Download or read book The Function of Seed Banks in Northern Forest Ecosystems written by Steven C. Hills and published by Sault Ste. Marie : Ontario, Ministry of Natural Resources. This book was released on 1992 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of seeds remaining dormant within the soil is well known and documented but detailed information on the role of such seed banks in northern Ontario is very limited. Research is required to determine the species and abundance of seeds in the soil across a range of forest types, as well as to determine the function of the seed bank in post-disturbance vegetation dynamics. This report presents comparison tables of seed density and diversity for the boreal and deciduous forest types, and discusses the research that has been conducted. The review included detailed discussions of seed bank dynamics, physiology of seeds in a seed bank, boreal and deciduous forest seed banks, seed bank dynamics and succession, and recommendations for initiating a seed bank study in northern Ontario.

Download or read book Community Seed Banks written by Ronnie Vernooy and published by Routledge. This book was released on 2015-05-15 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Synopsis of Information on White Engelmann and Black Spruce Natural Regeneration in North America written by Everett B. Peterson and published by . This book was released on 1994 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report providing a subjective assessment of the scope, applicability, and overall reliability of existing published references related to natural regeneration of white, Engelmann, and black spruce in North America and a synopsis of references on the subject. The references are listed alphabetically by author for each of 563 references, based on a dBASE IV database coded according to 105 keywords. The database allows the user to search geographically, by species of spruce, by forest section within Canada, or by any of the keywords listed. The emphasis is on white spruce in a boreal mixedwood setting but also includes information on natural regeneration of Engelmann spruce and upland black spruce, plus a limited amount of Norway spruce. Most of the references are from the 1990s.
Download or read book Ecosystem Management in the Boreal Forest written by Sylvie Gauthier and published by PUQ. This book was released on 2009 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Ecosystem Management. A management approach that aims to maintain healthy and resilient forest ecosystems by focusing on a reduction of differences between natural and managed landscapes to ensure long-term maintenance of ecosystem functions and thereby retain the social and economic benefits they provide to society.That is the definition of forest ecosystem management proposed in this book, which provides a summary of key ecological concepts supporting this approach. The book includes a review of major disturbance regimes that shape the natural dynamics of the boreal forest and gives examples from different Canadian boreal regions. Several projects implementing the forest ecosystem management approach are presented to illustrate the challenges created by current forestry practices and the solutions that this new approach can provide. In short, knowledge and understanding of forest dynamics can serve as a guide for forest management. Planning interventions based on natural dynamics can facilitate reconciliation between forest harvesting needs and the interests of other forest users.

Download or read book Ecology of Soil Seed Banks written by Mary Allessio Leck and published by Elsevier. This book was released on 2012-12-02 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Fire and Climatic Change in Temperate Ecosystems of the Western Americas written by Thomas T. Veblen and published by Springer Science & Business Media. This book was released on 2006-05-10 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.
