Book excerpt: Responsible for a high proportion of the world's crop losses, weedstake away food that the world badly needs. They decrease thequality and quantity of vegetable fibers, wool, and hides, andinterfere with fishing, irrigation, hydroelectric power production,and the movement of shipping vessels. In order to recognize thetrue magnitude of the weed problem, and to be better equipped todesign effective weed control methods, it is vital to identify andlearn as much as possible about the many different species of thisdestructive agricultural predator. The culmination of four decades of global research, World Weedspresents comprehensive and up-to-date information on over 100weeds--addressing recent changes in such areas as crop tillagemethods, herbicide use, and agricultural runoff. This monumentalwork, featuring a wealth of original data from the authors,provides extensive coverage of the known biology of each species.Each entry contains a full botanical description, plus importantdetails on habitat requirements and distribution, seed production,ecology, physiology, crop impact, and more. Generously suppliedwith dozens of unique illustrations and species distribution mapscovering over 100 countries, this definitive resource boasts anextensive multilingual index of common names, and a massivebibliography with over 3,000 references to facilitate furtherreading and research. World Weeds is a truly masterful referencethat will be celebrated by weed and crop scientists, botanists, andothers for years to come.
Download or read book Atlas of Weed Mapping written by Hansjoerg Kraehmer and published by John Wiley & Sons. This book was released on 2016-03-17 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds are variously defined as plants growing where they are not wanted, plants that interfere with human activity. Weeds affect everyone in the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding, reducing animal health, preventing water flow, as plant parasites, etc. It is estimated that those problems cause $ billions worth of crop losses annually and the global cost of controlling weeds also runs into many $ billions every year. Atlas of Weed Mapping presents an introductory overview on the occurrence of the most common weeds of the world. The book notably includes: Description of cropping practices and explanations for the global distribution of weeds Invasive plant mapping Aquatics and wetland plants with histological plant details Theoretical and practical aspects of weed mapping Aspects on the documentation of herbicide resistance Biodiversity, rare weeds and the dominance of the most common weeds Fully illustrated with more than 800 coloured figures and a number of tables, this new characterisation of anthropogenic vegetation will be interesting for readers of a great number of disciplines such as agriculture, botany, ecology, geobotany and plant community research. More than a hundred experts have contributed data to this unique compilation.

Download or read book Terrestrial Ecosystems and Biodiversity written by Yeqiao Wang and published by CRC Press. This book was released on 2020-05-19 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Authored by world-class scientists and scholars, The Handbook of Natural Resources, Second Edition, is an excellent reference for understanding the consequences of changing natural resources to the degradation of ecological integrity and the sustainability of life. Based on the content of the bestselling and CHOICE-awarded Encyclopedia of Natural Resources, this new edition demonstrates the major challenges that the society is facing for the sustainability of all well-being on the planet Earth. The experience, evidence, methods, and models used in studying natural resources are presented in six stand-alone volumes, arranged along the main systems of land, water, and air. It reviews state-of-the-art knowledge, highlights advances made in different areas, and provides guidance for the appropriate use of remote sensing and geospatial data with field-based measurements in the study of natural resources. Volume 1, Terrestrial Ecosystems and Biodiversity, provides fundamental information on terrestrial ecosystems, approaches to monitoring, and impacts of climate change on natural vegetation and forests. New to this edition are discussions on biodiversity conservation, gross and net primary production, soil microbiology, land surface phenology, and decision support systems. This volume demonstrates the key processes, methods, and models used through many case studies from around the world. Written in an easy-to-reference manner, The Handbook of Natural Resources, Second Edition, as individual volumes or as a complete set, is an essential reading for anyone looking for a deeper understanding of the science and management of natural resources. Public and private libraries, educational and research institutions, scientists, scholars, and resource managers will benefit enormously from this set. Individual volumes and chapters can also be used in a wide variety of both graduate and undergraduate courses in environmental science and natural science at different levels and disciplines, such as biology, geography, earth system science, and ecology.

