"Over the past 55 million years, mammals have returned to the sea many times and in many places. Annalisa Berta leads readers through this parade of transitions, highlighting how marine mammals have met the evolutionary challenge of living an aquatic life in a variety of ways. Return to the Sea weaves ecology, anatomy, and evolution into an ideal entry point for anyone interested in knowing more about one of the most fascinating phenomena in macroevolution."--Nicholas D. Pyenson, National Museum of Natural History, Smithsonian Institution "Berta is to be congratulated. She drew on her vast knowledge of marine mammals and their evolution to write an excellent, readable introduction to the group, including the latest discoveries."--J.G.M. Thewissen, Northeast Ohio Medical University "This wide-ranging and up-to-date survey of marine mammal biology and evolution is a fine introduction to the subject for undergraduates and anyone interested in mammals of the sea."--Daryl P. Domning, Howard University

Squirrels of the World, written by scientists with more than 100 years of collective experience studying these popular mammals, is the first comprehensive examination of all 285 species of squirrels worldwide. The authors reveal virtually every detail of the family Sciuridae, which includes ground squirrels, tree squirrels, flying squirrels, prairie dogs, and chipmunks. Each species—from the familiar gray squirrel of American backyards to the exotic and endangered woolly flying squirrel of Pakistan—is described in a detailed account that includes distinguishing characteristics, ecology, natural history, conservation status, and current threats to its existence. Squirrels of the World includes • stunning color photographs that document rare and unusual squirrels as well as common varieties• evolution, morphology, ecology, and conservation status• colorful range maps marking species distribution• images of the skull of each genus of squirrel• extensive references -- Lawrence Heaney, Curator and Head of the Division of Mammals, The Field Museum (Chicago)

Hans Thewissen, a leading researcher in the field of whale paleontology and anatomy, gives a sweeping first-person account of the discoveries that brought to light the early fossil record of whales. As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science. In his search for an understanding of how modern whales live their lives, Thewissen also journeys to Japan and Alaska to study whales and wild dolphins. He finds answers to his questions about fossils by studying the anatomy of otters and porpoises and examining whale embryos under the microscope. In the book's final chapter, Thewissen argues for approaching whale evolution with the most powerful tools we have and for combining all the fields of science in pursuit of knowledge.

Ranging from crocodiles and penguins to seals and whales, this synthesis explores the function and evolution of sensory systems in animals whose ancestors lived on land. It explores the dramatic transformation of smell, taste, sight, hearing, and balance that occurred as lineages of reptiles, birds, and mammals returned to aquatic environments.

This new edition of Marine Mammals of the World describes and illustrates newly discovered and rarely photographed species, making it the most comprehensive and up-to-date identification guide available. This edition continues to meet the research-focused needs of marine biologists and conservation biologists by providing a tremendous influx of new photos, taking advantage of advances in digital and auto-focusing photography, and the emergence of marine mammal studies and "whalewatching" around the world. The book encompasses cetacean, pinniped, and sirenian species, as well as extinct species, and describes basic biology and taxonomic groupings of marine mammals. Contains superb photographs of every species of marine mammal for accurate identification Authors possess nearly 80 years of collective experience with almost all of the species and distinctive geographic forms described in the guide Provides the most detailed and anatomically accurate illustrations currently available, including more than 750 new illustrations Special emphasis is placed on the identification of species in "problem groups," such as the beaked whales, long-beaked oceanic dolphins, and southern fur seals Includes a detailed list of sources for more information Contains updated taxonomy including four new species
