Are road verges corridors for weed invasion? Insights from the fine-scale spatial genetic structure of Raphanus raphanistrum
(European Weed Research Society, 2013)
Raphanus raphanistrum (Brassicaceae) is considered amongst the world’s worst agricultural weeds. We address critical issues in its management by studying the pathway of colonisation at local scales. For this, we assessed ...
Long-distance dispersal maximizes evolutionary potential during rapid geographic range expansion
Conventional wisdom predicts that sequential founder events will cause genetic diver- sity to erode in species with expanding geographic ranges, limiting evolutionary potential at the range margin. Here, we show that ...
Patterns of weed invasion: evidence from the spatial genetic structure of Raphanus raphanistrum
(Springer Science+Business Media Dordrecht, 2013)
Knowledge of the pathways of colonization is critical for risk assessment and management of weeds. In this study we adopted a landscape genetics approach to assess the impact of human disturbances and large-scale ...
Population genetics of Ceratitis capitata in South Africa: Implications for dispersal and pest management
(Public Library of Science, 2013)
The invasive Mediterranean fruit fly (medfly), Ceratitis capitata, is one of the major agricultural and economical pests globally. Understanding invasion risk and mitigation of medfly in agricultural landscapes requires ...
Biogeography and host-related factors trump parasite life history: limited congruence among the genetic structures of specific ectoparasitic lice and their rodent hosts
(John Wiley & Sons Ltd, 2013)
Parasites and hosts interact across both micro- and macroevolutionary scales where congruence among their phylogeographic and phylogenetic structures may be observed. Within southern Africa, the four-striped mouse genus, ...
Pan-African genetic structure in the African buffalo (Syncerus caffer): investigating intraspecific divergence
The African buffalo (Syncerus caffer) exhibits extreme morphological variability, which has led to controversies about the validity and taxonomic status of the various recognized subspecies. The present study aims to ...
