Univariate regression model results referring to woody plants without any distinction of strata. Left: Relationships between independent variables and aboveground woody biomass (AWB). Right: Relationships between independent variables and aboveground woody biomass production (ABP). Each variable was standardized and their effect size (circles) was compared to determine differences in strength of predictor variables on AWB/ABP. The solid circles represent significant effects (p < 0.05). The hollow circles indicate relationships that are not significant (p > 0.05). The lines indicate standard errors
