Abstract

An essential function of phytoplankton is to facilitate the movement of materials, energy, and information within mangrove ecosystems. Because they are sensitive to changes in the ambient conditions of aquatic bodies, phytoplankton is frequently employed for environmental monitoring in aquatic ecology. By sampling at six stations in October (the normal season) and December (the dry season) in 2020, the spatial and temporal variations of phytoplankton as well as the effects of environmental variables on phytoplankton community structure were evaluated in order to better understand the dynamics of the phytoplankton community in Dongzhai Harbor Mangrove Reserve, Haikou, China. The findings demonstrated that phytoplankton's species richness, cell density, and diversity revealed temporal and spatial change. During the normal season, green and blue-green algae predominated, but during the dry season, cryptophytes replaced them. The phytoplankton community's seasonal average dissimilarity was 58.23. The Dongzhai Harbor Mangrove Reserve's phytoplankton community was found to be impacted by water temperature, turbidity, and total nitrogen, according to RDA results. This is the first study simultaneously investigating the phytoplankton community and their environment in this area, and it is essential in order to set up the baseline for future studies.
