(2020)
      Sustainably managed non-native trees deliver economic and societal benefits with limited risk of spread to adjoining areas. However, some plantations have launched invasions that cause substantial damage to biodiversity ...
    • Introduced and invasive cactus species: a global review 

      Novoa, A.; Le Roux, J.J.; Robertson, M.P.; Wilson, J.R.U.; Richardson, D.M. (Oxford University Press, 2015)
      Understanding which species are introduced and become invasive, and why, are central questions in invasion science. Comparative studies on model taxa have provided important insights, but much more needs to be done to ...
    • Invasion syndromes: a systematic approach for predicting biological invasions and facilitating effective management 

      Novoa, A.; Richardson, D.M.; Pyšek, P.; Meyerson, L.A.; Bacher, S.; Canavan, S.; Catford, J.A.; Čuda, J.; Essl, F.; Foxcroft, L.C.; Genovesi, P.; Hirsch, H.; Hui, C.; Jackson, M.C.; Kueffer, C.; Le Roux, J.J.; Measey, J.; Mohanty, N.P.; Moodley, D.; Müller-Schärer, H.; Packer, J.G.; Pergl, J.; Robinson, T.B.; Saul, W.C.; Shackleton, R.T.; Visser, V.; Weyl, O.L.F.; Yannelli, F.A.; Wilson, J.R.U. (2020)
      Our ability to predict invasions has been hindered by the seemingly idiosyncratic context-dependency of individual invasions. However, we argue that robust and useful generalisations in invasion science can be made by ...
    • 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)
      Ornamental horticulture has been identified as an important threat to plant biodiversity and is a major pathway for plant invasions worldwide. In this context, the family Cactaceae is particularly challenging because it ...
    • MAcroecological Framework for Invasive Aliens (MAFIA): disentangling large-scale context dependence in biological invasions 

      Pyšek, P.; Bacher, S.; Kühn, I.; Novoa, A.; Catford, J.A.; Hulme, P.E.; Pergl, J.; Richardson, D.M.; Wilson, J.R.U.; Blackburn, T.M. (2020)
      Macroecology is the study of patterns, and the processes that determine those patterns, in the distribution and abundance of organisms at large scales, whether they be spatial (from hundreds of kilometres to global), ...
    • Native range size and growth form in Cactaceae predict invasiveness and impact 

      Novoa, A.; Kumschick, S.; Richardson, D.M.; Rouget, M.; Wilson, J.R.U. (Pensoft, 2016)
      Many recent studies in invasion science have identified species traits that determine either invasiveness or impact. Such analyses underpin risk assessments and attempts to prioritise management actions. However, the ...
