• Competition and feeding ecology in two sympatric Xenopus species (Anura: Pipidae) 

      Vogt, Solveig; De Villiers, F. Andre; Ihlow, Flora; Rodder, Dennis; Measey, John (PeerJ, 2017)
      The widespread African clawed frog (Xenopus laevis) occurs in sympatry with the IUCN Endangered Cape platanna (Xenopus gilli) throughout its entire range in the south-western Cape, South Africa. In order to investigate ...
    • Frog eat frog : exploring variables influencing anurophagy 

      Measey, G. John; Vimercati, Giovanni; De Villiers, F. Andre; Mokhatla, Mohlamatsane M.; Davies, Sarah J.; Edwards, Shelley; Altwegg, Res (PeerJ, 2015)
      Background - Frogs are generalist predators of a wide range of typically small prey items. But descriptions of dietary items regularly include other anurans, such that frogs are considered to be among the most important ...
    • How repeatable is the Environmental Impact Classification of Alien Taxa (EICAT)? Comparing independent global impact assessments of amphibians 

      Kumschick, Sabrina; Measey, G. John; Vimercati, Giovanni; De Villiers, F. Andre; Mokhatla, Mohlamatsane M.; Davies, Sarah J.; Thorp, Corey J.; Rebelo, Alexander D.; Blackburn, Tim M.; Kraus, Fred (Wiley Open Access, 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 ...
    • Impact assessment with different scoring tools : how well do alien amphibian assessments match? 

      Kumschick, Sabrina; Vimercati, Giovanni; De Villiers, F. Andre; Mokhatla, Mohlamatsane M.; Davies, Sarah J.; Thorp, Corey J.; Rebelo, Alexander D.; Measey, G. John (Pensoft Publishers, 2017-01-27)
      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 ...
    • Impacts of climate change on the global invasion potential of the African clawed frog xenopus laevis 

      Ihlow, Flora; Courant, Julien; Secondi, Jean; Herrel, Anthony; Rebelo, Rui; Measey, G. John; Lillo, Francesco; De Villiers, F. Andre; Vogt, Solveig; De Busschere, Charlotte; Backeljau, Thierry; Rodder, Dennis (Public Library of Science, 2016-06-01)
      By altering or eliminating delicate ecological relationships, non-indigenous species are considered a major threat to biodiversity, as well as a driver of environmental change. Global climate change affects ecosystems and ...
