A study of animal production under different grazing regimes in the False Upper Karoo at Grootfontein
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: PCV du ToitThree systems of animal production on the fragile Karoo veld, i.e. multi-paddock rotational grazing, pauci-paddock rotational grazing and continuous grazing were studied. Of these systems, multi-paddock rotational grazing gave the best results with continuous stocking resulting in the worst. All... -
Forgiveness and the Well-Being of Members of the South African National Defence Force (SANDF): A Process for Discussion
Item type: Journal Article • Journal: Journal of Psychology in Africa • Authors: Gideon A.J. van Dyk --- Stellenbosch University,Africa is a continent of conflict, violence and war. South Africa, with a recent history of apartheid and current high percentage of crime is no exception. Members of the South African National Defence Force (SANDF) take part in peacekeeping operations... -
Spatial and temporal variations in densities of small fishes across different temporary floodplain types of the lower Okavango Delta, Botswana
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: N Siziba --- , Botswana MJ Chimbari --- , Botswana K Mosepele --- , Botswana H Masundire --- Department of Biological Sciences, BotswanaSmall-sized and juvenile fishes as well as physicochemical water parameters in various primary, secondary and rarely flooded temporary floodplains of the Okavango Delta were assessed during the different hydrological phases of the 2009–2010 flooding season. Small fishes were sampled in... -
Breeding ecology of Kori Bustard Ardeotis kori strunthiunculus in the Serengeti National Park
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Emmanuel C Mmassy --- Tanzania Wildlife Research Institute, Tanzania Robert D Fyumagwa --- Tanzania Wildlife Research Institute, Tanzania Kjetil Bevanger --- Norwegian Institute for Nature Research, Norway Eivin Røskaft --- Department of Biology, NorwayThe breeding ecology of the Kori Bustard Ardeotis kori strunthiunculus was studied in the plains of the Serengeti National Park, Tanzania in 2014 and 2015. Random transects were used to search for male courtship displays, nests, chicks and subadults. GPS... -
Patch-scale selection patterns of grazing herbivores in the central basalt plains of Kruger National Park
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Cyanne Young --- , South Africa Hervé Fritz --- , South Africa Erica AH Smithwick --- , United States of America Jan A Venter --- , South AfricaLarge herbivores form an essential component in the ecosystem, because of the impact that they have on their surrounding habitat. In this study, we aimed to evaluate some of the mechanisms behind how herbivores select forage at a patch scale... -
What grass characteristics drive large herbivore feeding patch selection? A case study from a South African grassland protected area
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Elena Mariotti --- , South Africa Francesca Parrini --- , South Africa Cornelius J Louw --- , South Africa Jason P Marshal --- , South AfricaThe coexistence of a large herbivore community depends on the degree of overlap in the resource used by the different species composing it. We investigated the role of grass greenness, height, biomass and feeding patch status on feeding patch selection... -
High-intensity fire experiments to manage shrub encroachment: lessons learned in South Africa and the United States
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Rheinhardt Scholtz --- , United States Victoria M Donovan --- , United States Tercia Strydom --- , South Africa Carissa Wonkka --- , United States Urs P Kreuter --- , United States William E Rogers --- , United States Charles Taylor --- , United States Izak PJ Smit --- , South Africa Navashni Govender --- , South Africa Winston Trollope --- , South Africa Dillon T Fogarty --- , United States Dirac Twidwell --- , United StatesHuman alteration of fire regimes is a hallmark of the Anthropocene; yet few studies have fully explored the implications of utilizing high-intensity fires in grasslands and savannas to manage shrub encroachment. Decades of fire research in South Africa inspired a...
