“…(a) (b) 2a). The high number of Bacillariophyta was also found in several other studies in Segara Anakan Lagoon [4,5,6]. Research in several rivers shows that the number of Bacillariophyta is higher than other phyla, such as in Baldi Stream, Garhwal Himalayas [17], Manna River, South Bengkulu [18], and Bedog River, Yogyakarta [19].…”

“…The abundance of phytoplankton in the Segara Anakan Lagoon and the Cibeureum River ranges from 38-4,037 individuals L -1 , this value indicates a low to moderate value based on [22]. The abundance of phytoplankton in the Donan River in 2019 in the rainy season was 1,695 individuals L -1 , and the dry season 1,133 individuals L -1 [5], while the abundance in the eastern area of the Segara Anakan Lagoon in 2018 ranged from 604-2931 individuals L .-1 [4]. The composition of phytoplankton based on abundance shows that St 1 to St 6 is dominated by Bacillariophyta, the value reaches 100% at St 1, St 2, and St 4.…”

“…Seasons will also affect the variation in the fertility of the lagoon waters because the input to the lagoon will be different in the rainy and dry seasons, this will also affect the composition and abundance of phytoplankton. The condition of water quality in the eastern part of Segara Anakan 1062 (2022) 012013 IOP Publishing doi:10.1088/1755-1315/1062/1/012013 2 Lagoon is strongly influenced by surrounding activities and input from surrounding rivers, which in turn affects the abundance of phytoplankton [4], the composition and abundance of phytoplankton in the Segara Anakan Lagoon varies between the rainy and dry seasons [5]. Total dissolved solids, pH, and nitrite greatly affect the abundance of phytoplankton [4], temperature, salinity, dissolved oxygen, nitrate, orthophosphate, and brightness affect the structure of the phytoplankton community [6].…”

“…This lagoon is the estuary of several major rivers in the Segara Anakan area, in the west, there are three rivers, namely the Citanduy River, Cibereum River, and Cikonde River, while in the east, there are the Sapuregel River, Donan River, and the Yasa River. Observations in the eastern Segara Anakan Lagoon show that the presence of phytoplankton is strongly influenced by water quality conditions, and the most important phytoplankton is Oscillatoria limosa which has a very high contribution [4,5,6]. The Bacillariophyta group is the group with the highest number of species and the highest abundance in the Segara Anakan Lagoon [4,5,6,7], and no species of phytoplankton dominate in this water [7].…”

Segara Anakan Lagoon and Cibereum River are located south of Java Island, precisely on the border between West Java Province and Central Java. This study aimed to reveal phytoplankton community structure related to water quality. Observations were made in May 2021 at seven locations. Ten liters of water were filtered using a plankton net with a mesh size of 53 μm and preserved using Lugol. The parameters observed were the abundance and composition of phytoplankton, dissolved oxygen, pH, temperature, turbidity, conductivity, total dissolved solids, and salinity. Phytoplankton community structure was analyzed using the Diversity Index, Evenness Index, and Dominance Index. The phytoplankton found consisted of Bacillaryophyta, Chlorophyta, Cyanophyta, Dinophyta, and Euglenophyta. Bacillaryophyta had more diversity of species than other phyla, with an abundance range from 38–4,037 individuals/L. Station 7 (at Cibereum River) had a different phytoplankton composition, with a higher abundance and species number, and Oscillatoria sp. as a dominant species. This station has low diversity and evenness index values (0.649 and 0.054, respectively), and the dominance index close to 1 (0.858) indicated unstable habitat for the phytoplankton community. Dissolved oxygen, pH, conductivity, total dissolved solids, and salinity were lower, while turbidity was higher than other stations.

Phytoplankton community characterized by strong vitality response to environmental change in freshwater ecosystems. This study aims to evaluate the effectiveness of using phytoplankton diversity as a water quality indicator in wetlands, and find out the main environmental variables affecting the distribution of phytoplankton. From 2020 to 2021, we examined phytoplankton assemblages and water environmental variables in spring, summer, and autumn at eight sampling sites from Hulanhe Wetland, Northeast (NE) China. The results showed that Bacillariophyta was the dominant species. Phytoplankton composition and abundance differed among sampling sites in each season; the abundance in summer (613.71 × 104 ind. L–1) was higher than that in autumn and spring. The water quality assessment of the trophic state index (TSI) based on the four physicochemical indicators was compared with phytoplankton diversity indices, which indicated that the phytoplankton community was stable, and these two indices were significantly lower in summer than in spring and autumn. According to redundancy analysis (RDA), total phosphorus (TP) and nitrogen (TN) were the main environmental variables affecting the distribution of phytoplankton. Temperature and dissolved oxygen (DO) changes also played a role, and their impact on the community was discussed. This work can provide relevant scientific references on the usefulness of phytoplankton diversity structure in assessing water quality in cold regions, in which the succession can be significantly affected by nutrients and temperatures.
