Chiov., a threatened medicinal plant in southern Mozambique https://vital.seals.ac.za/vital/access/manager/Repository/vital:50042 20 cm) size classes in all the study areas but gatherers avoided harvesting bark from recruits. Although the mean densities of harvested stem was not significant this work indicated higher levels of stem destruction in FC. Harvested dead stems ware significant in the three areas and FC had the higher of (39.5±85.9 stems/ha) compared to 7.6±19.1 and 2.1±4.3 in TR and LM, respectively. Equally, the density of physiologically stressed stems differed substantially in the three areas with higher in FC 20.5± 75.5 stems/ha compared to 18.7±82.9 stems/ha in TR and 3.8±11.8 stems/ha in LM. This results suggests implementation of protection measures such as the inclusion of the species in the national CITES list to regulated cross-border trade and strengthening of the law enforcement. Genetic diversity, structure and gene flow in the exiting populations of southern Mozambique revealed that despite fragmentation and overexploitation, this species maintains a relatively high level of genetic diversity supporting the existence of random mating. Two genetic groups were found corresponding to the northern (LM and TR) and southern (FC) areas. The study suggests that, if local extinctions occurred in Mozambique, the pepper-bark tree persisted in sufficient numbers to retain a large proportion of genetic diversity. Management plans should concentrate on maintaining this high level of genetic variability through both in and ex-situ conservation actions.]]> Thu 01 Sep 2022 11:56:53 SAST ]]> Effect of adding a probiotic to an aquaponic system on plant and fish growth, water quality, and microbial diversity https://vital.seals.ac.za/vital/access/manager/Repository/vital:57236 Sun 09 Oct 2022 18:49:45 SAST ]]> Environmental governance, agency and multi-actor dynamics in Southern Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:49984 Sun 09 Oct 2022 18:08:57 SAST ]]> Structural determinants of the HSP90-Fibronectin interaction and implications for fibrillogenesis https://vital.seals.ac.za/vital/access/manager/Repository/vital:57234 Sun 09 Oct 2022 18:07:39 SAST ]]> The transformative potential of intersecting arts-based inquiry and environmental learning in urban South Africa: a focus on socio-ecological water pedagogies https://vital.seals.ac.za/vital/access/manager/Repository/vital:56772 Sat 17 Feb 2024 12:25:24 SAST ]]> Quantifying the impacts of cactus biological control agents in South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:57239 Mon 24 Oct 2022 16:23:01 SAST ]]> Singlet oxygen and optical limiting applications of BODIPYs and other molecular dyes https://vital.seals.ac.za/vital/access/manager/Repository/vital:57238 Mon 24 Oct 2022 15:47:54 SAST ]]> Dynamics of charge movement in ∞-Al2O3:C,Mg using thermoluminescence phototransferred and optically stimulated luminescence https://vital.seals.ac.za/vital/access/manager/Repository/vital:57237 Mon 24 Oct 2022 14:52:01 SAST ]]> The role of angling-guides in promoting pro-environmental catch-and-release attitudes and behaviours in the recreational angling community https://vital.seals.ac.za/vital/access/manager/Repository/vital:57235 Mon 24 Oct 2022 09:15:55 SAST ]]> Sequence, structure, dynamics, and substrate specificity analyses of bacterial Glycoside Hydrolase 1 enzymes from several activities https://vital.seals.ac.za/vital/access/manager/Repository/vital:50129 Mon 10 Oct 2022 08:54:24 SAST ]]> Neutral winds and tides over South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:49993 Mon 10 Oct 2022 08:47:40 SAST ]]> The systematic assembly of prostate specific antigen electrochemical sensors based on asymmetric Co(II) phthalocyanines, graphitic quantum dots and an aptamer https://vital.seals.ac.za/vital/access/manager/Repository/vital:50035 Mon 10 Oct 2022 08:41:01 SAST ]]> Demersal fish distribution in the shallow marine nearshore and estuarine seascape of Algoa Bay: Nursery areas and the effect of environmental drivers https://vital.seals.ac.za/vital/access/manager/Repository/vital:49988 20 μg Chl-a l-1) that result in instances of bottom water oxygen depletion (< 4 mg/l). During the present study in the Sundays Estuary, low oxygen waters were recorded in the middle reaches (Site S5) mostly during summer (four months of low DO conditions). In the Swartkops Estuary, low dissolved oxygen was recorded in the upper reaches during spring. The lowest dissolved oxygen concentration recorded was 0.5 mg/l and 2.4 mg/l in the bottom waters of the Sundays and Swartkops estuaries, respectively. Selected dominant species were only absent from areas where dissolved oxygen was < 1 mg/l and present in the adjacent sites (for example Site S4, and S3) where DO was higher mostly during January 2019. As such, the low dissolved oxygen concentrations recorded in the Swartkops Estuary did not have a noticeable impact on fish distribution, although the total abundance of species did show a slight decline when dissolved oxygen was < 3 mg/l. This study demonstrates the importance of concurrently examining estuarine and nearshore marine habitats in order to identify ecologically important habitats, which has important implications for the development of effective management strategies for coastal fish populations, particularly in the light of anthropogenic change. In addition, in order to identify nursery hotspots it is crucial to correctly identify all the species occupying these areas. As such, this study confirms the importance of also using DNA barcoding for fish identification, particularly for the early life history stages of cryptic species (e.g. Argyrosomus inodorus and Argyrosomus japonicus).]]> Mon 10 Oct 2022 08:22:49 SAST ]]> An eco-physiological investigation of fisheries-induced evolution: comparing the resilience of larvae from exploited and unexploited commercial reef fish populations to projected ocean acidification https://vital.seals.ac.za/vital/access/manager/Repository/vital:50004 Mon 10 Oct 2022 08:02:20 SAST ]]> English additional language student teachers’ development of oral strategic competence and confidence https://vital.seals.ac.za/vital/access/manager/Repository/vital:53643 Mon 01 Aug 2022 15:47:38 SAST ]]> Exploring learners’ engagement with literacy in a book club https://vital.seals.ac.za/vital/access/manager/Repository/vital:53642 Fri 29 Jul 2022 11:48:00 SAST ]]> Synthesis and evaluation of the medicinal potential of novel 4-hydroxycoumarin derivatives https://vital.seals.ac.za/vital/access/manager/Repository/vital:41120 Fri 29 Jul 2022 08:40:40 SAST ]]> Visualisation processes in teaching patterns and their generalisation: perceptions and experiences from senior phase mathematics teachers https://vital.seals.ac.za/vital/access/manager/Repository/vital:50039 Fri 15 Jul 2022 15:41:10 SAST ]]> Chinese character learning with the aid of an ICT website among Mandarin Second Additional Language learners in South Africa: a case study https://vital.seals.ac.za/vital/access/manager/Repository/vital:53641 Fri 14 Oct 2022 15:47:43 SAST ]]> Towards the Common Good: An expansive post-abyssal (Re)stor(y)ing of the epistemic cultures of the citizen sciences https://vital.seals.ac.za/vital/access/manager/Repository/vital:56773 Fri 11 Nov 2022 13:00:08 SAST ]]>
