Download or read book Westcott s Plant Disease Handbook written by R. K. Horst and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1242 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the responsi bility for the fourth edition and now the fifth edition was not taken lightly. The task has been a formidable one. I have always had a great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the two editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in developing the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. " This revision of the Handbook retains the same general format contained in the previous editions. The chemicals and pesticides regulations have been updated; a few taxonomic changes have been made in the bacteria, fungi, and mistletoes; the changing picture in diseases caused by viruses and/or viruslike agents has been described. A few new host plants have been added, and many recently reported diseases as well as previously known diseases listed now on new hosts have been included. In addition, photographs have been replaced where possible, and the color photograph section has been retained.
Download or read book Rust Diseases of Willow and Poplar written by Ming Hao Pei and published by CABI. This book was released on 2005 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been increased interest in growing willow and poplar trees, as fast-growing species that have several purposes, including use as biofuels for energy production. However, silviculture of these trees has been constrained by diseases such as Melampsora rusts. This book provides a comprehensive review of over two decades of extensive study of the rust diseases affecting willow and poplar. It provides insights into the population biology of Melampsora rusts in Europe, China, India and Chile, the genetics of their resistance, and their interaction with their hosts. The book offers information essential to the development of effective and sustainable disease control measures including the use of willow genotype mixtures and biological control agents.

Download or read book Genetics and Genomics of Populus written by Stefan Jansson and published by Springer. This book was released on 2010-03-02 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetics and Genomics of Populus provides an indepth description of the genetic and genomic tools and approaches for Populus, examines the biology that has been elucidated using genomics, and looks to the future of this unique model plant. This volume is designed to serve both experienced Populus researchers and newcomers to the field. Contributors to the volume are a blend of researchers, some who have spent most of their research career on Populus and others that have moved to Populus from other model systems. Research on Populus forms a useful complement to research on Arabidopsis. In fact, many plant species found in nature are – in terms of the life history and genetics – more similar to Populus than to Arabidopsis. Thus, the genetic and genomic strategies and tools developed by the Populus community, and showcased in this volume, will hopefully provide inspiration for researchers working in other, less well developed, systems.
Download or read book Air Pollution Effects on Biodiversity written by J.R. Barker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity is the delicate ecological balance within biological systems such as species and populations. Evidence suggests air pollution disrupts and impoverishes ecosysytems processes, and genetic and population diversity. Based on a symposium conducted by the EPA's Environmental Research Laboratory, this book pulls together current knowledge on the subject, assesses its relevance, and offers a framework for future research on the impact of air pollution on biodiversity through all levels of biological organization. This text is particularly timely due to acid rain and other toxic problems. The text also discusses the best available control technology, management practices, alternative chemicals, and legislative ways to reduce the impact of air pollution on biodiversity.

Download or read book Agroecosystem Diversity written by Gilles Lemaire and published by Academic Press. This book was released on 2018-10-08 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agro-Ecosystem Diversity: Impact on Food Security and Environmental Quality presents cutting-edge exploration of developing novel farming systems and introduces landscape ecology to agronomy. It encompasses the broad range of links between agricultural development and ecological impact and how to limit the potential negative results. Presented in seven sections, each focusing on a specific challenge to sustaining diversity, the book provides insights toward the argument that by re-introducing diversity, it should be possible to maintain a high level of productivity of agro-ecosystems while also maintaining and/or restoring a satisfactory level of environment quality and biodiversity. - Demonstrates that diversified agro-ecosystems can be intensified with environmental quality preserved, restored and enhanced - Includes analysis of economic constraints leading to specialization of farms and regions and the social locking forces resisting to diversification of agro-ecosystems - Presents a global vision of world agriculture and the tradeoff between a necessary increase in food production and restoring environment quality
Download or read book Food Systems and Natural Resources written by United Nations Publications and published by UN. This book was released on 2017-04-03 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global food systems have radically changed over the last 50 years. Food production has more than doubled, diets have become more varied (and often more energy-intense) satisfying people’s preferences in terms of form, taste and quality, and numerous local, national and multi-national food-related enterprises have emerged providing livelihoods for millions. Nonetheless, over 800 million people are still hungry (70% of whom live in rural areas in developing countries), about two billion suffer from poor nutrition, and over two billion are overweight or obese. The resource use implications and environmental impacts of these food systems are significant. In general, of all economic activities, the food sector has by far the largest impact on natural resource use as well as on the environment. An estimated 60% of global terrestrial biodiversity loss is related to food production; food systems account for around 24% of the global greenhouse gas emissions and an estimated 33% of soils are moderately to highly degraded due to erosion, nutrient depletion, acidification, salinization, compaction and chemical pollution. The Food Systems working group of the International Resource Panel has prepared a comprehensive scientific assessment of the current status and dynamics of natural resource use in food systems and their environmental impacts. The IRP identifies opportunities for Resource Smart Food Systems responding to policy-relevant questions like what do sustainable food systems look like from a natural resource perspective? How can resource efficiency improvements be made to enhance food security? How to steer transition towards sustainable food systems? The report looks at food as a crucial connection point (a ‘node’) where various societal issues coincide, such as human dependence on natural resources, the environment, health and wellbeing. Rather than looking separately at resources such as land, water and minerals, the IRP has chosen a systems approach. The report looks at all the resources needed for the primary production of food, as well as for other food system activities (e.g. processing, distribution) considering not only the set of activities, but also the range of actors engaged in them and the outcomes in terms of food security, livelihoods and human health.
