Results of the linear models for predicting chlorophyll <i>a</i> (ln), ranked in increasing order of AIC.

The highest ranked model of each diversity type is bolded. P values that are less than 0.05 are bolded. * Environmental variable model includes % tree cover, DIC, ln area, ln depth, pH, and ln DOC ** Environmental PCA includes first 2 axes of PCA on all standardized environmental variables.
