Further behavioural diversity was observed with ‘resident’, ‘roaming’ and ‘embayment’ contingents identified based on varying levels of affinity to certain habitats. The presence of both resident and migratory individuals within the northernmost study during June and July, combined with available biological information, suggested that area-specific spawning may take place. While PAT, CPUE and CT largely aligned in determining area specific high-area use, results from network analyses and mixed effects models conducted on the PAT data supported the spawning hypothesis, with anomalous behaviour around specific receivers during the spawning season. All fish, regardless of behavioural contingent, displayed similar movement behaviour during the spawning season and this was driven by factors generally associated with reproduction, such as lunar illumination. Interestingly, these drivers were different from those that determined the area specific use of individuals outside of the spawning season. The environmental drivers of longshore migration into the northern study site were identified as a decline in water temperature and shorter day lengths. The results of this study highlight the importance of using a multi-method approach in determining migratory movement behaviour, area specific area use, and stock structure of key fisheries species. The identification of different behavioural contingents highlights the importance of acknowledging individual variation in movement and habitat-use patterns. This is particularly relevant as future climate change and spatiotemporal variation in fishing effort may artificially skew natural selection processes to favour certain behavioural groups. This study also highlighted the importance of scientists forming relationships with resource-users, such as recreational angling lodges in areas where limited research has been conducted. This is particularly relevant within the West African context where little is known about many of the fish species that are being increasingly targeted by tourism angling ventures.]]> Thu 29 Sep 2022 14:25:47 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31213 Thu 29 Sep 2022 14:24:30 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30599 Thu 29 Sep 2022 14:23:25 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29924 0.05), development or the active metabolic (P > 0.05) or metabolic scope (P > 0.05) of fish in the three treatments throughout the study. However, the standard metabolic rate was significantly higher in the year 2068 treatment but only at the flexion/post-flexion stage which could be attributed to differences in developmental rates (including the development of the gills) between the 2068 and the other two treatments. Overall, the metabolic scope was narrowest in the 2090 treatment, but varied according to life stage. Although not significantly different, metabolic scope in the 2090 treatment was noticeably lower at the flexion stage compared to the other two treatments, and the development appeared slower, suggesting that this could be the stage most prone to OA. The study concluded that, in isolation, OA levels predicted to occur between 2050 and 2090 will not negatively affect size-at-hatch, growth, development, and metabolic responses of larval A. japonicus up to 22 DAH (flexion/post-flexion stage). Taken together with the previous studies of the same species, the tipping point of tolerance (where negative impacts will begin) in larvae of the species appears to be between the years 2090 and 2100.]]> Thu 29 Sep 2022 12:56:05 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31252 Thu 20 Jul 2023 11:52:05 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29119 Thu 13 May 2021 16:04:33 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:34053 Thu 13 May 2021 15:31:44 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30711 Thu 13 May 2021 15:04:39 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31404 Thu 13 May 2021 12:43:26 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29914 Thu 13 May 2021 11:49:39 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30709 150% intensity) were old gravity schemes. Farmers on approximately 75% of Limpopo smallholder schemes are currently engaging in land exchange transactions in a highly insecure and un-formalised institutional setup. Land exchange prevalence longer than two years was moderately associated with cropping intensity and strongly associated with commercialisation. This result has three important implications. First, it suggests that more land is utilised on the schemes when there is vibrant land-leasing activity. Secondly, schemes with a higher prevalence of long-term leasing seem to have a strong tendency to be more commercialised. Thirdly, the duration of the lease is significant, as neither single-season, nor annual leases yielded any positive associations, while those exchanges that were two years or longer, were associated with increased performance. These findings highlight the potential for longer-term land-exchange interventions to address the widespread low land utilisation on smallholder schemes, and to catalyse more commercially-oriented farming. An irrigation scheme typology was derived from the cluster analysis and was aligned to a contemporary irrigation farming typology. The key descriptors included technology type, purpose of farming and scheme management type. By matching scheme type to the farmer typology (or typologies), strategic decisions regarding technology choices for infrastructure, land, and water institutional interventions can be better informed. All schemes demand attention to the multiple factors required to achieve performance, not least water-tenure security, irrigation management organisational development, and infrastructure modernisation. Complexity was demonstrated by the finding that multiple factors contribute to success, and that there are many dimensions that change independently and have a cascading effect through the system in ways that are difficult to predict. Agricultural systems support to achieve productivity and profitability are essential for success. The research findings lead to the recommendation that, in addition, strategic planners must also consider the implications of the dominant factors of water-technology choices so that these are manageable, and the dynamics of farm-size change based on land exchange processes, in order to harness new opportunities to maximise irrigation scheme performance in future.]]> Thu 13 May 2021 11:26:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:34076 Thu 13 May 2021 11:24:47 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:34055 Thu 13 May 2021 10:24:28 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31194 Thu 13 May 2021 08:55:46 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31075 Thu 13 May 2021 08:45:50 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30738 Thu 13 May 2021 08:18:40 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29132 Thu 13 May 2021 08:18:14 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:34082 Thu 13 May 2021 08:14:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30589 50Îll viability at concentrations≤ 160μg/mL, however the conjugates showed<50% cell viabilityatconcentrations≤ 160μg/mLprobably due to the enhanced singlet oxygen quantum yield.

