      • The effects of past management practices for invasive alien plant control on subsequent recovery of fynbos on the Cape Peninsula, South Africa 

        Parker-Allie, F; Richardson, DM; Holmes, PM (2004)
        Integrated control aimed at reducing impacts of alien woody plant invasions on biodiversity is underway in many parts of the Cape Floristic Region. However, the kinds of control measures applied may themselves affect the ...
      • A reference framework for the restoration of riparian vegetation in the Western Cape, South Africa, degraded by invasive Australian Acacias 

        Prins, N; Holmes, PM; Richardson, DM (2004)
        Riparian vegetation, which normally differs structurally and compositionally from surrounding vegetation, has been degraded in many parts of the fynbos biome by several species of invasive Australian Acacia. Systematic ...
      • Effects of alien plant management and fire on soil seed banks and regeneration in the Cape Peninsula National Park, South Africa 

        Cilliers, C.D.; Esler, K.J.; Boucher, C. (2004)
        The regeneration of alien and indigenous vegetation in various post-fire environments, following the extensive January 2000 wildfires on the Cape Peninsula, South Africa, is described. The effects of dry season wildfire burning ...
      • Hemispheric asymmetries in biodiversity - A serious matter for ecology 

        Chown, SL; Sinclair, BJ; Leinaas, HP; Gaston, KJ (PUBLIC LIBRARY SCIENCE, 2004-11)
      • Plant invasion ecology - dispatches from the front line 

        Richardson, DM (BLACKWELL PUBLISHING LTD, 2004-11-01)
        This issue of Diversity and Distributions carries papers on a wide range of topics dealing with invasions of introduced plant species. The collection of articles did not arise from a conference or workshop, but grew from ...
      • Breeding systems of invasive alien plants 

        Rambuda, T; Johnson, SD (2004-11-01)
        According to Baker’s Rule, plant species capable of uniparental reproduction are more likely to be successful colonists than are self-incompatible or dioecious species. Controlled pollination experiments carried out on 17 ...
      • Reconstructing 50 years of Opuntia stricta invasion in the Kruger National Park, South Africa: environmental determinants and propagule pressure 

        Foxcroft, L.C.; Rouget, M.; Richardson, D.M.; Fadyen, S.M. (2004-11-01)
        Many factors influence the spread dynamics and distribution of invasive alien organisms. Despite progress in unravelling the determinants of invasiveness and invasibility, robust, spatially-explicit predictive models for ...
      • Mapping the potential ranges of major plant invaders in South Africa, Lesotho and Swaziland using climatic suitability 

        Rouget, M.; Richardson, D.M.; Nel, J.L.; Le Maitre, D.C.; Egoh, B.; Mgidi, T. (Blackwell Publishing Ltd, 2004-11-01)
        Most national or regional initiatives aimed at managing biological invasions lack objective protocols for prioritizing invasive species and areas based on likely future dimensions of spread. South Africa has one of the ...
      • Conifers as invasive aliens: a global survey and predictive framework 

        Richardson, DM; Rejmánek, M (2004-11-01)
        We summarize information on naturalized and invasive conifers (class Pinopsida) worldwide (data from 40 countries, some with remote states/territories), and contrast these findings with patterns for other ymnosperms (classes ...
      • Testing for ecological and genetic allee effect in the invasive shrub Senna Diymobotrya (Fabaceae) 

        van Kleunen, M.; Johnson, S.D. (2005)
        For an introduced plant species to become invasive, it must be able to reproduce even in initially small populations. We tested for Allee effects (reduced reproductive performance of individuals in small populations) in ...
      • An exploratory analysis of geographic genetic variation in southern African nyala (Tragelaphus angasii) 

        Grobler, JP; Pretorius, DM; Botha, K; Kotze, A; Hallerman, EM; Jansen van Vuuren, B (URBAN & FISCHER VERLAG, 2005)
        We report patterns of genetic variation based on microsatellite, allozyme and mitochondrial control region markers in nyala from geographic locations sampled in South Africa, Mozambique, Malawi and Zimbabwe. Highly significant ...
      • Potential impacts of future land use and climate change on the Red List status of the Proteaceae in the Cape Floristic Region, South Africa 

        Bomhard, B; Richardson, DM; Donaldson, JS; Hughes, GO; Midgley, GF; Raimondo, T; Rebelo, AG; Rouget, M; Thuiller, W (BLACKWELL PUBLISHING, 2005)
        Using spatial predictions of future threats to biodiversity, we assessed for the first time the relative potential impacts of future land use and climate change on the threat status of plant species. We thus estimated how ...
      • Temperature-dependence of metabolic rate in Glossina morsitans morsitans (Diptera, Glossinidae) does not vary with gender, age, feeding, pregnancy or acclimation 

        Terblanche, JS; Klok, CJ; Chown, SL (PERGAMON-ELSEVIER SCIENCE LTD, 2005)
        While variation in metabolic rate at a single temperature can occur for a variety of reasons and the effect of temperature is well established in insects, within-generation variation of metabolic rate-temperature relationships ...
      • Insect gas exchange patterns: a phylogenetic perspective 

        Marais, E.; Klok, C.J.; Terblanche, J.S.; Chown, S.L. (The Company of Biologists, 2005)
        Most investigations of insect gas exchange patterns and the hypotheses proposed to account for their evolution have been based either on small-scale, manipulative experiments, or comparisons of a few closely related species. ...
      • Inertia in physiological traits: Embryonopsis halticella caterpillars (Yponomeutidae) across the Antarctic Polar Frontal Zone 

        Klok, C.J.; Chown, S.L. (Elsevier Ltd., 2005)
        Geographic variation is characteristic of many physiological traits at the population and species levels. However, several recent studies have suggested that population-level variation is either limited or that it is ...
      • Diversity, distributions and conservation biogeography 

        Richardson, D.M. (Blackwell Publishing Ltd, 2005)
        none
      • The effects of acclimation on thermal tolerance, desiccation resistance and metabolic rate in Chirodica chalcoptera (Coleoptera: Chrysomelidae) 

        Terblanche, J.S.; Sinclair, B.J.; Klok, C.J.; McFarlane, M.L.; Chown, S.L. (Elsevier Ltd, 2005)
        Despite much focus on species responses to environmental variation through space and time, many higher taxa and geographic areas remain poorly studied. We report the effects of temperature acclimation on thermal tolerance, ...
      • The acute hypoxic ventilatory response: Testing the adaptive significance in human populations 

        Terblanche, J.S.; Tolley, K.A.; Fahlman, A.; Myburgh, K.H.; Jackson, S. (Elsevier Inc, 2005)
        The acute Hypoxic Ventilatory Response (HVR) is an important component of human hypoxia tolerance, hence presumably physiological adaptation to high altitude. We measured the isocapnic HVR (L min¯¹ %¯¹) in two genetically ...
      • The world’s biogeographical regions: cluster analyses based on bat distributions 

        Proches, S. (Blackwell Publishing Ltd, 2005)
        Aim: Both floral kingdoms and faunal regions have so far been intuitively defined. This study was conducted to compare these with an analytical regionalization based on cluster analyses in a fairly homogeneous, globally ...
