Fine-scale taxonomic composition shifts across time. Fine-scale compositional changes of halite communities over time shown with (a) hierarchical clustering (correlation metric) of an Unweighted Unifrac dissimilarity matrix (based on 16S rRNA gene amplicon sequencing), (b) hierarchical clustering (Euclidean metric) of standardized MAG abundances, (c) PCA of co-assembly contig abundances, and (d) weighted distributions of taxonomic turnover (TTI) of functional niches between time points. The TTI of each functional category estimates the changes in organisms that encode it (see the Methods section)
