However, during the summer holiday period (mid-December to mid-January) few seahorses were observed on camera, which suggests that the increase in motor boat activity and the related increase in noise had a negative effect on H. capensis feeding and courting behaviour. The marina development, and in particular the Reno mattresses, created a new habitat for this endangered species within the Knysna estuary. In addition to the protection and restoration of natural habitats in which H. capensis is found, the conservation potential of artificial structures such as Reno mattresses should be realised.]]> Thu 21 Sep 2017 22:13:31 SAST ]]> Occurrence of mugilid and sparid fishes in Zostera capensis and bare sediment habitats of the Knysna Estuary Thu 21 Sep 2017 21:42:04 SAST ]]> A psychobiographical study of Temple Grandin Thu 21 Sep 2017 21:25:18 SAST ]]> Modelling plant water use of the grassland and thicket biomes in the eastern cape, South Africa: towards an improved understanding of the impact of invasive alien plants on soil chemistry, biomass production and evapotranspiration Thu 21 Sep 2017 21:24:03 SAST ]]> Dangerous liaisons or critical alliances: student perceptions of community engagement at Rhodes University, South Africa Thu 21 Sep 2017 21:22:18 SAST ]]> Essence of home: relevance of home and the assertion of place amongst Centane migrants, South Africa Thu 21 Sep 2017 20:58:37 SAST ]]> Demographic change in the Upper Tsitsa Catchment: the integration of census and land cover data for 2001 and 2011 Thu 21 Sep 2017 20:57:22 SAST ]]> Decentralization and quality assurance in the Ugandan primary education sector Thu 21 Sep 2017 20:41:48 SAST ]]> Advanced radio interferometric simulation and data reduction techniques Thu 21 Sep 2017 20:36:52 SAST ]]> Aquatic habitat shift assessment in a groundwater-fed semi-arid stream:an investigation into the response of Karoo hydroecology to system variability Thu 15 Mar 2018 16:05:22 SAST ]]> Practical application of distributed ledger technology in support of digital evidence integrity verification processes Thu 15 Mar 2018 15:37:22 SAST ]]> A survey of organizational culture and organizational performance in a manufacturing company Thu 15 Mar 2018 15:16:22 SAST ]]> A thematic analysis of the challenges experienced by those living with tuberculosis Thu 15 Mar 2018 13:17:22 SAST ]]> Biotic and abiotic drivers of macroinvertebrate assemblages in a South African river Thu 15 Mar 2018 12:35:21 SAST ]]> An investigation into the bacterial biosynthetic origins of bioactive natural products isolated from South African latrunculid sponges Thu 15 Mar 2018 12:07:24 SAST ]]> Interaction of catechol O- methyltransferase with gold and silver nanoparticles Thu 15 Mar 2018 11:32:23 SAST ]]> Performance evaluation and cost analysis of subsurface flow constructed wetlands designed for ammonium-nitrogen removal Thu 15 Mar 2018 10:57:22 SAST ]]> Baculovirus synergism: investigating mixed alphabaculovirus and betabaculovirus infections in the false codling moth, thaumatotibia leucotreta, for improved pest control Thu 15 Mar 2018 10:43:37 SAST ]]> Perceptions of Ulwaluko in a Liberal Democratic State: is multiculturalism beneficial to AmaXhosa women in the Eastern Cape province of South Africa?

Further, although not significant, the large within-group effect size (d=-0.84) between baseline and week 8 for PEx systolic blood pressure, suggested the 9 mm Hg was meaningful. The same time period also indicated a large within-group effect size (d=-0.8) for PEx dynamic balance, and a medium Cohen’s d for (d=0.57) PEx static balance. Conclusion: The local population of young adult females was found to be significantly healthier than those of comparable national samples. Further, Pilates participation significantly improved lumbo-pelvic stability and muscular endurance with meaningful changes in systolic blood pressure, and balance in previously sedentary young, adult females.

