, and changing geography, evolution is the unifying principle that helps us to understand the present day diversity of marine mammals and their responses to environmental challenges. Annalisa Berta explains current controversies and explores patterns of change taking place today, such as shifting food webs and predator-prey relationships, habitat degradation, global warming, and the effects of humans on marine mammal communities"-- "This book portrays the life and evolutionary times of marine mammals, from giant whales and sea cows that originated 55 million years ago and walked on land, to deep-diving elephant seals and clam-eating walruses of modern times. Some animals like the hippo-sized herbivorous desmostylians and aquatic sloths were evolutionary experiments that did not survive. This fascinating account of the origin of various marine mammal lineages written for the non-specialist is set against a backdrop of geologic time, changing climates, and geography. The thread of evolution runs through the book and helps us to understand the today's diversity of marine mammals and marine-mammal responses to environmental challenges. The story of the evolution of these fascinating animals, their lives and habits, offers a valuable perspective and in some cases lessons for the future. Berta also informs readers about current controversies in the field of marine mammalogy, presenting a balanced view based on careful evaluation and interpretation of the evidence. She explores patterns of change taking place today such as changing food webs and predator-prey relationships, habitat degradation, global warming, and the effects of humans on marine-mammal communities. The future of marine mammals depends on each of us, scientists as well as the informed public, working together to avoid crises before they develop or appropriately managing those that do arise"--

Marine mammals have long captured the attention of humans. Ancient peoples etched seals and dolphins on the walls of Paleolithic caves; today, engineers develop microprocessors to track these denizens of the deep. This groundbreaking book from highly respected marine mammal paleontologist Annalisa Berta delves into the story of the extraordinary adaptations that gave the world these amazing animals. The Rise of Marine Mammals reveals remarkable fossil record discoveries that shed light on the origins, relationships, and diversification of marine mammals. Focusing on evolution and paleobiology, Berta provides an overview of marine mammal species diversity, enhanced with gorgeous life restorations by Carl Buell, Robert Boessenecker, William Stout, and Ray Troll and extensive line drawings by graphics editor James L. Sumich. The book also considers ongoing conservation challenges, demonstrating how the fossil record of adaptation in response to past environmental shifts may illuminate the way that marine mammals respond to global climate change. This invaluable evolutionary framework is essential for helping us understand how best to protect and conserve today's polar bears, whales, dolphins, seals, and fellow warm-blooded ocean dwellers. The Rise of Marine Mammals also describes exciting breakthroughs that rely on new techniques of study, including 3-D imaging, and molecular, finite element, and morphometric analyses, which have enhanced scientists' understanding of everything from the anatomy of fetal whales to the genes behind limb loss in cetaceans. Mammalogists, paleontologists, and marine scientists will find Berta's insights absorbing, while developmental and molecular biologists, geneticists, and ecologists exploring integrative research approaches will benefit from her fresh perspective.
