Steppe ecosystems refers to a biome region characterised by grassland plains without trees apart from those near rivers and lakes. This book presents topical research data in the study of steppe ecosystems, including hydrological conditions of soils and subsoils in the steppe zone of the European part of Russia; the vegetation and pollen-assemblage representations in the southernmost South American steppes; rangeland improvement and management options in the arid steppes of Algeria; water interactions between bare soil and vegetation in semiarid Mediterranean steppes and the effects of grazing pressure on steppe vegetation.
