Many sites in the bay, especially the atypical site at Cape Recife, exhibit higher than the average pH levels (>8.04), suggesting that pH variability may be biologically driven. This is further evidenced by high diurnal variability in pH (~0.55 pH units). Although the specific drivers of the high pH variability in Algoa Bay could not be identified, baseline carbonate chemistry conditions were identified, which is necessary information to design and interpret biological experiments. Long-term, continuous monitoring is required to improve understanding of the drivers of pH variability in understudied coastal regions, like Algoa Bay. A local fisheries species, D. capensis, was selected as a model species to assess the impacts of future OA scenarios in Algoa Bay. It was hypothesized that this temperate, coastally distributed species would be adapted to naturally variable pH conditions and thus show some tolerance to low pH, considering that they are exposed to minimum pH levels of 7.77 and fluctuations of up to 0.55 pH units. Laboratory perturbation experiments were used to expose early postflexion stage of D. capensis to a range of pH treatments that were selected based on the measured local variability (~8.0–7.7 pH), as well as future projected OA scenarios (7.6–7.2 pH). Physiological responses were estimated using intermittent flow respirometry by quantifying routine and active metabolic rates as well as relative aerobic scope at each pH treatment. The behavioural responses of the larvae were also assessed at each pH treatment, as activity levels, by measuring swimming distance and speed in video-recording experiments, as well as feeding rates. D. capensis had sufficient physiological capacity to maintain metabolic performance at pH levels as low as 7.27, as evidenced by no changes in any of the measured metabolic rates (routine metabolic rate, active metabolic rate, and relative aerobic scope) after exposure to the range of pH treatments (8.02–7.27). Feeding rates of D. capensis were similarly unaffected by pH treatment. However, it appears that subtle increases in activity level (measured by swimming distance and swimming speed experiments) occur with a decrease in pH. These changes in activity level were a consequence of a change in behaviour rather than metabolic constraints. This study concludes, however, that based on the parameters measured, there is no evidence for survival or fitness related consequences of near future OA on D. capensis. OA research is still in its infancy in South Africa, and the potential impacts of OA to local marine resources has not yet been considered in local policy and resource management strategies. Integrating field monitoring and laboratory perturbation experiments is emerging as best practice in OA research. This is the first known study on the temperate south coast of South Africa to quantify local pH variability and to use this information to evaluate the biological response of a local species using relevant local OA scenarios as treatment levels for current and near future conditions. Research on local conditions in situ and the potential impacts of future OA scenarios on socio-economically valuable species, following the model developed in this study, is necessary to provide national policy makers with relevant scientific data to inform climate change management policies for local resources.]]> Thu 29 Sep 2022 12:42:34 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71031 Thu 25 Apr 2024 15:54:50 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71139 Thu 18 Jan 2024 09:15:40 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:56073 Thu 15 Sep 2022 12:52:58 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42199 Thu 13 Jul 2023 12:40:08 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:74137 Thu 11 Jul 2024 12:47:20 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44419 Thu 11 Aug 2022 12:31:46 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:42819 Thu 11 Aug 2022 06:50:48 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:44452 Thu 09 Sep 2021 12:10:28 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:66353 Thu 09 May 2024 06:18:45 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:65792 Sun 21 Jan 2024 14:23:44 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:58199 Sun 21 Apr 2024 21:38:03 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:58196 87% had one (or fewer) test missing. Results suggested a similar factor structure to prior PennCNB studies in Western contexts, and expected age and sex effects were apparent. Furthermore, a similar profile of schizophrenia was observed, with neurocognitive deficits most pronounced for executive functions, especially attention, as well as memory, social cognition, and motor speed relative to complex cognition and sensorimotor speed. Conclusions: Results support the feasibility of implementing a culturally adapted computerized neurocognitive battery in sub-Saharan African settings and provide evidence supporting the concurrent validity of the translated instrument. Thus, the PennCNB is implementable on a large scale in non-Western contexts, shows expected factor structure, and can detect cognitive deficits associated with neuropsychiatric disorders. Obtaining valid measures of cognition by nonspecialized proctors is especially suitable in resource-limited settings, where traditional testing is prohibitive.
