Contains 4 folders:1. america_sin_islasShapefile of america, used to crop environmental layer (bioclimatic and PCs).2. environmental2.1 bio_10m_bil (folfer): Bioclimatic layers at 10 arcminutes
2.2 ntbox_envLayers -> CMIP5_rcp85_y50__bio_10 (folders): Bioclimatic layers at 10 arcminutes for representative concentration pathway 8.5 for the CCSM4 general circulation model.2.3 PCA_future:
A folder with the projected Principal Components (PCs) layers of the bioclimatic variables of WorldClim (without bio 8, 9, 18, and 19). The layers that were used to project the PCs were the ones for the representative concentration pathway 8.5 for the CCSM4 general circulation model available from (Hijmans et al. 2005a).
2.4 PCA_present:A folder withPrincipal Components (PCs) layers of the of the bioclimatic variables of WorldClim (without bio 8, 9, 18, and 19). It also has the scree plot of the variance explained variance by each component.
