Hot days are associated with short-term adrenocortical responses in a southern African arid-zone passerine bird

Relatively little effort has been directed towards elucidating the role of physiological stress pathways in mediating avian responses to global heating. For free-ranging southern pied babblers, Turdoides bicolor, daily maximum air temperatures (Tmax) between ∼35 and ∼40°C result in reduced foraging efficiency, loss of body mass and compromised breeding success. We tested the hypothesis that very hot days are experienced as stressors by quantifying relationships between Tmax and faecal glucocorticoid metabolite (fGCM) levels in naturally excreted droppings. On days when Tmax<38°C, fGCM levels were independent of Tmax (mean±s.d. 140.25±56.92 ng g−1 dry mass). At Tmax>38°C, however, fGCM levels increased linearly with Tmax and averaged 190.79±70.13 ng g−1 dry mass. The effects of Tmax on fGCM levels did not carry over to the following morning, suggesting that very hot days are experienced as acute stressors.The DSI-NRF Centre of Excellence at the FitzPatrick Institute for African Ornithology, the University of Cape Town, the Ernest Oppenheimer Memorial Trust, the British Ornithologists’ Union, the Australian Research Council and the National Research Foundation of South Africa.http://jeb.biologists.org2022-05-15am2022Mammal Research InstituteZoology and Entomolog

Integrating African Traditional Health Knowledge and Practices into Health Sciences Curricula in Higher Education: An Imbizo

Traditional health knowledge and practices remain the primary source of health services for most African communities. Despite this, the training of health professionals in South African higher education institutions remains underpinned on paradigms based on Western medicine, adversely perpetuating health disparities and widening the gap between health professionals and African health service users. This research describes the views of African traditional knowledge holders, traditional health practitioners, health sciences academics, and nursing students on how African traditional health knowledge and practices can be integrated into health sciences curricula. In this qualitative study, we purposively selected a panel of experts as participants and collected data via a discussion forum. Ideas that stood out from the discussions include the nature of transformation as starting from within, barriers to the co-existence of African and biomedical health systems, and strategies to facilitate integration. This venture has revealed that the successful integration of African traditional health knowledge and practices into existing nursing curricula will require a concerted effort from all stakeholders in order to transform and recognise the value of African traditional medicine. Lessons learnt from adopting an imbizo approach for discussions include improved collaboration and the levelling of power differentials. We recommend that more studies on decolonisation within the African context adopt this methodology to ascertain and strengthen its viability.http://www.tandfonline.com/loi/rars202021-05-18hj2020Nursing Scienc
