This book was released on 2020-05-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the discipline of pollination ecology moves from describing the extent of a pollinator crisis, to identifying what can be done about it, there is a need to share and highlight very practical measures that will support sustainable crop biotic pollination services. Identifying these practices will require a mix of farmer and natural historian knowledge and scientific research. In this publication, we will outline the practices that have been so far identified, and what experiences may contribute to sharing the effectiveness of these measures under different circumstances.
Download or read book Bee Pollination in Agricultural Ecosystems written by Rosalind James and published by Oxford University Press. This book was released on 2008-09-09 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many agricultural crops, bees play a vital role as pollinators, and this book discusses the interplay among bees, agriculture, and the environment. Although honey bees are well recognized as pollinators, managed bumble bees and solitary bees are also critical for the successful pollination of certain crops, while wild bees provide a free service. As bees liberally pass pollen from one plant to the next, they also impact the broader ecosystem, and not always to the benefit of humankind. Bees can enhance the unintentional spread of genes from genetically engineered plants, and may increase the spread of invasive weeds. Conversely, genetically engineered plants can impact pollinators, and invasive weeds can supply new sources of food for these insects. Bees' flower-visiting activities also can be exploited to help spread biological control agents that control crop pests, and they are important for native plant reproduction. Managing bees for pollination is complex and the factors that must be taken into consideration are treated here, including bee natural history, physiology, pathology, and behavior. Furthermore, transporting bees from native ranges to new areas for pollination services can be controversial, and needs to be done only after assuring that it will not disrupt various ecosystems. Even though bees are small, unobtrusive creatures, they play large roles in the ecosystem. The connection between bees and humankind also is symbolic of a broader interconnection between humans and the natural world.

Available in PDF, EPUB and Kindle. Book excerpt: A completely revised and rewritten edition of this comprehensive survey of the botanical problems of pollination ecology approached from both a theoretical and a practical viewpoint. Examples are drawn from all geographical areas where pollination has been studied and general principles are illustrated by a number of concrete examples. Introductory chapters survey the technical problems and draw comparisons with spore dissemination in cryptogams and pollination in gymnosperms. The following chapters deal with angiosperm pollination and are divided into three parts: organs involved in pollination, flower types and pollinator activities

Download or read book Pests and Pollinators of Vegetable and Oilseed Crops written by Dharam P. Abrol and published by Scientific Publishers. This book was released on 2019-03-21 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pest management for vegetable crops and safety provision for the pollinators is a challenging task in the context to increase vegetable productivity without upsetting the ecological balance. The book Pests and Pollinators of Vegetable and Oilseed Crops aims to integrate and develop pest control strategies by minimizing their impact on beneficial insect species such as natural enemies and pollinators for enhancing fruit production and quality. A detailed account is provided on pests and pollinators of oilseed crops such as Cruciferous, Solanaceous, Umbelliferous, Cucurbitaceous, Malvaceous, Leguminous and Alliaceae. The compilation of this book is unique as it does not deal only with the conventional way of pest management for different crops; it takes into consideration the role of pollinators and their profitable utilization in the larger context of ecologically based pest management and safety of pollinators. An exemplary attempt is made to promote a large, diverse, sustainable and dependable bee pollinator workforce that can meet the challenges of optimizing food production in the twenty-first century and beyond.

Book excerpt: "This beautifully illustrated book reviews scientific and technological information about the world's major food plants and their culinary uses. An introductory chapter discusses nutritional and other fundamental scientific aspects of plant foods. The 100 main chapters deal with a particular species or group of species. All categories of food plants are covered, including cereals, oilseeds, fruits, nuts, vegetables, legumes, herbs, spices, beverage plants and sources of industrial food extracts. Information is provided on scientific and common names, appearance, history, economic and social importance, food uses (including practical information on storage and preparation), as well as notable curiosities. There are more than 3000 literature citations in the book and the text is complemented by over 250 exquisitely drawn illustrations. Given the current, alarming rise in food costs and increasing risk of hunger in many regions, specialists in diverse fields will find this reference work to be especially useful. As well, those familiar with Dr. Small's books or those with an interest in gardening, cooking and human health in relation to diet will want to own a copy of this book."--Publisher's web site.
