Figure 2. Final structural equation model (SEM) showing the direct and indirect effects of predictors on demersal fish biomass averaged across model runs (conducted at the broader spatial scales for each time period; Figure S2.4). The color and thickness of the arrows shows the sign (blue arrow = positive, red oval = negative) and strength of each relationship based on linear scaling of the mean standardized coefficients across model runs. The coefficient of determination (R2) is also indicated for each response variable. We removed the grey predictor variables and pathways in the final SEM to limit the number of predictors relative to the number of observations and to assess goodness-of-fit.
