A new edition of a highly respected textbook and reference in the rapidly emerging field of equitation science. Equitation Science, 2nd Edition incorporates learning theory into ethical equine training frameworks suitable for riders of any level and for all types of equestrian activity. Written by international experts at the forefront of the development of the field, the welfare of the horse and rider safety are primary considerations throughout. This edition features a new chapter on research methods, and a companion website provides the images from the book in PowerPoint.
Glaciers have always played an important role in human history, and currently, they are carefully observed as climate change sentinels. Glacier melt rate is increasing, and its mass balance is continuously negative. This issue deserves accurate and in-depth studies in order to, adequately, monitor its state. This circumstance in fact endangers the water supply, affecting human settlements but also creating new environments allowing the colonization by pioneer communities and the formation of new landscapes. This book is subdivided into two main sections in order to deal with the two topics of worldwide research on glaciers and ecology in glacial environments. In the first one "Glaciers in the World," several reviews and studies are collected. It is an overview of glaciers, their state, and research carried out in different continents and contexts. The second section "Glacial Ecosystems" focuses, on the other hand, on glacier environments and ecological researches.
Vols. 16-21 include supplement: British empire vegetation abstracts.
The Natural Communities of Georgia presents a comprehensive overview of the state’s natural landscapes, providing an ecological context to enhance understanding of this region’s natural history. Georgia boasts an impressive range of natural communities, assemblages of interacting species that have either been minimally impacted by modern human activities or have successfully recovered from them. This guide makes the case that identifying these distinctive communities and the factors that determine their distribution are central to understanding Georgia’s ecological diversity and the steps necessary for its conservation. Within Georgia’s five major ecoregions the editors identify and describe a total of sixty-six natural communities, such as the expansive salt marshes of the barrier islands in the Maritime ecoregion, the fire-driven longleaf pine woodlands of the Coastal Plain, the beautiful granite outcrops of the Piedmont, the rare prairies of the Ridge and Valley, and the diverse coves of the Blue Ridge. With contributions from scientists who have managed, researched, and written about Georgia landscapes for decades, the guide features more than four hundred color photographs that reveal the stunning natural beauty and diversity of the state. The book also explores conservation issues, including rare or declining species, current and future threats to specific areas, and research needs, and provides land management strategies for preserving, restoring, and maintaining biotic communities. The Natural Communities of Georgia is an essential reference for ecologists and other scientists, as well as a rich resource for Georgians interested in the region’s natural heritage.
Principles and Standards for Measuring Net Primary Production in Long-Term Ecological Studies is the first book to establish a standardized method for measuring net primary productivity (NPP) in ecological research. Primary productivity is the rate at which energy is stored in the organic matter of plants per unit area of the earth's surface. As the beginning stage of the carbon cycle, our ability to accurately measure NPP is essential to any ecological analysis, as well as agronomy, forestry, fisheries, limnology and oceanography. In fact, NPP measurements are fundamental to ecosystem studies at thousands of sites around the world.All 26 LTER sites will be expected to collect and report data using these new standards, but the standards should reach well beyond LTER sites. Identified standards for NPP measurements will allow researchers from diverse biomes to authoritatively compare measurements among their sites. Comparable measurements will build a foundation for a broad scale understanding of the environmental, biological, and nutrition controls on NPP.The book includes chapters for each of the critical biome types, including special techniques that work best in each environment. For example, there are chapters that discuss grassland ecosystems, urban ecosystems, marine pelagic ecosystems, forest ecosystems, and salt marsh ecosystems, among others.
Myth, art, literature, film, and other discourses are replete with depictions of evil plants, salvific plants, and human-plant hybrids. In various ways, these representations intersect with “deep-rooted” insecurities about the place of human beings in the natural world, the relative viability of animalian motility and heterotrophy as evolutionary strategies, as well as the identity of organic life as such. Plants surprise us by combining the appearance of harmlessness and familiarity with an underlying strangeness. The otherness of vegetal life poses a challenge to our ethical, philosophical, and existential categories and tests the limits of human empathy and imagination. At the same time, the resilience of plants, their adaptability, and their integration with their habitat are a perennial source of inspiration and wisdom. Plants and Literature: Essays in Critical Plant Studies examines the manner in which literary texts and other cultural products express our multifaceted relationship with the vegetable kingdom. The range of perspectives brought to bear on the subject of plant life by the various authors and critics represented in this volume comprise a novel vision of ecological interdependence and stimulate a revitalized sensitivity to the relationships we share with our photosynthetic brethren.
