  2. Taxonomy, phylogeny and biogeography of cisticolas (Cisticola spp.) by Davies, Owen R

    Published 2015
    “…Most of the mean divergence date estimates correlated with periods of climate variability and episodes during which there is evidence for high lake levels in Africa, rather than correlating with Plio-Pleistocene glaciation, offering evidence that open habitats may have become fragmented during extremes of both arid and humid climates.…”

    Published 2016
    “…Processes driving movement can occur across multiple spatiotemporal scales and have important consequences for the structure and dynamics of populations, communities and ecosystems. …”

  7. Individual contributions to group behaviour in the cooperatively breeding southern ground-hornbill Bucorvus leadbeateri by Middleton, Kyle-Mark

    Published 2023
    “…In birds, cooperative breeding is found mainly in harsh regions with greater environmental variability, such that individuals might do better to help relatives than attempt to breed themselves. …”

  9. Through the keyhole: Ethnographic analysis of cyber violence in Egypt by Fouda, Radwa

    Published 2019
    “…It focuses mainly on individual-to-individual perpetration of violence, how, when and why people variably define unsolicited intervention with their data as "violence", and how, when and why, they choose other notions to define such incident(s). …”

  10. The use of operational harmful algal bloom monitoring systems in South Africa to assess long term changes to bloom occurrence & impacts for aquaculture by Mtetandaba, Aphiwe

    Published 2021
    “…For this study, high-resolution satellite remote sensing observations from 16 years of MODIS-Aqua (1 km) and one month of Sentinel-3 OLCI (300 m), using regionally optimised blended algorithms, were used to investigate the spatial distribution and temporal variability of chlorophyll-a (Chl-a) along the south coast of South Africa. …”

  11. An exploratory study of financial access along the renewable energy sector value chain: the case of SMMEs in South Africa by Mali, Nwabisa

    Published 2025
    “…The findings highlighted that financial stability was closely tied to project scale, with larger-scale projects providing more consistent revenue streams, while SMMEs in niche sectors often faced revenue variability. Financial management practices were essential for sustaining operations, particularly in managing costs and planning for fluctuating revenues. …”

  15. Characterising the response of the mixed and the transitional layers to the passage of storms in the Sub-Antarctic Zone by Mpalweni, Ayanda

    Published 2020
    “…The mixed-layer depth (MLD) is used widely as proxy for vertical extent of upper-ocean mixing, with the assumption that it integrates the variability of atmospheric forcing. Recent studies have shown that this shear-driven mixing associated with storms can actually extend below the base of the MLD into the transitional layer (TL). …”

  17. The representation of the Kalahari Thermal Low and its induced circulations over southern Africa in observations and models by Monyela, Bellinda Mashoene

    Published 2025
    “…This teleconnection is explained by the leading mode of variability, but it is controlled more by the heat dome mechanism rather than by the advection of the mid-tropospheric dry air into the convective region. …”
