Who we are

The C·I·B is an inter-institutional Centre of Excellence established in 2004 within the DST-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.

The C·I·B has its physical home at the University of Stellenbosch, but comprises a network of senior researchers and their associated postdoctoral associates and graduate students throughout South Africa. Find out more about us.

Mutualisms — fundamental mediators of biological invasions

Potential effects of biological invasions on different types of mutualisms...

Mutualisms are relationships between organisms of different species in which each individual benefits from the activity of the other. These relationships are hugely important in nature. Essential services provided by mutualists include pollination, seed dispersal and the constitution of global cycles of carbon and other nutrients.

Front cover of Plant Invasions in Protected Areas: Patterns, Problems and Challenges

Plant Invasions in Protected Areas: Patterns, Problems and Challenges

by Llewellyn C. Foxcroft, Petr Pyšek, David M. Richardson and Piero Genovesi.

The topic of plant invasions in protected areas is dealt with comprehensively in a new book edited by researchers at the Centre for Invasion Biology (C·I·B), SANParks, the Academy of Sciences of the Czech Republic, Charles University in Prague and the IUCN's Invasive Species Specialist Group. The book provides a global review of all aspects of alien plant invasions in protected areas.

For Students

Rose-ringed parakeets (Psittacula krameri) are the most invasive parrot species in the world and have already invaded 35 countries on five continents. In South Africa, the first sightings were noted in the 1970ís with strongholds predominantly in Gauteng and KwaZulu-Natal. Today populations are also known in Cape Town, and Steytlerville in the Eastern Cape.

There are very few, if any, ecosystems on Earth that are not substantially influenced by human activities. In most ecosystems, humans have changed many abiotic and biotic components, for example by changing disturbance or nutrient regimes and by adding or removing species.

Invasive alien plant control is an expensive exercise. Traditional control strategies, namely mechanical as well as chemical control and use of fire, are particularly expensive and require re-investment over time.
