  1. South African ecotoxicology — present status and future prognosis

    South African ecotoxicology — present status and future prognosis

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Toxicology studies the interactions of a chemical substance with individual organisms, whereas ecotoxicology is a multidisciplinary approach incorporating ecology and other disciplines, e.g. chemistry, microbiology, etc., to determine responses of individuals, populations and whole ecosystems to stressors such as chemicals...
  2. Syndromes of dryland degradation in southern Africa

    Syndromes of dryland degradation in southern Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Dryland degradation (in other words, desertification) is defined for the purposes of this paper as a persistent decrease in the capacity of an arid or semiarid ecosystem to supply a range of services, including (but not restricted to) forage, fuel,...
  3. Assessment of the long-term response to rehabilitation of two wetlands in KwaZulu-Natal, South Africa

    Assessment of the long-term response to rehabilitation of two wetlands in KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Assessing the ecological outcomes of wetland rehabilitation activities is an important need recognised by the ‘Working for Wetlands’ programme in South Africa. An assessment of ecological response was conducted in the Killarney and Kruisfontein wetlands, KwaZulu-Natal, in 2005 prior to...
  4. Small mammal diversity and density on the Bokkeveld escarpment, South Africa – implications for conservation and livestock predation

    Small mammal diversity and density on the Bokkeveld escarpment, South Africa – implications for conservation and livestock predation

    Item type: Journal Article • Journal: African Zoology
    A preliminary investigation of the diversity and density of small mammals in four structurally distinct habitat types in an actively-utilized farming landscape was carried out. We sought to understand how diversity and density are influenced by landscape structure, habitat structure...
  5. Studying the Logone floodplain, Cameroon, as a coupled human and natural system<xref ref-type="fn" rid="FN0001"/>

    Studying the Logone floodplain, Cameroon, as a coupled human and natural system<xref ref-type="fn" rid="FN0001"/>

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    African floodplains are an excellent example of coupled human–natural systems because they exhibit strong interactions among multiple social, ecological, and hydrological systems. The intra-annual and interannual variations in seasonal flooding have direct and indirect impacts on ecosystems and human lives...
  6. Mangrove reforestation: greening or grabbing coastal zones and deltas? Case studies in Senegal<xref ref-type="fn" rid="FN0001"/>

    Mangrove reforestation: greening or grabbing coastal zones and deltas? Case studies in Senegal<xref ref-type="fn" rid="FN0001"/>

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Besides their important contribution to global biodiversity, mangroves provide many services. Nevertheless, due to an increase of human activities and to climate change, in less than 20 years these ecosystems have lost one fifth of their global surface area. In...
  7. Land use change and its drivers in Kurt Bahir wetland, north-western Ethiopia

    Land use change and its drivers in Kurt Bahir wetland, north-western Ethiopia

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The effects of land-use change on ecosystem services in Kurt Bahir wetland were investigated during 2013 to 2014 using LANDSAT satellite images from 1973, 1986, 2002 and 2013 to identify and map changes in land-use classes over time. To understand...
  8. Changes in vegetation structure and aboveground biomass in response to traditional rangeland management practices in Borana, southern Ethiopia

    Changes in vegetation structure and aboveground biomass in response to traditional rangeland management practices in Borana, southern Ethiopia

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    This study aimed to determine vegetation structure, species diversity and aboveground herbaceous biomass and browse yields in Borana rangelands of southern Ethiopia. Sampling through random allocation of quadrats within replicated sample plots was undertaken in communally grazed areas, grazing enclosures...
  9. Grazing management that regenerates ecosystem function and grazingland livelihoods

    Grazing management that regenerates ecosystem function and grazingland livelihoods

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Adopting a systems view and regenerative philosophy can indicate how to regenerate ecosystem function on commercial-scale agro-ecological landscapes. Adaptive multi-paddock grazing management is an example of an approach for grazinglands. Leading conservation farmers have achieved superior results in ecosystem improvement,...
  10. A RULE-BASED ECOSYSTEM MODEL FOR THE MANAGEMENT OF LAKE ST LUCIA

    A RULE-BASED ECOSYSTEM MODEL FOR THE MANAGEMENT OF LAKE ST LUCIA

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Land transformations in the catchments of Lake St Lucia have altered the hydrology of the system and increased management is now needed to counteract these changes. There are several management options available, but prior to implementing them we must be...
