Warming and elevated CO2 intensify drought and recovery responses of grassland carbon allocation to soil respiration
收藏资源简介：
We provide data and the code for ecosystem CO<sub>2</sub> flux, soil respired CO<sub>2,</sub> and <sup>13</sup>CO<sub>2</sub>. The measurements were made under drought, elevated CO2, and warming treatment in grassland during summer 2017. The file 'Ecosystemfluxes.csv' contains data of ecosystem fluxes (Gross primary productivity; Ecosystem respiration; Net ecosystem productivity). The file 'C13remaining.csv' contains data of excess <sup>13</sup>C in the plant, soil, and soil respiration 8 days after <sup>13</sup>CO<sub>2</sub> pulse labeling. The file 'dynamics.csv' contains data of soil respired CO2, 13CO2, soil water content, soil temperature and PAR. The R file 'Ecosystem_Fluxes.R' explains and plots the data from 'Ecosystemfluxes.csv' The R file 'C13_remaining.R' explains and plots the data from 'C13remaining.csv'. The R file 'Time_dynamics.R' explains and plots the data from 'dynamics.csv'. In addition, this R file also provides the script for time series regression analysis between response variables (soil respired CO<sub>2</sub> and soil respired <sup>13</sup>CO<sub>2</sub>) and environmental drivers (soil water content, soil temperature, and PAR).
