  1. Wildlife roadkill patterns on a major highway in northern Tanzania

    Wildlife roadkill patterns on a major highway in northern Tanzania

    Item type: Journal Article • Journal: African Zoology
    Despite expanding road networks, there is limited understanding of the effects of roads on wildlife in East Africa. We present a baseline survey and describe the patterns of roadkill in the Tarangire–Manyara ecosystem of Tanzania. A 75 km stretch of...
  2. The Use of Roots to Test N, P and K Deficiencies in <em>Eucalyptus</em> Nutrition

    Item type: Journal Article • Journal: South African Forestry Journal
    Bioassays have been developed which can provide diagnostics of the nutritional status of trees. They measure the flux of N, P or Rb for K into roots from standard solutions where the rate of influx is inversely related to nutrient...
  3. Postflexion and transforming larvae of <em>Gonorynchus gonorynchus</em> (Linnaeus, 1766)

    Postflexion and transforming larvae of <em>Gonorynchus gonorynchus</em> (Linnaeus, 1766)

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Postflexion larvae of Gonorynchus gonorynchus, previously undocumented, are described from the South-East Atlantic. Comparisons with descriptions of larval G. abbreviatus and larvae of another, still unidentified, species of Gonorynchus suggest slight to conspicuous differences in pigmentation between species.
  4. Development of a doubled haploid mapping population and linkage map for the bread wheat cross Kariega × Avocet S

    Development of a doubled haploid mapping population and linkage map for the bread wheat cross Kariega × Avocet S

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A doubled haploid wheat population of 150 lines was constructed from the F1 of a cross between cultivars Kariega and Avocet S using the wheat-maize technique. Segregation and linkage analysis of 203 DNA markers, two storage protein markers and the...
  5. Effects of soil surface management practices on soil and tree parameters in a ‘Cripps Pink’/M7 apple orchard 1. Mineral nutrition

    Effects of soil surface management practices on soil and tree parameters in a ‘Cripps Pink’/M7 apple orchard 1. Mineral nutrition

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Effects on soil, leaf and fruit element concentrations of organic (compost, straw mulch and hand weeding) and integrated (inorganic fertilisers and herbicide usage; IP) soil surface management practices in the tree rows, in combination with weed covers, cover crops and...
  6. Effects of soil surface management practices on soil and tree parameters in a ‘Cripps Pink’/M7 apple orchard 2. Tree performance and root distribution

    Effects of soil surface management practices on soil and tree parameters in a ‘Cripps Pink’/M7 apple orchard 2. Tree performance and root distribution

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Effects of integrated production (IP) and organic-acceptable soil surface management practices were investigated in a ‘Cripps Pink’/M7 apple orchard in the Elgin area, South Africa. Work row treatments included cover crops, weeds and straw mulch. In the IP tree rows,...
