GFB1 Science Response to eLetters Figure&Rscript

Estimated BPR curve (with 95% confidence interval bands), using an ordinary least squares (OLS) model, based on the three grassland biomes (i.e. Montane Grasslands and Shrublands, Flooded Grasslands and Savannas, and Temperate Grasslands, Savannas and Shrublands). We converted species richness (S) to relative species richness (S_hat): S_hat = S *100 / 271.<br>R script for generating this graph is attached.

基于三类草原生物群系（即山地草原与灌丛（Montane Grasslands and Shrublands）、淹水草原与稀树草原（Flooded Grasslands and Savannas），以及温带草原、稀树草原与灌丛（Temperate Grasslands, Savannas and Shrublands）），采用普通最小二乘法（ordinary least squares, OLS）模型得到的估计BPR曲线（附带95%置信区间带）。
我们将物种丰富度（species richness，S）转换为相对物种丰富度（relative species richness，S_hat），转换公式为：S_hat = S × 100 / 271。
