Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Download or read book Bee Pollination in Agricultural Ecosystems written by Rosalind R. James and published by Oxford University Press. This book was released on 2008-09-09 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the interplay among bees, agriculture and the environment. Both managed and wild bees are critical for successful pollination of numerous fruit, vegetable, oilseed and legume seed crops and are considered here. So is treatment of how bees also impact the agro-ecosystem in ways beyond simple pollination, such as by transporting pollen from genetically modified plants and by enhancing biological control strategies. The principles and examples are international. The concept is in line with current thinking of pollination as an important ecological process, and an understanding of agriculture as disturbance ecology.
Download or read book Keeping The Bees written by Laurence Packer and published by HarperCollins Canada. This book was released on 2010-09-21 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: A world without bees would be much less colourful, with fewer plants and flowers. But that's not all -- food would be in much shorter supply, and available in much less variety. While the media focuses on colony-collapse disorder and the threats to honey bees specifically, the real danger is much greater: all bees are at risk. And because of the integral role these insects play in the ecology of our planet, we may be at risk as well. The life of Laurence Packer, a melittologist at Toronto's York University, revolves around bees, whether he's searching for them under leaves in a South American jungle or identifying new species in the desert heat of Arizona. Packer often finds himself in exotic and even dangerous locales, risking snake bites, sunstroke, and even the ire of other scientists. Everywhere he travels, he discovers the same unsettling trend: bees are disappearing. And since bees are responsible for up to one-third of our food supply, the consequences are frightening.
Download or read book Pollination Biology written by Dharam P. Abrol and published by Springer Science & Business Media. This book was released on 2011-10-05 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Download or read book Crop Pollination by Bees Volume 1 written by Keith S. Delaplane and published by CABI. This book was released on 2021-07-30 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the second half of the 20th Century, our agricultural bee pollinators have faced mounting threats from ecological disturbance and pan-global movement of pathogens and parasites. At the same time, the area of pollinator-dependent crops is increasing globally with no end in sight. Never before has so much been asked of our finite pool of bee pollinators. This book not only explores the evolutionary and ecologic bases of these dynamics, it translates this knowledge into practical research-based guidance for using bees to pollinate crops. It emphasizes conserving wild bee populations as well as culturing honey bees, bumble bees, and managed solitary bees. To cover such a range of biology, theory, and practice from the perspectives of both the pollinator and the crop, the book is divided into two volumes. Volume 1 focuses on bees, their biology, coevolution with plants, foraging ecology and management, and gives practical ways to increase bee abundance and pollinating performance on the farm. Volume 2 (also available from CABI) focuses on crops, with chapters addressing crop-specific requirements and bee pollination management recommendations. Both volumes will be essential reading for farmers, horticulturists and gardeners, researchers and professionals working in insect ecology and conservation, and students of entomology and crop protection.
