Book Description
Treeshrews suffer from chronic mistaken identity: they are not shrews, and most are not found in trees. These squirrel-sized, brownish mammals with large, dark, lashless eyes were at one time thought to be primates. Even though most scientists now believe them to belong in their own mammalian order, Scandentia, they still are thought to resemble some of the earliest mammals, which lived alongside the dinosaurs. This book describes the results of the first comparative study of the ecology of treeshrews in the wild. Noted tropical mammalogist Louise H. Emmons conducted this pathbreaking study in the rainforests of Borneo as she tracked and observed six species of treeshrews. Emmons meticulously describes their habitat, diet, nesting habits, home range, activity patterns, social behavior, and many other facets of their lives. She also discusses a particularly interesting aspect of treeshrews: their enigmatic parental care system, which is unique among mammals.

Book Description
Tree shrews are small-bodied, scansorial, squirrel-like mammals that occupy a wide range of arboreal, semi-arboreal, and forest floor niches in Southeast Asia and adjacent islands. Comparative aspects of tree shrew biology have been the subject of extensive investigations during the past two decades. These studies were initiated in part because of the widely accepted belief that tupaiids are primitive primates, and, as such, might provide valuable insight into the evolutionary origin of complex patterns of primate behavior, locomotion, neurobiology, and reproduction. During the same period, there has been a renewed interest in the methodology of phylogenetic reconstruction and in the use of data from a variety of biological disciplines to test or formulate hypotheses of evolutionary relationships. In particular, interest in the com parative and systematic biology of mammals has focused on analysis of phy logenetic relationships among Primates and a search for their closest relatives. Assessment of the possible primate affinities of tree shrews has comprised an important part of these studies, and a considerable amount of dental, cranio skeletal, neuroanatomical, reproductive, developmental, and molecular evi dence has been marshalled to either corroborate or refute hypotheses of a special tupaiid-primate relationship. These contrasting viewpoints have re sulted from differing interpretations of the basic data, as well as alternative approaches to the evolutionary analysis of data.

Book Description
The ultimate illustrated guide to the lost world of prehistoric mammals After the mass extinction of the dinosaurs 65 million years ago, mammals became the dominant terrestrial life form on our planet. Roaming the earth were spectacular beasts such as saber-toothed cats, giant mastodonts, immense ground sloths, and gigantic giraffe-like rhinoceroses. Here is the ultimate illustrated field guide to the lost world of these weird and wonderful prehistoric creatures. A woolly mammoth probably won't come thundering through your vegetable garden any time soon. But if one did, this would be the book to keep on your windowsill next to the binoculars. It covers all the main groups of fossil mammals, discussing taxonomy and evolutionary history, and providing concise accounts of the better-known genera and species as well as an up-to-date family tree for each group. No other book presents such a wealth of new information about these animals—what they looked like, how they behaved, and how they were interrelated. In addition, this unique guide is stunningly illustrated throughout with full-color reconstructions of these beasts—many never before depicted—along with photographs of amazing fossils from around the world. Provides an up-to-date guidebook to hundreds of extinct species, from saber-toothed cats to giant mammoths Features a wealth of color illustrations, including new reconstructions of many animals never before depicted Demonstrates evolution in action—such as how whales evolved from hoofed mammals and how giraffes evolved from creatures with short necks Explains how mass extinctions and climate change affected mammals, including why some mammals grew so huge

Book Description
Myopia and the Control of Eye Growth Chairman: J. Wallman 1990 Myopia is the most common disorder of the eye, affecting 80% of the population in some countries. Its basis remains uncertain; recent developments of animal models of myopia have permitted experimental tests of hypotheses about possible aetiological causes. This symposium covers the normal growth of the eye and the involvement of metabolism, accommodation and other factors in normal and abnormal growth. The deficiencies that lead to myopia and other refractive disorders are discussed. Aspects of retinal anatomy and physiology relevant to the understanding of the biological factors limiting visual resolution are described. The effects of neurotransmitters and neurotoxins on eye growth reveal information about the nature of normal and experimentally manipulated eye growth and development. The multiplicity of theories about the aetiology of myopia has led to numerous therapeutic approaches; the effectiveness of such therapies is debated. Animal models of myopia have demonstrated the importance of patterned visual input to the developing eye and the ability of the eye to recover if the constraint that caused the myopia is removed early enough. These findings are significant for the detection and correction of myopia in newborn human infants. Other Ciba Foundation Symposia: No 126 Selective neuronal death Chairman: H.

Book Description
A completely revised and updated edition of the leading mammalogy textbook, featuring color photographs throughout and a new streamlined structure for enhanced use in courses. There are more than 6,400 species in the class Mammalia, including the blue whale—the largest animal that has ever lived—and the pygmy shrew, which weighs little more than a dime. Such diversity among mammals has allowed them to play critical roles in every ecosystem, whether marine, freshwater, alpine, tundra, forest, or desert. Reflecting the expertise and perspective of five leading mammalogists, the fifth edition of Mammalogy: Adaptation, Diversity, Ecology significantly updates taxonomy, adds a new introductory chapter on the science of mammalogy, and highlights several recently described species. To enhance its appeal to students, textual material has been reduced, consolidated, and streamlined without sacrificing breadth or depth of coverage. The fifth edition includes • for the first time, stunning color photographs throughout • chapters rearranged and grouped to best reflect phylogenetic relationships, with updated numbers of genera and species for each family • updated mammalian structural and functional adaptations, as well as ordinal fossil histories • recent advances in mammalian phylogeny, biogeography, social behavior, and ecology, with 12 new or revised cladograms reflecting current research findings • new breakout boxes on novel or unique aspects of mammals • new work on female post-copulatory mate choice, cooperative behaviors, group defense, and the role of the vomeronasal system • discussions of the current implications of climate change and other anthropogenic factors for mammals Maintaining the accessible, readable style for which Feldhamer and his coauthors are well known, this new edition of Mammalogy is the authoritative textbook on this amazingly diverse class of vertebrates.

Book Description
Treeshrews are misleadingly named, as they are not shrews and do not live in trees. The authors tracked and studied six species of shrew in the Bornean rainforest, and this text descibes their habitat, nesting behaviour, and other facets of their lives.
