Fig 8. Results of structural equation model (model1).

Grey boxes represent latent variables that are part of the conceptual model hypothesized in Fig 1. White boxed represent the variables measured in this study which serve as surrogates of latent variables. Arrows represent the paths or the hypothesized relationship between the latent variables based on climatic stability hypothesis. Numbers in parenthesis associated with paths between variables represent standardized coefficients of the relationship between them while numbers below the endogenous variables represent the variation explained by the exogenous variables.
