Fig. 2: Scaled and centred regression coefficients of final model variables.

Scaled and centred regression coefficients for all variables found in the final model. Variables have been ranked by absolute magnitude of regression coefficient. Wings are standard errors and bars represent the 95% confidence intervals estimated via a bootstrapping analysis. Bars are coloured and numbered according to variable group: a yellow indicating ENSO-associated climate anomalies variables, b red denotes background climate variables and c blue represents soil characteristics.
