Data and script of the MS "Shrub canopies preserve climatic niche disparity among recruit species in Mediterranean drylands"

README – Supplementary Datasets and script of the MS "Shrub canopies preserve climatic niche disparity among recruit species in Mediterranean drylands" File: data.csv Data: Plot-level composition and climatic niche dataset This dataset contains climatic niche metrics, community composition for plots sampled under different treatments (shrub vs. open) in our study area (South and Eastern Iberian Peninsula). Each row represents a unique plot, and columns include taxonomic information, climatic niche distances and other composition data. See Material and methods for further information of the sampling and methodology. Columns description ID: Unique record identifier Shrub species: Species name of the shrub (canopy) Richness: Number of species in the plot Shanon: Shannon diversity index of the plot Community: Community identifier (Study area) Treatment: Shrub vs. open area (gap) Pair: Pairing identifier for experimental design (Each shrub has its respective gap) OC_X, OC_Y: Coordinates of the Observed Climate of the community projected in the PCA describing the climatic space ID2: Pair identifier cic_x_c, cic_y_c: Coordinates of the Community inferred Climate based on niche centroids of the plot recruits. Cd: Climatic disequilibrium, i.e. the Climatic distance between cic / and the OC Niche_disparity: Climatic niche disparity metric at plot level Weighted_SD: Weighted standard deviation of climatic distances at plot level Cd_x, cd_y: Climatic disequilibriums decomposed along the two main PCA axis CV_RAD: Coefficient of variation of photosynthetically active radiation (PAR) measured in radians. File: taxa.csv Data: list of taxonomic species This dataset contains all the identified species recorded for the phylogenetic study. It includes three columns, each providing taxonomic information: the species name, the genus, and the family to which each species belongs. Columns description Species: scientific name of the species Genus: Genus to which the species belongs Family: Family to which the species belongs File: Plot_recruits.csv Data: list of recruit species of each plot This dataset contains all the identified species recorded on the fieldwork. Each row corresponds to a unique combination of species and plot Columns description Plot: Plot identifier Shrub: Species of the Shrub (Canopy) Species: Species name of the recruit Cover: cover of the recruit species File: recruit_pca_centroids.csv Data: Climatic niche information of each recruit species This dataset contains climatic niche information for all recruit species identified during fieldwork. Each row corresponds to a unique combination of species and plot. The niche information is represented by the coordinates of species niche centroids along the first two principal components of climatic space. Columns description Plot: Plot identifier Shrub: Species name of the plot Shrub (Canopy) Species: Species name of the recruit Centroid_r1, Centroid_r2: Coordinates of the species niche centroids along the two main PCA axis.
