Canonical Correspondence Analysis (CCA) of the relationship between zooplankton taxa and environmental variables. All variables (lake morphometry, environment, water chemistry, and land use) were analyzed, but only those that were statistically significant (p < 0.05) were retained. High complexity (piscivorous and planktivorous/benthivorous fishes), low complexity (planktivorous / benthivorous fishes) and fishless (no fishes) indicates the complexity of fish assemblages. The x- and y-axes explain 26% and 16% of the variation, respectively. Conductivity and salinity were omitted due to the strong correlation to TDS.
