(a) Maximum likelihood phylogenetic tree showing environmental characteristics and habitat predictions. Characteristics of the sampling locations are plotted on the inner and outer rings: the inner ring indicates the phylogroup, the intermediate ring indicates high (≥35 ppt), medium (32≤ salt ≤35) or low (<32 ppt) salinity and the outer ring indicates the microenvironment (according to the identified habitat C1 to C5 in the MRT analysis). Ecological habitats predicted by the model are identified by colored circles at the parent nodes on the tree. Ecoclades which contained at least 10 pufM sequences and passed a post hoc empirical significance threshold (P-value < 0.01) are indicated by alternating blue and gray shading of clusters. (b) The distribution of each habitat among microenvironments and salinity. The habitat and environment colors match the legend in (a).
