      Background: The influence of introduction history and post-introduction dynamics on genetic diversity and structure has been a major research focus in invasion biology. However, genetic diversity and structure in the ...

      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 ...

    • 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 ...

      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 ...

    • Intentionally introduced terrestrial invertebrates: patterns, risks, and options for management 

      Kumschick, S.; Devenish, A.; Kenis, M.; Rabitsch, W.; Richardson, D.M.; Wilson, J.R.U. (2016-04-21)
