Guidelines for improved management of riparian zones invaded by alien plants in South Africa
(Elsevier B.V., 2008)
This paper reviews the results of recent research on riparian vegetation recovery following the clearance of invasive alien plants. In Fynbos, Grassland and Savanna Biomes, riparian ecosystems were found to have relatively-high ...
Alien plant invasions—incorporating emerging invaders in regional prioritization: A pragmatic approach for Southern Africa
Plant invasions are a serious threat to natural and semi-natural ecosystems worldwide. Most management-orientated research on invasions focuses on invaders that are already widespread and often have major impacts. This ...
Geographical and taxonomic biases in invasion ecology
(Elsevier Ltd., 2008)
Invasive alien species come from most taxonomic groups, and invasion biology is searching for robust cross-taxon generalizations and principles. An analysis of 2670 papers dealing with 892 invasive species showed that all ...
Alien conifer invasions in South America: short fuse burning?
(Springer Science+Business Media B.V., 2008)
Alien conifers have been widely planted in the Southern Hemisphere. Australia, New Zealand and South Africa, all with long histories of alien conifer planting, have major problems with invasive conifers (‘‘wildings’’). ...
Invasion biology deconstructed

Dissecting the plant–insect diversity relationship in the Cape
It has been argued that insect diversity in the Cape is disproportionately low, considering the unusually high plant diversity in this region. Recent studies have shown that this is not the case, but the precise mechanisms ...
The (bio)diversity of science reflects the interests of society
For ecologists to develop robust generalizations and principles, a broad taxonomic and geographic spread of research is required, but, in practice, most generalizations are based on the research of individual scientists ...
Can riparian seed banks initiate restoration after alien plant invasion? Evidence from the Western Cape, South Africa
(Elsevier B.V, 2008)
Riparian zones are complex disturbance-mediated systems that are highly susceptible to invasion by alien plants. They are prioritized in most alien-plant management initiatives in South Africa. The current practice for the ...
Riparian vegetation management in landscapes invaded by alien plants: Insights from South Africa
(Elsevier B.V., 2008-01-31)
Functional group identity does not predict invader impacts: differential effects of nitrogen-fixing exotic plants on ecosystem function
(SPRINGER, VAN GODEWIJCKSTRAAT, 2007-03)
The introduction of exotic plants can have large impacts on ecosystem functions such as soil nutrient cycling. Since these impacts result from differences in traits between the exotic and resident species, novel physiological ...
