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.

Available in PDF, EPUB and Kindle. Book excerpt: The legacy of Alexander von Humboldt (1769–1859) looms large over the natural sciences. His 1799–1804 research expedition to Central and South America with botanist Aimé Bonpland set the course for the great scientific surveys of the nineteenth century, and inspired such essayists and artists as Emerson, Goethe, Thoreau, Poe, and Church. The chronicles of the expedition were published in Paris after Humboldt’s return, and first among them was the 1807 “Essay on the Geography of Plants.” Among the most cited writings in natural history, after the works of Darwin and Wallace, this work appears here for the first time in a complete English-language translation. Covering far more than its title implies, it represents the first articulation of an integrative “science of the earth, ” encompassing most of today’s environmental sciences. Ecologist Stephen T. Jackson introduces the treatise and explains its enduring significance two centuries after its publication.

This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: We shall limit our observations to the conditions in natural ecosystems, since it would be beyond the scope of this book to embark upon a consideration of secondary, man-made ecosystems. 2. Classification of the Geo-biosphere into Zonobiomes The biosphere is the thin layer of the earth's surface to which the phenomena connected with living matter are confined. On land, this comprises the lowest layer of the atmosphere permanently inhabited by living organisms and into which plants extend, as well as the root-containing portion of the lithosphere, which we term the soil. Living organisms are also found in all bodies of water, to the very depths of the oceans. In a watery medium, however, cycling of material is achieved by means other than those on land, and the organisms (plankton) are so different that aquatic ecosystems have to be dealt with separately. The biosphere is therefore subdivided into (a) the geo-biosphere comprising terrestrial ecosystems, and (b) the hydro-biosphere, comprising aquatic ecosystems, which is the field of hydrobiologists (oceanographers and limnologists) . Our studies are confined to the geo-biosphere (Walter 1976), which constitutes the habitat of man and is, therefore, of special interest. The prevailing climate, being the primary independent factor in the environment, can be used as a basis for further subdivision of the geo-biosphere since the formation of soil and type of vegetation are dependent upon it (see p. 3), and it has not yet been substantially influenced by man.

Download or read book Plant and Vegetation Mapping written by Franco Pedrotti and published by Springer Science & Business Media. This book was released on 2012-08-16 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is concerned principally with geobotanical mapping. Geobotany is a broad science that deals with the study of species and of vegetation communities in relation to the environment; it includes other, perhaps more familiar sciences, such as plant geography, plant ecology, and chorology, and phytosociology (plant sociology). Geobotanical cartography is a field of thematic cartography that deals with the interpretation and representation, in the form of maps, of those spatial and temporal phenomena that pertain to flora, vegetation, vegetated landscapes, vegetation zones, and phytogeographical units. The production of a geobotanical map represents the last stage in a cognitive process that begins with observations in the field and continues with the collection of sample data, interpretation of the phenomena observed, and their appropriate cartographic representation; geobotanical cartography is closely tied to the concepts and scope of geobotany in general

Download or read book Plant Geography written by Martin Kellman and published by Taylor & Francis. This book was released on 2023-04-01 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1975 and in a second edition in 1980, Plant Geography was the first text in biogeography that provided an adequate treatment of modern plant population theory. It is an introduction to the subject for students of both geography and biology. The author develops a series of plant geographic concepts that are based primarily in plant population biology, treating in turn processes that operate at the level of the individual plant and the plant population; interactions between plant populations; environmental conditions and plant dissemination in shaping plant species’ distributions, and the geography of vegetation. Emphasis throughout is placed upon the dynamic nature of the earth’s plant cover, and the interplay between contemporary conditions and historical events in shaping plant distributions and evolution.

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.

Download or read book Plants and Vegetation written by Paul Keddy and published by Cambridge University Press. This book was released on 2007-06-07 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants make up 99.9 percent of the world's living matter, provide food and shelter, and control the Earth's climate. The study of plant ecology is therefore essential to understanding the biological functions and processes of the biosphere. This vibrant introductory textbook integrates important classical themes with recent ideas, models and data. The book begins with the origin of plants and their role in creating the biosphere as the context for discussing plant functional types and evolutionary patterns. The coverage continues logically through the exploration of causation with chapters, amongst others, on resources, stress, competition, predation, and mutualism. The book concludes with a chapter on conservation, addressing the concern that as many as one-third of all plant species are at risk of extinction. Each chapter is enriched with striking and unusual examples of plants (e.g., stone plants, carnivorous plants) and plant habitats (e.g., isolated tropical tepui, arctic cliffs). Paul Keddy writes in a lively and thought-provoking style which will appeal to students at all levels.

Download or read book Forests And Forest Plants Volume I written by John N. Owens and published by EOLSS Publications. This book was released on 2009-02-24 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests and Forest Plants is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Forests are an essential part of Earth's life support systems. Forest resources are essential for humankind. They provide both vital goods and services. They provide food, fuel, shelter, soil and water protection, and filter the air we breathe. This publication on Forest and Forest Plants provides the user with such information as to create an awareness of the value of our forestlands and the products and environmental services they provide. The three volumes on Forests and Forest Plants are organized starting with first the necessity of : the World's Forest Resources – including classification and distribution of forest, urban forestry and agroforestry; Important Tree Species including trees in reclamation and arid zone forestry; Forests and Forest Products including wood and non word products; the Role of Forests in the Biosphere – preserving biological diversity, functions in the hydrological cycle, etc.; and Conservation and Breeding of Forest Trees – what is being done to improve our forest resources - silviculture, tree nurseries, and forest protection. The theme Forest and Forest Plants has led to the conclusion that there are substantial difficulties in matching environmental concerns and sustainability with an ever-increasing world population. Thus there is a tension between maximizing for food, wood and production on the one hand and implementing sustainable development and environmental protection on the other. These three volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, plant biology is considered from the perspective of plants and their surrounding environment, including both biotic and abiotic interactions. The intended audience is undergraduate students in the middle or final phases of their programs of study. Topics are developed to provide a rudimentary understanding of how plant-environment interactions span multiple spatiotemporal scales, and how this rudimentary knowledge can be applied to understand the causes of ecosystem vulnerabilities in the face of global climate change and expansion of natural resource use by human societies. In all chapters connections are made from smaller to larger scales of ecological organization, providing a foundation for understanding plant ecology. Where relevant, environmental threats to ecological systems are identified and future research needs are discussed. As future generations take on the responsibility for managing ecosystem goods and services, one of the most effective resources that can be passed on is accumulated knowledge of how organisms, populations, species, communities and ecosystems function and interact across scales of organization. This book is intended to provide some of that knowledge, and hopefully provide those generations with the ability to avoid some of the catastrophic environmental mistakes that prior generations have made.