Species, life-stage (juvenile/adult) and time- at-liberty were included as predictor variables. Model coefficients were then included in a cluster analysis, which produced two primary groupings of species (Category I and II), with two sub-groupings (Category IIa and IIb). Category I species were characterised by wide-ranging movements, greatest median recapture length and highest trophic levels. Category II species were characterised by residency, lower median recapture length and lower trophic levels. These findings have implications for fisheries management. Exploitation of resident species may lead to localised depletion, but their diffuse spatial distribution may offer some resilience. In contrast, even localised targeting of migratory species may pose a population level risk if individuals are known to aggregate. Life-cycle diversity or intra-population variability describes the existence of alternative strategies or tactics among coexisting individuals within an animal population (Chapter 5). Partial migration is a specific case of life-cycle diversity where coexisting groups exhibit either resident or migratory (wide-ranging) behaviour within a single population. Mark- recapture data collected under the auspices of the ORICFTP were used to investigate the occurrence and nature of life-cycle diversity in the movement behaviour of five non- diadromous fish species around the coastline of southern Africa. Among the five species were three teleosts (Category I and IIa) and two elasmobranchs (Category I). A fish was considered to have remained resident if recaptured within 0-5 km after 365 days at liberty. A fish was considered to have undertaken a wide-ranging movement if recaptured more than 50 km away from the release site in 365 days or less. A total of 1848 individuals from the five study species were recaptured during the study, of which 73% of the observations were classified as being resident. Binomial logistic regression confirmed that species, life-stage (juvenile/adult) and ecoregion were significant (p < 0.001) predictors of the probability of wide-ranging behaviour. A Gaussian model confirmed that species and ecoregion were also significant (p < 0.001) predictors of direction and distance of wide-ranging movement. However, the direction and distance of wide-ranging movements in juveniles did not differ significantly (p > 0.05) to that of adults. The median growth rate was mostly greater in wide- ranging individuals; however, this was only statistically significant (p < 0.05) in two cases. These findings provide unequivocal evidence of life-cycle diversity in five fish species, with vastly different life-histories. This ecological phenomenon may provide species resilience at the population level and needs to be considered in fisheries management initiatives. The movement of fishes is a fundamental aspect to consider when designing fishery management regimes. Unfortunately, traditional management strategies have often disregarded movement behaviour to the detriment of fish populations (Chapter 6). As a case study, the management of Lichia amia (Category I: wide-ranging) was evaluated in the context of its movement behaviour. Long-term catch-per-unit-effort (CPUE) datasets were examined for three South African recreational fishery sectors. The CPUE was standardised using generalized linear models (delta-Gamma/hurdle approach) to reduce the effect of factors other than abundance. Factors that were available for this purpose were year, month and locality/zone. Year was included in every model as the primary objective was to detect trends in abundance over time. Although standardised CPUE for all sectors showed an overall long-term decline, there was considerable variability in trends between the different recreational sectors and between datasets. Contrasting trends between competitive shore angling and general shore angling datasets were ascribed to hyperstability in competitive CPUE data. Hyperstability in this case was mostly influenced by rapidly improving technology, techniques and communication networks amongst competitive anglers. Month and locality were significant factors explaining the probability of catching L. amia. This suggests that the predictable aggregatory behaviour of this species could further compound the observed CPUE hyperstability. Although the CPUE responded positively for six years after implementation of the first minimum size and bag limits, and for one year after the decommercialisation of the species, these regulations and their amendments failed to arrest a long-term decline in the CPUE despite the ample evidence for hyperstability. It is clear from this case study that the predictable nature of wide-ranging behaviour in L. amia has made the population vulnerable to exploitation. This has led to the demise in the population, which could have been worse if not for the occurrence of intra-population variability in its movement behaviour, which may provide some measure of resilience.]]> Fri 16 Feb 2018 16:11:56 SAST ]]> The ecological risk of acid mine drainage in a salinising landscape Fri 16 Feb 2018 15:46:04 SAST ]]> Sulphur isotope study of pyrite from the Twangiza-Namoya Gold Belt, (South Kivu, DRC): a proxy of gold provenance Fri 16 Feb 2018 13:53:31 SAST ]]> Discontinuous gully erosion as a mechanism of wetland formation: a case study of the Kompanjiesdrif basin, Kromrivier, Eastern Cape, South Africa Fri 16 Feb 2018 13:04:59 SAST ]]> The changing face of Rhodes University: exploring aspects of visuality, sexuality and protest between the apartheid and postapartheid periods Fri 16 Feb 2018 12:15:59 SAST ]]> Featuring simplicity: jargon and access in contemporary South African art Fri 16 Feb 2018 11:33:59 SAST ]]> A counter-narrative analysis of psychological riot in contemporary painting Fri 16 Feb 2018 11:26:59 SAST ]]> A baseline survey of channel geomorphology with particular reference to the effects of sediment characteristics on ecosystem health in the Tsitsa River, Eastern Cape, South Africa Fri 13 Oct 2017 16:58:02 SAST ]]> Characterisation of surfaces modified with phthalocyanines through click chemistry for applications in electrochemical sensing Fri 13 Oct 2017 15:22:39 SAST ]]> Challenging Biblical boundaries: Jeanette Winterson’s postmodern feminist subversion of Biblical discourse in Oranges are not the only fruit (1985) and Boating for beginners (1985) Fri 12 Jan 2018 15:20:31 SAST ]]> An exploration of whether using a global employment company could mitigate the South African tax risks in relation to inbound expatriates in multinational companies Fri 09 Mar 2018 14:29:21 SAST ]]> Performing the township: pantsula for life Fri 06 Oct 2017 15:10:31 SAST ]]> Preimages for SHA-1 Fri 06 Oct 2017 12:53:02 SAST ]]> Developmental and reproductive performance of a specialist herbivore depend on seasonality of, and light conditions experienced by, the host plant Fri 02 Mar 2018 11:58:49 SAST ]]>
