  • Urbanization and Carpobrotus edulis invasion alter the diversity and composition of soil bacterial communities in coastal areas 

    Novoa, A.; Keet, J.H.; Lechuga-Lago, Y.; Pyšek, P.; Le Roux, J.J. (2020)
    Coastal dunes are ecosystems of high conservation value that are strongly impacted by human disturbances and biological invasions in many parts of the world. Here we assessed how urbanization and Carpobrotus edulis invasion ...
  • The potential evolutionary impact of invasive balloon vines on native soapberry bugs in South Africa 

    Foster, J.D.; Ellis, A.G.; Foxcroft, L.C.; Carroll, S.P.; Le Roux, J.J. (2019)
    Following their establishment in new communities, invasive species may cause evolutionary changes in resident native species. This is clearly true for phytophagous insects, which may adapt rapidly when utilising abundant ...
  • Cointroductions of Australian acacias and their rhizobial mutualists in the Southern Hemisphere 

    Warrington, S.; Ellis, A.; Novoa, A.; Wandrag, E.M.; Hulme, P.E.; Duncan, R.P.; Valentine, A.; Le Roux, J.J. (2019)
    Aim Mutualisms are often disrupted for plants introduced to new ranges, yet many of these plants have managed to obtain effective mutualistic associations in their new ranges. There are two potential pathways for non-native ...
  • Characteristics of the soil seed bank of invasive and non-invasive plants in their native and alien distribution range 

    Gioria, M.; Le Roux, J.J.; Hirsch, H.; Moravcova, L.; Pysek, P. (Springer, 2019)
    The ability to form persistent seed banks might contribute substantially to determine the invasion potential of alien plants in their new distribution ranges, given the role of seed banks as sources of propagules, genetic ...
  • Importance of soil legacy effects and successful mutualistic interactions during Australian acacia invasions in nutrient-poor environments 

    Le Roux, J.J.; Ellis, A.G.; van Zyl, L.-M.; Hosking, N.D.; Keet, J.-H.; Yannelli, F.A. (British Ecological Society, 2018)
    1. Non-native plants often alter environments they invade, favouring their own performance through positive feedbacks. Plant–soil interactions represent one such mechanism, but their complexity (e.g. invader-induced changes ...
