a Effects of forest cover (%) at a 400-m scale and landscape heterogeneity (H’) at a 200-m scale on floral resource functional diversity (H’); black dots represent values above the surface and gray dots below. b Effects of forest cover (%) at a 2000-m scale on species richness. Black dots are the residuals, and lines are the predicted values based on generalized linear models. Dashed lines represent confidence intervals (R Core Team, 2013)
