Characteristics of Phytoplankton Biomass, Primary Production and Community Structure in the Modaomen Channel, Pearl River Estuary, with Special Reference to the Influence of Saltwater Intrusion during Neap and Spring Tides

Abstract: In recent decades, increasing frequency and intensity of saltwater intrusion in the Modaomen Channel has threatened the freshwater supply in the surrounding cities of the Pearl River Estuary, and ulteriorly changed the environmental conditions of the estuarine waters. Phytoplankton biomass, primary production (PP) and species composition, as well as hydrological and chemical parameters were examined along a downstream transect in the Modaomen Channel during neap tide (NT) and spring tide (ST), when a strong sa… Show more

“…Rhizosolenia styliformis Brightwell and C. siamense Ostenfeld are species that can adapt to high salinities and varying temperatures and could have been transported to the study area from the open sea by tidal currents. The phytoplankton taxa predominantly detected in the study area belonged to the widely distributed offshore group, and these results are consistent with those reported in previous studies [28,37].…”

“…In the last decade, numerous studies have been performed on the ecology of phytoplankton in the Pearl River Estuary and its adjacent waters in China, and these have discussed the ecological characteristics of phytoplankton, mechanism of red tides, and grain size structure and spatial distribution of primary productivity [21][22][23][24][25][26][27][28][29]. However, there is still a lack of research on the community structure of phytoplankton and the relationship between phytoplankton and environmental factors in the waters around Macau.…”

“…However, high abundance of Cyanobacteria was found in summer which was consistent with what was observed in earlier study ( Barz et al, 2010 ). The high abundance of Cyanobacteria was found to be highly impacted by temperature, salinity, and phosphate, which likely promoted the growth of Cyanobacteria in the coastal sea ( Zhou et al, 2016 ).…”

“…The phytoplankton community composition in the São Marcos Bay revealed diatoms as the most successful phytoplankton group (e.g., growth and abundance). The wild occurrence of diatoms in coastal ecosystems is based on their euryhaline nature and affinity for favorable high nutrient environments (Paiva et al, 2006;Rodrigues and Cutrim, 2010;Zhou et al, 2016).…”
