The probability (p) of significant relationships between taxa abundance and SOI was tested across all data using ANOVA with F statistic.
Only taxa where correlation coefficients were detected in two or more sites within a habitat are presented. Bold text and values highlight where significant (p < .05) relationships exist between SOI and taxa abundance when all site data are pooled within a habitat.
