In Vitro Methods for Conservation of Plant Genetic Resources
ISBN: 9780412338700 / Angielski / Twarda / 247 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. However, the transition from primitive to 'advanced' cultivars has had the effect of narrowing the genetic base. This has happened in two distinct ways: (1) selection for relative uniformity, resulting in 'pure' lines, multi- lines, single or double hybrids, etc.; and (2) selection for closely defined objectives. Both of these processes have resulted in a marked reduction in genetic variation. At the same time, there has been a tendency to restrict the gene pool from which parental material has been drawn. This is a result of the high level of productivity achieved when breeding within a...

Terrestrial Slugs: Biology, Ecology and Control
ISBN: 9780412368103 / Angielski / Twarda / 428 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In recent years slugs have become increasingly important, partly because several species are agricultural and horticultural pests and partly because theyhave proved to be useful experimental animals, particularly in the field of neurophysiology. Most of the early works which included slugs were essentially taxonomic but the book byTaylor (1902-1907) contained a great deal of biological information about slugs, some of which is still relevant today. The publication of the book by Runham and Hunter (1970) represented a milestone in slug research, providing a comprehensive survey of current...

Nematode Interactions
ISBN: 9780412461309 / Angielski / Twarda / 377 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the...

Maintaining Biodiversity in Forest Ecosystems
ISBN: 9780521637688 / Angielski / Miękka / 716 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The maintenance of the earth's biological diversity is widely seen as both necessary for ecosystem health and aesthetically desirable. This book focuses on how biodiversity can be maintained in forested ecosystems, particularly in those forests that are subject to timber harvesting. At the core of the book lies the concept that diversity should be conserved in all its forms--from the smallest microbes to the largest trees, and at all levels of organization--from genes to whole ecosystems. Introductory chapters on biodiversity and ecological forestry lead on to sections dealing with management...

It is our conviction that professional skill in forestry will develop more readily and more efficiently if forestry students are presented with a clear understanding of the im- pact of the physical factors that both enhance and inhibit forestry activities. Part I is analytic, written as a basic text for undergradu- ates in courses such as logging, transport, forest engineer- ing and even forest management. It deals with the fundamen- tals of technology in forestry as determined by the physical environment. The analytic approach serves two purposes, to bring about a clear understanding of the...

Frugivory and Seed Dispersal: Ecological and Evolutionary Aspects
ISBN: 9780792321415 / Angielski / Twarda / 392 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Any scientific discipline needs a theoretical framework to guide its development and to sharpen the questions its researchers pursue. In biology, evolution is the grand theoretical framework, and an his torical perspective is necessary to understand present-day biological conditions. In its formative years, the modern study of the fruit-frugivore mutualism was guided by the 'specialist-generalist' paradigm developed by D. Snow, D. McKey, and H. Howe. Howe reviews the current status of this evolution ary paradigm and points out that it has been dismissed by many workers before being adequately...

Human Activities and the Tropical Rainforest: Past, Present and Possible Future
ISBN: 9780792348580 / Angielski / Twarda / 206 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Arising initially from a conference, the papers published here have been integrated into book form to provide information on human activities and the tropical rainforest in the past and present, and on the possible future of the rainforest, in a unique way. Other books have considered some, but not all, of these themes; however, none has stressed the continuity of change over time and its possible outcome for the people of the forest as well as for the forest itself.
Because of the approach taken, this book should appeal across traditional disciplinary boundaries. Indeed a prime aim has... Arising initially from a conference, the papers published here have been integrated into book form to provide information on human activities and the ...

Plant Genetic Resources of Legumes in the Mediterranean
ISBN: 9780792367079 / Angielski / Twarda / 380 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Genetic erosion, that is, the loss of native plant and genetic diversity has been exponential from the Mediterranean Basin through the Twentieth century. This careless eradication of species and genetic diversity as a result of human activities from a 'hot-spot' of diversity threatens sustainable agriculture and food security for the temperate regions of the world. Since the early 1900s there has been a largely ad hoc movement to halt the loss of plant diversity and enhance its utilisation. The Convention on Biological Diversity and Food and Agriculture Organisation of the United Nations...
