  • Adaptive evolution in invasive species 
    Prentis, P.J.   Wilson, J.R.U.   Dormontt, E.E.   Richardson, D.M.   Lowe, A.J. (Elsevier Ltd., 2008)
    Many emerging invasive species display evidence of rapid adaptation. Contemporary genetic studies demonstrate that adaptation to novel environments can occur within 20 generations or less, indicating that evolutionary ...
  • Alien invaders and reptile traders: what drives the live animal trade in South Africa? 
    van Wilgen, N.J.   Wilson, J.R.U.   Elith, J.   Wintle, B.A.   Richardson, D.M. (The Zoological Society of London, 2010)
    The global trade in reptiles for pets has grown rapidly in recent decades. Some species introduced by the pet trade have established and become invasive, for example the Burmese python in Florida. Although there are currently ...
  • The (bio)diversity of science reflects the interests of society 
    Wilson, J.R.U.   Procheş, Ş.   Braschler, B.   Dixon, E.S.   Richardson, D.M. (2007)
    For ecologists to develop robust generalizations and principles, a broad taxonomic and geographic spread of research is required, but, in practice, most generalizations are based on the research of individual scientists ...
  • Biogeographic concepts define invasion biology 
    Wilson, J.R.U.   Dormontt, E.E.   Prentis, P.J.   Lowe, A.J.   Richardson, D.M. (Elsevier, 2009-11)
  • Herbivores, but not other insects, are scarce on alien plants 
    Proches, S.   Wilson, J.R.U.   Richardson, D.M.   Chown, S.L. (Ecological Society of Australia, 2008)
    Understanding how the landscape-scale replacement of indigenous plants with alien plants influences ecosystem structure and functioning is critical in a world characterized by increasing biotic homogenization. An important ...
  • 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 workshops ...
  • Interactions between environment, species traits, and human uses describe patterns of plant invasions 
    Thuiller, W.   Richardson, D.M.   Rouget, M.   Procheş, Ş.   Wilson, J.R.U. (ECOLOGICAL SOC AMER, 2006-07)
    Although invasive alien species (IAS) are a major threat to biodiversity, human health, and economy, our understanding of the factors controlling their distribution and abundance is limited. Here, we determine how environmental ...
  • Invasive alien plants infiltrate bird-mediated shrub nucleation processes in arid savanna 
    Milton, S.J.   Wilson, J.R.U.   Richardson, D.M.   Seymour, C.L.   Dean, W.R.J.   Iponga, D.M.   Procheş, Ş. (Blackwell, 2007)
    1 The cultivation and dissemination of alien ornamental plants increases their potential to invade. More specifically, species with bird-dispersed seeds can potentially infiltrate natural nucleation processes in savannas. 2 To ...
  • Landscape corridors: Possible dangers? 
    Procheş, Ş.   Wilson, J.R.U.   Veldtman, R.   Kalwij, J.M.   Richardson, D.M.   Chown, S.L. (AMER ASSOC ADVANCEMENT SCIENCE, 2005-11-04)
  • Organismal complexity is an indicator of species existence value 
    Wilson, J.R.U.   Proches, S.   Braschler, B.   Dixon, E.S.   Richardson, D.M. (The Ecological Society of America, 2008)
  • Ornamental plants as invasive aliens: problems and solutions in Kruger National Park, South Africa 
    Foxcroft, L.C.   Richardson, D.M.   Wilson, J.R.U. (Springer Science+Business Media, LLC, 2008)
    The most widespread invasive alien plant species in South Africa’s Kruger National Park (KNP) were either introduced unintentionally along rivers and roads, or intentionally for use as ornamentals. We examine the spatial ...
  • Plant diversity in the human diet: weak phylogenetic signal indicates breadth 
    Proches, S.   Wilson, J.R.U.   Vamosi, J.C.   Richardson, D.M. (American Institute of Biological Sciences, 2008-02)
    Worldwide, humans have access to a greater range of food plants than does any other species. Examination of phylogenetic patterns in plants consumed by animals has recently uncovered important ecological processes. The ...
  • Residence time and potential range: crucial considerations in modelling plant invasions 
    Wilson, J.R.U.   Richardson, D.M.   Rouget, M.   Procheş, Ş.   Amis, M.A.   Henderson, L.   Thuiller, W. (2007)
    A prime aim of invasion biology is to predict which species will become invasive, but retrospective analyses have so far failed to develop robust generalizations. This is because many biological, environmental, and ...
  • Searching for phylogenetic pattern in biological invasions 
    Proches, S.   Wilson, J.R.U.   Richardson, D.M.   Rejmánek, M. (Blackwell Publishing Ltd, 2008)
    It has been suggested that alien species with close indigenous relatives in the introduced range may have reduced chances of successful establishment and invasion (Darwin’s naturalization hypothesis). Studies trying to ...
  • Something in the way you move: dispersal pathways affect invasion success 
    Wilson, J.R.U.   Dormontt, E.E.   Prentis, P.J.   Lowe, A.J.   Richardson, D.M. (Elsevier Ltd., 2009)
    Biological invasions are caused by human-mediated extra-range dispersal and, unlike natural extra-range dispersal, are often the result of multiple introductions from multiple sources to multiple locations. The processes ...
