DOWNLOAD EBOOK →Gegenstand des vorliegenden Buchs ist die Pflanzendecke der Erde, wobei neben einer knapp gehaltenen Beschreibung der Vegetationstypen vor allem die kausalen Zusammenhänge zwischen dem Wuchsort charakteristischer (repräsentativer) Pflanzenarten und Pflanzengemeinschaften einerseits und entwicklungsgeschichtlich-historischen, zeitlichen bzw. räumlichen, ökophysiologischen sowie anthropogenen Bedingungen andererseits vermittelt werden. Zwar liegt der Schwerpunkt auf der vom Menschen nicht oder wenig beeinflussten „naturbetonten“ Pflanzendecke; berücksichtigt wird aber auch die „kulturbetonte“ Vegetation, die in klimatisch bzw. edaphisch begünstigten Regionen heute den größeren Flächenanteil einnimmt. Nach einem einführenden Kapitel, das die Grundlagen für die vegetationsökologische Gliederung der Erdoberfläche enthält, werden die Lebensbedingungen der zonalen, extrazonalen und azonalen Vegetation des Flachlands und der Gebirge von den äquatornahen immerfeuchten Tropen bis zu den Polargebieten dargestellt und mit vielen Tabellen, farbigen Graphiken und zahlreichen Fotos illustriert. Kastentexte bieten darüber hinaus ergänzende Informationen zu Spezialthemen. Ein umfangreiches Literaturverzeichnis erleichtert den Zugang zu vertiefenden Publikationen.

DOWNLOAD EBOOK →This up-to-date textbook of global vegetation ecology, which comprises the current state of knowledge, is long overdue and much-needed. It is a translation of the textbook “Vegetation der Erde” (Springer-Spektrum, Heidelberg). A short introductory chapter deals with the fundamentals of vegetation ecology that are of importance for the delimitation and characterization of the global vegetation presented in this book (chorology, evolution of plants, physiognomic and structural characteristics, phytodiversity and the human impact on it as well as general terminology concerning both plant growth forms and on vegetation structure types). In the following chapters the zonal and azonal vegetation from the tropics to the polar regions including high mountains is described and discussed. The main focus is on the characterization of interactions between the spatial location of plants and plant communities on the one hand and site conditions, historic and genetic processes, spatial and temporal patterns, ecophysiology and anthropogenic influences on the other hand. Additional information on specific topics is provided in 51 boxes.

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.
