“…nitrogen and phosphorus concentration) conditions which can strong influence the microphytoplankton abundance and composition in this ecosystem. These hypotheses are also supported by several studies carried out in many freshwater ecosystems, including artificial lakes and reservoirs, which demonstrate strong influence of spatial, physicalchemical and nutrient availability factors in structuring phytoplankton communities composition and distribution (Huszar et al 2015;Souza et al 2016;Maloufi et al 2016;Cardoso et al 2019Cardoso et al ,2017Kruk et al 2017;Rosa et al 2017;Weithoff & Gaedke 2017;Ribeiro et al 2018;Anneville et al 2019;Alves et al 2020b;Kutlu et al 2020).…”

The structure of freshwater phytoplankton communities can be strongly influenced by environmental and spatial processes at different scales. To identify the main forces that drive phytoplankton structure becomes a relevant tool to understand several knowledge gaps in the phytoplankton ecology domain, such as community succession, biological invasions and responses to disturbances. We used the morphological-based functional groups (MBFG) approach to investigate the influence of environmental conditions (physical and chemical factors), nutrient availability and spatial processes (habitat connection and species dispersal) in structuring microphytoplankton community in a subtropical hypereutrophic reservoir located in southern Brazil. Samples were taken quarterly, between February 2017 and December 2018. We used distance-based multivariate analysis of variance (PERMA-NOVA) to evaluate potential spatial and seasonal dissimilarities in the MBFG's biovolume, and variation partitioning approach (pRDA) to evaluate the role of environmental, nutrient availability and spatial components in explain the microphytoplankton community structure. We identified 16 microphytoplankton taxa, which were sorted into five MBFGs. Significant seasonal dissimilarities were observed in the MBFG's biovolume. Higher relative biovolume of potential harmful cyanobacteria (MBFG III) and alien dinoflagellates (MBFG V) was observed in summer and autumn/winter, respectively. Pure environmental component (composed by physical and chemical predictors insolation, precipitation, total dissolved solids, turbidity, water temperature, water transparency and wind intensity) explained 45% of the variance in the MBFG's biovolume, whereas pure nutrient availability component explained 7% and spatial component explained only 3% of the biotic variance. The results showed that the environmental factorsespecially the seasonal-influenced onesare more effective than nutrient availability and spatial processes in explaining the microphytoplankton community structure in this ecosystem. Our findings alert to the need to consider the variability of the environmental conditions (mainly those directly influenced by seasonality) in phytoplankton community structure in disturbed freshwater ecosystems prone to eutrophication events.

“…Based on some research, Chlorophyceae class can be found mostly in lake waters (Giripunje et al 2013;Muhtadi et al 2015;Öterler 2018), including in a coastal or brackish lake (Nassar and Gharib 2014;Pratiwi et al 2018a), estuaries (Dewi et al 2019;Yang et al 2019). However, Obolewski et al (2018) and Cardoso et al (2019) found that plankton in a coastal lake which lacks nutrient is dominated by Cyanobakteri reaching until 80%. Nonetheless, in coastal lakes that tend to be saltier phytoplankton is generally dominated by Bacillariopyceae (Onyema 2008;Srichandan et al 2015;Mukherjee et al 2018;Yilmaz et al 2018;Cutrim et al 2019) and Dinophyceae (Hasudungan et al 2008), including in coastal waters (Ajibare et al 2019).…”

Abstract. Muhtadi A, Pulungan A, Nurmaiyah, Fadlhin A, Melati P, Sinaga RZ, Uliya R, Rizki M, Rohim N, Ifanda D, Leidonald R, Wahyuningsih H, Hasani Q. 2020. The dynamics of the plankton community on Lake Siombak, a tropical tidal lake in North Sumatra, Indonesia. Biodiversitas 21: 3707-3719. The tidal lake is a very dynamic estuary ecosystem and very vulnerable to environmental stresses and disturbances. Plankton is an aquatic organism that is very easily affected by environmental pressures and disturbances. This study aimed to reveal the phenomenon of plankton dynamics in tropical tidal lakes in Indonesia. The study was conducted at Siombak Lake from September 2018 to August 2019. Data were collected at high and low tides every month during the full month. The data analysis included plankton abundance, diversity index, and the relationship between water quality and plankton with PCA and succession analysis. The results showed that in Siombak Lake was found 66 genera which consisted of 54 phytoplankton genera and 12 zooplankton genera. Plankton abundance is higher in parts of the lake (stations 1-8) than in the river (stations 9-11) at both high and low tide. Temporally it shows that plankton abundance is higher in the rainy season (Feb-Aug, outside May) than in the rainy season (Sep-Jan, and May). Spatially, plankton in Siombak Lake at high tide is more influenced by TSS, phosphate, and salinity, while at low tide, it is influenced by TSS, Water transparency, BOD, silicate, salinity, and dissolved oxygen. Temporally, plankton in Siombak Lake at high tide is more influenced by salinity, conductivity, Debit, TSS, and salinity, while at low tide, it is influenced by salinity, conductivity, turbidity, TSS, TDS, DO, BOD, and COD. Based on the plankton Frontier succession graph, it shows that Siombak Lake is included in stage 1 and stage 2. Stage 1 occurs before the rainy season (August-September) and the peak of the dry season (March-April).

“…Similarly, planktonic algae may settle and attach to substrates when river flow is slow (Roeder, 1977;Tekwani et al, 2013). On the other hand, although planktonic and benthic algae occupy different habitats, they compete for abiotic resources, especially for light and nutrients (Hansson, 1988;Jäger & Diehl, 2014;Cardoso et al, 2019). Planktonic algae have the competitive advantage of light through reducing light transmission to benthic habitat while benthic algae have the advantage of nutrient utilization because they can absorb nutrients from both water volume and sediments (Hansson, 1990;Jäger & Diehl, 2014;Zhang & Mei, 2015).…”

Comparing the spatio-temporal patterns between planktonic and benthic diatoms is helpful to understand biodiversity patterns and drivers in rivers. However, such studies are still rare especially in mountain regions. We used a dataset collected in the upper reach of the Jinsha River in different seasons to explore biodiversity and assembly processes of planktonic and benthic diatom assemblages. We found that planktonic and benthic diatoms presented different seasonal variation in species richness and community composition. We also found evidence that planktonic and benthic diatoms were coupled especially in the summer. Planktonic diatom assemblages were mainly affected by spatial processes (mainly directional spatial processes) in both seasons.The effects of environmental processes were significant in the autumn, but were almost negligible in the summer. By comparison, benthic diatom assemblages were more affected by environmental factors than spatial processes. Our results suggested that mass effect and species sorting paradigms explained the assembly processes of planktonic and benthic diatom assemblages, respectively, but the explanatory powers of these two paradigms varied seasonally. To effectively monitor and assess river environmental conditions, we recommend using benthic algae as a biotic indicator group as they seem to better reflect environmental conditions in rivers.
