Medicinal Plants
Medicinal Plants: Culture, Utilization and Phytopharmacology covers over 400 species. Each chapter gathers valuable information from a wide variety of sources, and supplies it to the user in convenient table format, arranged alphabetically by scientific name, followed by the common name. Data topics include: major constituents (active ingredients) and medicinal values of plants; toxicity or hazardous components; essential oils; value-added products and possible uses; cultivation and harvesting; diseases and insects found in medicinal plants. Three appendices (alphabetical listing of plants by common name, followed by the scientific name; essential oils and their derivation; active ingredients and their sources) provide handy cross-references to the Tables.
The Beekeeper's Handbook
Since 1973, tens of thousands of first-time and experienced beekeepers alike have relied on The Beekeeper's Handbook as the best single-volume guide to the hobby and profession of beekeeping. Featuring clear descriptions and authoritative content, this handbook provides step-by-step directions accompanied by more than 100 illustrations for setting up an apiary, handling bees, and working throughout the season to maintain a healthy colony of bees and a generous supply of honey. This book explains the various colony care options and techniques, noting advantages and disadvantages, so that beekeepers can make the best choices for their own hives. This fourth edition has been thoroughly redesign...
Honeybee Ecology
From the acclaimed author of Honeybee Democracy, a classic account of the ecological factors that shape the social lives of honeybees For many years, research on honeybee social life dealt primarily with the physiological processes underlying the social system of the bee rather than the ecological factors that have shaped its societies. Thomas Seeley’s landmark book unites the two approaches, emphasizing ecological studies of honeybee social behavior while also offering fresh perspectives on honeybee behavior and communication. It covers a broad range of topics, from adaptiveness of worker sterility and the economics of nest construction to information-center foraging, individual versus colony level selection, sex ratio evolution, colonial thermoregulation, evolution of colony defense, and adaptive radiation in colony design. Honeybee Ecology presents honeybees as a model system for investigating advanced social life among insects from an evolutionary perspective.
The Lives of Bees
Seeley, a world authority on honey bees, sheds light on why wild honey bees are still thriving while those living in managed colonies are in crisis. Drawing on the latest science as well as insights from his own pioneering fieldwork, he describes in extraordinary detail how honey bees live in nature and shows how this differs significantly from their lives under the management of beekeepers. Seeley presents an entirely new approach to beekeeping--Darwinian Beekeeping--which enables honey bees to use the toolkit of survival skills their species has acquired over the past thirty million years, and to evolve solutions to the new challenges they face today. He shows beekeepers how to use the principles of natural selection to guide their practices, and he offers a new vision of how beekeeping can better align with the natural habits of honey bees.
The pollination of cultivated plants: A compendium for practitioners
More than twenty years ago, the Food and Agriculture Organization of the United Nations contributed to the growing recognition of the role of pollination in agricultural production, with the publication of “The Pollination of Cultivated Plants in the Tropics”. Since that time, the appreciation of pollinators has grown, alongside the realization that we stand to lose them. But our knowledge and understanding of crop pollination, pollinator biology, and best management practices has also expanded over this time. This volume is the second of two “compendiums for practitioners”, sharing expert knowledge on all dimensions of crop pollination in both temperate and tropical zones. The focus in this second volume is on management, study and research tools and techniques.
