• Alien species and propagules in the Antarctic: movements though space and time 

      Lee, Jennifer (2009-02-19)
      Although the impacts of biological invasions are widely appreciated, a bias exists in research effort to post-dispersal processes because of the difficulties of measuring propagule pressure and the detecting of newly ...
    • Invasive potential of the Peruvian pepper tree (Schinus molle) in South Africa 

      Midoko Iponga, Donald; Richardson, David M.; Milton, Suzanne J. (2009-05-21)
      We investigated the potential of an invasive alien tree to transform vegetation by quantifying the relative abilities of the alien tree Schinus molle and dominant native trees Acacia tortilis and Rhus lancea to compete for ...
    • Megastigmus wasp damage to seeds of Schinus molle 

      Midoko Iponga, Donald; Richardson, David M.; Milton, Suzanne J. (2009-05-29)
      Understanding the reasons why some alien species become invasive may help to identify appropriate management strategies. One hypothesis often cited to explain invasion success is the enemy release hypothesis (Williams 1954; ...
    • Soil type, microsite, and herbivory influence S.molle growth 

      Midoko Iponga, Donald; Richardson, David M.; Milton, Suzanne J. (2009-05-29)
      The study involved a field manipulation experiment over 14 months using a factorial block design to examine transplanted seedlings in different savanna environments. The experiments examine the effects of soil type (sandy ...
