Linking environmental gradients, functional traits, and Phylogenetic structure in Meloidae (Coleoptera) assemblages of inner western Anatolia

This dataset contains species incidence records, environmental predictors, trait information, and R scripts used for the Hierarchical Modelling of Species Communities (HMSC) analysis of Meloidae (Coleoptera) assemblages in the Inner Western Anatolia region of Türkiye. The dataset includes three input files: (i) species_incidence.csv, a presence–absence matrix of Meloidae species across sampled sites, (ii) environment_filt.csv, a matrix of environmental predictors (bioclimatic, topographic, land-cover, and vegetation variables), and (iii) traits.csv, trait information including larval dispersal strategies (phoresy) and host type, as well as wing morphology. In addition, seven R scripts (HMSC_Script1–7.R) provide the complete workflow for data processing, model fitting, convergence assessment, prediction, and visualization.
