Fig. 4From: Elevational patterns of bird species richness on the eastern slope of Mt. Gongga, Sichuan Province, ChinaElevational patterns of interpolated species richness (blue solid line). a Total species; b Small-ranged species; c Large-ranged species. Predicted species richness (gray solid lines) under the assumption of random range placement (MDE, the mid-domain effect); gray dotted lines indicate upper and lower 95% confidence interval simulation limitsBack to article page
