Effective management of grazers requires understanding of the mechanisms influencing population declines. Roan antelope, a specialist grazer, has declined in population numbers within Kruger National Park, South Africa. The most widely accepted hypot

Semi arid rivers are subject to highly variable flow regimes as a result of strongly seasonal and unpredictable rainfall. Riparian landscape state changes resulting from a prolonged low flow period followed by a high magnitude flood were examined in

Potamogeton crispus L. grows as a winter producing annual in the shallow lakes of the Pongolo Floodplain, South Africa. Colonization of leaves by algal and bacterial epiphytes, as seen by scanning electron microscopy, followed the established pattern

CD4+ and CD8+ alpha/beta+ T cells of the T helper cell (Th)2 phenotype produce the cytokines IL-4, IL-5, and IL-13 that promote IgE production and eosinophilic inflammation. IL-4 may play an important role in mediating the differentiation of antigeni

Summary The envisaged construction of a dam on a major tributary of the Nyl River will alter the hydrological regime with consequent effects on the structure and functioning of the downstream floodplain ecosystem (Nylsvley). Attempts to minimise this

Many water bodies in arid southern Africa are seasonal and waterfowl habitats become restricted during the dry winters. Nevertheless, some tropical species, such as the white-faced duck, are expanding their ranges into more temperate regions where su

The Pongolo River floodplain supports large populations of waterfowl which feed on the vegetative structures of the submerged plant Potamogeton crispus. Maintenance of a stable grazing system is contingent upon the plants having specific life history