Download or read book Seeds written by Carol C. Baskin and published by Elsevier. This book was released on 2014-02-20 with total page 1601 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system; role of seed banks in restoration of plant communities; and seed germination in relation to parental effects, pollen competition, local adaption, climate change and karrikinolide in smoke from burning plants. The database for the world biogeography of seed dormancy has been expanded from 3,580 to about 13,600 species. New insights are presented on seed dormancy and germination ecology of species with specialized life cycles or habitat requirements such as orchids, parasitic, aquatics and halophytes. Information from various fields of science has been combined with seed dormancy data to increase our understanding of the evolutionary/phylogenetic origins and relationships of the various kinds of seed dormancy (and nondormancy) and the conditions under which each may have evolved. This comprehensive synthesis of information on the ecology, biogeography and evolution of seeds provides a thorough overview of whole-seed biology that will facilitate and help focus research efforts. - Most wide-ranging and thorough account of whole-seed dormancy available - Contains information on dormancy and germination of more than 14,000 species from all the continents – even the two angiosperm species native to the Antarctica continent - Includes a taxonomic index so researchers can quickly find information on their study organism(s) and - Provides a dichotomous key for the kinds of seed dormancy - Topics range from fossil evidence of seed dormancy to molecular biology of seed dormancy - Much attention is given to the evolution of kinds of seed dormancy - Includes chapters on the basics of how to do seed dormancy studies; on special groups of plants, for example orchids, parasites, aquatics, halophytes; and one chapter devoted to soil seed banks - Contains a revised, up-dated classification scheme of seed dormancy, including a formula for each kind of dormancy - Detailed attention is given to physiological dormancy, the most common kind of dormancy on earth

Download or read book Biological Diversity written by Michael A. Huston and published by Cambridge University Press. This book was released on 1994-09-15 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key to preserving and managing biodiversity is understanding which processes are important at different scales, and how changes affect different components of biodiversity. In this book, existing theories on diversity are synthesised into a logical framework. Global and landscape-scale patterns of biodiversity are described in the first section. In the second, the spatial and temporal dynamics of diversity are emphasised. The third section develops an integrated set of mechanistic explanations for diversity patterns at the levels of population, community, ecosystem and landscape. Finally, case studies examine diversity patterns in marine and terrestrial ecosystems and the effects of biological invasions. The book concludes with a discussion of the economics of preserving biological diversity. This book will interest research workers and students of ecology, biology and conservation.
Download or read book Peppers written by Vincent M. Russo and published by CABI. This book was released on 2012 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The group of plants called pepper is diverse, containing plants that contribute to the fresh and processed markets and are also used in pharmaceuticals and other non-food commercial products. Peppers developed in tropical regions, but are grown and used in every country where they can be grown and in countries where production is difficult. The book examines peppers from historical, genetic, physiological, production, and post-harvest standpoints following the development of the cultivated crop from the wild type. The diverse examples of pod types that have been developed and their variation in pungency are examined. Production methods, including the importance of fertilization and irrigation are discussed, as are the constraints on production, including pests, pathogens and weeds. Harvesting methods and the post-harvest challenges and opportunities, which exist at a level not found for other crops, will be explored.

This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the massive change in the area of distribution of many world biota across classical biogeographical realms, and of the drastic restructuring of the biotic components of numerous ecosystems, the Scientific Committee on Problems of the Environment (SCOPE) decided at its general Assembly in Ottawa, Canada, in 1982 to launch a project on the 'Ecology of Biological Invasions'. Several regional meetings were subsequently organized within the framework of SCOPE, in order to single out the peculiarities of the invasions that took place in each region, the behaviour of their invasive species and the invasibility of their ecosystems. Most noteworthy among such workshops were one in Australia in August 1984, one concerning North America and Hawaii in October 1984, and one dealing with southern Africa in November 1985. A leitmotiv of these workshops was that most of the invasive species to those regions were emanating from Europe and the Mediterranean Basin, inadvertently or intentionally introduced by man. It was therefore considered as a timely endeavour to organize the next regional meeting in relation to this region. The workshop on 'Biological Invasions in Europe and the Mediterranean Basin' was held in Montpellier, France, 21 to 23 May 1986, thanks to the financial support of SCOPE and of the A.W. Mellon Foundation, and the logistic facilities of the Centre National de la Recherche Scientifique (C.N .R.S.).
Download or read book Allelopathy in Crop Production written by S.S. Narwal and published by Scientific Publishers. This book was released on 2012-11-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Allelopathy offers great potential: (a) to increase agriculture production (food grains, vegetables, fruits, forestry), (b) to decrease harmful effects of modern agricultural practices (multiple cropping, leaching losses from N – fertilizers, indiscriminate use of pesticides viz. weedicides, fungicides, insecticides and nematicides and development of pesticides tolerant /resistant biotypes in pests) on soil health/productivity and on environment and (c) to maintain soil productivity and pollution free environment for our future generations. It is hoped that in the near future the allelopathy may be used in crop production, crop protection, agroforestry and agro-horticultural systems of developed countries. Therefore, it may be one of the strategies to increase agricultural production in Sustainable Agriculture of 21st century. This book is based on the research findings and addresses to various intricate problems of crop production, to which there was no definite answer in the past but now have been attributed to allelopathy.
