Japanese macaques (Macaca fuscata) have been studied by primatologists since 1948, and considerable knowledge of the primate has been accumulated to elucidate the adaptation of the species over time and to distinct environments in Japan. The Japanese macaque is especially suited to intragenera and interpopulation comparative studies of behavior, physiology, and morphology, and to socioecology studies in general. This book, the most comprehensive ever published in English on Japanese macaques, is replete with contributions by leading researchers in field primatology. Highlighted are topics of intraspecific variations in the ecology and behaviors of the macaque. Such variations provide evidence of the ecological determinants on this species' mating and social behaviors, along with evidence of cultural behavior. The book also addresses morphology, population genetics, recent habitat change, and conflicts with humans, and attests to the plasticity and complex adaptive system of macaque societies. The valuable information in this volume is recommended reading for researchers in primatology, anthropology, zoology, animal behavior, and conservation biology.

There are several books on properties of chitin and associated biomolecules and their biochemical significance. However, the present volume deals with a wide variety of biogeochemical and organic geochemical aspects of this vital macromolecule written by leading authors and experts in the field. Each chapter is carefully peer reviewed and is an updated account of recent research in isotopic, nanostructural, biochemical, microstructural, geochemical, paleontological and experimental aspects of chitin formation, distribution and preservation in the environment and earth history.

Horse Pasture Management, Second Edition provides updated coverage on strategies for managing behavior, grouping, environments and feeding needs of grazing horses. Sections cover the structure, function and identification of forages, continuing into nutritional value of pasture plants. Management of soil, the function of a pasture ecosystem and management of plants in a pasture is covered next, followed by forage yield determination, horse grazing behavior, feed choices of horses, management of grazing horses, and how to calculate how many horses should be grazing relative to land size. Advantages of grazing more than one species of animal are described. Management of hay and silage are included since year-round grazing is not possible on many horse farms. Several chapters deal with interactions of a horse farm with the environment, including climate and weather and other living things. The book also covers strategies for managing manure, erosion, and water quality. It is ideal for researchers, scientists and students involved in animal science, specifically equine studies. Agriculturists, equine managers and veterinarians will also find this book useful.

Nature helps... of course at first itself by developing measures that give bacteria, fungi, plants and animals a chance to be successful in their struggle for life. As a latecomer on Earth, Homo sapiens was gifted with some droplets of the divine spirit of recognition and thus became able to observe, to analyse and recombine skills of other living beings and to use them for his overwhelming career over the last 10,000 years.Of course fungi, plants, animals and even bacteria were primarily used by mankind as food or as lifestyle products such as beer, but soon it became clear that there was much more potential hidden in these organisms and that they could be used for other purposes, too. Extracts of plants and fungi were recognized as powerful remedies, as medicines, as insecticides or acarizides, as repellents against parasites or even as weapons, e.g. when poisonous compounds from frogs or plants were applied to arrowheads. Over the last 110 years the pharmaceutical industry has often simulated nature by analyzing complex organic substances taken from living organisms and then producing by synthesis absolutely pure compounds, which mostly consisted of only one single active substance. These products had the advantage of acting against precisely one target and thus produced fewer possible side effects than the complex plant extracts. However, the more serious side effect was that disease agents could develop resistances to pure medicinal products much more easily. Thus after 70 years of excellent prospects for chemotherapy, some dark clouds appeared and quickly gathered, so that several therapeutic remedies now no longer work. Therefore in many countries - especially in those where the pure chemotherapeutics are too expensive for the poor population - the cry "back to nature" is becoming louder and louder. This has led to an enormous increase of studies that again use natural extracts as remedies in the fight against diseases. The present book summarizes examples of promising aspects in a broad spectrum of applications and shows how extracts derived from bacteria, marine organisms, plants or even animals may help to treat infectious diseases, how such organisms may keep away parasites and pests from the bodies of plants or animals, including humans, and how they can be used directly to aid in diagnosis, promote wound healing and even to help catch criminals. These 15 chapters offer not only basic research on these different fields, but also show how useful and effective products can be developed from research.
