Fig. 4

a Trade-off between community-weighted means of stomatal density and length across 28 forest sites and 29 grassland sites. b Trade-off between stomatal density and length across grasses (with dumbbell shaped guard cells) and non-grass (with kidney-bean shaped guard cells) species. All stomatal traits are log-transformed. Ordinary least squares regression was used to explore relationship between stomatal density and length. The solid lines depict significant linear regressions, and the gray shading indicates the 95% confidence intervals. The differences in regression slopes and intercepts were assessed using analysis of covariance (ANCOVA). The p-value of <0.05 signifies significant differences in the slopes and intercepts of the linear regression between stomatal density and length. Source data are provided as a Source Data file.
