Extended Data Fig. 6: Latitudinal variation across the SAR11-IIIb clusters.
From: Ecophysiology and global dispersal of the freshwater SAR11-IIIb genus Fontibacterium
Box plots show the latitudinal distribution for each of the nine distinct clusters identified from n = 307 metagenomes (see Extended Data Fig. 5). The number of individual metagenomes assigned to each cluster (n) is indicated below the x-axis label. Box plots display the median (center line) and interquartile range (IQR; box), and whiskers extend to the furthest data point within 1.5 × IQR of the hinge, with outliers plotted individually. An overall difference in latitude among the nine clusters was tested using a Kruskal-Wallis test (P = 2.2e-16).
