The study aimed to elucidating the seasonal variations of copper (Cu2+) and zinc (Zn2+) contents occurring in Atriplex canescens shrubs, as well as in surrounding soil. Cu and Zn concentrations were determined using X-ray fluorescence (XRF) spectrometry. Data were compared with those reported in...
Revegetation of marginalised rangelands using pastoral halophytes is considered an appropriate scientific and environmental approach to rehabilitation. Atriplex halimus L. (Amaranthaceae), A. mollis Desf. (Amaranthaceae), Cenchrus ciliaris L. (Poaceae) and Lotus creticus L. (Fabaceae) are...
In the Nama-Karoo, South Africa, rainfall and grazing by livestock are two important drivers of botanical composition. Summer rains are advantageous particularly to the grass layer, whereas the characteristic dwarf shrubs survive better than grasses during drought, and benefit from rainfall...
The objective of this study was to evaluate storage methods of cactus pear as a way of conservation for use in animal feeding. The randomised experimental design composed twelve treatments and three replications. Three cactus pear genotypes, Nopalea cochenillifera genotype Doce and Baiana and...
We investigated application of MaxEnt, a one-class classifier, in mapping the spatial distribution of Colophospermum mopane, Dichrostachys cinerea and Salvadora persica using drainage, elevation, slope, soil and Normalised Difference Vegetation Index as environmental variables. Model performance...
The potential for forage accumulated during periodic long rests to provide valuable winter grazing for livestock in heavily stocked communal rangelands in sourveld was assessed. In a continuously-grazed commonage at Ntshiqo in the Eastern Cape, South Africa, we measured seasonal patterns of...
