Download or read book High Mountain Conservation in a Changing World written by Jordi Catalan and published by Springer. This book was released on 2017-08-03 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.
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 Plant Growth Substances written by Richard N. Arteca and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a convenient, single-source reference, this book examines plant growth substances and their relationship to a wide range of physiological processes, ranging from seed germination through the death of the plant. If offers a clear illustration of the pragmatic uses of plant substances in agriculture and demonstrates how basic laboratory research has translated into increased production and profit for the grower. This work begins by building a solid foundation in the subject, which contains historical aspects and fundamental concepts, and provides a methodology for extraction, purification, and quantification of plant growth substances. This forms the basis for understanding the ensuing chapters that explore the many processes involving plant growth substances, including: * seed germination * seedling growth * rooting * dormancy * juvenility * maturity * senescence * flowering * abscission * fruit set * fruit growth * fruit development * premature drop * ripening * promotion of fruit drop * tuberization * photsynthesis * weed control. Providing a detailed examination of plant growth substances and their relationships to specific physiological plant processes, Plant Growth Substances gives students, researchers, and professionals a much needed reference.

Download or read book Economic Botany written by S. L. Kochhar and published by Cambridge University Press. This book was released on 2016-07-01 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an up-to-date account of important crops grown worldwide. It provides detailed discussion on the history of plant exploration, migration, domestication and distribution, and crop improvement. The text starts with the origin and diversification of cultivated plants, followed by discussion on tropical, subtropical and temperate crops that are sources of food, beverages, spices and medicines, as well as plant insecticides, timber plants and essential oil-yielding plants. The genetic and evolutionary aspects of different plants and their health benefits are highlighted. The book covers topics dealing with biodiversity conservation, petro-crops, ethnobotanical studies, and important sub-tropical and temperate plants that have commercial importance. The significance of major plant species under each category is described in detail. Illustrated with numerous well-labelled line diagrams and pictures, this book will be useful for students of botany, food and nutrition, forestry, agriculture, horticulture, plant breeding and environmental science.

Download or read book Brassinosteroids written by Horace G. Cutler and published by . This book was released on 1991 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first and only comprehensive reference on brassinosteroids, a new class of plant hormones. It provides a survey of the chemistry, synthesis, physiology, and practical applications of brassinosteroids, in experimental and agricultural references alike. With contributions from all over the world, including Africa, Asia, Europe, and North America, this volume presents an accurate and comprehensive picture of the present state of research and development in brassinosteroids. Of special interest is the presentation of results of large-scale field trials in China, which strongly indicate the economic potential of these compounds as environmentally benign agricultural chemicals to significantly increase crop yields.

Download or read book Iron Age and Romano British Settlements and Landscapes of Salisbury Plain written by Michael Fulford and published by Wessex Archaeology Reports. This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the results of a series of fieldwalking surveys and excavations of Iron Age and Romano-British sites in two areas of the Salisbury Plain Training Area. Altogether some 18 new settlement sites were discovered of which 13 were Romano-British, three were predominantly Iron Age, and two produced evidence of Middle-Late Bronze Age occupation. Small-scale excavation was undertaken at eight enclosures and field systems, accompanied by targeted environmental sampling.An increase in enclosure through to the later Iron Age was revealed, when there was evidence for settlement abandonment followed by a further development of unenclosed settlement and the emergence of nucleated villages such as Chisenbury Warren in the Late Iron Age and through the Romano-British period.
