Compositional data analysis of Plastisphere. A Clustered abundance heatmap of CLR values using Aitchison distance and 1 − ρ as sample and taxon distance metrics, respectively, followed by average linkage hierarchical clustering. B Differential co-occurrence hive network between mature and early plastic biofilms using ρ proportionality as the association matrix with positive and negative differential connectivity colored as red and blue, respectively. C Heatmap of differential connectivity values in the hive network
