MULTIFUNCTIONALITY DATASETS Datasets used in "Nitrogen availability and plant functional composition modify biodiversity-multifunctionality relationships" from Noémie A. Pichon, Seraina L. Cappelli, Tosca Mannall, Thu Zar Nwe, Norbert Hölzel, Valentin H. Klaus, Till Kleinebecker, Santiago Soliveres, Hugo Vincent and Eric Allan Initial manuscript can be found on bioRxiv: https://www.biorxiv.org/content/10.1101/2020.08.17.254086v1 This experiment manipulates in a full factorial design species richness (1, 4, 8 species), nitrogen enrichment (0, 100 kg ha-1 year-1), fugicide spraying (unsprayed, sprayed) and initial community composition in SLA (gradient in growth strategies). See methods for more info on the design. If you have further questions: noemie.pichon@wsl.ch These datasets can be used with code on GitHub: https://github.com/noemiepichon/multifunctionality To calculate multifunctionality, please use the code in GitHub "Megamodel github.R" To calculate species effect on functioning, please use the code in "Sp effect on function github.R" Attention: the functions were transformed before calculating multifunctionality. See methods. In the first dataset "All_BigData.txt", we put together the ten functions measured on each plot of the experiment, and each plot community metrics (SLA, richness etc). All_BigData.txt: Plot_Nr Block 1 to 4 Species_richness 1 to 20 Functional_composition F, M, S, for Fast, mixed or slow initial sown composition Nitrogen 0 or 1 Fungicide 0 or 1 Combination unique combination of species, growing once in control conditions, once with nitrogen, once with fungicide, once with both CWM_SLA Community specific leaf area calculated with monoculture SLA values and plot-specific abundances MPD_SLA_abundance Mean pairwise distance in specific leaf area calculated with monoculture SLA values and plot-specific abundances MPD_SLA_presence Mean pairwise distance in specific leaf area calculated with monoculture SLA values equally weighted Aboveground_biomass (will be sqrt trandformed) Herbivory (will be sqrt trandformed) Pathogens (no transformation needed) Soil_respiration (will be log trandformed) Plant_N_uptake (will be log trandformed) Plant_P_uptake (will be log trandformed) Belowground_biomass (will be log trandformed) BGlucosidase (will be sqrt trandformed) Phosphatase (will be log trandformed) Carbon_storage (will be sqrt+1 trandformed) The second dataset "Mean_SLA.txt" is the mean SLA per control monoculture, averaged over the years. Plot_Nr CWM_SLA Community specific leaf area calculated with monoculture SLA values and plot-specific abundances Species Abbreviation for species identity The last dataset "species_presence.txt" indicates if a species is present (1) or absent (0) of a plot.
