Description
Data for Nature manuscript titled
“Environmental drivers of increased ecosystem respiration in a warming tundra”
Corresponding author Dr. Sybryn Maes – sybryn.maes@gmail.com
Github contains all R scripts on https://github.com/mjalava/tundraflux
Part A. Meta-analysis
The bold names refer to scripts (see the Github repository https://github.com/mjalava/tundraflux) and names in italics refer to files in this repository
df_0
-Study design Figure 1 and Extended Fig. 1 from main text
df_1a
-Effect size calculations of response (ER)
-Links to df_1.csv file with raw flux and environmental data
-Only the experiments that state ‘Open Access’ in the excel file Authors_Datasets (sheet 2). For experiments stating ‘Available Upon Request’, you need to contact the authors for the -raw flux data.
df_1b
-Effect size calculations of environmental drivers
-Links to df_1.csv file with raw flux data data (see above) and Dataset_ID.csv (this file includes all dataset IDs to merge the drivers into one dataframe)
df_2a-f
-Meta-analysis (2a) and meta-regression models (2b-f) (ER, N=136)
-Links to df_2.csv file with effect size data and context-dependencies and Forestplot_horiz_weights_fig.csv (this file includes the mean pooled Hedges SMD as well as the individual dataset Hedges SMD to plot figure 2)
-Contains code for Figs. 2-4 and Extended Figs 2-3
df_3
-Meta-regression for experimental warming duration
-Contains code for Fig. 5
df_4a
-Effect size calculations of autotrophic-heterotrophic respiration partitioning (Ra, Rh, N=9)
-Links to df_3.csv file with raw partitioning data of subset experiments (output file df_4.csv)
df_4b
-Sub-meta-analysis models (ER, Ra, Rh)
-Links to df_4.csv (input file)
NOTES
· All additional input files for the meta-analysis R-scripts are included within the folders.
· ER, Ra, Rh = ecosystem, autotrophic, and heterotrophic respiration
· N = sample size (number of datasets)
Part B. Upscaling results
For upscaling, the input data is described in the code files (see the Github repository) and the accompanying Readme.txt.
percentageChangeResp_tundraAlpine.tif: modelled change in respiration
baseResp_tundraAlpine.tif: baseline respiration (calculated from the data from literature)
modResp_tundraAlpine.tif: modelled respiration after warming (our calculations: (percentageChangeResp_tundraAlpine+1) * baseResp_tundraAlpine)
changeResp_tundraAlpine.tif: modResp-baseResp
standError_tundraAlpine.tif: standard error of modelled respiration (
standError_tundraAlpine_onlyDataUncertainty.tif: standard error of modelled respiration where only data uncertainty is taken into account
