      • Distribution and impact of the Argentine ant, Linepithema humile (Mayr), in South Africa 

        Luruli, NM (2007-08-14)
        Invasion by the notorious tramp species, the Argentine ant (Linepithema humile Mayr) (Hymenoptera: Formicidae) has caused major concern around the globe, owing to its displacement of native ant species and other invertebrates ...
      • An assessment of anthropogenic threats to areas important for frog conservation in South Africa 

        Mokhatla, McDonald (2008-05-09)
        Recent studies on conservation and species threat level assessments have advocated the importance of human demographic variables and other associated variables in determining threats to biodiversity. In addition to this, ...
      • Implications of global change for Important Bird Areas in South Africa 

        Coetzee, B.W.T. (2008-06-11)
        The Important Bird Areas (IBAs) network of BirdLife International aims to identify sites that are essential for the long-term conservation of the world’s avifauna. A number of global change events have the potential to ...
      • The relative importance of natural and human-induced environmental conditions for species richness distribution patterns in South Africa 

        Hugo, Sanet (2008-06-20)
        I studied the spatial distribution of South African avian species richness from the viewpoint that humans are a substantial modifying force on earth, and have also modified the historical spatial distribution of species ...
      • Distribution of the invasive alien tree Schinus molle in western South Africa 

        Midoko Iponga, Donald; Richardson, David M.; Milton, Suzanne J. (2009-05-20)
        We examined the distribution of the invasive alien tree Schinus molle (Peruvian pepper tree; Anacardiaceae) in South Africa, where it was planted over large areas. Localities of planted and naturalized trees were mapped ...
      • Current and future vulnerability of South African ecosystems to perennial grass invasion under global change scenarios 

        Rahlao, Sebataolo (2010-01-18)
        Invasive alien grasses are a group of increasing importance which respond to global changes and alter native plant community structure and ecosystem processes. To date there have been few studies that assess the ecological ...
      • Vulnerability of Selected Native and Invasive Woody Riparian Species to Streamflow Variability in the Western Cape Fynbos Ecosystem 

        Crous, Casparus Johannes (2010-08-11)
        Riparian ecosystems of the Mediterranean south-western Cape region are projected to experience significant decreases in streamflow due to climate change and increased demands for water associated with human demographic ...
      • Investigating the influence of data quality on ecological niche models for alien plant invaders 

        Wolmarans, René (2010-10-04)
        Ecological niche modeling is a method designed to describe and predict the geographic distribution of an organism. This procedure aims to quantify the species-environment relationship by describing the association between ...
      • White rhino populations in the Eastern Cape: distribution, perfomance and diet 

        Kraai, Manqhai; Kerley, Graham (2010-11-11)
        White rhinoceros did not occur historically in the Eastern Cape (Skead 2007). However, they were introduced in the Eastern Cape in state-run reserves and private land (Shrader 2006). White rhino have been introduced for ...
      • Integrating ecosystem services into conservation planning in South Africa 

        Egoh, Benis Nchine (2010-11-25)
        This thesis contains seven chapters that deals with the intergration of ecosystem services into conservation planning in South Africa. It starts with a review on the inclusion of ecosystem services in conservation plans, ...
      • Species assembly patterns and protected area effectiveness in times of change: a focus on African avifauna 

        Coetzee, Bernard (2013-08-15)
        The challenge of conserving biodiversity is daunting. Despite some local conservation gains, most indicators of the condition of global biodiversity show declines since the 1970’s, while indicators of the threats to ...
      • Casuarina invasions: a multi-scale assessment of an important tree genus 

        Potgieter, Luke John (2013-11-20)
        Understanding the processes that drive the invasion of non-native species is often essential for effective management. This thesis focuses on Casuarina spp. – an economically and ecologically important tree genus with taxa ...
      • Identifying high risk pathways and species to prevent biological invasions in South Africa 

        Faulkner, Katelyn Terri (2015-10-26)
        Data were extracted from alien species databases on alien species in South Africa, on their pathways and dates of introduction, their regions of origin, South African distribution and invasion status. These data were used ...
