The effect of long-term fire treatments on invertebrates: results from experimental plots at Cathedral Peak, South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: C Uys M HamerThis study examined the impacts of different burning regimes (fire frequency and season) and fire history (time since last burn) on invertebrate morphospecies richness and abundance. The study was carried out in the Brotherton experimental plots at Cathedral Peak in... -
Impacts of trout on aquatic macroinvertebrates in three Drakensberg rivers in KwaZulu-Natal, South Africa
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: NA Rivers-Moore --- Centre for Water Resources Research, South Africa B Fowles --- , South Africa RJ Karssing --- , South AfricaGlobal literature suggests that trout, when introduced as alien species into local streams, have had deleterious impacts on aquatic community structure and function. Prior to defining management actions regarding trout in the rivers of the Ukhahlamba-Drakensberg Park (UDP), data are... -
Treatment Effects on Annual and Dry Period Streamflow at Cathedral Peak
Item type: Journal Article • Journal: South African Forestry Journal • Authors: J.M. Bosch --- Department of Forestry,Total annual streamflow and dry season flows of treated catchments at Cathedral Peak, Natal, were compared and related to those of index catchments. -
Effect of burn area on invertebrate recolonization in grasslands in the Drakensberg, South Africa
Item type: Journal Article • Journal: African Zoology • Authors: Charmaine Uys --- University of KwaZulu-Natal, South Africa Michelle Hamer --- University of KwaZulu-Natal, South Africa Robert Slotow --- University of KwaZulu-Natal, South AfricaOur study examined the short-term response of grassland invertebrate communities to fire in the South African Drakensberg, in relation to distance from the edge of a burn. We aimed to establish which species survive fire and the dynamics of the... -
Resolving the confusion: Amietia vertebralis and A. umbraculata tadpole morphology
Item type: Journal Article • Journal: African Zoology • Authors: Donnavan J.D. Kruger --- School of Environmental Sciences and Development, North-West University, Potchefstroom Campus, South Africa Ché Weldon --- School of Environmental Sciences and Development, North-West University, Potchefstroom Campus, South Africa Louis H. Du Preez --- School of Environmental Sciences and Development, North-West University, Potchefstroom Campus, South AfricaMorphological similarities between the tadpoles of Amietia umbraculata and A. vertebralis have led to confusion and incorrect descriptions and identifications in the literature. Based on 33 body measurements and ratios we revised the morphological descriptions of the tadpoles of the... -
Fire and the persistence, decline and extirpation of Protea roupelliae subsp. roupelliae trees in a montane grassland
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: François R Smith --- , South Africa Timothy G O’Connor --- , South Africa James E Granger --- , South Africa Angela J Beaumont --- , South AfricaWe investigated long-term changes, from 1979 to 2015, in the abundance of Protea roupelliae subsp. roupelliae trees growing in a montane grassland of the uKhahlamba-Drakensberg mountains. The study involved counting the numbers of adults and juveniles (saplings and seedlings) in... -
The effects of temperature on oxygen consumption in the lizard Pseudocordylus melanotus from Suikerbosrand Nature Reserve
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Suzanne McConnachie --- , , South AfricaIn reptiles, metabolic rate (MR) is affected by many different factors, including temperature, sex, body size and digestive state. Standard MR was measured for the lizard Pseudocordylus melanotus over a range of temperatures (20, 22, 25, 30 and 32°C). I...
