Available in PDF, EPUB and Kindle. Book excerpt: Plant adaptation is a fundamental process in plant breeding. It was the first criterion in the initial domestication of plants thousands of years ago. Adaptedness is generally a quantitative complex feature of the plant, involving many traits, many of which are quantitative. Adaptation to stresses like cold, drought or diseases are among the most central problems in a world grappling with global food security. Modern plant breeding, based on mendelian genetics, has made plant improvement more effective and more precise and selective. Molecular genetics and genetic engineering has considerably increased this selectivity down to single genes affecting single traits. The time has come when plant breeding efficiency may cause loss of genetic resources and adaptation. In these proceedings an effort is made to merge modern plant breeding efficiency with ecological aspects of plant breeding, reflected in adaptation. It is hoped that this merger results in more sustainable use of genetic resources and physical environments. The book is based on 10 keynotes addressing a wide spectrum of themes related to adaptation. In addition each subject is further elaborated in up to three case studies on particular plant species or groups of plants. The keynotes do in fact overlap to some degree and there are articles in this volume that seemingly contradict each other, a common aspect in advanced fields of research. The keen reader may conclude that, in a world where climates and environments are under continuous change and where human society is more and more polarized into a developed and a developing part, adaptation of our cultivated plants has different constraints on yields depending on ecology, and indeed economy.

Download or read book Forest Genetics and Sustainability written by Csaba Mátyás and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 4th International Consultation on Forest Genetics and Tree Building, held in 1998 in Beijing, China, leading scientists were invited to review past achievements, to redefine the role of forest genetics and breeding in contemporary forestry, and to set priorities for future research and development. On the basis of the invited presentations, the volume summarizes the state of knowledge in various fields, such as the impact of forest management and of changing environmental conditions on genetic resources, and the value of genetic markers as indicators for adaptational potential, as well as the tasks of conservation. Detailed reports from the different continents provide a comprehensive diagnosis of the global situation of forest genetics and tree breeding research. The book offers not only an overview of contemporary trends and expected future developments, but also identifies current main problems in funding and cooperation. It may prove therefore useful not only for scientists, university lecturers and advanced students in the field of forestry, ecology and conservation biology, but also for decision makers and managers in companies and conservation organizations.

Download or read book Forest Tree Breeding in Europe written by Luc E Pâques and published by Springer Science & Business Media. This book was released on 2013-05-31 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest tree breeding has been ongoing for more than 70 years across Europe. It has successfully generated improved varieties for the major economical forest tree species. They are part of the present European forestry landscape and largely contribute to intensive wood production and other forest activities. In this book, we describe the state-of-art of breeding for the main forest tree species. We provide a comprehensive, unique and up-to-date overview of the major scientific results and breeding achievements gathered from the many programmes scattered across Europe. The book is divided into 10 chapters, each as a monograph corresponding to a species or group of species Abies spp., (Larix spp., Picea abies, Picea sitchensis, Pinus sylvestris, Pseudotsuga menziesii, and Mediterranean pines; Acer pseudoplatanus, Fraxinus excelsior, and Prunus avium). Each of them is written by a group of experts and focuses on the distribution and economical importance of the species; motivation for breeding and breeding objectives; intraspecific genetic variability, breeding populations and breeding strategy; forest reproductive material deployment including mass-propagation and, prospects and perspectives for joint research and breeding. The book is a unique and up-dated source of information for students, researchers and professionals interested in the genetics and domestication of forest tree species.

Download or read book Forest Development in Cold Climates written by John Alden and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: As forests decline in temperate and tropical climates, highly-developed countries and those striving for greater economic and social benefits are beginning to utilize marginal forests of high-latitude and mountainous regions for resources to satisfy human needs. The benefits of marginal forests range from purely aesthetic to providing resources for producing many goods and services demanded by a growing world population. Increased demands for forest resources and amenities and recent warming of high latitude climates have generated interest in reforestation and afforestation of marginal habitats in cold regions. Afforestation of treeless landscapes improves the environment for human habitation and provides for land use and economic prosperity. Trees are frequently planted in cold climates to rehabilitate denuded sites, for the amenity of homes and villages, and for wind shelter, recreation, agroforestry, and industrial uses. In addition, forests in cold climates reduce the albedo of the earth's surface in winter, and in summer they are small but significant long-lived sinks for atmospheric carbon dioxide. Finally, growth and reproductive success of forests at their geographic limits are sensitive indices of climatic change. As efforts to adapt forests to cold climates increase, however, new afforestation problems arise and old ones intensify. Austral, northern, and altitudinal tree limits are determined by many different factors. Current hypotheses for high-latitude tree limits are based on low growing-season temperatures that inhibit plant development and reproduction.

This book was released on 2013-04-17 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings fonn the outcome of an International Conference on "Impacts of Global change on Tree Physiology and Forest Ecosystems ", held from 26-29 November 1996, at Wageningen, The Netherlands. The conference brought together biologists, ecologists, and forest scientist working in the field of impacts of elevated CO and air pollution on tree physiology and forest ecosystems, and marked the 2 completion of a European COST action on "Impacts of Elevated C02 levels and Air Pollutants on Tree Physiology" (ICAT / COST-614), as well as the conclusion of the frrst phase of an EU-funded project entitled "Long-Term Effects of C02 and Climate Change on European Forests (LTEEF) ", that was carried out under the Environment and Climate Programme of the 4th Framework Programme (contract no's EV5V-CT94-0468 and PECOINIS-CT94-0112). The conference aimed to present an overview of current knowledge of effects of air pollution and climate change, at the biophysical, biochemical and physiological level of trees, against the background of climatic conditions and natural stresses. For the proceedings, we have asked the authors to provide an overview of their recent work, providing an entrance to a particular field of research rather than presenting unpublished material. The meeting took place at the International Agricultural Centre (lAC) with fmancial support provided by the COST-614 secretariat in Brussels. We like to thank mrs. A. van der Bunte of lAC for her support in organising the meeting, mr. A. J. H.
