Main data and Code for: Climate influences how belowground traits regulate grassland biomass

This dataset contains plot-level observations of aboveground biomass, community-weighted mean (CWM) plant traits, trait coverage metrics, and environmental variables across grassland sites compiled from multiple ecological databases. All community-level belowground trait data was calculated based on community-level vegetation composition (quantified in % species coverage per plot, or in the case of "PolarData (Polar)" as species-specific biomass per plot) derived from the respective databases. All trait data derived from the UNDERPLOT database. Each row represents one plot in one year. The subset containing data from the Nutrient Network (NutNet) used in this study is published separately due to network data sharing policies (see related works below). In addition, this dataset is accompanied with the RCode used in Andraczek et al. "Climate influences how belowground traits regulate grassland biomass". See the readme for a description of the workflow and how the script is supposed to be used. Note that this script works with both the main dataset, and in addition, also the subset containing data from the Nutrient Network which is published separately in Zenodo (see related works below).
