  1. Vertical distribution of living mangrove foraminifera from KwaZulu-Natal, South Africa

    Vertical distribution of living mangrove foraminifera from KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Modern foraminiferal assemblage zones can be used to reconstruct palaeo sea levels when applied to fossil foraminifera down a sediment core. Previous intertidal foraminiferal studies have predominantly focused on assemblages in surface sediments (0–1 cm), with the rationale that surface...
  2. Spatial pattern and variability of soils in a granite landscape, north-east of Nelspruit

    Spatial pattern and variability of soils in a granite landscape, north-east of Nelspruit

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Morphological and selected chemical and granulometric properties of eleven soil profiles occurring on five hillslope sites (midslope, upper footslope, mid-footslope, lower footslope and valley bottom) were determined in order to evaluate the spatial pattern and variability of soils in a...
  3. Spatial pattern and variability of soil and hillslope properties in a granitic landscape 1. Pretoriuskop area

    Spatial pattern and variability of soil and hillslope properties in a granitic landscape 1. Pretoriuskop area

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Characteristics of nine hillslope profiles and selected properties of 69 soil profiles were determined in order to evaluate the spatial pattern and variability of soil and hillslope properties in a granitic area near Pretoriuskop, Kruger National Park. A transect design...
  4. Spatial pattern and variability of soil and hillslope properties in a granitic landscape 2. Pretoria—Johannesburg area

    Spatial pattern and variability of soil and hillslope properties in a granitic landscape 2. Pretoria—Johannesburg area

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Using a transect design, a detailed examination was made of nine hillslopes and 64 soil profiles in the granitic area between Johannesburg and Pretoria to assess the spatial pattern and variability of soil and hillslope properties. The land surface was...
  5. A contiguous-quadrat sampling exercise in a shrub-invaded grassland patch: size matters but biggest is not best

    A contiguous-quadrat sampling exercise in a shrub-invaded grassland patch: size matters but biggest is not best

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    We attempted to ascertain the most effective sample size for monitoring serial changes in the herbaceous layer of fragmented and neglected grasslands that are responding to annual veld burning. We conducted a sampling exercise in a coastal grassland invaded by...
  6. Optimisation of underwater visual census and controlled angling methods for monitoring subtidal temperate reef fish communities

    Optimisation of underwater visual census and controlled angling methods for monitoring subtidal temperate reef fish communities

    Item type: Journal Article • Journal: African Journal of Marine Science
    Standardised sampling protocols for monitoring fish stocks are essential to assess changes in stock status and provide a means to evaluate the effectiveness of fisheries management measures, such as marine protected areas (MPAs). This study aimed to optimise two standard...
  7. Diel effects on bottom-trawl survey catch rates of shallow- and deep-water Cape hakes <em>Merluccius capensis</em> and <em>M. paradoxus</em> off Namibia, using solar zenith angle

    Diel effects on bottom-trawl survey catch rates of shallow- and deep-water Cape hakes <em>Merluccius capensis</em> and <em>M. paradoxus</em> off Namibia, using solar zenith angle

    Item type: Journal Article • Journal: African Journal of Marine Science
    Diel patterns in survey trawl catches for the Cape hakes Merluccius capensis and M. paradoxus off Namibia were studied in order to examine the effect of diel bias on catchability, and its implication for survey abundance estimation and the consistency...
  8. Comparison of distance sampling estimates to a known population size of Ant-eating Chats <em>Myrmecocichla formicivora</em>

    Comparison of distance sampling estimates to a known population size of Ant-eating Chats <em>Myrmecocichla formicivora</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Line-transect sampling was used to obtain abundance estimates of an Ant-eating Chat Myrmecocichla formicivora population to compare these with the true size of the population. The population size was determined by a long-term banding study, and abundance estimates were obtained...
  9. Comparative performance of four survey methods for assessing Lilian’s Lovebird abundance in Liwonde National Park, Malawi

    Comparative performance of four survey methods for assessing Lilian’s Lovebird abundance in Liwonde National Park, Malawi

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Monitoring abundance of threatened species is important for conservation planning. Lilian’s Lovebird Agapornis lilianae is a near-threatened small parrot found in mopane Colophospermum mopane woodland. Its population has not been investigated in any part of its range. We investigated the...
