Climatic and geographic drivers of fern phylogenetic diversity and variability in Central Argentina

Abstract

This repository contains the datasets used to analyse spatial patterns of species richness, phylogenetic diversity, and phylogenetic variability of ferns in the mountains of Central Argentina (Córdoba Province). The files include: (i) the list of fern species incorporated into the phylogenetic framework, (ii) geographic and climatic variables associated with a 1-km² grid covering the study area, and (iii–iv) grid-cell estimates of phylogenetic diversity and phylogenetic species variability derived from the phylogenetic tree and reconstructed species distributions.

The phylogenetic framework is based on a dated, time-calibrated fern phylogeny, with missing taxa incorporated using a standardized phylogenetic insertion approach. Species distributions were reconstructed from compiled occurrence-based range data and overlaid onto the spatial grid to calculate phylogenetic metrics.
