  • A taxonomic revision of seed harvester ants of the Tetramorium solidum group (Hymenoptera: Formicidae) in southern Africa 

    Mbanyana, N.; Hita Garcia, F.; Robertson, H.G.; Le Roux, J.J. (Creative Commons Attribution, 2018)
    Ants of the Tetramorium solidum group occur in Africa, with the vast majority of species endemic to the arid regions of southern Africa. The first revision of the genus was published more than 30 years ago and ant surveys ...
  • Even well-studied groups of alien species might be poorly inventoried: Australian Acacia species in South Africa as a case study 

    Magona, N.; Richardson, D.M.; Le Roux, J.J.; Kritzinger-Klopper, S.; Wilson, J.R.U. (Pensoft, 2018)
    Understanding the status and extent of spread of alien plants is crucial for effective management. We explore this issue using Australian Acacia species (wattles) in South Africa (a global hotspot for wattle introductions ...
  • Historical range contraction, and not taxonomy, explains the contemporary genetic structure of the Australian tree, Acacia dealbata Link 

    Hirsch, H.; Richardson, D.M.; Impson, F.A.C.; Kleinjan, C.; Le Roux, J.J. (Springer, 2018)
    Irrespective of its causes, strong population genetic structure indicates a lack of gene flow. Understanding the processes that underlie such structure, and the spatial patterns it causes, is valuable for conservation ...
  • Reassessing the invasion of South African waters by the European shore-crab Carcinus maenas 

    Mabin, C.A.; Wilson, J.R.U.; Le Roux, J.J.; Robinson, T.B. (NISC (Pty) Ltd, 2017)
    The European shore-crab Carcinus maenas has been present in South Africa since 1983. Despite this species’ international reputation as a biological invader, its distribution in this region has only been considered by three ...
  • Understanding the influence of urbanization on invasibility: Carpobrotus edulis as an exemplar 

    Lechuga-Lago, Y.; Novoa, A.; Le Roux, J.J.; Gonzalez, L. (Springer, 2017)
    Coastal dune areas are valuable ecosystems, generally impacted by habitat destruction and invasive alien species. In this study, we assessed how human disturbance and invasion by Carpobrotus edulis impact the soils and ...
  • Introduction to the special issue: Tree invasions: towards a better understanding of their complex evolutionary dynamics 

    Hirsch, H.; Richardson, D.M.; Le Roux, J.J. (Oxford University Press, 2017)
    Many invasive plants show evidence of trait-based evolutionary change, but these remain largely unexplored for invasive trees. The increasing number of invasive trees and their tremendous impacts worldwide, however, illustrates ...
  • Soil nutritional status and biogeography influence rhizosphere microbial communities associated with the invasive tree Acacia dealbata 

    Kamutando, C.N.; Vikram, S.; Kamgan-Nkuekam, G.; Makhalanyane, T.P.; Greve, M.; Le Roux, J.J.; Richardson, D.M.; Cowan, D.; Valverde, A. (Macmillan Publishers Limited, 2017)
    Invasiveness and the impacts of introduced plants are known to be mediated by plant-microbe interactions. Yet, the microbial communities associated with invasive plants are generally poorly understood. Here we report on ...
  • Level of environmental threat posed by horticultural trade in Cactaceae 

    Novoa, A.; Le Roux, J.J.; Richardson, D.M.; Wilson, J.R.U. (Society of Conservation Biology, 2017)
    Ornamental horticulture has been identified as an important threat to plant biodiversity and is a major pathway for plant invasions worldwide. In this context, the family Cactaceae is particularly challenging because it ...
  • Co-introduction vs ecological fitting as pathways to the establishment of effective mutualisms during biological invasions 

    Le Roux, J.J.; Hui, C.; Keet, J.-H.; Ellis, A.G. (New Phytologist Trust, 2017)
    Interactions between non-native plants and their mutualists are often disrupted upon introduction to new environments. Using legume–rhizobium mutualistic interactions as an example, we discuss two pathways that can influence ...
  • Unresolved native range taxonomy complicates inferences in invasion ecology: Acacia dealbata Link as an example 

    Hirsch, H.; Gallien, L.; Impson, F.A.C.; Kleinjan, C.; Richardson, D.M.; Le Roux, J.J. (Springer, 2017)
    Elaborate and expensive endeavours are underway worldwide to understand and manage biological invasions. However, the success of such efforts can be jeopardised due to taxonomic uncertainty. We highlight how unresolved ...
  • ABSTRACT: Legume-rhizobium symbiotic promiscuity and effectiveness do not affect plant invasiveness 

    Keet, J.-H.; Ellis, A.G.; Hui, C.; le Roux, J.J. (Elsevier B.V., 2017)
  • A rapid survey of the invasive plant species in western Angola 

    Rejmanek, M.; Huntley, B.J.; Le Roux, J.J.; Richardson, D.M. (John Wiley & Sons, 2017)
    Angola is one of the most neglected African countries in terms of botanical research, in respect of both native and naturalized species. We conducted a rapid assessment of invasive plant species in western Angola during ...
  • Ecological disequilibrium drives insect pest and pathogen accumulation in non-native trees 

    Crous, C.J.; Burgess, T.I.; Le Roux, J.J.; Richardson, D.M.; Slippers, B.; Wingfield, M.J. (Oxford University Press, 2017)
    Non-native trees have become dominant components of many landscapes, including urban ecosystems, commercial forestry plantations, fruit orchards and as invasives in natural ecosystems. Often, these trees have been separated ...
  • Evolutionary dynamics of tree invasions: complementing the unified framework for biological invasions 

    Zenni, R.D.; Dickie, I.A.; Wingfield, M.J.; Hirsch, H.; Crous, C.J.; Meyerson, L.A.; Burgess, T.I.; Zimmermann, T.G.; Klock, M.M.; Siemann, E.; Erfmeier, A.; Aragon, R.; Montti, L.; Le Roux, J.J. (Oxford University Press, 2017)
    Evolutionary processes greatly impact the outcomes of biological invasions. An extensive body of research suggests that invasive populations often undergo phenotypic and ecological divergence from their native sources. ...
  • Is invasion success of Australian trees mediated by their native biogeography, phylogenetic history, or both? 

    Miller, J.T.; Hui, C.; Thornhill, A.H.; Gallien, L.; Le Roux, J.J.; Richardson, D.M. (Oxford University Press, 2017)
    For a plant species to become invasive it has to progress along the introduction-naturalization-invasion (INI) continuum which reflects the joint direction of niche breadth. Identification of traits that correlate with and ...
  • The global distribution of bamboos: assessing correlates of introduction and invasion 

    Canavan, S.; Richardson, D.M.; Visser, V.; Le Roux, J.J.; Voronstsova, M.S.; Wilson, J.R.U. (Oxford University Press, 2017)
    There is a long history of species being moved around the world by humans. These introduced species can provide substantial benefits, but they can also have undesirable consequences. We explore the importance of human ...
  • The structure of legume – rhizobium interaction networks and their response to tree invasions 

    Le Roux, J.J.; Mavengere, N.R.; Ellis, A.G. (Oxford University Press, 2016)
    Establishing mutualistic interactions in novel environments is important for the successful establishment of some non-native plant species. These associations may, in turn, impact native species interaction networks as ...
