Download or read book Pollination of Cultivated Plants in the Tropics written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 1995 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bulletin, based on contributions from various contributors and edited by Dr. D.W. Roubik, introduces the reader to various aspects of natural and insect pollination. It discusses the pollinators themselves, and the ecological and economic importance of pollination, as well as applied pollination in temperate, tropical oceanic islands and mainland tropics, and alternatives to artificial pollinator populations. Prospects for the future are also discussed. Chapter 2 deals with successful pollination with pollinator populations, the evaluation of pollinators and floral biology and research techniques. The behaviour of pollinators and plant phenology and various case studies on the preparation of pollinators for use in tropical agriculture are also discussed. A glossary and various appendices regarding cultivated and semi-cultivated plants in the tropics, pollination contracts and levels of safety of pesticides for bees and other pollinators are included.
Download or read book Yvain written by Chretien de Troyes and published by Yale University Press. This book was released on 1987-09-10 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The twelfth-century French poet Chrétien de Troyes is a major figure in European literature. His courtly romances fathered the Arthurian tradition and influenced countless other poets in England as well as on the continent. Yet because of the difficulty of capturing his swift-moving style in translation, English-speaking audiences are largely unfamiliar with the pleasures of reading his poems. Now, for the first time, an experienced translator of medieval verse who is himself a poet provides a translation of Chrétien’s major poem, Yvain, in verse that fully and satisfyingly captures the movement, the sense, and the spirit of the Old French original. Yvain is a courtly romance with a moral tenor; it is ironic and sometimes bawdy; the poetry is crisp and vivid. In addition, the psychological and the socio-historical perceptions of the poem are of profound literary and historical importance, for it evokes the emotions and the values of a flourishing, vibrant medieval past.

Download or read book Ecology and Natural History of Tropical Bees written by David W. Roubik and published by Cambridge University Press. This book was released on 1992-05-29 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans have been fascinated by bees for centuries. Bees display a wide spectrum of behaviours and ecological roles that have provided biologists with a vast amount of material for study. Among the types observed are both social and solitary bees, those that either pollinate or destroy flowers, and those that display traits allowing them to survive underwater. Others fly mainly at night, and some build their nests either in the ground or in the tallest rain forest trees. This highly acclaimed book summarises and interprets research from around the world on tropical bee diversity and draws together major themes in ecology, natural history and evolution. The numerous photographs and line illustrations, and the large reference section, qualify this book as a field guide and reference for workers in tropical and temperate research. The fascinating ecology and natural history of these bees will also provide absorbing reading for other ecologists and naturalists. This book was first published in 1989.

Download or read book Biological Diversity of Mexico written by T. P. Ramamoorthy and published by . This book was released on 1993 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is among the richest countries in the world in terms of the number of native animal and plant species. Found in a wide variety of habitats--from alpine meadows and tropical forests to vast stretches of desert and isolated pockets of biogeographical uniqueness--these species comprise a fascinating, important, and vastly underutilized biological laboratory. This volume presents a collection of selected papers that explore this marvelous biological abundance. The book is divided into six parts. The first section sets the stage with geological and paleobotanical overviews; the succeeding five sections employ a strong taxonomic base to document species richness, endemism and distribution for animals and plants, followed by reviews of contrasting ecosystems and plants that are closely associated with humans. The last section summarizes the disheartening rate of habitat destruction which threatens to diminish this diversity. In addition to the purely scientific value of this important work, it provides the much-needed basic data that will help conservation policymakers assess and respond to Mexico's ecological evolution.
Download or read book Obligate Pollination Mutualism written by Makoto Kato and published by Springer. This book was released on 2017-05-09 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of our current understanding of mutualism origin, plant–pollinator specificity, mutualism stability, and reciprocal diversification. In particular, it focuses on the natural history and evolutionary history of the third example of obligate pollination mutualism, leafflower–leafflower moth association, which was discovered in the plant family Phyllanthaceae by the lead editor and then established by the editors and their coworkers as an ideal model system for studies of mutualism and the coevolutionary process. This work brings together the knowledge they have gained through an array of research conducted using different approaches, ranging from taxonomy, phylogenetics, ecology, and evolutionary biology to biogeography. Richly illustrated with numerous original color photographs, the volume consists of 13 chapters and is divided into three main parts: natural history, ecology, and evolution. It begins by showcasing numerous examples of plant–animal interactions and their origins to guide readers in the world of leafflowers and their pollinators. The immense diversity of Phyllanthaceae and pollinator moths is then explored, and in the following 7 chapters mutualism is discussed from a range of ecological and evolutionary points of view. The final chapter presents a review of the evolution and variety of obligate pollination mutualisms. This book offers researchers and students in the field of ecology, botany, evolutionary biology, pollination biology, entomology, and tropical biology fascinating insights into why such a costly pollination system has evolved and why Phyllanthaceae is so diverse despite the inconspicuousness of their flowers.
