Being an efficient dispersal vector in birds

A recent study by Thabiso Mokotjomela (Research Fellow, University of the Witwatersrand) and colleagues at the C·I·B (core team members Karen Esler & Colleen Downs) found that a few garden birds, such as the red-winged starlings can help the spread of alien invasive plants.

New approaches to compile “100 of the worst” lists

A recent paper by Sabrina Kumschick, C·I·B Core Team Member, together with C·I·B Director Dave Richardson and C·I·B Associate Tim Blackburn investigated whether the birds on the “100 worst” lists are indeed worthy of this honour.

Study shows invasive species can have cross-ecosystem impacts

A recent study by C·I·B post-doctoral fellow, Michelle Jackson, found that invasive species can have effects that reach across different ecosystems.
