Understanding Nassella invasions in South Africa

Urgent research is needed to guide more effective control measures for Nassella grass invasions in South Africa. This was the finding of an extensive literature review by C·I·B-funded PhD student Anthony Mapaura, with inputs from researchers at the Centre for Biological Control at Rhodes University and the University of the Free State’s Qwaqwa campus, and C·I·B Director Dave Richardson.

Scientists propose global guidelines for the sustainable use of non-native trees to protect biodiversity

A team of international scientists, including several with current or previous affiliations with the Centre for Invasion Biology (C∙I∙B), have collaborated to propose a series of global guidelines for the sustainable use of non-native tree species to help protect biodiversity and ecosystems around the world already threatened by climate change.

The invasion continues: Alien species expected to increase by 36% until 2050

Compared to the year 2005, the number of alien species is expected to increase by 36% by the middle of this century. The majority of these newcomers are insects. These are the results of a study by an international team of researchers led by Dr Hanno Seebens of the Senckenberg Biodiversity and Climate Research Center in Germany.
