Kriged maps illustrating the spatial variability of the ratio of relative abundance of non-neutrally (sum of above-prediction and below-prediction) distributed ZOTUs to that of neutrally distributed ZOTUs (defined by the neutral model) in total bacterial communities or seven taxonomic groups. The colors of the stations correspond to different zones, and the stations in the Zhoushan archipelago were grouped into three subzones including ZSI_north (northern part of the archipelago), ZSI_mouth (in the mouth of HZ), and ZSI_other (others), which were shown as square, circle, and triangle symbols, respectively
