Flower-feeding weevils: a long-term solution to Bugweed?

A paper published in the journal Biological Control showed that flower-feeding weevils can be effective biocontrol agents by reducing the number of flowers, fruits and seeds that the invasive tree Bugweed (Solanum mauritianum) produce.

What’s your name? Resolving taxonomic uncertainties in an invasive tree

A recent paper led by C·I·B post-doctoral fellow Heidi Hirsch highlights how uncertainty about the taxonomy can impact inferences in invasion ecology, using the Australian silver wattle (Acacia dealbata) as a case study.

C∙I∙B members collaborate to build capacity in river rehabilitation monitoring

Habitat modification, pollution and alien fishes are among the greatest threats to South Africa’s freshwater biodiversity. Alien fish impact is primarily through predation on, and/or competition with, native fishes, invertebrate and plant communities.

Negative effects of Siam weed invasions for Tanzanian livelihoods

Findings from a paper by a C·I·B post-doctoral fellow, Ross Shackleton, highlight how a recent invader, Siam weed (Chromolaena odorara), has significant negative impacts on the livelihoods of local communities and the environment in Tanzania.

Bridging the knowing-doing gap in Blaauwberg Nature Reserve

In November 2016, the Centre for Invasion Biology (C·I·B) supported a workshop to help close the gap between research and management practices in the restoration of Cape Flats Sand Fynbos.
