    Monitoring of seabirds in the Benguela upwelling system: can seabirds be used as indicators and predictors of change in the marine environment?

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Historical and contemporary data on Benguela seabirds assumed to be responsive to changes in food availability are reviewed as potential indicators and predictors of change in the ecosystem. Cyclic variations in the annual yields of seabird products evident at decadal...

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Seedling emergence, survival and species composition were recorded on vegetation subjected to seven practicably feasible soil and defoliation treatments. Soil disturbance, with defoliation removal, produced the greatest number of emergents; these also had the best survivorship compared to other treatments...
