Basking behaviour in the rock hyrax (Procavia capensis) during winter
Item type: Journal Article • Journal: African Zoology • Authors: Kelly J. Brown --- School of Biological and Conservation Sciences, University of KwaZulu-Natal, South Africa Colleen T. Downs --- School of Biological and Conservation Sciences, University of KwaZulu-Natal, South AfricaBasking is a behaviour frequently observed in the rock hyrax (Procavia capensis) during winter that supposedly plays a significant role in rewarming from nocturnal hypothermia. This behaviour, together with changes in body temperature and changes in black bulb temperatures (Tbb)... -
Operator work-related musculoskeletal disorders during forwarding operations in South Africa: an ergonomic assessment
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Kudakwashe Phairah --- Department of Plant Production and Soil Science, Forest Science Postgraduate Programme, South Africa Michal Brink --- Department of Plant Production and Soil Science, Forest Science Postgraduate Programme, South Africa Paxie Chirwa --- Department of Plant Production and Soil Science, Forest Science Postgraduate Programme, South Africa Andrew Todd --- Department of Human Kinetics and Ergonomics, South AfricaForest machine operators are still experiencing work-related musculoskeletal disorders (WMSDs) despite extensive mechanisation and modernisation of harvesting systems. However, paucity of local ergonomics research and technology transfer problems may affect the use of mechanised systems in South Africa. Consequently, this... -
Behavioural responses to air temperature change in helmeted guineafowl Numida meleagris
Item type: Journal Article • Journal: African Zoology • Authors: Johann H van Niekerk --- University of South Africa, South Africa Marta Rodríguez-Rey --- Universidad de Alcalá, Forest Ecology and Restoration Research Group (FORECO), Spain Fabián Casas --- Universidad de Granada, Spain Giovanni Forcina --- Global Change Ecology and Evolution Research Group (GloCEE)/Soil Biology and Subterranean Ecosystems Research Group (GIBSES), SpainDeciphering the behavioural responses of helmeted guineafowl Numida meleagris (Linnaeus, 1758) to temperature variation is key to understanding its eco-ethology and implementing sound management strategies. Here, we tested the ‘warmer together’ hypothesis, which states that thermoregulatory cost reduction (i.e. body...
