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.

基于三类草原生物群系（即山地草原与灌丛、泛滥草原与稀树草原以及温带草原、稀树草原与灌丛），采用普通最小二乘法（ordinary least squares, OLS）模型生成的估计BPR曲线（含95%置信区间带）。本研究将物种丰富度（S）转换为相对物种丰富度（Ŝ），转换公式为：Ŝ = S × 100 / 271。生成该图表的R脚本已随附。
