This table summarizes information on dataset numbers, response variable(s), study system (elevation gradient, warming experiment, or combined data), number of observations, taxa, plots, aspect, site, and location of the primary data, the final published data, and the code for extracting and cleaning data from the primary data. *the number of sampling plots within the elevation gradient and/or warming experiment from which measurements are taken, with the exception of dataset vi, where separate transects were set up at the relevant sites and aspects to avoid destructive sampling of plots. ^arefers to the number of plots along these additional transects.
