Fig. 8: Inter-omics Procrustes biplots comparing PCA ordinations of metabolite class profiles and microbiome genera based on centered log ratio (CLR) transformed data.

A Full data set including all four sponge species (n = 37) and B Sponge species panels: Chondrilla nucula (n = 10), Chondrosia reniformis (n = 10), Crambe crambe (n = 9), Petrosia ficiformis (n = 8). There was significant overall correlation between the microbiome and the metabolome when considering the full dataset comprising all four sponge species, however this association faded at the single species.
