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,...

Dr. Denise Herzing began her research with a pod of spotted dolphins in the 1980s. Now, almost three decades later, she has forged strong ties with many of these individuals, has witnessed and recorded them feeding, playing, fighting, mating, giving birth and communicating. Dolphin Diaries is an account of Herzing's research and her surprising findings on wild dolphin behavior, interaction, and communication. Readers will be drawn into the highs and lows--the births and deaths, the discovery of unique and personalized behaviors, the threats dolphins face from environmental changes,...

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...

This book explores afresh the long-standing interest, and emphasis on, the special' capacities of primates. Some of the recent discoveries of the higher cognitive abilities of other mammals and also birds challenge the concept that primates are special and even the view that the cognitive ability of apes is more advanced than that of nonprimate mammals and birds. It is therefore timely to ask whether primates are, in fact, special and to do so from a broad range of perspectives. Divided into five sections this book deals with topics about higher cognition and how it is manifested in...

Linking the evidence of the past with that of the present,...

The function of vertebrate hearing is served by a surprising variety of sensory structures in the different groups of fish, amphibians, reptiles, birds, and mammals. This book discusses the origin, specialization, and functional properties of sensory hair cells, beginning with environmental constraints on acoustic systems and addressing in detail the evolutionary history behind modern structure and function in the vertebrate ear. Taking a comparative approach, chapters are devoted to each of the vertebrate groups, outlining the transition to land existence and the further parallel and...

Delve into amazingly intimate wolf photography by Jim and Jamie Dutcher, a couple who spent many years living with a pack of wolves at the edge of Idaho's Sawtooth Wilderness, observing their complex social hierarchy. Here is the alpha pair, leaders of the pack, often the only couple that mate. Here are the pups, born with eyes shut in the spring, tousled by their mother through the first six weeks of...
