“…This finding showed that wood was the most liked substrate to be inhabited by periphyton among others. This result also in line with Signor et al (2015), which reported that wood, was the most liked substrate for periphyton, and this presumably due to the use of substrate for the production of organisms as a source of food.…”

Periphyton indeed plays an undeniably vital role as primary producers in the food web within aquatic ecosystems such as rivers. The existence of periphyton will affect the populations of the aquatic organisms at higher trophic level, thus it is interesting to be explored, especially in big rivers like Citarum. This study aimed to explore the distribution of periphyton, including its types and abundance at several stations in the upstream part of Citarum River based on the land use in the riverbanks, in the dry season of 2018. Samples were taken at nine stations, namely Gunung Wayang Springs, Outlet Cisanti at the valley of Mount Wayang, and the connecting tributaries as follows: Cihejo, Cibuni, Cirasea, Cikaro, Cisangkuy, Cikapundung, and Ciwidey. Samples of periphyton were taken from the substrate of stone, wood, plastic, and macrophytes at three sampling points of each station. Periphyton samples were then scraped off from the surface of the substrate, where the deposit would then be filtered using plankton net No.20, preserved with Lugol 1% and subsequently identified. The results showed there were 83 species from 58 genera of both phytoperiphyton and zooperiphyton, classified as periphyton found on the sites. The total abundance of phytoperiphyton ranged between 2.3 x 104 ind/m2 and 1.3 x 108 ind/m2 where the total abundance of zooperiphyton covered from 4.7 x 102 ind/m2 to 3.7 x 105 ind/m2. The highest and the lowest numbers of total abundance of periphyton were shown at stations of Gunung Wayang Spring and Cirasea tributary, respectively.

“…Due to this, species richness showed a significant variation between rainy and dry periods, with higher values associated with the rainy season. The periphytic community, in general, presents a clear spatial and temporal heterogeneity, which influences the variation of the composition, density, productivity, and biomass [41].…”

Periphyton communities are composed of microorganisms loosely attached to the substrate, including fungi, bacteria, microinvertebrates, and mostly microalgae. Due to their photosynthesizing component, they are important primary producers that subsidize the aquatic trophic chain. This study aimed to verify the composition, frequency, and seasonal distribution of periphytic microalgae in stretches of the Curiaú River, located in the Environmental Protection Area (APA) of the Curiaú River, in the State of Amapá. For this, quarterly collections were carried out comprising the months of June 2016 to October 2017, during the dry and rainy seasons. The periphyton algal communities were obtained by squeezing parts of two macrophytes species, Eichhornia crassipes Mart. (Solms) and Pistia stratiotes L. The data were statistically treated using absolute values and the Kruskal-Wallis test, the latter considering the distribution of richness between sites and sampling periods (significance level of α=0.05). A total of 64 taxa were inventoried, aggregated into three taxonomic divisions: Chlorophyta (n=48; 75%), Cyanophyta (n=12; 18.75%) and Heterokontophyta (n=4; 6.25%). In class terms, Zygnematophyceae had the highest number of taxa (n=42; 65.63%), followed by Cyanophyceae (n=12; 18.75%), Chlorophyceae (n=5; 7.81%), Bacillariophyceae (n=4; 6.25%) and, finally, Ulvophyceae (n=1; 1.56%). Of the total number of inventoried taxa, 64.06% (n=41) presented sporadic frequency. Species richness was influenced by seasonality, as higher values were associated with the rainy season (p<0.05). This research is a contribution to the phycology of the Amazon region, especially in its pioneering for the state of Amapá.
