Macrogenome Summer and Winter
This study aims to investigate the seasonal succession and structural dynamics of marine microbial communities in a typical sub-tropical semi-enclosed bay during summer and winter. Coastal ecosystems are increasingly threatened by land-based pollutant discharges and eutrophication, which profoundly alter local biogeochemical cycling and microbial ecology. By employing metagenomic sequencing, we analyze the spatiotemporal variations of key microbial taxa (such as Proteobacteria, Actinobacteria, and Bacteroidetes) in response to seasonal environmental gradients, including temperature, salinity, and nutrient loading. The findings will provide crucial insights into the microbially driven biogeochemical mechanisms in coastal waters, ultimately offering a scientific basis for marine ecological health assessment, environmental carrying capacity evaluations, and targeted ecological restoration strategies.
