| Summary: | Coefficients are shown for each pathway, and correlated error structures based on the independent effects of CO 2 enrichment on primary producer (“turf”) biomass, food abundance (gastropod prey), and food intake for male and female common triplefin, crested blenny, blue-eyed triplefin, and Yaldwyn’s triplefin. The sample size ( N ), adjusted model R 2 , and other specifications of each LM used in the piecewise SEM are also provided. Fisher C is a test of the conditional independence of the model and any missing pathways that should be added to the model, with the model significance (Model p) indicating missing pathways (missing if p < 0.05). AIC of the individual and combined effects of CO 2 enrichment and food abundance on food intake. Significant p -values are indicated in bold. AIC, Akaike information criterion; LM, linear model; SEM, structural equation model. (PDF)
