Standardized total effects, model correlations, and observed correlations from the best-fit structural equation model (SEM) in which all paths were free to vary between the drought year of 2002 and the wet year of 2003.

<p>Differences between observed and model correlations give specific estimates of residual error in model fit. Total effects are the sum of all direct and indirect effects between predictor and response variables, where indirect effects are the product of all direct effects along a hypothesized casual pathway. Coefficients in bold differed from 0 based on 1000 bootstrap replicates.
