Ecology of Soil Seed Banks


Book Description

Ecology of Soil Seed Banks examines the factors that influence seed bank dynamics and the variety of patterns found among different species. This book presents seed banks in a community context to explore the ecological implications of different patterns, and thus begin the development of a synthesis by comparing various communities. Organized into five parts, this book first examines the general processes that influence inputs or losses from the seed bank, including predation, dormancy/germination mechanisms, and their evolutionary importance. Then, this text examines seed banks in a community context. Only eight vegetation types are included, but the range in diversity of life form, length of growing season, and dominant environmental conditions allow comparisons of seed bank patterns. This book also explores the role of seed banks in vegetation management. This reference material will be a valuable reference material to population and community ecologists and managers. Evolutionary consequences of seed banks should be of interest to population and theoretical biologists.




Community Seed Banks


Book Description

Community seed banks first appeared towards the end of the 1980s, established with the support of international and national non-governmental organizations. This book is the first to provide a global review of their development and includes a wide range of case studies. Countries that pioneered various types of community seed banks include Bangladesh, Brazil, Ethiopia, India, Nepal, Nicaragua, the Philippines and Zimbabwe. In the North, a particular type of community seed bank emerged known as a seed-savers network. Such networks were first established in Australia, Canada, the UK and the USA before spreading to other countries. Over time, the number and diversity of seed banks has grown. In Nepal, for example, there are now more than 100 self-described community seed banks whose functions range from pure conservation to commercial seed production. In Brazil, community seed banks operate in various regions of the country. Surprisingly, despite 25 years of history and the rapid growth in number, organizational diversity and geographical coverage of community seed banks, recognition of their roles and contributions has remained scanty. The book reviews their history, evolution, experiences, successes and failures (and reasons why), challenges and prospects. It fills a significant gap in the literature on agricultural biodiversity and conservation, and their contribution to food sovereignty and security.




The Soil Seed Banks of North West Europe


Book Description

Buried viable seed banks are a fundamental aspect of seed plant biology. They play a key role in the conservation and restoration of plant communities and the response of plants to changing land use and climate. There is almost no area of plant ecology in which seed banks are not implicated. Despite several recent reviews of the ecology of seed banks, there has previously been no single source of data on seed persistence in individual species. This volume, which compiles the available data from the nineteenth century up to the end of 1993, provides this source for the 1189 members of the northwest European flora. The text describes the criteria for inclusion of data and discusses seed classification systems, the relative representation of different habitats, methods and taxa, and challenges for future research. Includes PC disc with database in searchable format.




Seeds on Ice: Svalbard and the Global Seed Vault


Book Description

The remarkable story of the Global Seed Vault--and the valiant effort to save the past and the future of agriculture: Now updated with a new chapter by the author and photos from recent improvements in the facilities. Closer to the North Pole than to the Arctic Circle, on an island in a remote Norwegian archipelago, lies a vast global seed bank buried within a frozen mountain. At the end of a 130-meter long tunnel chiseled out of solid stone is a room filled with humanity's precious treasure, the largest and most diverse seed collection ever assembled: more than a half billion seeds containing the world's most prized crops, a safeguard against catastrophic starvation. The Global Seed Vault, a visionary model of international collaboration, is the brainchild of Cary Fowler, renowned scientist, conservationist, and biodiversity advocate. In SEEDS ON ICE, Fowler tells for the first time the comprehensive inside story of how the "doomsday seed vault" came to be, while the breathtaking photographs offer a stunning guided tour not only of the private vault, but of the windswept beauty and majesty of Svalbard and the enchanting community of people in Longyearbyen. With growing evidence that unchecked climate change will seriously undermine food production and threaten the diversity of crops around the world, SEEDS ON ICE offers a personal and passionate reminder that we shouldn't take our reliance on the world of plants for granted--and that, in a very real sense, the future of the human race rides on this frozen and indispensable biodiversity.




Seed Banks


Book Description

This book provides new research in the study on seed banks. Chapter One begins with an overview of seed bank research in Central European grasslands. Chapter Two focuses on the Caucasus Regional Seed Bank (CRSB). Chapter Three discusses Crofton weed invasion history and damages in China, seed characteristics, germination characteristics and light dependence of seed germination. Chapter Four provides a case study review of soil seed bank and rangeland conditions in North Patagonia.

Seeds


Book Description

Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination provides a working hypothesis of the ecological and environmental conditions under which carious kinds of seed dormancy have developed. It also presents the seed germination of morethan 3500 species of trees, shrubs, vines, and herbaceous species.




The Ecology of Seeds


Book Description

What determines the number and size of the seeds produced by a plant? How often should it reproduce them? How often should a plant produce them? Why and how are seeds dispersed, and what are the implications for the diversity and composition of vegetation? These are just some of the questions tackled in this wide-ranging review of the role of seeds in the ecology of plants. The authors bring together information on the ecological aspects of seed biology, starting with a consideration of reproductive strategies in seed plants and progressing through the life cycle, covering seed maturation, dispersal, storage in the soil, dormancy, germination, seedling establishment, and regeneration in the field. The text encompasses a wide range of concepts of general relevance to plant ecology, reflecting the central role that the study of seed ecology has played in elucidating many fundamental aspects of plant community function.




Seed Development and Germination


Book Description

This text is intended for plant physiologists, molecular biologists, biochemists, biotechnologists, geneticists, horticulturalists, agromnomists and botanists, and upper-level undergraduate and graduate students in these disciplines. It integrates advances in the diverse and rapidly-expanding field of seed science, from ecological and demographic aspects of seed production, dispersal and germination, to the molecular biology of seed development. The book offers a broad, multidisciplinary approach that covers both theoretical and applied knowledge.
