    Novoa, A.; Shackleton, R.; Canavan, S.; Cybele, C.; Davies, S.J.; Dehnen-Schmutz, K.; Fried, J.; Gaertner, M.; Geerts, S.; Griffiths, C.L.; Kaplan, H.; Kumschick, S.; Le Maitre, D.C.; Measey, G.J.; Nunes, A.L.; Richardson, D.M.; Robinson, T.B.; Touza, J.; Wilson, J.R.U. (Elsevier Ltd., 2018)
    Alien species can have major ecological and socioeconomic impacts in their novel ranges and so effective management actions are needed. However, management can be contentious and create conflicts, especially when stakeholders ...
  • Does restricted access limit management of invasive urban frogs? 

    Vimercati, G.; Davies, S.J.; Hui, C.; Measey, J. (Springer, 2017)
    Management recommendations that target urban invaders should consider environmental and socio-economic aspects peculiar to the urban landscape. Urbanization often leads to the fragmentation of the invaded landscape into ...
  • Integrating age structured and landscape resistance models to disentangle invasion dynamics of a pond-breeding anuran 

    Vimercati, G.; Hui, C.; Davies, S.J.; Measey, G.J. (Elsevier B.V., 2017)
    Modelling population dynamics of invasive species may help to propose effective management countermeasures. Invasion dynamics generally show recursive patterns across species and regions, where initial lag is followed by ...
  • How repeatable is the Environmental Impact Classification of Alien Taxa (EICAT)? Comparing independent global impact assessments of amphibians 

    Kumschick, S.; Measey, G.J.; Vimercati, G.; de Villiers, F.A.; Mokhatla, M.M.; Davies, S.J.; Thorp, C.J.; Rebelo, A.D.; Blackburn, T.M.; Kraus, F. (John Wiley & Sons Ltd., 2017)
    The magnitude of impacts some alien species cause to native environments makes them targets for regulation and management. However, which species to target is not always clear, and comparisons of a wide variety of impacts ...
  • Invasive amphibians in southern Africa: A review of invasion pathways 

    Measey, J.; Davies, S.J.; Vimercati, G.; Rebelo, A.; Schmidt, W.; Turner, A. (AOSIS, 2017)
    Background: Globally, invasive amphibians are known for their environmental and social impacts that range from poisoning of local fauna and human populations to direct predation on other amphibians. Although several ...
  • Impact assessment with different scoring tools; How well do alien amphibian assessments match? 

    Kumschick, S.; Vimercati, G.; de Villiers, F.A.; Mokhatla, M.M.; Davies, S.J.; Thorp, C.J.; Rebelo, A.D.; Measey, G.J. (Pensoft Publishers, 2017)
    Classification of alien species’ impacts can aid policy making through evidence based listing and management recommendations. We highlight differences and a number of potential difficulties with two scoring tools, the ...
  • A global assessment of alien amphibian impacts in a formal framework 

    Measey, G.J.; Vimercati, G.; de Villiers, F.A.; Mokhatla, M.; Davies, S.J.; Thorp, C.J.; Rebelo, A.D.; Kumschick, S. (John Wiley & Sons Ltd, 2016)
    Aims The environmental and socio-economic impacts of alien species need to be quantified in a way that makes impacts comparable. This allows managers to prioritize their control or removal based on impact scores that can ...
  • Science and education at the Centre for Invasion Biology 

    Davies, S.J.; Measey, G.J.; du Plessis, D.; Richardson, D.M. (Springer International Publishing, 2016)
    South Africa has severe problems caused by biological invasions in terrestrial, freshwater and marine ecosystems, and a long history of managing biological invasions. However, appreciation and systematic study of the ...
  • Soil biota in a megadiverse country: Current knowledge and future research directions in South Africa 

    Janion-Scheepers, C.; Measey, J.; Braschler, B.; Chown, S.L.; Coetzee, L.; Colville, J.F.; Dames, J.; Davies, A.B.; Davies, S.J.; Davis, A.L.V.; Dippenaar-Schoeman, A.S.; Duffy, G.A.; Fourie, D.; Griffiths, C.; Haddad, C.R.; Hamer, M.; Herbert, D.G.; Hugo-Coetzee, E.A.; Jacobs, A.; Jacobs, K.; Jansen van Rensburg, C.; Lamani, S.; Lotz, L.N.; vdM.

(Elsevier GmbH, 2016)
    Soils are integral to agricultural productivity, biodiversity, and the maintenance of ecosystem services. However, soil ecosystem research depends on foundational biological knowledge that is often missing. In this review, ...
  • Plasticity of thermal tolerance and metabolism but not water loss in an invasive reed frog 

    Davies, S.J.; McGeoch, M.A.; Clusella-Trullas, S. (Elsevier Inc., 2015)
    Phenotypic plasticity may buffer the selection pressures on organisms that inhabit novel or rapidly-changing environments. We investigated plasticity of thermal tolerance, energetic and water loss traits and their interaction ...
  • Climate change and alien species in South Africa 

    Irlich, U.M.; Richardson, D.M.; Davies, S.J.; Chown, S.L. (CAB International, 2015)
    South Africa has a long history of human-mediated introductions of species from all major taxonomic groups. Close to 9000 alien terrestrial plant species have been introduced, and all of the country’s biomes have already ...
