Performance of invasive alien fountain grass (Pennisetum setaceum) along a climatic gradient through three South African biomes
(Elsevier B.V., 2014-03)
The knowledge of relative performance of plants across environmental gradients is critical for their effective management and for understanding future range expansion. Pennisetum setaceum is an invasive perennial grass ...
The effectiveness of active and passive restoration on recovery of indigenous vegetation in riparian zones in the Western Cape, South Africa: A preliminary assessment
Riparian ecosystems in South Africa's fynbos biome are heavily invaded by alien woody plants. Although largescale clearing of these species is underway, the assumption that native vegetation will self-repair after ...
Potential seed dispersal distances of native and non-native fleshy fruiting shrubs in the South African Mediterranean Climate Region
Bird flight distances for the small Zosterops capensis, the medium-size Pycnonotus capensis and the large Colius striatus were extracted from these birds’ initial ring and subsequent recapture locations and expressed on ...
Competitive interactions between the alien invasive annual grass Avena fatua and indigenous herbaceous plants in South African Renosterveld: the role of nitrogen enrichment
(Springer Science+Business Media B.V., 2010)
Nitrogen enrichment may play a role in successful invasion of indigenous South African mediterranean shrublands by alien invasive annual grasses. To test the hypothesis that an increase in nitrogen would result in a greater ...
Effects of intraspecific and community density on the lifetime fecundity of long-lived shrubs
Intra- and interspecific density dependence has profound consequences for plant population and community dynamics. In long-lived plants, however, lifetime patterns and mechanisms of density dependence are difficult to ...
