Anthropogenic light, noise, and vegetation cover differentially impact different foraging guilds of bat on an opencast mine in South Africa
(Frontiers, 2022)Bats are known to be sensitive to changes in their environment. The impact of natural vegetation cover, artificial light intensity and noise (dBA) were investigated on the bat community on the opencast Venetia diamond mine ... -
Geographic distribution and habitat selection in the berg adder, Bitis atropos (serpentes, viperidae) on the Mpumalanga escarpment, and the consequences for conservation
(University of the Free State, 2019-06-01)Understanding how species use geographic space is foundational to ecology, biogeography and conservation biology. However, such essential geographic information remains unavailable for many species. This is especially true ... -
Studies on stalk borers of maize and sorghum in Lesotho
(University of the Free State, 1998-11)English: Investigations on various aspects of stalk borers of maize and sorghum were conducted in Lesotho during the 1995/96, 1996/97 and 1997/98 growing seasons. Aspects investigated were their distribution and relative ... -
Blood parasites of Free State and Lesotho reptiles
(University of the Free State, 2003-07)English: The study of blood parasites of reptiles is a relatively new and unexplored field of research in South Africa. The Free State province and the Lesotho highlands provide a range of reptiles in which their ... -
