      This paper explores how a lack of taxonomic expertise, and by implication a dearth of taxonomic products such as identification tools, has hindered progress in understanding and managing biological invasions. It also ...

    • 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 ...

    • How much evolutionary history in a 10x10m plot? 

      Proches, S.; Wilson, J.R.U.; Cowling, R.M. (2006)
      We use a fully dated phylogenetic tree of the angiospermfamilies to calculate phylogenetic diversity (PD) in four South African vegetation types with distinct evolutionary histories. Since the branch length values are in ...

      Aim Australian acacias (1012 recognized species native to Australia, which were previously grouped in Acacia subgenus Phyllodineae) have been moved extensively around the world by humans over the past 250 years. This has ...

    • Identifying safe cultivars of invasive plants: six questions for risk assessment, management, and communication 

      Datta, A.; Kumschick, S.; Geerts, S.; Wilson, J.R.U. (2020)
      The regulation of biological invasions is often focussed at the species level. However, the risks posed by infra- and inter-specific entities can be significantly different from the risks posed by the corresponding species, ...

    • The importance of pollinators and autonomous self-fertilisation in the early stages of plant invasions: Banksia and Hakea (Proteaceae) as case studies 

      Moodley, D.; Geerts, S.; Richardson, D.M.; Wilson, J.R.U. (German Botanical Society and the Royal Botanical Society of the Netherlands, 2016)
      Reproduction is a crucial stage in the naturalisation of introduced plant species. Here, using breeding system experiments and observations of floral visitors, we investigate whether a lack of pollinators or an inability ...

    • Improving Darwin Core for research and management of alien species 

      Groom, Q.; Desmet, P.; Reyserhove, L.; Adriaens, T.; Oldoni, D.; Vanderhoeven, S.; Baskauf, S.J.; Chapman, A.; McGeoch, M.; Walls, R.; Wieczorek, J.; Wilson, J.R.U.; Zermoglio, P.F.F.; Simpson, A. (2019)
      To improve the suitability of the Darwin Core standard for the research and management of alien species, the standard needs to express the native status of organisms, how well established they are and how they came to ...

    • Incorporating risk mapping at multiple spatial scales into eradication management plans 

      Kaplan, H.; van Niekerk, A.; le Roux, J.J.; Richardson, D.M.; Wilson, J.R.U. (Springer, 2014)
      The success of pro-active management of invasive plants depends on the ability to rapidly detect invasive populations and individuals. However, the factors important for detection depend on the spatial scale examined. We ...

    • Indicators for monitoring biological invasions at a national level 

      Wilson, J.R.U.; Faulkner, K.T.; Rahlao, S.J.; Richardson, D.M.; Zengeya, T.A.; van Wilgen, B.W. (British Ecological Society, 2018)
      1. A major challenge for the management of biological invasions is to ensure that data and information from basic inventories and ecological research are used alongside data from the monitoring and evaluation of interventions ...

    • Initiating dialogue between scientists and managers of biological invasions 

      Shaw, J.D.; Wilson, J.R.U.; Richardson, D.M. (Springer, 2010)
      We describe an initiative to improve the flow of information between researchers and managers as part of two international scientific symposia on biological invasions held in South Africa in 2008 and 2009. Formal ...

      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 ...

      Donaldson, J.E.; Hui, C.; Richardson, D.M.; Robertson, M.P.; Webber, B.L.; Wilson, J.R.U. (John Wiley & Sons Ltd., 2014)
      Global change is driving a massive rearrangement of the world’s biota. Trajectories of distributional shifts are shaped by species traits, the recipient environment and driving forces with many of the driving forces directly ...
