    The European shore-crab Carcinus maenas has been present in South Africa since 1983. Despite this species’ international reputation as a biological invader, its distribution in this region has only been considered by three ...
  • Non-native species in urban environments: patterns, processes, impacts and challenges 

    Gaertner, M.; Wilson, J.R.U.; Cadotte, M.W.; MacIvor, J.S; Zenni, R.D.; Richardson, D.M. (Springer, 2017)
    Although urban ecosystems are hotspots for biological invasions, the field of invasion science has given scant attention to invasion dynamics and the challenges facing managers in towns and cities. This paper provides ...
  • How do invasive species travel to and through urban environments? 

    Padayachee, A.L.; Irlich, U.M.; Faulkner, K.T.; Gaertner, M.; Proches, S.; Wilson, J.R.U.; Rouget, M. (Springer, 2017)
    Globalisation has resulted in the movement of organisms outside their natural range, often with negative ecological and economic consequences. As cities are hubs of anthropogenic activities, with both highly transformed ...
  • 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 ...
  • A vision for global monitoring of biological invasions 

    Latombe, G.; Pyšek, P.; Jeschke, J.M.; Blackburn, T.M.; Bacher, W.; Capinha, C.; Costello, C.; Fernández, M.; Gregory, R.D.; Hobern, D.; Hui, C.; Jetz, W.; Kumschick, S.; McGrannachan, C.; Pergl, J.; Roy, H.E.; Scalera, R.; Squires, Z.E.; Wilson, J.R.U.; Winter, M.; Genovesi, P.; McGeoch, M.A. (Elsevier Ltd., 2017)
    Managing biological invasions relies on good global coverage of species distributions. Accurate information on alien species distributions, obtained from international policy and cross-border co-operation, is required to ...
  • Level of environmental threat posed by horticultural trade in Cactaceae 

    Novoa, A.; Le Roux, J.J.; Richardson, D.M.; Wilson, J.R.U. (Society of Conservation Biology, 2017)

  • Assessing and managing the threat posed by Epipremnum aureum in South Africa 

    Moodley, D.; Proches, S.; Wilson, J.R.U. (Elsevier B.V., 2017)
    The predictive success of risk assessments is still largely a function of invasiveness elsewhere. Therefore, species that are invasive elsewhere should be prioritised for management, and where possible eradicated. We set ...
