At a constant temperature (20°C), the oxygen consumption rate of M. wooldridgei decreased with an increase in salinity. Salinity tolerance of the mysid was strongly modified by temperature. At 5‰ and 30°C, mysids exhibited mass mortality. The Q10 value for M. wooldridgei at 15, 25 and 35‰ was estimated at 2.34, 1.44 and 2.14, respectively. Results of the study suggest that M. wooldridgei is well adapted to surviving in environments characterised by variations in temperature and salinity. Within the Great Fish Estuary, total chl. a concentration ranged between 2.68 μg L-1 and 31.12 μg L-1 and was always dominated by large phytoplankton cells (>5 μm). Average zooplankton abundance ranged between 62 and 28 917 ind. m-3 and biomass between 10 and 203 mg Dwt m-3. The zooplankton community was numerically dominated by the calanoid copepod Pseudodiaptomus hessei, which comprised up to 100% (range between 12 and 100%) of the total zooplankton counted. Total zooplankton biomass during the day was dominated by copepods and by mysids during the nighttime. Among the mysids, M. wooldridgei was the most numerically abundant mysid and comprised <10% of the total zooplankton abundance. Numerical analysis found no seasonal pattern in the total zooplankton abundance (including mysids). The lack of any seasonality could be attributed to the continuous freshwater inflow into the estuary due to the inter-basin transfer of water from the Gariep Dam to the Fish River system. A distinct spatial pattern in the zooplankton community structure was evident with the upper stations almost entirely dominated by the copepod P. hessei, while at stations occupied in the lower reaches of the estuary, the zooplankton community comprised a mixture of freshwater, estuarine and marine breeding zooplankton species. The mysids also demonstrated a distinct spatial pattern in their distribution. Mysids were generally absent from the upper reaches, while in the middle reaches Rhopalophthalmus terranatalis and M. wooldridgei were numerically dominant. Gastrosaccus brevifissura dominated in the lower regions of the estuary. Stable isotope analysis (δ13C) indicated that the dominant source of carbon utilised by the numerically dominant copepods and juvenile M. wooldridgei within the estuary was derived from the extensive phytoplankton stocks within the system. In contrast, sub-adult and adult mysids (R. terranatalis, M. wooldridgei and G. brevifissura) appeared to consume a combination of phytoplankton and copepods. The contribution of the various sources of carbon to the total carbon intake of the mysid remains unknown.]]> Wed 12 May 2021 23:42:36 SAST ]]> A study of the factors influencing the success of

However, the low screen allowed for the Short subjects to adopt the most natural general body postures, although levels of muscular activity in the upper trapezius suggest that the muscular load imposed on both Short and Tall subjects was significantly greater than that imposed on the Medium subjects. In addition, the Medium subjects’ perceptions of the Standard workstation dimensions support the fact that this workstation was better suited to users with “average” morphologies. The responses elicited in the Personalised and Wrist Support workstations were improved significantly when compared to the Standard workstation. Joint angles were more natural, upper trapezius EMG was reduced, standard of performance improved and perceptual responses indicated a diminished incidence of body and visual discomfort, as well as greater perceived satisfaction with these workstation dimensions. The improved physical responses suggest a decrease in the risk of developing cumulative trauma disorders. Although subjects were unaccustomed to the wrist support device, this workstation demonstrated a further reduction in the range of wrist angles, as well as a general positive attitude towards the concept.]]> Thu 13 May 2021 05:56:42 SAST ]]> The nature and potential of industrial development within the Southern African Development Community (SADC) and the facilitating role of trade liberalisation and foreign direct investment in selected countries https://commons.ru.ac.za/vital/access/manager/Repository/vital:1071 Thu 13 May 2021 05:50:53 SAST ]]> An investigation into the antidepressant activity of hypericum perforatum https://commons.ru.ac.za/vital/access/manager/Repository/vital:3793 Thu 13 May 2021 05:42:51 SAST ]]> Rainfall variability in Southern Africa, its influences on streamflow variations and its relationships with climatic variations https://commons.ru.ac.za/vital/access/manager/Repository/vital:6030 Thu 13 May 2021 05:37:21 SAST ]]> Re-inventing educational leadership for school and community transformation: learning from the Educational Leadership Management and Development programme of the University of Fort Hare https://commons.ru.ac.za/vital/access/manager/Repository/vital:1719 Thu 13 May 2021 05:33:14 SAST ]]> Fractured solidarities: labour regulation, workplace restructuring, and employment 'flexibility' in Namibia https://commons.ru.ac.za/vital/access/manager/Repository/vital:3343 Thu 13 May 2021 05:29:53 SAST ]]> Tertiary treatment in integrated algal ponding systems https://commons.ru.ac.za/vital/access/manager/Repository/vital:4068 Thu 13 May 2021 04:58:30 SAST ]]> Institutional change and ecosystem dynamics in the communal areas around Mt Coke State Forest, Eastern Cape, South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:4746 Thu 13 May 2021 04:56:04 SAST ]]> Use of the internet in newsgathering : a case study of The Post newspaper in Zambia https://commons.ru.ac.za/vital/access/manager/Repository/vital:3518 Thu 13 May 2021 04:42:53 SAST ]]> Discourses surrounding 'race', equity, disadvantage and transformation in times of rapid social change : higher education in post-apartheid South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:3142 Thu 13 May 2021 04:39:15 SAST ]]> Formulation and assessment of verapamil sustained release tablets