Algoa Bay, situated on the warmtemperate south-east coast of South Africa presents a unique opportunity to study key elements of plankton ecology relevant to climate change problems in the regional sense. The embayment is locally subjected to frequent wind-driven upwelling and regionally, to periodic mesoscale oceanographic forcing (e.g., large solitary meanders, Agulhas Current intrusions), all of which culminate in a complex physical and biogeochemical environment. Using zooplankton as the focal component and drawing from a multi-year monthly dataset incorporating a bay-scale sampling framework, the present study addressed three key hypotheses pertaining to 1) drivers of spatio-temporal variability, 2) biomass rate of change over temporal scales using time-series analyses, and 3) community responses to a bay-scale biological perturbation event. Zooplankton biomass exhibited prominent seasonal patterns with bimodal peaks corresponding with near-consistent year-to-year autumn and spring blooms. Overall, the spatial trend showed no heterogeneity, though statistical significance between-station variability was noted per season. An analytical framework involving generalised additive models revealed zooplankton spatial heterogeneity in Algoa Bay to be a function of seasonal variation in a suite of physicochemical variables, including the combined effects of temperature, salinity, dissolved oxygen, total nitrogen and silicate, but not ammonium, phosphate or chlorophyll-a (as proxy for phytoplankton). Fronts (including river plumes), warm water intrusion from the Agulhas Current, and wind-driven upwelling were postulated to be key driving forces. Structural breaks analysis performed on station-specific time series revealed significant incremental increases in zooplankton biomass over time, which in turn, corresponded with a gradual decrease in thermocline depth. The most pronounced increasing effect was associated with a period (2013– 14) of amplified land-derived nutrient input and increasing harmful algal bloom (HAB) activity.]]> Wed 10 Aug 2022 15:58:07 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:43149 Wed 09 Jun 2021 12:18:02 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:61086 Wed 08 Feb 2023 13:07:39 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:61140 Wed 08 Feb 2023 13:07:25 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45724 Wed 02 Mar 2022 10:25:24 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:51703 Wed 01 Jun 2022 10:25:52 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:41018 Tue 30 Nov 2021 08:34:14 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71414 Tue 30 Jan 2024 12:19:23 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:43250 Tue 28 Sep 2021 15:37:01 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72792 Tue 28 May 2024 11:02:00 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:72791 Tue 28 May 2024 10:46:28 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:62026 Tue 28 Feb 2023 13:08:47 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:61068 Tue 24 Jan 2023 15:44:58 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45347 0.05 evaluated for potential toxicity were categorised as toxic, but Albizia amara, Datura stramonium and Ricinus communis were categorised as having medium toxicity levels, nine species as having low toxicity levels while 13 species were categorised as non-toxic.

This species significantly altered the estuary's water quality, causing supersaturated surface- and hypoxic bottom-water during severe HABs or referred to as hypereutrophic bloom phases (> 60 µg Chl-a L -1 ). Despite these changes, the common copepod, Pseudodiaptomus hessei, occurred at similar densities among HAB phases and responded to similar triggers to the HAB. However, a shift in predator-prey interactions within the zooplankton community was evident, with scavenger or opportunist species such as the isopod, Cirolana fluviatilis, and the polychaete, Perinereis falsovariegata, occurring at higher densities during hypereutrophic bloom phases. The overall abundance of juvenile and small adult fishes were high during HABs, but the diversity decreased during HABs. Some species, notably the Mugilidae occurred at lower densities during HABs. Mugilidae also had pronounced histological gill alterations and a lowered proportion of secondary lamellae available for gas exchange during an in situ cage experiment where fishes were isolated inside and outside the HAB. Deformities such as tumorous growths were also found for the first time in a South African Estuary. This indicated a stressed population of Mugilidae in the Sundays Estuary. The ubiquitous mugilid, Mugil cephalus, actively avoided HABs during an acoustic telemetry study, despite having a home range that overlapped the HAB area. Tagged individuals mostly occupied areas directly above the HAB in the upper mesohaline to lower oligohaline zones and only iv briefly transitioned through the HAB area to utilise the lower reaches of the estuary. Since the formation of HABs is reliant on various factors, including specific species responses, environmental variables, nutrient enrichment, and flow characteristics, the impacts of HABs on estuarine communities may vary between estuarine systems or affected species. Therefore, more research that focuses on the impacts of HABs on estuaries is needed to limit the potential loss of ecosystem services. Particularly in light of further unsustainable development, upstream freshwater abstraction and climate change, will cause more frequent and severe HABs, that may result in fish population declines in the long-term. Better management and mitigation strategies are needed to reduce HAB formation such as reducing nutrient enrichment and restoring natural freshwater flow and flooding events to the Sundays Estuary.]]> Sat 06 Aug 2022 22:03:17 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:71962 0.5 mg/ml).
