Sown species composition

This file contains information on which species were sown into each of 27 experimental plots (2x2 m). The first column (‘plot.id’) gives the ID of the plot, linking the table to the other tables. All other columns contain presence/absence information of the plant species. 1, species sown; 0, species not sown

(a) Aboveground biomass, (b) belowground biomass, (c) floral abundance, (d) vegetation height, (e) cover, and (f) soil respiration rate (means ± 95% confidence intervals) of mesocosm communities in the climate chambers of an ecotron facility. Data points are light-colored circles (n = 4).</p

Effects of forb proportion, precipitation and climate change scenario on grassland multifunctionality.

Two approaches to multifunctionality (MF) were calculated using eight indicator variables, including either aboveground biomass (a, b) or floral density (c, d) of mesocosm communities in the climate chambers of an ecotron facility. Averaged standardized values of the individual indicators contributed to averaged multifunctionality, whereas for the selected threshold, each function indicator exceeding 70% of the standardized maximum contributed to multifunctionality. Shown are means ± 95% confidence intervals. Data points are light-colored circles (n = 4).</p
