An assessment of the information content of South African alien species databases
National alien species databases indicate the state of a country’s biodiversity and provide useful data for research on invasion biology and the management of invasions. In South Africa there are several different published ...
Unequal contribution of native South African phylogeographic lineages to the invasion of the African clawed frog, Xenopus laevis, in Europe
Due to both deliberate and accidental introductions, invasive African Clawed Frog (Xenopus laevis) populations have become established worldwide. In this study, we investigate the geographic origins of invasive X. laevis ...
Troubling travellers : are ecologically harmful alien species associated with particular introduction pathways?
(Pensoft Publishers, 2017)
Prioritization of introduction pathways is seen as an important component of the management of biological invasions. We address whether established alien plants, mammals, freshwater fish and terrestrial invertebrates ...
Global realized niche divergence in the African clawed frog Xenopus laevis
(John Wiley & Sons Ltd, 2017)
Although of crucial importance for invasion biology and impact assessments of climate change, it remains widely unknown how species cope with and adapt to environmental conditions beyond their currently realized climatic ...
Spatial sorting drives morphological variation in the invasive bird, Acridotheris tristis
(PLoS One, 2012-05)
The speed of range expansion in many invasive species is often accelerating because individuals with stronger dispersal abilities are more likely to be found at the range front. This ‘spatial sorting’ of strong dispersers ...
Species-energy relationships of indigenous and invasive species may arise in different ways – a demonstration using springtails
(Nature Publishing Group, 2019-09-24)
ENGLISH ABSTRACT: Although the relationship between species richness and available energy is well established for a range of spatial scales, exploration of the plausible underlying explanations for this relationship is ...
