This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytomass and Primary Production of the Various Vegetational Zones and of the Entire Biosphere The biosphere is that thin layer at the earth's surface in which living organisms exist and biological cycling takes place. It includes the upper horizons of the soil in which plants root, the atmosphere near the ground, (insofar as organisms penetrate this space), and all the surface waters. More than 99% of the earth's biomass is phytomass, to which we shall limit our discussion. Amounts of phytomass are distinctly related to vegeta tional zones. Because accurate determination of phytomass and primary production is difficult, only gross estimates have been available until recently. However, in 1970, Bazilevich et al. published (in Russian) more accurate calculations, based on the rapidly accumulating literature, for the various thermal zones and bioclimatic regions of the earth. These authors calculated mean phyto mass and mean annual primary production for the various regions as dry mass (in tons) per hectare. On the basis of measurements of the areas covered by the individual regions, excluding rivers, lakes, glaciers, and permanent snow, total phytomass and total annual primary production for the various regions were obtained (see table). The sum of these figures is the phytomass and annual production of the land surface of the earth. In addition, the table gives corresponding data for the waters of the earth. The values involved are potential i. e. , they are based on natural vegetation uninfluenced by man.

Download or read book Climate Dynamics of the Tropics written by S. Hastenrath and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of my book "Climate and Circulation of the Tropics" was reasonably up to date to the middle of 1985. In a second printing in 1988 it was possible to complete a few literature references and to correct some misprints. However, vigorous research has taken place over the past five years in various areas of tropical climate dynamics, especially in the atmosphere-ocean mechanisms of climate anomalies, climate prediction, ocean circulation, and paleoclimates. Promising progress has also been made in the application of general circulation modelling to tropical climate problems. In the present second edition, named "Climate Dynamics of the Tropics", I have attempted to incorporate much of the recent work to late 1990. Chapters 8 and 9 have been essentially re-written, and major additions have been made to Chapters 4 and 12 in particular. I would like to acknowledge the continued support by the U.S. National Science Foundation over the past five years. B. Parthasarathy, Poona, and H. Lessmann, San Salvador, sent me updates of data series not easily accessible. I have benefitted from discussions with numerous colleagues in the United States and overseas. In the preparation of this second edition, Marilyn Wolff patiently transferred my illegible hand-written drafts onto word processor. Dierk Polzin and Dan Skemp assisted me with the creation of the page masters and the subject index and Christopher Collimore with the author index.

Available in PDF, EPUB and Kindle. Book excerpt: Large regions of the world are regularly burnt either deliberately or naturally. However, despite the widespread occurrence of such fire-prone ecosystems, and considerable body of research on plant population biology in relation to fire, until now there have only been limited attempts at a coherent conceptual synthesis of the field for use by students or researchers.

Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Download or read book Vegetation history written by B. Huntley and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of vegetation history is one of the prime objectives for vegetation scientists. In order to understand the recent composition of local floras and plant communities a second knowledge of species com position during recent millenia is essential. With the present concern over climate changes, due to human activities, an understanding of past vegeta tion distribution becomes even more important, since the correlation between climate and vegetation can often be used to predict possible impacts to crops and forests. I was very fortunate to receive the help of Drs. Webb and Huntley to compile this volume on vegetation history. They have collated an impres sive set of papers which together give an account of the vegetation history of most of the continents during the late-Tertiary and Quaternery periods. There are, however, gaps in the coverage achieved, most notably Africa, and Asia apart from Japan. The information in this book will nonetheless certainly be used widely by vegetation scientists for the regions covered in the book and much of it has relevance to the areas not explicitly described. The authors of the individual chapters have done their best to cover recent topics of interest as well as established facts. It is intended that a separate volume will be produced in the near future covering the vegetation history of Africa and Asia. I thank the editors of It fits well into the this volume for their commendable achievement.

Available in PDF, EPUB and Kindle. Book excerpt: During the International Botanical Congress in Edinburgh, 1964, Mrs. 1. M. WEISBACH-J UNK of The Hague discussed a plan for preparation by her publishing company (Dr. W. Junk b.v.) of an international Handbook of Vegetation Science. She proposed a series that should give a comprehensive survey of the varied directions within this science, and their achievements to date as well as their objectives for the future. The challenge of such an enterprise, and its evident value for the further development of vegetation research, induced the undersigned after some consideration to accept the offer of the honorable but also burdensome task of General Editor. The decision was encouraged by a well formulated and detailed outline for the Handbook worked out by the Dutch phytosociolo gists J. J. BARKMAN and V. WESTHOFF. A circle of scholars from numerous countries was invited by the Dr. Junk Publishing Com pany to The Hague in January 1966 to draw up a list of editors and contributors for the parts of the Handbook. The outline and list have served since for the organization of the Handbook, with no need for major change. The different burdens of editors and authors have compelled quite different timings for completion of the individual sections.

Available in PDF, EPUB and Kindle. Book excerpt: The understanding and management of land resources used by grazing animals are of major importance to ecologists and agricultural and environmental scientists. This book fills a major gap in the market by synthesising a range of perspectives on grazing systems, drawn from plant science, animal science and ecology. It outlines the principles of herbage growth and competition; of animal nutrition and grazing behavior; and of the interactions of plant and animal factors that are central to an understanding of grazing systems. Chapters on the management of grazing systems cover both intensive and extensive systems (including rangelands) from all major agroecological zones of the world. The book is written by leading authorities from the USA, UK, Australia, New Zealand, South Africa, Israel and France. It represents a major contribution to the literature for advanced students and research workers concerned with plant science (especially grasslands), animal science (especially ruminants), and natural and agricultural ecosystems.
