intermediate 18:1n-9/18:1n-7 ratios at ~1.3, less enriched δ¹⁵N values at ~7.9 ‰; zooplankton contribution of 10-15 % of the diet). The more depleted nitrogen signatures in the mussels relative to the barnacles and polychaetes possibly illustrated a stronger preference for autotrophic food. Polychaetes mainly consumed plant food sources (i.e. microalgae, macroalgae and detritus; high levels of i-18:0, 18:1n-9, 18:4n-3 and 20:5n-3) and displayed little omnivory (low levels of 20:1n-11 and 20:1n-9, low 18:1n-9/18:1n-7 ratios at ~0.4, intermediate δ¹⁵N values at ~9.1 ‰; zooplankton contribution of <10 % of the diet). The barnacles, mussels and polychaetes are all suspension-feeders, originally presumed to consume the same food sources. The variations observed among the species, therefore, may result from differences in the proportional contributions of the various food sources to their diets as well as distinctions in metabolism. The distinct changes in the fatty acid and stable isotope signatures in all three filter-feeders in the Kariega and Great Fish regions are likely influenced by the diversity in regional vegetation and hydrology in the different systems, combined with interspecific differences in resource partitioning among the species.]]> Thu 13 May 2021 04:32:19 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:2504 Thu 13 May 2021 04:31:01 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:6029 Thu 13 May 2021 04:30:44 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1181 Thu 13 May 2021 04:29:25 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5373 Thu 13 May 2021 04:28:03 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:4748 Thu 13 May 2021 04:27:01 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5124 0.05) differences for muscle activity between conditions, except for the semitendinosus muscle, which was significantly (p< 0.05) higher during the control condition while running at high speeds. Players‘ heart rates, core temperatures and perceptual responses were significantly (p< 0.05) higher during the experimental condition, compared to the control condition. Performance responses were significantly (p< 0.05) lower during the experimental condition. Conclusion: The main driver of physiological and perceptual responses was the exercise itself. However, the additional clothing and protective gear exacerbated the responses, particularly towards the end stages of the protocol. This negatively impacted players‘ performance. Muscle activity appeared to be unaffected by increased body temperatures. However, core temperatures never reached critically high levels during either condition.]]> Thu 13 May 2021 04:19:45 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1508 Thu 13 May 2021 04:17:36 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1669 Thu 13 May 2021 04:15:38 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:585 Thu 13 May 2021 04:06:44 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5374 600 km) between aggregation and spawning areas. This uncertainty in the level of connectivity among coastal regions was addressed using mitochondrial DNA sequencing and genotyping of microsatellite repeat loci in the nuclear genome, which showed no evidence of major geographic barriers to gene flow in this species. Samples collected throughout the white steenbras core distribution showed high genetic diversity, low genetic differentiation and no evidence of isolation by distance or localised spawning. Although historically dominant in several fisheries, analysis of long-term commercial and recreational catch data for white steenbras indicated considerable declines and ultimately stock collapse. Improved catch-per-unit-effort in two large MPAs subsequent to closure confirmed that MPAs can be effective for the protection of white steenbras. However, the current MPA network encompasses a low proportion of sandy shoreline, for which white steenbras exhibits an affinity. Many MPAs do not prohibit recreational shore angling, which currently accounts for the greatest proportion of the total annual catch. Furthermore, EPAs within the juvenile distribution protect a negligible proportion of the total available surface area of estuaries – habitat on which white steenbras is wholly dependent. Despite some evidence of recent increases in abundance in estuaries and the surf zone in certain areas, white steenbras meets the criteria for “Endangered” on the IUCN Red List of Threatened Species, and for “Protected species” status on the National Environmental Management: Biodiversity Act of South Africa. The species requires improved management, with consideration for its life-history style, estuarine dependency, surf zone residency, predictable spawning migrations and its poor conservation status. The multidisciplinary approach provides valuable information towards an improved scientific basis for the management of white steenbras and a framework for research that can be adopted for other overexploited, estuarine-associated coastal fishery species.]]> Thu 13 May 2021 04:06:38 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1420 Thu 13 May 2021 04:06:14 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:4314 Thu 13 May 2021 04:04:18 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1013 Thu 13 May 2021 03:58:59 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5636 Thu 13 May 2021 03:50:03 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:4313 Thu 13 May 2021 03:38:11 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:3870 Thu 13 May 2021 03:35:30 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:814 Thu 13 May 2021 03:30:21 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1005 Thu 13 May 2021 03:16:13 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:3675 Thu 13 May 2021 03:14:07 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1003 Thu 13 May 2021 03:12:00 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:3681 Thu 13 May 2021 03:08:45 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:3871 Thu 13 May 2021 03:06:22 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5724 Thu 13 May 2021 03:05:16 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5778 Thu 13 May 2021 03:03:20 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:2983 Thu 13 May 2021 02:58:57 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:4400 Thu 13 May 2021 02:57:41 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5141 Thu 13 May 2021 02:50:03 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1004 Thu 13 May 2021 02:46:55 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:3317 Thu 13 May 2021 02:44:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1912 Thu 13 May 2021 02:43:46 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:3143 Thu 13 May 2021 02:41:29 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:1633 Thu 13 May 2021 02:27:53 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5297 Thu 13 May 2021 02:27:38 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:776 Thu 13 May 2021 02:19:20 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:4005 Thu 13 May 2021 02:15:53 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5308 Thu 13 May 2021 02:15:19 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:2758 Thu 01 Feb 2024 09:47:31 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:4606 Mon 06 May 2024 05:23:01 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:573 Fri 27 Aug 2021 09:43:47 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:588 Fri 26 Apr 2024 11:24:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:25947 Fri 10 May 2024 03:31:06 SAST ]]>