Masoke Iron Formation (Kanye Basin) which is stratigraphic correlative of The Ghaap Group and Chuniespoort Group of the Griqualand West basin and Transvaal basin, respectively. The Palaeoproterozoic Transvaal Supergroup in the Northern Cape Province of South Africa hosts high grade (>60% Fe) hematitic and specularitic iron and manganese mineralisation. It is therefore important to study and record the petrographic, mineralogy and geochemistry of Masoke Iron Formation, compare the results to the much known Kuruman and Griquatown Iron Formations. This study systematically investigate and record the petrography, mineralogy and geochemistry of all Masoke Iron Formation of Taupone Group in the Kanye Basin, which is stratigraphic correlative of The Ghaap Group and Chuniespoort Group of the Griqualand West basin and Transvaal basin, respectively. The further objective is to compare Masoke Iron Formation to the equivalent units in the Transvaal basin and Griqualand basin. In contrast to both Transvaal and Griqualand West Basin the Masoke iron Formation (Kanye Basin) has not been the subject of systematic scientific investigations. The study covers three main areas in the Kanye Basin: Keng Pan Area, Ukwi/Moretlwa hill and Janeng Hill Area. The mineralogy and geochemistry of these areas are presented in this study. Kanye Basin has a potential to host a large iron ore deposit, the geological setting in this area incorporates many of the elements necessary for iron ore formation. These include: banded iron formation (BIF), major unconformities with prolonged periods of weathering, carbonate sequences etc. In addition, several large deposits and mines are known from this area. This area can potentially have both hypogene and supergene enrichment of BIF. In this model, prospectively for new deposits is a function of the following: presence of iron formation units, proximity of mapped Asbestos Hills and Voëlwater BIF, thrust faulting (as indicated by the aero-magnetic interpretation), duplication of the ore horizon by folding, intersection of the BIF by major extensional fault, proximity of Olifantshoek/Waterberg outcrop, Gamagara unconformity, presence of carbonates (dolomites) and thin Kalahari sand cover. Major BIF units in the area of study include: the Masoke Iron Formation, equivalent to Kuruman Formation of the Asbestos Hills Subgroup, the Rooinekke iron formation of the Koegas Subgroup and the Hotazel Formation of the Voëlwater Subgroup. Supergene enrichment of these BIFs may occur wherever they are overlain by a major regional unconformity. The base of the Waterberg and the OlifantshoekSupergroups represent major unconformities in this regional target area. Potential for hypogene deposits is indicated by faulting (preferably extensional) proximal to BIF.]]> Thu 13 May 2021 07:06:47 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29855 Thu 13 May 2021 07:04:59 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:28644 Thu 13 May 2021 06:58:27 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:34478 Thu 13 May 2021 06:50:15 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31220 Thu 13 May 2021 06:48:55 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30999 Thu 13 May 2021 06:47:16 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:39140 Thu 13 May 2021 06:43:16 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30967 Thu 13 May 2021 06:38:52 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:34081 Thu 13 May 2021 06:38:10 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31015 Thu 13 May 2021 06:33:52 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29125 Thu 13 May 2021 06:30:11 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29539 Thu 13 May 2021 06:24:12 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31287 Thu 13 May 2021 06:21:04 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29788 Thu 13 May 2021 06:19:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30765 Thu 13 May 2021 06:11:40 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30741 Thu 13 May 2021 06:11:29 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30547 Thu 13 May 2021 06:10:44 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30558 Thu 13 May 2021 06:10:31 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31148 Thu 13 May 2021 06:10:06 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30743 Thu 13 May 2021 06:08:53 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29237 Thu 13 May 2021 06:03:59 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:31306 Thu 13 May 2021 06:00:54 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29861 Thu 13 May 2021 06:00:40 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29223 Thu 13 May 2021 05:43:58 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:29218 0.3 h Mpc -¹ We also analyzed data from the last observing season of PAPER via all-sky imaging with a view to characterize the foregrounds.
