Fig. 3. Baseline fungal composition influences final community composition.
Differences in fungal community composition and diversity present on arrival from the four laboratory mouse vendors lead to persistent differences in the composition and diversity of fungal communities (a–d). Hypothesis testing for community composition was performed using permutational multivariate ANOVA and canonical correspondence analysis of Hellinger transformed Bray–Curtis dissimilarity distances and community diversity by ANOVA of the Chao1 index. CCA canonical correspondence analysis, OTUs operational taxonomic units, PERMANOVA permutational multivariate ANOVA, PCoA principal coordinates analysis.
