• Rapid response to shoot removal by the invasive wetland plant, alligator weed (Alternanthera philoxeroides) 

      Wilson, J.R.U.; Yeates, A.; Schooler, S.; Julien, M.H. (Elsevier B.V., 2007)
      Resprouting plants provide an interesting test to the generality of plant allometric relationships. The ability to rapidly resprout after disturbance also makes weeds more difficult to control. We performed a glasshouse ...

      Jacobs, L.E.O.; van Wyk, E.; Wilson, J.R.U. (REABIC, 2015)
      The discovery of a naturalised population of Melaleuca quinquenervia in South Africa in 2009 prompted an evaluation of the species’ distribution across South Africa. We found records at seven localities in two of the nine ...
    • Refining the process of agent selection through understanding plant demography and plant response to herbivory 

      Raghu, S.; Wilson, J.R.U.; Dhileepan, K. (2006)
      Understanding plant demography and plant response to herbivory is critical to the selection of effective weed biological control agents. We adopt the metaphor of ‘filters’ to suggest how agent prioritisation may be improved ...

      Novoa, A.; Kaplan, H.; Wilson, J.R.U.; Richardson, D.M. (Springer, 2016)
      The regulation and management of alien species can be contentious, particularly when the stakeholders who benefit from alien species are different from those who suffer the costs. We propose a consultative process involving ...

      Donaldson, J.E.; Richardson, D.M.; Wilson, J.R.U. (Springer, 2014)
      Scale-area curves are increasingly used in ecology to predict population trajectories, based on the assumption that observed patterns are indicative of population dynamics. However, for introduced species, scale-area ...
    • Searching for phylogenetic pattern in biological invasions 

      Proches, S.; Wilson, J.R.U.; Richardson, D.M.; Rejmánek, M. (Blackwell Publishing Ltd, 2008)
      It has been suggested that alien species with close indigenous relatives in the introduced range may have reduced chances of successful establishment and invasion (Darwin’s naturalization hypothesis). Studies trying to ...
    • The seed ecology of an ornamental wattle in South Africa - Why has Acacia elata not invaded a greater area? 

      Donaldson, J.E.; Richardson, D.M.; Wilson, J.R.U. (Elsevier, 2014)
      Australian Acacia species introduced to South Africa as ornamentals have notably smaller invasive ranges than those introduced for forestry or dune stabilization.We asked whether the relatively small invasive extent of ...
    • A simple, rapid methodology for developing invasive species watch lists 

      Faulkner, K.T.; Robertson, M.P.; Rouget, M.; Wilson, J.R.U. (2014-11)
      Biosecurity schemes aim to prevent the introduction of species with a high invasion potential, without unduly restricting personal freedom and commercial activities. But invasive species risk assessments are time consuming, ...
    • Site-specific conditions influence plant naturalization: The case of alien Proteaceae in South Africa 

      Moodley, D.; Geerts, S.; Rebelo, T.; Richardson, D.M.; Wilson, J.R.U. (Elsevier, 2014-08)
      The outcome of plant introductions is often considered in binary terms (invasive or non-invasive). However, most species experience a time lag before naturalization occurs, and many species become naturalized at some sites ...
    • Small urban centres as launching sites for plant invasions in natural areas: insights from South Africa 

      McLean, P.; Gallien, L.; Wilson, J.R.U.; Gaertner, M.; Richardson, D.M. (Springer, 2017)
      Alien species are often first introduced to urban areas, so it is unsurprising that towns and cities are often hotspots for invasions. However, while large cities are usually the first sites of introduction, small towns ...
