  1. Sexual cycle and seasonal expression of testosterone (T) in the testes of <em>Sclerophrys mauritanica</em> (Schlegel, 1841)

    Sexual cycle and seasonal expression of testosterone (T) in the testes of <em>Sclerophrys mauritanica</em> (Schlegel, 1841)

    Item type: Journal Article • Journal: African Journal of Herpetology
    Sclerophrys mauritanica is an anuran amphibian found in the wetlands of Beni-belaid, Jijel, Algeria. The animals are constrained by wet (from September until May) and dry (from June until August) seasons, however, the sexual cycle of males is continuous (all...
  2. The vulnerable Osprey breeding population of the Al Hoceima National Park, Morocco: present status and threats

    The vulnerable Osprey breeding population of the Al Hoceima National Park, Morocco: present status and threats

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    In the Mediterranean, most areas belonging to the initial distribution range of the Osprey Pandion haliaetus have been lost and local populations have disappeared in recent decades because of persecution. Even though direct management actions have allowed local partial recovery,...
  3. Challenges to implementing the food-based dietary guidelines in the South African primary school curriculum: a qualitative study exploring the perceptions of principals and curriculum advisors

    Challenges to implementing the food-based dietary guidelines in the South African primary school curriculum: a qualitative study exploring the perceptions of principals and curriculum advisors

    Item type: Journal Article • Journal: South African Journal of Clinical Nutrition
    Objectives: The South African food-based dietary guidelines (FBDG) were developed and implemented to promote healthy lifestyles in the population along with preventing non-communicable diseases and other forms of diet-related illness. The FBDG were recommended for implementation within the national school...
  4. Geno-Phenotypic Regression and Juvenile-Mature Correlations: Methodological Tools for Clonal Selection of <em>Eucalyptus</em> Hybrids in Congo

    Item type: Journal Article • Journal: South African Forestry Journal
    This paper discusses different ways to improve clonal selection and clonal variety propagation for the industrial plantations in Congo.
  5. A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A field experiment was conducted on a Normandien clay loam (Plinthic Paleudult) to compare the acid tolerance of 48 commercially grown maize (Zea mays L.) cultivars. Cultivars were compared in terms of grain yield, plant height and leaf Al content...
  6. Comparison of methods for estimating cation exchange capacity of orchard soils

    Comparison of methods for estimating cation exchange capacity of orchard soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Various methods for estimating soil cation exchange capacity (CEC) were compared. CEC obtained by the sum of extractable cations and the Adams-Evans buffer method were considerably higher than those obtained by saturation and displacement of either NH4 + or Na+...
  7. Application of Partial Least Squares regression to relate tastiness of boiled potatoes to chemical and physical tests

    Application of Partial Least Squares regression to relate tastiness of boiled potatoes to chemical and physical tests

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Partial Least Squares regression (PLS) was used to understand the relationship between 15 sensory attributes of potatoes boiled in their skins as dependent variables (Y), and six objective (chemical and physical) measurements as the independent variables (X). The ARC-Sensory Analysis...
