    The social correlates of self-directed behaviour and faecal glucocorticoid levels among adult male olive baboons (<em>Papio hamadryas anubis</em>) in Gashaka-Gumti National Park, Nigeria

    Item type: Journal Article • Journal: African Zoology
    Sociality confers many benefits to gregarious animals, but group-living does not come without associated costs. Social living can cause anxiety, which if prolonged can lead to stress. We investigate correlates of anxiety and stress among wild adult male olive baboons...
  2. Effects of season of burn on shrub survival, regeneration and structure in the Natal Drakensberg

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Four shrub species which tend to invade unburnt grassland were studied in field‐burning trials at Cathedral Peak in the Natal Drakensberg.
  3. Plant palatability assessment and its implications for plant‐herbivore relations

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An objective method used to assess the palatability of the foliage of woody plant species to kudus, impalas and goats is described. Observations were made on the feeding behaviour of tame animals in the Nylslvey Nature Reserve in northern Transvaal...
  4. Pollination activity and behaviour of honeybees (<em>Apis mellifera</em> L.) in commercial sunflower in the Transvaal

    Pollination activity and behaviour of honeybees (<em>Apis mellifera</em> L.) in commercial sunflower in the Transvaal

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Honeybee foraging activity in commercial sunflower fields was studied at Settlers, 100 km north of Pretoria. Foraging activity, which was studied by means of the conventional strip count method, commenced after sunrise and reached a peak of 38 foragers per...

    Fish response to the annual flooding regime in the Kavango River along the Angola/Namibian border

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The results of the first seasonal survey of the fish of the Kavango River flood-plain along the Angola/Namibia border are reported. The river experiences peak flooding from February through June, with the 375-km long floodplain extending up to 5 km...
  7. CLEANING BEHAVIOUR BETWEEN THE CICHLID FISH <em>TILAPIA RENDALLI FENDALLI</em> BOULENGER 1896 AND THE CYPRINID, <em>LABEO CYLINDRICUS</em> PETERS, 1852

    CLEANING BEHAVIOUR BETWEEN THE CICHLID FISH <em>TILAPIA RENDALLI FENDALLI</em> BOULENGER 1896 AND THE CYPRINID, <em>LABEO CYLINDRICUS</em> PETERS, 1852

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    A case of interspecific cleaning behaviour is described between a cichlid host Tilapia rendalli rendalli and a Juvenile cyprinid Labeo cylindricus, in captivity. The host fish initiated the cleaning behaviour with a ‘head down’ display.

    BEHAVIOUR OF A RADIO-TAGGED <em>TILAPIA RENDALLI</em> BOULENGER IN LAKE NGEZI, ZIMBABWE

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The behaviour of a single specimen of Tilapia rendalli Boulenger was observed June through October 1986 in Lake Ngezi, Zimbabwe, by the use of a surgically-implanted radiotransmitter. The individual displayed a distinct homing response on two occasions, returning to the...

    Cattle diet selection during the hot-dry season in a semi-arid region of Namibia

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The northern Kalahari Desert is dominated by Terminalia sericea savanna woodland and a sparse herbaceous layer. Range ecologists regard T. sericea as a major encroaching species and that such encroachment represents a cost to cattle production. In contrast, pastoralists regard...
