In addition to the tracer and FFG analyses for examining trophic connections between land and river, the bidirectional exchange of organisms between the riparian zone and the river was assessed using floating pyramidal traps (to measure emergence) and pan traps (for infalling invertebrates) placed at different sites in the river and the biomass in each trap was determined. The exchanges were variable over space and time, with emergence peaking in summer (169 to 1402 mg m-2 day-1) and declining in winter (3 to 28 mg m-2 day-1). Similarly, infalling invertebrates increased in summer (413 to 679 mg m-2 day-1) and declined in winter (11 to 220 mg m-2 day-1). Biomass measurements are indications of quantity that ignore nutritional quality, so I determined the bidirectional flow of invertebrates using absolute concentrations of physiologically important biochemical compounds (essential and polyunsaturated fatty acids). The fluxes of emergent and infalling arthropods peaked in summer (emergence = 0.3 to 18 mg m-2 day-1 and terrestrial infall = 0.3 to 3 mg m-2 day-1) and declined in winter (emergence = 0.01 to 0.51 mg m-2 day-1 and terrestrial infall = 0.01 to 0.03 mg m-2 day-1). However, during some seasons, no significant differences in polyunsaturated fatty acid flux in either direction were observed; this finding indicated the balance of reciprocal subsidisation via reciprocal flows of animals. Factors such as air temperature and algal productivity affected the reciprocal flows between adjacent habitats, with algal productivity being positively related to emergence while air temperature was positively correlated to infalling terrestrial invertebrates. This research enhances the growing body of literature on the function of riverine systems and offers some invaluable information on the flow of energy and the role played by invertebrates in translocating nutrients from terrestrial systems to aquatic systems and vice versa. This study unifies the concepts of the RCC and RPM and shows that these concepts are not limited only to large rivers, but are applicable to small southern temperate rivers too. However, some tenets of the theoretical models were challenged. For example, it challenges the proposition by the RCC that the fine particulate organic matter leaked from upstream breakdown of coarse particulate organic matter is predominantly allochthonous. Additionally, this study showed that in the headwaters, the RPM underestimated the role of autochthony. Overall, the results showed that the Kowie River and its riparian area are intrinsically connected. Once we understand the mechanisms controlling connections and subsidies across ecotones, we can then start to predict the consequences of disruptions to these connections by climate change and/or land use changes. To make predictions about future perturbations to rivers and riparian zones, studies like this, which considers the form and magnitude of subsidies, are needed to provide baseline information. Algal resources (e.g. epiphyton), macrophytes, riparian plants, terrestrial organisms and aquatic organisms all contributed to aquatic and terrestrial linkages in the Kowie River; therefore, it is important to conserve the different components of these ecosystems.]]> Wed 12 May 2021 16:03:58 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:27651 Wed 10 Aug 2022 07:12:52 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:29858 Wed 08 May 2024 18:39:13 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:29502 Wed 08 May 2024 18:06:22 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44780 Wed 08 May 2024 15:38:00 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:50883 Wed 08 May 2024 15:17:16 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:50757 Wed 08 May 2024 15:16:32 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:50831 Wed 08 May 2024 15:15:58 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44785 Tue 19 Oct 2021 14:38:28 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44782 Tue 19 Oct 2021 14:08:27 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44781 Tue 19 Oct 2021 13:15:53 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44777 Tue 19 Oct 2021 12:37:18 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44773 Tue 19 Oct 2021 12:21:30 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:43802 Tue 18 Jul 2023 22:13:02 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38063 Tue 14 May 2024 14:59:57 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:30485 Tue 14 May 2024 11:25:19 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44271 80% NVP was released from the tablets over the test period.
