Download or read book Physiological Ecology of North American Plant Communities written by Brain F. Chabot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.

Download or read book Biomass Burning and Its Inter Relationships with the Climate System written by John L. Innes and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: JOHN L. INNES University of British Columbia, Vancouver, Canada The interactions between biomass burning and climate have been brought into focus by a number of recent events. Firstly, the Framework Convention on Climate Change and, more recently, the Kyoto Protocol, have drawn the attention of policy makers and others to the importance of biomass burning in relation to atmospheric carbon dioxide concentrations. Secondly, the use of prescribed fires has become a major management tool in some countries; with for example the area with fuel treatments (which include prescribed burns and mechanical treatments) having increased on US National Forest System lands from 123,000 ha in 1985 to 677,000 ha in 1998. Thirdly, large numbers of forest fires in Indonesia, Brazil, Australia and elsewhere in 1997 and 1998 received unprecedented media attention. Consequently, it is appropriate that one of the Wengen Workshops on Global Change Research be devoted to the relationships between biomass burning and climate. This volume includes many of the papers presented at the workshop, but is also intended to act as a contribution to the state of knowledge on the int- relationships between biomass burning and climate change. Previous volumes on biomass burning (e. g. Goldammer 1990,Levine 1991a, Crutzen and Goldammer 1993, Levine 1996a, 1996b, Van Wilgen et al. 1997) have stressed various aspects of the biomass–climate issue, and provide a history of the development of our understanding of the many complex relationships that are involved.

Download or read book A Eutrophic Lake written by Thomas D. Brock and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Mendota has often been called "the most studied lake in the world. " Beginning in the "classic" period of limnology in the late 19th century and continuing through the present time, this lake has been the subject of a wide variety of studies. Although many of these studies have been published in accessible journals, a significant number have appeared in local monographs and reports, ephemeral documents, or poorly distributed journals. To date, there has been no attempt at a synthetic treatment ofthe vast amount of work that has been published. One intent of the present book is to present a com prehensive compilation of the major early studies on Lake Mendota and to examine how they impinge on important present-day biological questions. In addition, this book presents a summary of field and laboratory work carried out in my own laboratory over a period of about 6 years and shows where correlations with earlier work exist. The book should be ofinterest to limnologists desiring a ready reference to data and published papers on this important lake, to biogeochemists, ocean ographers, and low-temperature geochemists interested in lakes as model sys tems for global processes, and to lake managers interested in understanding short-term and long-term changes in lake systems. Although the major thrust ofthe present book is ecologicaland environmental, sufficient background has been presented on other aspects ofLake Mendota's limnology so that the book should also be useful to nonbiologists.

Download or read book Cyanobacteria in Symbiosis written by A.N. Rai and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyanobacterial symbioses are no longer regarded as mere oddities but as important components of the biosphere, occurring both in terrestrial and aquatic habitats worldwide. It is becoming apparent that they can enter into symbiosis with a wider variety of organisms than hitherto known, and there are many more still to be discovered, particularly in marine environments. The chapters cover cyanobacterial symbioses with plants (algae, bryophytes, Azolla, cycads, Gunnera), cyanobacterial symbioses in marine environments, lichens, Nostoc-Geosiphon (a fungus closely related to arbuscular mycorrhiza fungi) symbiosis, and artificial associations of cyanobacteria with economically important plants. In addition, cyanobiont diversity, sensing-signalling, and evolutionary aspects of the symbiosis are dealt with. Renowned experts actively involved in research on cyanobacterial symbioses deal with ecological, physiological, biochemical, molecular, and applied aspects of all known cyanobacterial symbioses. This volume on cyanobacteria in symbiosis complements the two earlier volumes on cyanobacteria published by Kluwer (Molecular Biology of Cyanobacteria, edited by D.A. Bryant and Ecology of Cyanobacteria, edited by B.A. Whitton and M. Potts). Together, the three volumes provide the most comprehensive treatment of cyanobacterial literature as a whole. The book will serve as a valuable reference work and text for teaching and research in the field of plant-microbe interactions and nitrogen fixation.

Download or read book Arguments for Protected Areas written by Sue Stolton and published by Routledge. This book was released on 2010-08-12 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most protected areas (e.g.national parks and nature reserves) have been created to protect wildlife and land- and seascape values. They currently cover over 13% of the world's land surface, around 12% of marine coastal areas and 4% of the marine shelf. Retaining and expanding these areas in the future will depend on showing their wider benefits for society. This book provides a concise and persuasive overview of the values of protected areas. Contributing authors from over fifty countries examine a wide range of values that are maintained in protected areas, including food, water and materials; health; tourism; cultural and spiritual values; and buffering capacity against climate change and natural disasters. The book also considers the role of protected areas in poverty reduction strategies, their relationship with traditional and indigenous people and in fostering conflict resolution through peace parks initiatives. The chapters draw on a series of authoritative reports published by WWF over recent years under the 'Arguments for Protection' banner, in association with various partners, and on additional research carried out especially for the volume. It analyses the opportunities and limitations of protected areas for supplying the various values along with practical advice for planners and managers about maximising benefits. It provides an important contribution to the debate about the role of protected areas in conservation and other aspects of natural resource management and human livelihoods. Published with WWF

Download or read book A Key for Predicting Postfire Successional Trajectories in Black Spruce Stands of Interior Alaska written by Jill Frances Johnstone and published by . This book was released on 2008 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Black spruce (Picea mariana (Mill) B.S.P) is the dominant forest cover type in interior Alaska and is prone to frequent, stand-replacing wildfires. Through impacts on tree recruitment, the degree of fire consumption of soil organic layers can act as an important determinant of whether black spruce forests regenerate to a forest composition similar to the prefire forest, or to a new forest composition dominated by deciduous hardwoods. Here we present a simple, rule-based framework for predicting fire-initiated changes in forest cover within Alaska's black spruce forests. Four components are presented: (1) a key to classifying potential site moisture, (2) a summary of conditions that favor black spruce self-replacement, (3) a key to predicting postfire forest recovery in recently burned stands, and (4) an appendix of photos to be used as a visual reference tool. This report should be useful to managers in designing fire management actions and predicting the effects of recent and future fires on postfire forest cover in black spruce forests of interior Alaska.
