Pearson correlations between predictor variables seagrass carbon:nitrogen (C:N) ratios,
seagrass carbon:phosphorus (C:P) ratios, temperature, and salinity (all n = 48), and
herbivorous fish abundance (square root transformed, n = 24). Single (*) or double
(**) asterisks indicate significant correlations at the 0.05 and 0.01 levels, respectively.
