The 762 full-color identification photographs show the mushrooms as they appear in natural habitats. Organized visually, the book groups all mushrooms by color and shape to make identification simple and accurate in the field, while the text account for each species includes a detailed physical description, information on edibility, season, habitat, range, look-alikes, alternative names, and facts on edible and poisonous species, uses, and folklore. A supplementary section on cooking and eating wild mushrooms, and illustrations identifying the parts of a mushroom, round out this essential guide.

    Nearly 700 species of trees are detailed in photographs of leaf shape, bark, flowers, fruit, and fall leaves -- all can be quickly accessed making this the ideal field guide for any time of year. Note: the Eastern Edition generally covers states east of the Rocky Mountains, while the Western Edition covers the Rocky Mountain range and all the states to the west of it.

    Descriptive text includes measurements, diagnostic details, and information on habitat, range, feeding habits, sounds or songs, flight period, web construction, life cycle, behaviors, folklore, and environmental impact. An illustrated key to the insect orders and detailed drawings of the parts of insects, spiders, and butterflies supplement this extensive coverage.

    The Panda's Thumb will introduce a new generation of readers to this unique writer, who has taken the art of the scientific essay to new heights.Were dinosaurs really dumber than lizards? Why, after all, are roughly the same number of men and women born into the world? What led the famous Dr. Down to his theory of mongolism, and its racist residue? What do the panda's magical "thumb" and the sea turtle's perilous migration tell us about imperfections that prove the evolutionary rule? The wonders and mysteries of evolutionary biology are elegantly explored in these and other essays by the celebrated natural history writer Stephen Jay Gould.

    Presenting a field guide to Australian birds, this illustrated handbook is useful for birdlovers in Australia.

    Douglas H. Ubelaker demonstrates the range of data and interpretations potentially obtainable from human skeletal remains and shows how this information can contribute to the solution of various anthropological problems. It also describes and evaluates basic techniques of skeletal excavation and analysis. Human Skeletal Remains is divided into two sections. The first section reviews the techniques and information needed for excavating and describing skeletal remains and for achieving reliable estimates of stature, sex, and age at death. These chapters should improve the capacity of non-specialists to undertake skeletal excavation and preliminary analysis. The second section discusses additional kinds of information that can be gleaned from suitable samples by experienced skeletal biologists. The information in Human Skeletal Remains is a broad-scale overview and many aspects have been treated in greater detail by others elsewhere. References are provided in the text for the convenience of those interested in more information on specific topics. Technical terminology has been avoided where possible, but accurate recording and description cannot be accomplished without employing the names of individual bones and other skeletal landmarks. Terms most commonly needed for description are included in a glossary. While it is somewhat modest in its intentions, this analysis provides a clarity that extensive tomes cannot supply.

    This involves going through spatial biochemical, electrophysiological, and organismic dynamical systems and patterns that were discovered by pursuing the theme of phase singularities introduced in the original book. In particular the work on excitability in cell membranes will be thoroughly updated as will the references throughout the book.

     A complete manual and an encyclopedic reference work on soilless food production. Technically comprehensive with nearly 400 photographs and detailed drawings on every form of hydroponics for temperate, tropical, or cold climates. A state-of-the-art work widely used by advanced home gardeners and by professional hydroponic growers. Well organized with impeccable academic and professional credentials. Illustrated.

    In this volume the thinkers responsible for the "modern synthesis" of evolutionary biology and genetics come together to analyze that remarkable event. In a new Preface, Ernst Mayr calls attention to the fact that scientists in different biological disciplines differed considerably in their degree of acceptance of Darwin's theories. Mayr shows us that these differences were played out in four separate periods between 1859 and 1947 -- and thus enables us to understand fully why the synthesis was necessary and why Darwin's original theory -- that evolutionary change is due to the combination of variation and selection -- is as solid at the end of the twentieth century as it was in 1859.

    The methods of evolutionary genetics are critically important for the analysis and interpretation of the massive datasets on DNA sequence variation and evolution that are becoming available, as well for our understanding of evolution in general. This book shows readers how models of the genetic processes involved in evolution are made (including natural selection, migration, mutation, and genetic drift in finite populations), and how the models are used to interpret classical and molecular genetic data. The material is intended for advanced level undergraduate courses in genetics and evolutionary biology, graduate students in evolutionary biology and human genetics, and researchers in related fields who wish to learn evolutionary genetics. The topics covered include genetic variation, DNA sequence variability and its measurement, the different types of natural selection and their effects (e.g. the maintenance of variation, directional selection, and adaptation), the interactions between selection and mutation or migration, the description and analysis of variation at multiple sites in the genome, genetic drift, and the effects of spatial structure. The final two chapters demonstrate how the theory illuminates our understanding of the evolution of breeding systems, sex ratios and life histories, and some aspects of genome evolution.
