The CABI-published book is the first to focus on the key role of species interactions in mediating invasions.

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.

Invasive Banksia attracts pollinators away from native Bot River protea

A recent paper, co-authored by C∙I∙B Associate Prof Sjirk Geerts, revealed how an invasive flowering plant competes with native plants for pollinators and how this influence seed production in native species.

Visual recognition and coevolutionary history drive responses of amphibians to an invasive predator

A recent study by a research team, including C∙I∙B post-doc Andrea Melotto, examined the responses of larvae from amphibian species to an invasive predator.

Trout impact on distributional patterns of native fish species

A recent fish survey by C∙I∙B members in the headwaters of the Blyde River, Mpumalanga Province, revealed that Rainbow trout (Oncorhynchus mykiss) invasions have reduced the abundance and divided the community structure of native fish species.

Urban toads show themselves to be bolder – before and after invasion

Many of us are now familiar with urban commensal species - those that have adapted to life in towns and cities and can be seen to adapt their behaviour to exploit their new surroundings. Some of these urbanised species are then introduced to novel systems, and go on to become invasive.

Impacts of invasive alien species in South Africa reviewed

A review of the peer-reviewed literature was undertaken at the Centre for Invasion Biology (C·I·B) to determine the level of understanding of the impacts of invasions of all taxonomic groups in all natural and semi-natural ecosystems in South 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.

What informs decisions to manage urban biological invasions?

What informs decisions to manage urban biological invasions?

Urban areas are foci for the introduction of alien species and very often act as launching sites for invasions into natural ecosystems that adjoin urban ecosystems. Until very recently, the study of biological invasions has focused on developing concepts and frameworks mainly for (semi)natural ecosystems.
