Diversity and variation, related to Figure 2

(A) UMAP of taxonomic profiles colored by climate classification.

(B) UMAP of taxonomic profiles colored by surface type.

(C) UMAP of functional profiles colored by region.

(D) Taxonomic shift over time in cities with two years of sampling. UMAP dimensionality reduction of taxonomic profiles for each sample shows variation within cities across time (2016, circles and 2017, triangles) though generally less variation than between cities (colors).

(E–G) Sources of variation for AMRs. Association of the first 25 principal components of AMR genes with climate, region, and surface material.
