  • The importance of assessing positive and beneficial impacts of alien species 

    Vimercati, G.; Kumschick, S.; Probert, A.F.; Volery, L.; Bacher, S. (2020)
    Extensive literature is available on the diversity and magnitude of impacts that alien species cause on recipient systems. Alien species may decrease or increase attributes of ecosystems (e.g. total biomass or species ...
  • 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, ...
  • Frameworks used in invasion science: progress and prospects 

    Wilson, J.R.U.; Bacher, S.; Daehler, C.C.; Groom, Q.J.; Kumschick, S.; Lockwood, J.L.; Robinson, T.B.; Zengeya, T.A.; Richardson, D.M. (2020)
    Our understanding and management of biological invasions relies on our ability to classify and conceptualise the phenomenon. This need has stimulated the development of a plethora of frameworks, ranging in nature from ...
