• Aliens in Antarctica: Accessing transfer of plant propagules by human visitors to reduce invasion risk 

      Huiskes, H.L.(Ad); Gremmen, N.J.M.; Bergstrom, D.M.; Frenot, Y.; Hughes, K.A.; Imura, S.; Kiefer, K.; Lebouvier, M.; Lee, J.E.; Tsujimoto, M.; Ware, C.; Van de Vijver, B.; Chown, S.L. (Elsevier, 2014)
      Despite considerable research on biological invasions, key areas remain poorly explored, especially ways to reduce unintentional propagule transfer. The Antarctic represents a microcosm of the situation, with the numbers ...
    • Continent-wide risk assessment for the establishment of nonindigenous species in Antarctica 

      Chown, S.L.; Huiskes, A.H.L.; Gremmen, N.J.M.; Lee, J.E.; Terauds, A.; Crosbie, K.; Frenot, Y.; Hughes, K.A.; Imura, S.; Kiefer, K.; Lebouvier, M.; Raymond, B.; Tsujimoto, M.; Ware, C.; van de Vijver, B.; Bergstrom, D.M. (2012)
      Invasive alien species are among the primary causes of biodiversity change globally, with the risks thereof broadly understood for most regions of the world. They are similarly thought to be among the most significant ...
    • Impact of anthropogenic transportation to Antarctica on alien seed viability 

      Hughes, K.A.; Lee, J.E.; Ware, C.; Kiefer, K.; Bergstrom, D.M. (Springer-Verlag, 2010-04-27)
      Antarctic ecosystems are at risk from the introduction of invasive species. The first step in the process of invasion is the transportation of alien species to Antarctic in a viable state. However, the effect of longdistance ...
    • Indirect effects of invasive species removal devastate World Heritage Island 

      Bergstrom, D.M.; Lucieer, A.; Kiefer, K.; Wasley, J.; Belbin, L.; Pedersen, T.K.; Chown, S.L. (British Ecological Society, 2009)
      1. Owing to the detrimental impacts of invasive alien species, their control is often a priority for conservation management. Whereas the potential for unforeseen consequences of management is recognized, their associated ...
    • Management implications of the Macquarie Island trophic cascade revisited: a reply to Dowding et al. 

      Bergstrom, D.M.; Lucieer, A.; Kiefer, K.; Wasley, J.; Belbin, L.; Pedersen, T.K.; Chown, S.L. (British Ecological Society, 2009)
      1. The management of non-indigenous species is not without its complications. In Bergstrom et al.'s (2009) study, we demonstrated that feral cats Felis catus on sub-Antarctic Macquarie Island were exerting top-downcontrol ...
