  1. Extension of the diet of an extreme foraging specialist, the aardwolf (<em>Proteles cristata</em> )

    Extension of the diet of an extreme foraging specialist, the aardwolf (<em>Proteles cristata</em> )

    Item type: Journal Article • Journal: African Zoology
    The aardwolf, Proteles cristata, is a highly specialized myrmecophagous carnivore that feeds almost exclusively on termites of the genus Trinervitermes. Here we report data from an ongoing analysis of aardwolf diet, where we documented remains of sun spiders and scorpions...
  2. An index of spring diet in the common flat lizard, <em>Platysaurus intermedius wilhelmi</em>

    An index of spring diet in the common flat lizard, <em>Platysaurus intermedius wilhelmi</em>

    Item type: Journal Article • Journal: African Journal of Herpetology
    Flat lizards of the genus Platysaurus are primarily insectivorous, but some species are omnivorous, eating significant amounts of plant material. The common flat lizard, P. intermedius, is thought to forage on arthropods, flowers, leaves and fruit. However, this assertion is...
  3. Veld condition and animal performance: Application of an optimal foraging model

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An optimal foraging model was used to predict food ingestion rate, food digestion rate and animal energy gains relative to requirements as functions of dietary composition. Energy gains were maximized by ranking food types in order of their effective value,...
  4. A review of orange roughy <em>Hoplostethus atlanticus</em> fisheries, estimation methods, biology and stock structure

    A review of orange roughy <em>Hoplostethus atlanticus</em> fisheries, estimation methods, biology and stock structure

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Orange roughy Hoplostethus atlanticus are unusual fish. They form dense aggregations that have fuelled lucrative fisheries at great depths (600–1 400 m), especially off Namibia, New Zealand and Australia. They are thought to be very long-lived (>100 years, maturity at...
  5. Adaptability of great cormorants <em>Phalacrocorax carbo</em> in a coastal environment demonstrated by their exploitation of introduced prey species and use of artificial breeding sites

    Adaptability of great cormorants <em>Phalacrocorax carbo</em> in a coastal environment demonstrated by their exploitation of introduced prey species and use of artificial breeding sites

    Item type: Journal Article • Journal: South African Journal of Marine Science
    An analysis of the contents of regurgitations of great cormorant Phalacrocorax carbo chicks at two coastal colonies in South Africa, one on an offhore island (St Croix) and the other at a saltworks in an estuary (Swartkops), revealed that the...
  6. DIET AND REPRODUCTIVE ACTIVITY OF THE ESTUARINE ROUNDHERRING <em>GILCHRISTELLA AESTUARIA</em> IN CUBHU, A FRESHWATER COASTAL LAKE IN NORTHERN NATAL, SOUTH AFRICA

    DIET AND REPRODUCTIVE ACTIVITY OF THE ESTUARINE ROUNDHERRING <em>GILCHRISTELLA AESTUARIA</em> IN CUBHU, A FRESHWATER COASTAL LAKE IN NORTHERN NATAL, SOUTH AFRICA

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    A study of the diet and reproductive activity of Gilchristella aestuaria revealed that active gonads were present throughout the year. The main breeding season appeared to be from spring through to autumn with two distinct peaks occurring from August to...
  7. COMPARISON OF FISH GONADS AND FISH MEAL AS MAJOR COMPONENTS IN THE DIETS OF YOUNG AFRICAN SHARPTOOTH CATFISH, <em>CLARIAS GARIEPINUS</em> (BURCHELL)

    COMPARISON OF FISH GONADS AND FISH MEAL AS MAJOR COMPONENTS IN THE DIETS OF YOUNG AFRICAN SHARPTOOTH CATFISH, <em>CLARIAS GARIEPINUS</em> (BURCHELL)

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    The replacement of fish-meal (two sources, arbitrarily designated FMA and FMB), with either freeze dried (GVD) or oven dried (GOD) gonads of Clarias gariepinus in a starter diet for larvae of this species, was tested. No significant difference in larval...
  8. Effect of <em>Acacia tortilis</em> pods on intake, digestibility and nutritive quality of goat diets in southwestern Eritrea

    Effect of <em>Acacia tortilis</em> pods on intake, digestibility and nutritive quality of goat diets in southwestern Eritrea

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Fresh Acacia tortilis pods were mixed with low quality native grass hay to form the following five rations: 100% hay (T1), 25% pods and 75% hay (T2), 50% pods and 50% hay (T3), 75% pods and 25% hay (T4) and...
  9. The nutritional value of <em>Zizyphus spina-christi</em> for goat production among the pastoralists of Kalu district, South Wello, Ethiopia

    The nutritional value of <em>Zizyphus spina-christi</em> for goat production among the pastoralists of Kalu district, South Wello, Ethiopia

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Fifteen yearling goats of similar weight were used to evaluate the potential of Zizyphus spina-christi leaves as a supplement to goats fed on Cynodon dactylon grass. Animals were randomly assigned to five feeding regimes and individually stall-fed for a preliminary...
  10. Seasonal botanical and chemical composition of sheep and goat diets on a common range in eastern Africa

    Seasonal botanical and chemical composition of sheep and goat diets on a common range in eastern Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The botanical and chemical composition, intake and digestibility of local sheep (Ovis aries) and goat (Capra hirtus) diets were evaluated over the wet (growing) and dry (dormant) seasons. Diet botanical composition was related to the vegetation composition on the range...
