    • Border control for stowaway alien species should be prioritised based on variations in establishment debt 

      Faulkner, K.T.; Robertson, M.P.; Rouget, M.; Wilson, J.R.U. (Elsevier Ltd, 2016)
      Border control is one of the major approaches used by countries to limit the number of organisms introduced as stowaways. However, it is not feasible to inspect all passengers, cargo and vehicles entering a country, and ...

    • Casuarina: biogeography and ecology of an important tree genus in a changing world 

      Potgieter, L.J.; Richardson, D.M.; Wilson, J.R.U. (Springer, 2014)
      Important insights on the invasion ecology of woody plants are emerging from the study of model groups, but it is important to test how widely such results can be generalised. We examined whether drivers of introduction ...

    • Changes in the composition and distribution of alien plants in South Africa: An update from the Southern African Plant Invaders Atlas 

      Henderson, L.; Wilson, J.R.U. (AOSIS, 2017)

    • The Chilean black urchin, Tetrapygus niger (Molina, 1782) in South Africa: gone but not forgotten 

      Mabin, C.A.; Wilson, J.R.U.; Robinson, T.B. (REABIC, 2015)
      It is important to keep lists of invasive and alien species up to date, but it can be difficult to determine when species should be removed from such lists. One such example is the urchin, Tetrapygus niger (Molina, 1782), ...

    • Co-invasion of South African ecosystems by an Australian legume and its rhizobial symbionts
