Book Description
Consider this: Without interaction between animals and flowering plants, the seeds and fruits that make up nearly eighty percent of the human diet would not exist. In The Forgotten Pollinators, Stephen L. Buchmann, one of the world's leading authorities on bees and pollination, and Gary Paul Nabhan, award-winning writer and renowned crop ecologist, explore the vital but little-appreciated relationship between plants and the animals they depend on for reproduction -- bees, beetles, butterflies, hummingbirds, moths, bats, and countless other animals, some widely recognized and other almost unknown. Scenes from around the globe -- examining island flora and fauna on the Galapagos, counting bees in the Panamanian rain forest, witnessing an ancient honey-hunting ritual in Malaysia -- bring to life the hidden relationships between plants and animals, and demonstrate the ways in which human society affects and is affected by those relationships. Buchmann and Nabhan combine vignettes from the field with expository discussions of ecology, botany, and crop science to present a lively and fascinating account of the ecological and cultural context of plant-pollinator relationships. More than any other natural process, plant-pollinator relationships offer vivid examples of the connections between endangered species and threatened habitats. The authors explain how human-induced changes in pollinator populations -- caused by overuse of chemical pesticides, unbridled development, and conversion of natural areas into monocultural cropland-can have a ripple effect on disparate species, ultimately leading to a "cascade of linked extinctions."

Book Description
The diversity of lifestyles, behaviors, and life cycles that bees possess is astounding, and Bees of the World is a well-rounded reference to these fascinating creatures. Presenting comprehensive coverage of bee species from around the world in an engaging format, this volume will delight readers and inform them about all aspects of the life of bees. The book first answers the question: What are bees? It then goes on to discuss the different families and distribution of bees. The expert authors also describe solitary bees - miners, masons, leaf-cutters, and carpenters - as well as social bees. Readers gain insight into the intricacies of bees' lives through the authoritative text, with special coverage of bees and their special relationship with flowers. The history of association between humans and bees, especially the honey bee Apis mellifera, is also addressed. Bees of the World is fully illustrated with detailed line illustrations and stunning color photographs, making it an ideal reference source for professional naturalists and amateurs alike.

Book Description
Sustainable agriculture is a key concept for scientists, researchers, and agricultural engineers alike. This book focuses on the FAM- project (FAM Munich Research Network on Agroecosystems) of the 1990s as a means to assessing, forecasting, and evaluating changes in the agroecosystems that are necessary for agricultural sustainability. The management of two separate management systems: an organic and an integrated farming system are described to provide an interdisciplinary approach Changes of matter fluxes in soils, changes of trace gas fluxes from soils, precision farming in a small scale heterogen landscape, influence of management changes on flora and fauna, as well as the development of agroecosystem models, the assessment of soil variability and the changes in nutrient status are important aspects of this book.* Contains detailed results and insight of a long-time project on agricultural sustainability* Provides an interdisciplinary approach for comprehensive understanding by scientists and researchers of soil, plants, agriculture, and environment * Includes an international perspective

Book Description
ÿThe genus Chlerogella historically has been one of the most infrequently encountered lineages of augochlorine bees (Apoidea: Anthophila: Halictidae: Augochlorini). By 1993 only three species were described and less than 40 specimens were known of a group presumed to be species poor and of limited geographic scope. With their frequently elongate heads and characteristic habitus, species of the genus are quite distinctive, and although the available material of these rare bees has grown to only 165, the number of species and their broader distribution has expanded significantly. This volume completes a revision of the world?s species of Chlerogella, completing the large South American fauna (Part I, covering Central America, is available in ZooKeys 23). In total, the genus has grown from three species to 34 (27 are treated in the current work). Color photomicrographs, detailed descriptions, and keys are provided to permit identification of the currently known taxa and aid the future discovery of new species. Unfortunately, almost nothing is known of the biology of these fascinating bees and this work will hopefully aid the discovery and elucidation of their natural history.
