Fig. 2: Phylogenetic relationships and divergence times of the 13 Microcoleus lineages (indicated as M1-M13) along with genetic and ecological differentiation patterns among them.
From: The global speciation continuum of the cyanobacterium Microcoleus
a The dating of the divergence times among Microcoleus lineages is based on the 16S rRNA gene. Branches were collapsed, and the clades are color-coded according to the lineage designation. The blue bars represent 95% highest posterior density (HPD) values for each node. An asterisk denotes a node of the removed outgroup. The time axis is millions of years ago (MYA) with chronological dating of geological intervals. b Heatmap for pairwise FST distances between lineages. The color spectrum from blue to red illustrates genetic differentiation from low to high. c–f Differences in habitat preferences of lineages (n = 200 strains) for c precipitation of wettest month, d mean temperature of coldest quarter, e average solar radiation, and f volume of coarse soil fragments. Boxplots show the median, interquartile range, default whiskers, and outliers as points. Boxplot colors correspond to the lineages’ color codes.
