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.

Vegetation, soil and climate are the most important components of ecological systems. This long-awaited fourth edition of the well-established textbook by Heinrich Walter summarizes our knowledge of the earth's ecology and constitutes the basis for a deeper understanding of the larger interrelations on a global scale. While Walter's general concept remains unchanged, the individual chapters have been completely revised, enlarged and updated. The author's intimate knowledge of practically all classes of plants and climatic zones allows him to describe the various ecological systems in close detail. This richly illustrated textbook is a must for every student in the plant sciences.

Vegetation, soil and climate are the most important components of ecological systems. The book presents a compact synthesis of our current knowledge of the ecology of the Earth and is thus the basis for understanding the major interrelationships in a global perspective. In the first part, with a rich endowment of illustrations and photographic material, the well-introduced book deals with the essential processes and operations on the Earth's surface that lead to the formation of the vegetation cover with its distinctive zonation. In the second part, the individual vegetation zones as large-scale ecosystems (i.e. zonobiomes of the biosphere) are consistently described comparatively according to certain criteria. In a short and compact form, the main characteristics and structures as well as examples of ecosystem processes are discussed. The large-scale ecosystems are also the basis and reference system for all anthropogenic changes that have drastically altered vegetation over the last millennia, but especially in the 20th century. This book is a translation of the original German 1st edition Vegetation und Klima by Siegmar-W. Breckle and M. Daud Rafiqpoor, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2019. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors. Authors Siegmar-W. Breckle long-time professor and head of the Department of Ecology at the University of Bielefeld (Germany). He continued the multi-volume work "Ecology of the Earth" by Heinrich Walter, published numerous articles and books on the ecology of many regions, especially the drylands combined with countless study trips around the globe. His research in deserts, tropics and high mountains is the basis for the corresponding chapters in this book. M. Daud Rafiqpoor, long-time research associate of the Academy of Sciences and Literature in Mainz and coordinator of two ecologically oriented long-term projects of this academy ("Three-dimensional Landscape Classification of the Tropics and Subtropics" and "Biodiversity in Change"). Numerous study trips in almost all tropical and subtropical mountains of the world. Publication of many papers and books on the geography and ecology of tropical and subtropical high mountains and Afghanistan.

By the end of the last century, the only region in all of Europe where the natural vegetation remained untouched over large expanses was Eastern Europe. Information on the vegetation of this region however, remained mostly unavailable to western scientists although the ecological approach to botanical research originated in Eastern Europe. Heinrich Walter was born in Russia, studied Natural Sciences - with emphasis on botany - in Odessa and is familiar with all relevant Russian literature on ecology. This volume thus offers scientists worldwide a unique and comprehensive survey of all relevant research, including the mostly unknown literature published in Russian.

Twenty-nine, prominent, international researchers provide contributions which deal with understanding the basic ecophysiological and molecular principles governing the functioning of plant systems in relation to their environment. Divided into two headings: biotic and abiotic; the first consists of abiotic, natural environmental factors--light, ultraviolet radiation, chilling and freezing, high temperatures, drought, flooding, salt and trace metals. The latter half presents anthropogenic aspects including allelochemicals, herbicides, polyamines, air pollutants, carbon dioxide, radioisotopes and fire.

In Volume 1 of this four-volume series, ecological problems of a general nature were discussed from a global point of view. Familiarity with this is essential for a full understanding of the more specialized treatment in this and subsequent volumes, for no similar approach is to be found in other ecological handbooks for beginners. This present volume deals in detail with the special ecological relation ships of the tropical and subtropical zonobiomes I to III. Most ecologists proceed from the basis of their experience in the temperate zones of the northern hemisphere. As a result, many ecological writings show a certain one-sidedness and there is a danger that generalizations made will not be broadly applicable. To avoid this, particular emphasis is laid, in this vol urne, on the special ecological features and the characteristics of the trop ical and subtropical regions. More specifically, we deal not only with the relationship of the euclimatope to zonal soils and zonal vegetation, but also pay attention to azonal conditions shown in pedobiomes and in the altitudinal belts of mountains, the orobiomes. In this and the subsequent volumes the same simple scheme is followed in treating each zonobiome: 1. climate; 2. soils; 3. producers; 4. consum ers; 5. decomposers; 6. ecosystems; 7. sub division into biomes; 8. oro biomes; 9. pedobiomes and 10. zonoecotones. Where it has appeared expedient, however, we have occasionally deviated from this scheme (see Deserts D, F, G and H).
