Data for: "Land-use intensity influences European tetrapod food-webs"

These .Rdata files enable to reproduce results from our article " Signatures of land use intensity on european tetrapod food-web architectures" along with the R code provided at: https://github.com/ChrisBotella/foodwebs_vs_land_use

- raw_data : Raw data including GBIF and iNaturalist occurrences and IUCN enveloppes used to select sites and generate species presence/absence. We provide this file for transparency and reproducibility of our methodology.

- preprocessed_data: preprocessed data (obtained from raw_data) used to generate our article Figures along with the next file.

- TrophicNetworksList : .Rdata containing a list of igraph objects, each igraph is a foodweb associated to a site identify by the list element name. 

- MultiRegMatrices: .Rdata containing especially the pre-computed matrix Y of cells (rows) by food web metrics (columns) and the covariate design matrix X (for the linear regressions) in order to facilitate and accelerate the reproduction of the analyses.
