Abstract

Uncovering the role of environmental factors and finding critical factors which harbor significant fractions in governing microbial communities remain key questions in coastal marine systems. To detect the interactions between environmental factors and distributions of virio- and bacterioplankton in trophic coastal areas, we used flow cytometry to investigate the abundance of virio- and bacterioplankton covering 31 stations in the Bohai Sea of China. Our results suggested that the average abundance of total virus (TV) in winter (similar to 2.29x10(8)particles/mL) was slightly lower than in summer (similar to 3.83x10(8)particles/mL). The mean total bacterial abundance (TB) was much lower in winter (similar to 2.54x10(7)particles/mL) than in summer (similar to 5.43x10(7)particles/mL). Correlation analysis via redundancy analysis (RDA) and network analysis among virioplankton, bacterioplankton and environmental factors revealed that the abundances of viral and bacterial subpopulations depend on environmental factors. In winter, only temperature significantly influenced the abundances of virio- and bacterioplankton. In summer, in addition to temperature, both salinity and nutrient (SiO2) had a remarkable impact on the distribution of virio- and bacterioplankton. Our results showed a clear seasonal and trophic pattern throughout the whole water system, which revealed that temperature and eutrophication may play crucial roles in microbial distribution pattern.
