First published in 1976, this volume describes the structure and
functioning of grassland ecosystems. Five kinds of grassland are
considered, namely natural temperate grasslands, semi-natural temperate
meadows and pastures, tropical grasslands, arable grassland and
cropland. Descriptions of the abundance and biomass of plants, animals
and micro-organisms are provided, as well as an assessment of the
activities of each functional group of organisms in relation to
production, consumption and decomposition. Static models of energy flow
and nutrient cycling are included, and the effects on the ecosystem of
the management of grazing land and cropland are also considered. The
volume is based on data collected in more than 50 studies made during
the International Biological Programme studies in 22 countries.
