Iodinated dyes 10c and 10d had IC50 values of 11.6 and 8.2 μM, respectively, and non-iodinated dyes 9c and 9d had IC50 values of 12.5 and 19.2 μM. The heavy atom effect associated with the iodine atoms increases the singlet oxygen quantum yield and enhances the suitability of the dyes for photodynamic therapy.]]> Sat 20 Apr 2024 18:23:13 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72154 Sat 20 Apr 2024 17:27:17 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72153 5-meters depth) and (0.5-meter depth) from the water surface at each lake during summer and winter season. The results were consistent with our hypothesis that both phytoplankton and aquatic macroinvertebrate species composition were influenced by physico-chemical parameters and that the differences in salinity concentration and aquatic vegetation between CL, FIL, and SIL were the driving factors for phytoplankton and aquatic macroinvertebrate species composition. In summary, one hundred and twenty-two phytoplankton taxa were collected and identified during this study, belonging to seven Phyla which included Chlorophyta, Bacillariophyta, Cyanophyta, Chrysophyta, Dinophyta, Euglenophyta, and Cryptophyta. The most abundant phytoplankton groups were Bacillariophyta and Chlorophyta. Phytoplankton relative taxa abundance, Pielou’s evenness, taxa richness, and Shannon diversity were significantly different between lake types. Aquatic macroinvertebrates, on the other hand, summed up to 10 orders, 67 families, and 80 taxa. The most abundant group were the order Coleoptera, Hemiptera, Odonata, and Gastropoda. Aquatic macroinvertebrate relative taxa abundance, taxa richness, and Shannon diversity were also significantly different between lake types. Aquatic macroinvertebrate relative taxa abundance, Pielous evenness, and Shannon diversity index were not significant between seasons, and only taxa richness was significant. Canonical analysis of principal coordinates (CAP) results further showed unique and distinct phytoplankton and aquatic macroinvertebrates community composition between lake types. The present study provides baseline biodiversity inventory (or species list) for important lake ecosystems biological indicators i.e., phytoplankton and aquatic macroinvertebrates and species composition in relation to lake type for six freshwater lakes in South Africa. Furthermore, the study provides empirical evidence that will inform policy and the development of management strategies for freshwater lakes in South Africa which is currently missing. The current study will also contribute to the next National Biodiversity Assessment Report (2024), concerning the freshwater lakes biological data deficiency noted in the previous NBA (2018) report. The study will also fill up the gaps to better understand species composition in lake systems and how they function which is currently limited.]]> Sat 20 Apr 2024 17:20:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72142 Sat 20 Apr 2024 13:15:15 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72141 Sat 20 Apr 2024 13:14:24 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72140 Sat 20 Apr 2024 13:01:02 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72139 Sat 20 Apr 2024 12:47:17 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72138 Sat 20 Apr 2024 12:40:40 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72137 Sat 20 Apr 2024 12:33:12 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72136 Sat 20 Apr 2024 12:25:51 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72135 Sat 20 Apr 2024 12:19:21 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72134 Sat 20 Apr 2024 12:18:37 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72133 Sat 20 Apr 2024 12:12:41 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72126 Sat 20 Apr 2024 11:09:04 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72123 Sat 20 Apr 2024 10:40:47 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72122 Sat 20 Apr 2024 10:27:01 SAST ]]>
