Results of the investigation indicated that the microheterotrophs represented the most important consumers of bacteria and chlorophyll (chl)-a <5.0 μm. The low impact of the mesozooplankton on the bacteria and chl-a <5.0 μm during the study appeared to be related to the inability of the larger zooplankton to feed efficiently on small particles. During those periods when total chl-a concentration was dominated by picophytoplankton (<2.0 μm) and microphytoplankton (>20 μm), mesozooplankton were unable to feed efficiently on the chl-a due to feeding constraints. In response to the unfavorable size structure of the phytoplankton assemblages, mesozooplankton appeared to consume the microheterotrophs. The negative impact of the mesozooplankton on the microheterotrophs resulted in a decrease in the impact of these organisms on the bacteria and the chl-a <5.0 μm. This result is consistent with the predator-prey cascades. On the other hand, when the total chl-a was dominated by nanophytoplankton (2–20 μm), mesozooplankton were able to feed directly on the phytoplankton. Results of the study indicate that size structure of the phytoplankton assemblages within estuaries plays an important role in mediating the trophic interactions between the various components of the plankton food web.]]> Thu 25 Apr 2024 15:44:49 SAST ]]> Effects of temperature and salinity on the standard metabolic rate (SMR) of the caridean shrimp Palaemon peringueyi https://commons.ru.ac.za/vital/access/manager/Repository/vital:6831 35‰ suggests that the shrimp may experience osmotic stress in freshwater deprived permanently open and intermittently open estuaries where hypersaline conditions may develop.]]> Thu 25 Apr 2024 15:43:48 SAST ]]> Regional calibration of the Pitman model for the Okavango River https://commons.ru.ac.za/vital/access/manager/Repository/vital:7085 Thu 16 May 2024 08:36:20 SAST ]]> Impact of climate change and development scenarios on flow patterns in the Okavango River https://commons.ru.ac.za/vital/access/manager/Repository/vital:7086 Thu 16 May 2024 08:35:47 SAST ]]> Estimating rainfall and water balance over the Okavango River Basin for hydrological applications https://commons.ru.ac.za/vital/access/manager/Repository/vital:7084 Thu 16 May 2024 08:34:32 SAST ]]> Comparison of satellite rainfall data with observations from gauging station networks https://commons.ru.ac.za/vital/access/manager/Repository/vital:7079 Thu 16 May 2024 08:33:43 SAST ]]> A generic database and spatial interface for the application of hydrological and water resource models https://commons.ru.ac.za/vital/access/manager/Repository/vital:7080 Thu 16 May 2024 08:33:04 SAST ]]> Exploitation status of infralittoral abalone (Haliotis midae) and alikreukel (Turbo sarmaticus) in the southern section of the Eastern Cape coast, South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:6915 Thu 16 May 2024 05:39:21 SAST ]]> Oceanographic environment of the Sodwana Bay coelacanths (Latimeria chalumnae), South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:7156 Thu 15 Jul 2021 21:37:35 SAST ]]> African Coelacanth Ecosystem Programme: An overview of the conference contributions https://commons.ru.ac.za/vital/access/manager/Repository/vital:7127 Thu 15 Jul 2021 21:37:33 SAST ]]> Olive Schreiner at 150: some thoughts on re-editing Cronwright's The Reinterment on Buffelskop https://commons.ru.ac.za/vital/access/manager/Repository/vital:6124 Thu 13 May 2021 07:29:59 SAST ]]> Novel amperometric glucose biosensor based on an ether-linked cobalt(II) phthalocyaninecobalt(II) tetraphenylporphyrin pentamer as a redox mediator https://commons.ru.ac.za/vital/access/manager/Repository/vital:6583 Thu 13 May 2021 07:16:44 SAST ]]> Language and learning science in South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:7023 Thu 13 May 2021 06:50:26 SAST ]]> Lattice-valued continuous convergence is induced by a lattice-valued uniform convergence structure https://commons.ru.ac.za/vital/access/manager/Repository/vital:6824 Thu 13 May 2021 06:39:33 SAST ]]> Electrocatalysis of oxidation of 2-mercaptoethanol, L-cysteine and reduced glutathione by adsorbed and electrodeposited cobalt tetra phenoxypyrrole and tetra ethoxythiophene substituted phthalocyanines https://commons.ru.ac.za/vital/access/manager/Repository/vital:6593 Thu 13 May 2021 04:28:09 SAST ]]> The South African coelacanths — an account of what is known after three submersible expeditions https://commons.ru.ac.za/vital/access/manager/Repository/vital:7131 Thu 13 May 2021 04:10:36 SAST ]]> The Bellman's tale - Part 1 https://commons.ru.ac.za/vital/access/manager/Repository/vital:6989 Thu 13 May 2021 03:42:23 SAST ]]> Interactions of fishes with particular reference to coelacanths in the canyons at Sodwana Bay and the St Lucia Marine Protected Area of South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:7130 Thu 13 May 2021 03:38:40 SAST ]]> Fishes of the deep demersal habitat at Ngazidja (Grand Comoro) Island, Western Indian Ocean https://commons.ru.ac.za/vital/access/manager/Repository/vital:7128 Thu 13 May 2021 03:09:03 SAST ]]> The Johannesburg project https://commons.ru.ac.za/vital/access/manager/Repository/vital:6167 Thu 13 May 2021 02:20:01 SAST ]]> Academic Library Consortia in South Africa : where we come from and where we are heading https://commons.ru.ac.za/vital/access/manager/Repository/vital:6987 Thu 13 May 2021 01:44:32 SAST ]]> Critical media literacy: a design for the future https://commons.ru.ac.za/vital/access/manager/Repository/vital:6331 Thu 13 May 2021 01:34:41 SAST ]]> Will the invasive mussel Mytilus galloprovincialis Lamarck replace the indigenous Perna perna L. on the south coast of South Africa?
