What variables should be monitored to aid the management of invasive species? Applying the concept of essential biodiversity variables, a new study identified three essential variables for invasion monitoring; alien species occurrence, status and impact.
Two biological control agents maintain the potential to be effective agents against bugweed, after the incorporation of plant ecophysiology and climatic modelling in the assessment of their effectiveness.
A recent study, led by C·I·B Post-doc Ana Nunes, highlights the danger of an invasive freshwater crayfish reaching the Okavango Delta and the potential devastating consequences for the ecology of this UNESCO World Heritage Site.
A recent study by C·I·B Associate, Sjirk Geerts (based at Cape Peninsula University of Technology), together with researchers from the C·I·B, SANBI’s Invasive Species Programme and the University of Cape Town, stressed the importance of human activities in the spread of some of the most notorious plant invaders.
A new protocol for identifying and categorising the environmental impacts of alien species may help invasion biologists to complete a global stocktake on the environmental impacts of all known alien species by 2020.
