Appendix B. Structural equation model diagram for species richness of habitat specialist butterflies when using only the main host plants of habitat specialists.

FIG. B1. Structural equation model for the influence of different factors (GDD5, TJAN, AET/PET, host plant richness, habitat diversity and COAST) on the species richness of habitat specialist butterflies. Host plant richness was calculated including only main host-plants used by habitat specialist butterflies. Significant standardized path coefficients (*** P < 0.001). Proportional weighted arrows represent strength of associations between variables.
