Invasive Nile tilapia Oreochromis niloticus (Linnaeus, 1758) in the Limpopo River system, South Africa: conservation implications
In most tropical river systems there has been a lack of integrated ecological research to investigate the dynamics and impacts of invasive species on recipient river systems. This is in sharp contrast to temperate river ...
Biogeographical insights from ecotones and phytogeographic regions in southern Africa: case studies on invertebrates and alien plants
This thesis addresses questions within the research fields of invasion biology and spatial ecology, with a focus on species distribution patterns, biogeographical regions and ecological transition zones, or ecotones. More ...
The extent, impacts and management of ungulate translocations
The worldwide movement of biota is of substantial concern for the conservation of biodiversity. The movement of species takes place at three different scales. These are translocations of indigenous species within their ...
Consequences of self-fertilisation for fecundity and progency performance in invasive plants
Plants that can self-fertilise should, on average, be more invasive than plants that can not self-fertilise because they can reproduce regardless of the availability of mates and pollinators. Self-fertilisation should have ...
Physiological tolerances and future distributions of two malaria vectors, Anopheles arabiensis and Anopheles funestus
Data collected was for two African malaria vectors, Anopheles arabiensis and Anopheles funestus. It includes information on thermal tolerance variables (CT and LT data) and information on development rate temperature ...
On the implementation effectiveness and efficiency of ecological interventions in operational contexts : the case of Working for Water
This data set was developed to estimate the factors that best predict the cost-effectiveness of Working for Water treatments in the Kouga and Krom project areas. See thesis and publication for details about the study.
The invasive ant Pheidole megacephala on an oceanic island: impact, control and community-level response to management
Alien invasive species are among the most important global conservation threats. Their management is one of the key conservation challenges that will have to be addressed in the next few decades. The study of real invasions ...
