Predicting bird functional diversity across North America: An assembly rules approach integrating ecological processes

This dataset contains all input data and R scripts used to reproduce the analyses in Escobar et al., which evaluate how different ecological assembly rules (environmental filtering, competition, and abundance–suitability relationships) predict observed functional diversity in bird communities across North America.The dataset includes standardized macroecological model (MEM) inputs, species suitability matrices, trait-based functional diversity data, and simulation scripts for three community assembly scenarios. Functional diversity metrics—functional dispersion (FDis), functional richness (FRic), and Rao’s quadratic entropy (RaoQ)—were computed for both observed and simulated assemblages using four PCoA trait axes derived from ten morphological and ecological traits of 102 Emberizoidea species.
