Description of the data and file structure

This repository contains three datasets in Microsoft Excel format. The first file (Data 01.xlsx) contains three spreadsheets that provide the values of temperature, rainfall, and volumetric soil water content measured in controls that remained under the current climate and plots in which mid-century climate change conditions were induced (CCS plots). The second file (Data 02.xlsx) contains a single spreadsheet that provides the richness of communities when seeded at the beginning of the experiment (So), their richness when harvested at the end of the experiment (Sf), their aboveground productivity (Pa), their belowground productivity (Pb), and their net primary production (NPP = Pb + Pa). The third file (Data 03.xlsx) contains eleven spreadsheets that provide the shoot, root, and total biomass of each plant species within the communities in which it participated.

Files and variables

File: Data_01.xlsx

Description: Values of temperature, rainfall, and volumetric soil water content measured in controls that remained under the current climate and plots in which mid-century climate change conditions were induced (CCS plots).

Variables

• Experimental unit: number of the experimental unit in which variables were measured.
• Temperature in Controls (°C): average temperature recorded with dataloggers in controls that remained under the current climate (in °C).
• Temperature in CCS plots (°C): average temperature recorded with dataloggers in plots where mid-century climate change conditions were induced (in °C).
• Rainfall in Controls (mm): accumulated rainfall recorded with rain gauges in controls that remained under the current climate (in mm).
• Rainfall in CCS plots (mm): accumulated rainfall recorded with rain gauges in plots where mid-century climate change conditions were induced (in mm).
• Volumetric soil water content in Controls (%): average volumetric soil water content measured with time-domain reflectometer in controls that remained under the current climate (in % of water in the soil).
• Volumetric soil water content in CCS plots (%): average volumetric soil water content measured with time-domain reflectometer in in plots where mid-century climate change conditions were induced (in % of water in the soil).

File: Data_02.xlsx

Description: Species diversity values and biomass values of plant communities developed in controls that remained under the current climate and plots in which mid-century climate change conditions were induced (CCS plots).

Variables

• Experimental unit: number of the experimental community in which variables were measured.
• So: richness of communities when seeded at the beginning of the experiment.
• Sf: richness of communities when harvested at the end of the experiment.
• Pb: belowground productivity of communities when harvested at the end of the experiment (in mg).
• Pa: aboveground productivity of communities when harvested at the end of the experiment (in mg).
• NPP: net primary production of communities when harvested at the end of the experiment (in mg).

File: Data_03.xlsx

Description: Biomass of each plant species within the communities in which it participated, both in controls that remained under the current climate and plots in which mid-century climate change conditions were induced (CCS plots).

Each sheet contains data for one species. Species/sheet names are:

• Bidens pilosa
• Bothriochloa laguroides
• Bouteloua curtipendula
• Bouteloua gracilis
• Chloris virgata
• Eriophyllum confertiflorum
• Salvia tiliifolia
• Sanvitalia procumbens
• Sphaeralcea angustifolia
• Verbesina encelioides
• Xanthisma gracile

Variables

• Shoot biomass: aboveground biomass of the species within the corresponding community (in mg).
• Root biomass: belowground biomass of the species within the corresponding community (in mg).
• Species biomass: total biomass of the species within the corresponding community (in mg).
