| Sumario: | Description of the data and file structure The data contains two compressed folders: Folder Code: The R code used for the statistical analyses includes: "1.EDMs.R" for replicating distribution models of habitat types across Europe, and the associated maps and figures "2.BRTs.R" for replicating models of species richness using Boosted Regression Trees with a spatial autocovariate "3.GDMs" for replicating models of species composition using Generalized Dissimilarity models "figures.R" for replicating the figures created from BRTs and GDMs Folder Data: The data used for conducting the analyses includes: "Bio01.tif", "Bio02.tif", "Bio10.tif", "Bio12.tif" and "ph.tif": geo.tif files to upload the spatial predictors for the whole of Europe, where: Bio01 = annual mean temperature (in ºC); Bio02 = Mean Diurnal Range or thermal range (in ºC); Bio10 = summer mean temperature (in ºC); Bio12 = annual precipitation (in mm * 1000); pH: water pH spatial model "contrib_effect.xlsx" summarizes the relative importance (in %) of predictors in the BRTs (needed to create the figures), where: The rows show the relative importance (from 0 to 100) of predictors (pH, spatial autocovariate, plot area, water table depth, and bioclimatic variables as explained above. The columns show the habitat EUNIS types (Q22, etc.) and the models for vascular plants (v) and bryophytes (bry). Columns ending in "e" reflect the interpretation of effects (positive or negative) from the response curves obtained from the models (shown in the Supplementary Material). "data.filtered.RData" includes all the occurrences used for computed Ecosystem Distribution Models, including: name: EUNIS habitat types X,Y: geographic coordinates in ETRS89 (UTM 30N) Response: internal value to indicate the occurrence "fens3.RData" and "fens3.filtered.RData" contain plot species richness and additional data necessary for conducting the BRT models: ID: database identification (unique values) eunis: EUNIS type vas: number of vascular plants recorded in the plot bry: number of bryophytes recorded in the plot bio1,bio2,bio10 and bio12: bioclimatic variables as described above lat/long: geographic coordinates in decimal degrees area: plot area (in square meters) pH and wtd: water pH and water table depth (in cm) calculated for each plot "mosses.RData" and "vascular.RData" contain the compositional matrices data for bryophytes and vascular plants, respectively, where: siteCol is the unique ID for each plot, as required in the gdm R package eunis indicates the habitat type x,y include the geographic coordinates in ETRS89 (UTM 30N) sp1,sp2, etc. correspond to the cover values (in %) of all species sampled in each plot |
