Seasonal dynamics of mycoplankton in the Yellow Sea reflect the combined effect of riverine inputs and hydrographic conditions

Little is known about how multiple factors including land‐based inputs and ocean currents affect the spatiotemporal distribution of the mycoplankton in coastal regions.

Description
Summary:Little is known about how multiple factors including land‐based inputs and ocean currents affect the spatiotemporal distribution of the mycoplankton in coastal regions. To explore the seasonal changes of mycoplanktonic communities and potential environmental drivers, we collected water samples from the Yellow Sea, used here as a model for subtropical sea habitats, in different seasons over two years. Compared with winter and spring, summer exhibited higher levels of fungal richness and community heterogeneity in the water column. The seasonal shifts in mycoplankton diversity and community composition were mainly ascribed to freshwater inputs, the Cold Water Mass and invasion of the Yellow Sea Warm Current. Among the physicochemical variables tested, temperature was the primary determinant of fungal diversity and showed contrasting influences on fungal richness in the surface and bottom waters during summer. In addition, we provide evidence for the community similarity and dissolved nutrients of different water bodies to highlight the potential origin of the Cold Water Mass. Our findings bring new understanding on the factors determining the dynamics of mycoplankton communities by modelling the influence of physicochemical variables and tracking the geographical distribution of certain fungal taxa.
