Australian acacias are genetically highly diverse across the globe

Australian acacias are some of the world’s worst invasive plants and their success has been heavily shaped through their usage by humans for various purposes. C·I·B research members Prof Jaco Le Roux, Prof Dave Richardson and Prof John Wilson, together with colleagues from the University of Lisbon, published a meta-analysis on the genetic diversity of 37 Australian Acacia species.

C·I·B researcher analyse pathways of biological invasions

Invasions of alien species begin with the human-assisted movement of living individuals or propagules across biogeo­graphic barriers. As a result, the contributions of specific path­ways to introduction and subsequent invasion—and the changes in the importance of pathways over time—are receiving increasing attention from scientists and poli­cymakers.

Developing invasive species watch lists for resource poor nations

Invasive species risk assessments have been developed to identify species that pose an invasion risk. Unfortunately, risk assessments tend to be expensive and time consuming, and due to a lack of resources (data, skills and funding) many resource poor nations cannot implement these tools. For developing nations, a useful alternative approach may be to develop watch lists of invasive species.

Global initiative guide regulations to reduce alien species in Antarctica

Recently published C·I·B research conducted in association with the International Polar Year ‘Aliens in Antarctica’ project has measured the propagule load carried in the clothing and gear of researchers and visitors to the Antarctic region.
