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 2007-04-13 with total page 326 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 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.

[Author] [Author]. This book was released on 2024-06-04 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent population growth in Uzbekistan necessitates increase in productivity of agricultural crops extensively or intensively. This report shows how the concept of a farmer field school can help to improve the food security of small farmers and to involve uncultivated desert lands in production of food crops. By reading this report, you will find out how two farmer field schools were implemented in research sites located in Durmon and Chuya villages of Uzbekistan. The report explains that the improved wheat variety resulted in 116 to 241 percent higher grain yield than the local variety. The second major outcome specified in this report is that winter chickpea was successfully cultivated in the cold winter desert. Read this report to learn the following important impacts: -Adoption of improved wheat varieties would play an important role in improving food security of the farmers living in the cold winter desert of Uzbekistan. -Food security in the cold winter deserts can be improved by cultivating chickpea on previously uncultivated land and help ease pressure on the limited cultivable land in Uzbekistan.

Download or read book Honey Bee Biology written by Brian R. Johnson and published by Princeton University Press. This book was released on 2023-06-06 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive and up-to-date general reference book on honey bee biology Honey bees are marvelously charismatic organisms with a long history of interaction with humans. They are vital to agriculture and serve as a model system for many basic questions in biology. This authoritative book provides an essential overview of honey bee biology, bringing established topics up to date while incorporating emerging areas of inquiry. Honey Bee Biology covers everything from molecular genetics, development, and physiology to neurobiology, behavior, and pollination biology. Placing special attention on the important role of bees as pollinators in agricultural ecosystems, it incorporates the latest findings on pesticides, parasites, and pathogens. This incisive and wide-ranging book also sheds vital light on the possible causes of colony collapse disorder and the devastating honey bee losses we are witnessing today. The study of honey bees has greatly expanded in recent years and there is more interest in these marvelous creatures than ever before. Honey Bee Biology is the first up-to-date general reference of its kind published in decades. It is a must-have resource for social insect biologists, scientifically savvy beekeepers, and any scientist interested in bees as a model system.

Download or read book New Perspectives on the Biology of Nectaries and Nectars written by Clay Carter and published by Frontiers Media SA. This book was released on 2019-08-27 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The number of currently known, described and accepted plant species is ca 374,000, of which approximately 295,00 (79%) are angiosperms. Almost 90% of this huge number of flowering plants is pollinated by animals (mostly insects) via nectar-mediated interactions. Notably, three-fourths of the leading global crop plants produce nectar and are animal pollinated, which is estimated to account for one-third of human food resources. Nectar can also be produced on tissues outside of flowers, by so-called extrafloral nectaries, and commonly mediate interactions with ‘body-guard’ ants and other pugnacious insects that defend the plant from herbivores. Extrafloral nectar is present in almost 4,000 plant species, a majority of them in the angiosperms. This brief summary on the occurrence of nectar in the plant kingdom is just to highlight that nectar has a fundamental role in two basal functions that allow the maintenance of our ecosystems: sexual plant reproduction and protection of plants from herbivory. Despite playing essential ecological and evolutionary functions, our current knowledge about nectar is largely incomplete; however, new research directions and perspectives on nectaries and nectars have arisen in recent years. In the last two decades, there were only a few ‘moments’ in which nectar was the main character in international meetings or in published books. In 2002, the first (and only) international meeting “Nectar and nectary: from biology to biotechnology” dedicated exclusively to nectar and nectaries was held in Italy (Montalcino, Siena) and in 2003 the proceedings were published in a special volume of Plant Systematics and Evolution (238, issue 1-4). In 2007, the book Nectar and Nectaries was published (Springer) with most of the contributions provided by authors that attended the meeting in Italy. Another book dedicated to nectar was published in 2015 (Nectar: Production, Chemical Composition and Benefits to Animals and Plants, Nova Science Publishers) covering aspects mainly related to nectar chemical composition and plant-pollinator interactions. Similarly, symposia focused on nectar have been organized within the International Botanical Congress in 2011 and 2017. Considering that the last few years has yielded essential developments in the understanding of nectar biology, we thought now is the moment to further stimulate research on this important topic. This aim has been met through 18 papers published in our Research Topic New Perspectives on the Biology of Nectaries and Nectars, with subjects spanning evolution and ecology to nectar chemistry and nectary structure.
