Variation partitioning analysis of microbial distribution explained by environmental factors. (A) General outline; (B) test environmental parameters, including temperature (T), nutrients (N), and “salinity + pH value” (SP). Each diagram represents the variation partitioned into the relative effects of each factor or combination of factors, in which area is proportional to the respective percentages of variation explained. The edges of the triangles represent the variation explained by each factor alone. The sides of the triangles represent interactions of any two factors, and the middle parts of the triangles represent interactions of all parameters.
