(X → Z: from L. catesbeianus to endemic species; Z → X: from endemic species to L. catesbeianus) D means niche overlap (Schoener’s D) and P means statistical significance. Endemic species in Group 1 showed climate similarity with L. catesbeianus in two ways; in Group 2 only L. catesbeianus was significant, in Group 3 only endemic species obtain significant differences and Group 4 not show significant differences in either way.
