Relationship of (a) species richness and (b) total vegetation cover with altitude along an elevational gradient in the Alborz Mountains (Iran). Vegetation sampling was conducted in 10 m × 10 m square plots. The black points represent observed data, while the blue dashed lines represent the loess smoother. The grey areas show the confidence interval around the fitted line.
