Fig. D1. Structural equation modeling indicating correlations among treatment (Anax size = small, medium, or large A. junius larvae added) and measured ecosystem response variables. nMDS1 and nMDS2 scores represent the community structure based on relative densities of species (see Fig. 4A in main text), Phytochange, Perichange, changeNPP, and changeResp indicate the relative change in Periphyton and Phytoplankton biomass, Net Primary Productivity (NPP) and respiration respectively measured within a tank over the course of the experiment. Only the final model with the best fit is indicated. Significant correlations (P > 0.05) are in red.
