Local environmental variables are key drivers of ant taxonomic and functional beta-diversity in a Mediterranean dryland

Abstract The decomposition of beta-diversity (β-diversity) into its replacement (βrepl) and richness (βrich) components in combination with a taxonomic and functional approach, may help to identify processes driving community composition along environmental gradients. We aimed to understand which ab...
