| Zusammenfassung: | A selection of major floristic communities from a transect across the equatorial catenary-mosaic vegetation complex is analysed structurally and in an ecological context. In addition to the cover-dominance of general vegetation growth forms (bush, tree, grass, forb), other aspects of the vegetation structure (leaf size, tallness) respond in a recognisable, repetitive way to soil type and topographic variation. However, the major role in dictating both floristic and general structural trends appears to be played by combinations of edaphic and climatic factors. Three major structural complexes are recognised: a) Anogeissus Woodland/Grass-woodland communities dominated by the tallest height class and the medium leaf size classes; b) Terminalia and/or lsoberlinia Grass-woodland communities well represented in all height and leaf size classes; and c) Grewia and Hyparrhenia Grassland/Grass-bushland communities dominated by medium and short height classes, and medium and large leaf classes. |
