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.
