    • Adaptive diversification in coevolutionary systems 

      Hui, C.; Minoarivelo, H.O.; Nuwagaba, S.; Ramanantoanina, A. (Springer International Publishing Switzerland, 2015)
      Coevolution can trigger frequency-dependent selection by reciprocal effects on the fitness of involved species. Through directional and disruptive selection, coevolution can lead to rich evolutionary possibilities. It can ...

    • Analysing the Risks Posed by Biological Invasions to South Africa 

      Kumschick, S.; Foxcroft, L.C.; Wilson, J.R. (2020)
      Studies of the impact of alien species on the environment are increasingly being carried out, and there has been ongoing debate about how to standardise the description of these impacts. This chapter evaluates the state ...

      Holmes, P.M.; Esler, K.J.; Gaertner, M.; Geerts, S.; Hall, S.A.; Nsikani, M.M.; Richardson, D.M.; Ruwanza, S. (2020)
      This chapter provides an overview of the researchers and research initiatives relevant to invasion science in South Africa over the past 130 years, profiling some of the more recent personalities, particularly those who ...

    • Biological Invasions in South Africa's Urban Ecosystems: Patterns, Processes, Impacts and Management 

      Potgieter, L.J.; Douwes, E.; Gaertner, M.; Measey, J.; Paap, T.; Richardson, D.M. (2020)
      This chapter provides an overview of the researchers and research initiatives relevant to invasion science in South Africa over the past 130 years, profiling some of the more recent personalities, particularly those who ...

    • Biological Invasions in South Africa: an overview 

      van Wilgen, B.W.; Measey, J.; Richardson, D.M.; Wilson, J.R.; Zengeya, T.A. (2020 2020)
      South Africa has much to offer as a location for the study of biological invasions. It is an ecologically diverse country comprised of nine distinct terrestrial biomes, four recognised marine ecoregions, and two sub-Antarctic ...

    • Biological invasions in the Cape Floristic Region: history, current patterns, impacts, and management challenges 

      Wilson, J.R.; Gaertner, M.; Griffiths, C.L.; Kotze, I.; Le Maitre, D.C.; Marr, S.M.; Picker, M.D.; Spear, D.; Stafford, L.; Richardson, D.M.; van Wilgen, B.W.; Wannenburg, A. (Oxford University Press, 2015)
      The Cape Floristic Region (CFR) is the most invaded terrestrial area in South Africa in terms of: the conspicuous prominence of (mainly woody) invasive plants (Fig 12.1, Plate 12) (Henderson 2007); the area invaded as ...

    • Biotic Interactions as Mediators of Biological Invasions: Insights from South Africa 

      Le Roux, J.J.; Clusella-Trullas, S.; Mokotjomela, T.M.; Mairal, M.; Richardson, D.M.; Skein, L.; Wilson, J.R.; Weyl, O.L.F.; Geerts, S. (2020)
      This chapter provides an overview of the researchers and research initiatives relevant to invasion science in South Africa over the past 130 years, profiling some of the more recent personalities, particularly those who ...

    • The bottom line: impacts of alien plant invasions in protected areas 

      Foxcroft, L.C.; Pyšek, P.; Richardson, D.M.; Pergl, J.; Hulme, P.E. (Springer, Dordrecht, 2013)
      Phrases like “invasive species pose significant threats to biodiversity. . .” are often used to justify studying and managing biological invasions. Most biologists agree that this is true and quantitative studies support ...

    • 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 ...

    • A cross-scale approach for abundance estimation of invasive alien plants in a large protected area 

      Hui, C.; Foxcroft, L.C.; Richardson, D.M.; MacFayden, S. (2013)
      Efficient management of invasive alien plants requires robust and cost-efficient methods for measuring the abundance and spatial structure of inva- sive alien plants with sufficient accuracy. Here, we present such a ...

    • Drivers, ecology and management of fire in fynbos 

      Kraaij, T.; van Wilgen, B.W. (Oxford University Press, 2015)
      Fire is a fundamental driving force in fynbos dynamics, being both inevitable and necessary in fynbos ecosystems (Kruger and Bigalke 1984). Fire has also played a key role in stimulating the evolutionary diversification ...

    • Invasive alien plants in protected areas: threats, opportunities, and the way forward. 

      Foxcroft, L.C.; Richardson, D.M.; Pyšek, P.; Genovesi, P. (Springer, Dortrecht, 2013)
      The potential threats posed by biological invasions are widely appreciated, but the state of knowledge and level of management of invasive alien plants in protected areas differs considerably across the world. Research ...

    • Non-native species and the aesthetics of nature 

      Kueffer, C.; Kull, C.A. (Springer International Publishing Switzerland 2017, 2017)
      How humans perceive and judge nature and relate it to their life is shaped by emotional, cognitive, cultural, and social factors. Whether a species is considered native, non-native, or invasive can affect such aesthetics ...
