Water and sediment chemistry drivers of chlorophyll-a dynamics within a Ramsar declared floodplain pan wetland system
Floodplain pans are hydrologically dynamic in nature and characterised by variables such as chlorophyll- a (chl- a ), water, and sediment chemistry over their hydroperiods. The present study investigated the spatio–temporal variations in water and sediment physico–chemical, and chlorophyll- a concen...

| description | Floodplain pans are hydrologically dynamic in nature and characterised by variables such as chlorophyll-
a
(chl-
a
), water, and sediment chemistry over their hydroperiods. The present study investigated the spatio–temporal variations in water and sediment physico–chemical, and chlorophyll-
a
concentration characteristics of six floodplain pans found in the Ramsar declared Makuleke wetlands, Kruger National Park, South Africa. The water and sediment physico–chemical variable values were generally elevated during the high-water period, whereas chlorophyll-
a
concentrations varied across pans and hydroperiod. Benthic chl-
a
concentration significantly varied across pans with concentrations ranging from 161 to 1036.2 mg m
2
. The two-way ANOVA showed significant differences in benthic chl-
a
concentration among hydroperiods, and no significant differences were observed in pelagic chl-
a
across pans and hydroperiods. Generally, pelagic and benthic chl-
a
concentration increased as water and sediment chemistry variables increased. Furthermore, three sediment variables, i.e. pH, calcium, and magnesium, and water conductivity were found to be significant in structuring benthic chlorophyll-
a
dynamics in pans. However, none of the sediment and water variables had a significant effect on pelagic chl-
a
. Hydroperiod had a significant effect on influencing chl-
a
concentration, with high and low water level periods being characterised by low and high chl-
a
concentration, respectively. The
n
–MDS results showed strong overlaps in chl-
a
biomass among the Makuleke floodplain pans across hydroperiods. The increasing chl-
a
concentration in these floodplain pans due to potential bioturbation effects as a result of large mammals could potentially lead to eutrophication, which in turn could affect the system’s primary productivity and aquatic biota. Therefore, it is important to establish a continuous monitoring programme on these pans to inform sound management decisions. |
