Plant Invasions: The Role of Biotic Interactions

We are the Centre for Invasion Biology

The C·I·B is an inter-institutional Centre of Excellence established in 2004 within the DSI-NRF Centres of Excellence Programme. Its members undertake research on the biodiversity consequences of biological invasions, largely through post-graduate student training. The principal aims of the Centre’s work are to reduce the rates and impacts of biological invasions by furthering scientific understanding and predictive capability, and by developing research capacity. Find out more about us.

Our Research

We investigate how biological diversity is altered by invasive plants and animals, and the effects these have on the functioning of ecosystems and the services they deliver.

For Students

In support of our vision, we train and guide students who are studying towards an Honours, Masters or Doctoral degree in biodiversity, environmental sociology or invasion biology.

Alien scarlet bottlebrush makes itself at home on Devils Peak

C∙I∙B student, Chelsey Matthys, and C∙I∙B Associate, Sjirk Geerts (based at Cape Peninsula University of Technology), together with colleagues documented the first detailed assessment of the distribution and invasive potential of scarlet bottlebrush (Melaleuca rugulosa) in South Africa.

Generation of machine-learning training samples using traditional image classification algorithms

The study by PhD student, Madodomzi Mafanya, and C∙I∙B Core Team member, Tsungai Zengeya, demonstrated that it is possible to generate large numbers of accurate training samples from traditional image classification algorithms that can be used to map the distribution of alien plant species using machine-learning algorithms.

The dual purpose of Guava invasion in Vhembe Biosphere Reserve

A new study by C∙I∙B Core Team member Sheunesu Ruwanza and co-author Gladman Thondhlana assessed the perceptions, knowledge, and uses of guava to rural communities in the Vhembe Biosphere Reserve, South Africa.

Using wet and dry plants to understand riverbank flooding

A group, including C∙I∙B researchers, have developed a method that uses plant communities to determine the position of the 1:2 year flood line on Fynbos rivers that lack hydrological records.

Invasive crayfish can cause high fisheries damage

A study by C∙I∙B Research Associate Josie South and scientists from SAIAB quantified the ecological damage and potential economic losses caused by two invasive crayfish in southern Africa.

Invasion biology is the study of both the species that become invasive in a system and their impacts on the system they have invaded, as well as the remediation of such invasions.

Unmitigated economic impact of polyphagous shot hole borer estimated at R275 billion

Unmitigated economic impact of polyphagous shot hole borer estimated at R275 billion

The potential economic impact of the polyphagous shot hole borer in South Africa amounts to R275 billion over the next ten years if nothing is done to stem the tide. This estimate is the result of a study conducted by economists and ecologists at the Stellenbosch University (SU) and the University of Pretoria (UP).
