Drought was perceived by a sizeable proportion (>70%) of small-scale farmers as a very serious environmental challenge with adverse socio-economic repercussions on land-based activities. Livestock losses and crop failure were the key impacts reported by small-scale farmers in both rural and urban settings. About 86% of respondents across the sample reported declines in crop yields, with significantly more farmers in rural sites (45%) than urban sites (31%) reporting so. A substantial proportion of farmers across the sample (93%) reported drought response strategies relating to livestock and crop production, such as changing of farming practices, use of drought-resistant crops and government support, with slight differences in the proportion of farmers reporting so between urban (89 %) and rural (95 %) sites. Concerning government support, most respondents (>70%) stated that they were dissatisfied, with slightly more respondents in urban areas (77%) than in rural (70%) areas reporting so. Overall, the results of this study suggest a minimal response capacity of small-scale farmers to droughts in both rural and urban settings due to socio-economic and administrative factors, which calls for the need for drought-response strategies to build adaptive capacity for small-scale farmers. Turning to close cooperation between different stakeholders, such as local farmers, government officials, practitioners, and scientists might allow co-production of knowledge needed to inform drought response strategies. In some instances, attention needs to be given to farmers who are more vulnerable than others.]]> Sun 21 Apr 2024 09:53:43 SAST ]]> Distribution and habitat preferences of marine megafauna in Nosy Be, Madagascar Sun 21 Apr 2024 08:48:55 SAST ]]> Natural Language Processing with machine learning for anomaly detection on system call logs Sun 21 Apr 2024 08:41:54 SAST ]]> Application of web design techniques and best practices in implementing web development, maintenance and enhancement of RUBi websites and web application systems Sun 21 Apr 2024 08:14:12 SAST ]]> Identification of novel Arf1 GTPase inhibitors for cancer target validation Sun 21 Apr 2024 07:52:16 SAST ]]> Investigation of brewery waste grains and microbial fuel cells as value-additive technologies improving solvent production yields in Clostridium acetobutylicum (ATCC 824) fermentation Sun 21 Apr 2024 07:31:41 SAST ]]> Benchmarking tax practitioner regulation in Zimbabwe and South Africa against German best practice Sat 24 Feb 2024 19:25:44 SAST ]]> Liquidity shocks and capital market efficiency in South Africa Sat 24 Feb 2024 19:24:43 SAST ]]> Medication adherence: a review of policy and education in South Africa Sat 24 Feb 2024 19:11:37 SAST ]]> COVID19 and accountability in South Africa: legislation, ethics and disaster risk management Sat 24 Feb 2024 19:10:47 SAST ]]> Fire disaster management in South Africa: modelling and data analysis at national and local level of government Sat 24 Feb 2024 19:09:34 SAST ]]> Quinolone-Pyrazinamide derivatives: synthesis, characterisation, in silico ADME analysis and in vitro biological evaluation against Mycobacterium tuberculosis Sat 24 Feb 2024 19:08:34 SAST ]]> Application of in vitro release testing (IVRT) to assess “sameness”/differences of topical clotrimazole formulations Sat 24 Feb 2024 19:06:16 SAST ]]> Origin and metallogenic significance of alkali metasomatism in the Paleoproterozoic Mapedi Formation, Kalahari Manganese Field, South Africa Sat 20 Apr 2024 19:54:54 SAST ]]> Controls of lateral and vertical variations in the geochemistry of the Hotazel Fe-Mn Formation at Nchwaning and Gloria mines, Kalahari Manganese Field, South Africa Sat 20 Apr 2024 19:47:24 SAST ]]> High-resolution hydraulic modelling as an approach to planning rehabilitation interventions in unchanneled valley-bottom palmiet wetlands: a case study of the Kromme River Sat 20 Apr 2024 19:32:59 SAST ]]> Remote sensing as a monitoring solution for water hyacinth (Pontederia crassipes) in the context of the biological control programme at Hartbeespoort Dam Sat 20 Apr 2024 19:26:05 SAST ]]> Relating vegetation distribution to cycles of erosion and deposition in the Kromme River wetlands Sat 20 Apr 2024 19:19:43 SAST ]]> Maintaining the façade: the disconnect between policy and practice in heritage resources management in Makhanda, South Africa Sat 20 Apr 2024 19:19:11 SAST ]]> Selected medicinal plants leaves identification: a computer vision approach Sat 20 Apr 2024 18:50:59 SAST ]]> Enhancement of the electrocatalytic activity of phthalocyanines through the reduction in symmetry and conjugation to detonation nanodiamonds Sat 20 Apr 2024 18:43:59 SAST ]]> Octa carboxy metal (II) phthalocyanine covalent films as pH sensitive electrochemical sensor for neurotransmitters Sat 20 Apr 2024 18:30:13 SAST ]]> Halogenated Aza-BODIPY dyes for photodynamic anticancer and antimicrobial activity studies 50.

