“…Bacillariophyceae adapts well to environmental conditions and has a high tolerance and adaptability, so this class is cosmopolitan [32]. However, on the other hand, Cyanophyceae has a high abundance for the genus Merismopedia, which is commonly found in freshwater [33] and seawater [34].…”

The connectivity between seagrass and mangrove ecosystems has synergistic benefits of conserving the land-sea ecosystems of the small islands. The physicochemical properties of the two ecosystems lead to the success of the habitat of the interconnected zone. This study aimed to analyze the physicochemical factors in the mangrove and seagrass ecosystems on Pramuka Island and understand the factors influencing the phytoplankton production of small island coastal ecosystems. Sediment and water collection were carried out on Pramuka Island, Indonesia, to measure physicochemical parameters. Mangrove and seagrass ecosystems have the highest DO, temperature, and pH values. The phytoplankton counts showed significant variation between the sampling sites with a predominance of the class Cyanophyceae. The estimated primary productivity of chlorophyll-a indicated that its concentration was higher in mangroves than in seagrass. A similar trend was observed in nutrient loads and dissolved inorganic nitrogen. Results of the present study clearly showed that an increased concentration of dissolved inorganic nutrient influence the concentration of chlorophyll-a as an indicator of primary productivity. These findings will provide a preliminary analysis of the physicochemical conditions and productivity on Pramuka Island.

“…The highest values were 4.6 (in Blue Nile). It was shown that abundance of phytoplankton during the dry season in waters is negatively correlated with nutrient concentration [26,5]. This is attributed to a depletion of nutrients as these were utilized by the phytoplankton for photosynthesis increasing their population size.…”

This study was conducted to estimate the distribution of phytoplankton, zooplankton and their correlation with physico-chemical conditions of water for White Nile, Blue Nile and River Nile, April – May 2022. Some of the important physico-chemical factors of the research stations have been analyzed and the water temperature (°C) were (22.00±1.00, 21.00±0.00 and 21.00±0.00), pH (8.47±0.31, 7.6.00±0.35 and 8.07±0.12) and Transperancy (cm) (34.67±11.06, 85.33±4.16 and 47.00±8.54) for White Nile, Blue Nile and River Nile respectivley. The results revealed that there are 18 species of phytoplankton and 18 species of zooplankton were recorded from all the stations. Among these Bacillariophyceae was the most dominant class in phytoplankton 5 genus, followed by 4 genus Chlorophyceae, 3 genus Cyanophyceae, 3 genus Zygnematophyceae, 2 genus Xanthophyceae and 1 genus Coscinodiscophyceae. While zooplankton, 18 different genera, the genus are represented by 6 genus Rotifera, 2 genus for (Crustacea, Rhizopoda, Lobosea and Eurotatoria), 1 genus for (Adenophorea, Phylactolemata, Secernetea and Ciliata). Statistically, phytoplankton showed significat result with zooplankton (r2 = 0.81) and with water temperature and PO4 (r2 =0.43); non-significant different with transperancy (r2 = 0.01); for zooplankton the results showed that the positive relation between zooplankton and turbidity (r2 =0.27) and non-significat with other parameters.
