Structural equation model of relationships in a southern California, USA, chaparral ecosystem with variable fire histories from 2003 to 2015. Positive relationships are displayed with solid lines and negative relationships with dashed lines. Line thickness corresponds to the magnitude of standardized estimates¬†(Table 2). Numbers within the lines are the structural equation model estimates. R-squared values are in parentheses next to variable names and show the proportion of the variation explained by the model (endogenous variables only). Only direct relationships with P <‚ÄČ0.05 are shown. MAP = mean annual precipitation. dNBR = differenced Normalized Burn Ratio. Time between fires = time between the two most recent fires