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 ]]> Freshwater invasive alien crayfish species in South Africa: testing eDNA assessment and DNA barcoding Sat 20 Apr 2024 17:06:17 SAST ]]> Enteric microbial responses to host hyperthermia in southern African insectivorous bats: a test of thermal co-adaptation Sat 20 Apr 2024 16:45:11 SAST ]]> Phylogeography of two small owl species in South Africa: population genetics and phenotypic variation in the African Barred Owlet (Glaucidium capense) and the African Scops Owl (Otus senegalensis) Sat 20 Apr 2024 16:31:32 SAST ]]> Comparison of the metabolic physiology of exploited and unexploited populations of red roman (Chrysoblephus laticeps) along the south coast of South Africa Sat 20 Apr 2024 16:17:00 SAST ]]> An investigation into fatigue prevalence amongst citrus packhouse sorters in the Eastern Cape province of South Africa Sat 20 Apr 2024 13:15:15 SAST ]]> Characterizing shift systems and exploring their effects on sleep and fatigue in South African freight railway operators Sat 20 Apr 2024 13:14:24 SAST ]]> Quantifying the training demands of an amateur women’s Rugby union team using Global Positioning System Sat 20 Apr 2024 13:01:02 SAST ]]> Quantifying the work demands of municipal waste workers to determine physical workload and perception Sat 20 Apr 2024 12:40:40 SAST ]]> A study on visual inspection of citrus sorters in a packhouse in the Eastern Cape of South Africa Sat 20 Apr 2024 12:33:12 SAST ]]> Applying human factors and ergonomics system analysis methods to the V5-NRS Cessna 441 Conquest II aviation accident Sat 20 Apr 2024 12:25:51 SAST ]]> Development of an evidence-based framework for the prevention and management of musculoskeletal disorders in South Africa Sat 20 Apr 2024 12:19:21 SAST ]]> Associations between contraceptive use, physical activity, depression, and quality of life among women of childbearing age in Akure South Local Government area of Ondo State, Nigeria Sat 20 Apr 2024 12:12:41 SAST ]]> Analysing equity and ethical dimensions of water governance challenges in the lower section of the upper Vaal River catchment, Gauteng, South Africa Sat 20 Apr 2024 11:51:34 SAST ]]> Assessment of Pitman Model Capabilities in Modelling Surface Water-Groundwater Interactions in the Lake Sibaya Catchment, South Africa Sat 20 Apr 2024 11:44:29 SAST ]]> Investigation into methods of recovering campylobacter spp. from river water samples Sat 20 Apr 2024 11:37:08 SAST ]]> Evaluating the potential effects of microplastics at environmentally realistic concentrations in South African freshwater systems Sat 20 Apr 2024 11:30:12 SAST ]]> Macroplastics in the environment: are they suitable habitats for macroinvertebrates in riverine systems? 10 – 20 mm) and large (20 > 40) body size, flat body, collector-gatherers, free-living, and predators. The late colonisers, collected mainly on day 150 and 180 were dominated by taxa with a preference for high flow velocity (0.3 - 0.6 m/s), permanent attachment, and filter-feeding mode. Traits such as oval and flat body shape, medium body size (>10 - 20 mm), skating and clinging/climbing mobility, temporal attachment, shredders, predators, prey, and plastron and spiracle respiration showed positive correlation with the 100% macroplastic substrates. Filter feeding, crawling, permanent attachment, a preference for fast velocity (0.3-0.6 m/s), and coarse particle organic matter were positively correlated with the 50% macroplastic substrates. Overall, the results provided critical insights on the impact of macroplastics on the assemblage structure of biological communities by acting as suitable habitats in stream ecosystems. The study elucidated the role of traits of aquatic organisms in mediating the colonisation of plastics substrates, providing insights into the impact of plastics proliferation on riverine ecosystem functioning. Furthermore, the finding provides a baseline insight into the influence of hydraulic biotopes on the colonisation and establishment of macroinvertebrates on macroplastic acting as artificial riverine habitat.]]> Sat 20 Apr 2024 11:29:54 SAST ]]> Examining teachers’ pedagogical strategies for fostering critical thinking skills in English as a Second Language (ESL) classrooms: a case study of selected Namibian secondary school teachers Sat 20 Apr 2024 10:40:47 SAST ]]> Exploring the strategies for teaching reading comprehension to non-readers in upper primary phase: a case study of Namibian Grade 5 ESL experienced teachers Sat 20 Apr 2024 10:27:01 SAST ]]> An exploration into how Grade 3 Foundation Phase teachers implement differentiated instructional practices in their mathematics classrooms Sat 20 Apr 2024 09:58:35 SAST ]]> Investigating pedagogical practices of English First Additional Language educators in Grade 12 short stories: a case study Sat 20 Apr 2024 09:52:04 SAST ]]> Exploring grade 8 teachers’ code-switching in teaching orthographic drawing in the Khomas Educational Region, Namibia Sat 20 Apr 2024 09:44:44 SAST ]]> Exploring how Grade 11 Chemistry teachers mediate learning of the topic redox reactions in their classrooms in Namibia Sat 20 Apr 2024 09:37:59 SAST ]]> Developing a socio-economic framework for assessing the effectiveness of Expanded Public Works Programmes (EPWP): The case of the Prosopis mesquite Working for Water clearing project in the Northern Cape Province, South Africa Sat 17 Feb 2024 11:56:05 SAST ]]> Morphology, histology and histochemistry of the digestive tract of the Banded tilapia, Tilapia sparrmanii (Perciformes: Cichlidae) Mon 22 Feb 2021 13:14:37 SAST ]]> A distributed approach to leadership in an academic department in a South African university: an exploratory case study Mon 22 Apr 2024 19:39:31 SAST ]]> Investigating teachers’ perceptions on translanguaging pedagogy in a multilingual intermediate ESL classroom: a comparative study of two primary schools in Namibia Mon 22 Apr 2024 19:39:23 SAST ]]> Technological Pedagogical Content Knowledge (TPACK): investigating senior primary mathematics teachers’ integration of technology in the classroom in Okahao educational circuit Fri 19 Apr 2024 08:14:01 SAST ]]> Assessing rural senior primary school natural science teachers’ TPACK: a case study Fri 19 Apr 2024 08:00:09 SAST ]]> Exploring senior phase teachers’ use of kahoot!
