GTF -OTU-distribution. (A) Dendrogram displaying the assignment of 12 geographic regions using the Pearson Distance correlation analysis based on gtf-OTU-distribution; (B) heatplot displaying OTU-types and their distribution across 12 geographic locations. OTU-types are defined according to their presence in only one or multiple countries (white, 0% presence, black, 64% presence). By way of example, the upper six countries are characterized by dominance of OTUs, which are distributed over 11 countries (red square), while the lower six countries are comparably high in OTUs confined to a single geographic location (blue square).
