Rhexia Raw Data, Cleaned Data, and ENMs

This dataset contains the inputs and outputs associated with envriomental niche modelling (ENM) analyses conducted for Rhexia. The files are organized into several components, detailed below, and are provided to support reproducibility and further research on ecological modelling and biogeographic analyses. 1. Raw Occurrence Records Format: CSV Contents: Original species occurrence records obtained from GBIF and iDigBio. These records include coordinates, taxonomic information, and associated metadata. No filtering or cleaning was applied beyond the initial data download. 2. Cleaned Occurrence Records Format: CSV Contents: Occurrence records retained after data cleaning and spatial filtering. Records were examined for coordinate validity, spatial precision, and duplication, and further filtered to reduce sampling bias where applicable (e.g. spatial thinning). These data represent the final presence points used in model calibration and evaluation. 3. Pearson Correlation Matrices for Environmental Layers Format: CSV Contents: Pairwise Pearson correlation coefficients calculated among environmental predictor variables. 4. Current ENM Projections Format: GeoTIFF (.tif) Contents: Raster projections representing current habitat suitability for the species, as estimated by ENMs calibrated using present-day environmental variables. The GeoTIFF files contain continuous values indicating relative suitability across the modelled region. 5. Future ENM Projections Format: GeoTIFF (.tif) Contents: Raster projections of potential future habitat suitability under various climate change scenarios and time periods. Each file corresponds to a specific climate model, scenario (e.g. SSP1-2.6, SSP5-8.5), and time slice (e.g. 2041–2060, 2081–2100) for each Rhexia species. These projections were generated using the same modelling approach as for current conditions but applying future environmental layers.