https://commons.ru.ac.za/vital/access/manager/Repository/vital:3869 Thu 13 May 2021 04:37:15 SAST ]]> Conceptualizing and implementing the meaning of Africa's new partnership with the industrialized north : implications and possibilities for the renaissance https://commons.ru.ac.za/vital/access/manager/Repository/vital:2841 Thu 13 May 2021 04:33:05 SAST ]]> Strategies used by subject advisors and facilitators to support lesson planning with an environmental learning focus : a case study of the Eastern Cape Neep-Get cluster https://commons.ru.ac.za/vital/access/manager/Repository/vital:1926 Thu 13 May 2021 04:28:08 SAST ]]> Euphausiid population structure and grazing in the Indian sector of the Antarctic Polar Frontal Zone, during austral autumn https://commons.ru.ac.za/vital/access/manager/Repository/vital:5913 0.05). The multivariate analysis identified two interacting mechanisms controlling the distribution patterns, abundance and biomass of the various euphausiid species, namely (1) diel changes in abundance and biomass, (2) and restricted distribution patterns associated with the different water masses. Ingestion rates were determined for five euphausiid species. E. triacantha was found to have the highest daily ingestion rate ranging from 1 226.1 to 6 029.1 ng pigm ind⁻¹d⁻¹, while the lowest daily ingestion rates were observed in the juvenile Thysanoessa species (6.4 to 943.0 ng pigm ind⁻¹ d⁻¹). The total grazing impact of the selected euphausiids ranged from < 0.1 to 20.1 μg pigm m⁻²d⁻¹, corresponding to < 0.15 % of the areal chl-a biomass. The daily ration estimates of autotrophic carbon for the euphausiids suggested that phytoplankton represented a minor component in their diets, with only the sub-adult E. vallentini consuming sufficient phytoplankton to meet their daily carbon requirements. A cyclonic cold-core eddy spawned from the region of the APF located in the southwest Indian sector of the PFZ was the dominant feature during the 2005 survey. The total areal chl-a biomass throughout the region was low, ranging between 5.6 and 11.4 mg chl-a m⁻², and was significantly higher within the core of the eddy compared to the surrounding waters (p < 0.05). RMT-8 and WP-2 total euphausiid abundance and biomass estimates were high, and ranged from 0.004 to 0.36 ind m⁻³ and 0.065 to 1.21 mg dwt m⁻³, and from 0.01 to 18.2 ind m⁻³ and 0.01 to 15.7 mg dwt m⁻³, respectively. A distinct spatial pattern in the euphausiid community was evident with the Antarctic species, Euphausia frigida, E. triacantha and E. superba predominating within the core of the eddy, while the PFZ waters were characterized by the sub-Antarctic species, E. longirostris, Stylocheiron maximum, Nematoscelis megalops and Thysanoessa gregaria. The eddy edge acted as a transition zone where species from both regions co-occurred. Within the survey area the combined ingestion rate of the six numerically dominant euphausiid species ranged between 0.02 and 5.31 μg pigm m⁻²d¹, which corresponded to a loss of between < 0.001 and 0.11 % of the available chl-a biomass. E. triacantha and juvenile T. macura were identified as the dominant grazers. There was no apparent spatial pattern in the grazing activity of the euphausiids within the region of investigation. The average daily rations of the euphausiids examined were < 2 % of their body carbon. The low daily ration of the euphausiids could be ascribed to the predominance of small picophytoplankton in the region of investigation, which are too small to be grazed efficiently by larger zooplankton. The marked spatial patterns in species composition and the elevated abundance and biomass of euphausiids, suggest that the mesoscale eddies contribute to the spatial and temporal heterogeneity of the planktonic community of the PFZ and may represent important foraging regions for many of the apex predators within the region.]]> Thu 13 May 2021 04:21:56 SAST ]]> The safety of journalists: an

The Φ[subscript]f values for the complexes under study are within the range reported for complexes currently used for PDT.]]> Thu 13 May 2021 00:21:54 SAST ]]> A comparative bioinformatic analysis of zinc binuclear cluster proteins https://commons.ru.ac.za/vital/access/manager/Repository/vital:4004 Thu 13 May 2021 00:20:34 SAST ]]> The anatomy and distribution of the cyperaceae in the Eastern Cape region of South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:4228 Thu 13 May 2021 00:20:07 SAST ]]> The biology of suburban olive thrushes (Turdus olivaceus olivaceus) in the Eastern Cape, South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:5651 Thu 13 May 2021 00:19:52 SAST ]]> An investigation of an undergraduate course module on the ethical aspects of information systems https://commons.ru.ac.za/vital/access/manager/Repository/vital:1139 Thu 13 May 2021 00:12:51 SAST ]]> Screening of technologies for the recovery of rhodium (III) metal ions from a precious metal refinery wastewater https://commons.ru.ac.za/vital/access/manager/Repository/vital:3987 Thu 13 May 2021 00:11:24 SAST ]]> The relationship between leadership and internal customer satisfaction within a motor manufacturing company in Gauteng https://commons.ru.ac.za/vital/access/manager/Repository/vital:758 Thu 13 May 2021 00:07:54 SAST ]]> The use of Van Hiele's theory to explore problems encountered in circle geometry: a grade 11 case study https://commons.ru.ac.za/vital/access/manager/Repository/vital:1871 Thu 13 May 2021 00:00:35 SAST ]]> Using aspects of game theory for enhanced stakeholder participation perspectives in integrated water resource management: a Kat River Valley case study https://commons.ru.ac.za/vital/access/manager/Repository/vital:971 Thu 06 Jul 2023 16:10:58 SAST ]]> Creating a relationship: a discourse analysis focusing on the construction of identities and relationships in distance education materials for a teacher upgrade programme https://commons.ru.ac.za/vital/access/manager/Repository/vital:1467 Thu 06 Jul 2023 12:06:41 SAST ]]>
