Species Richness Gradients Vary Across Phylogenetic Scales
Global Ecology and Biogeography, Volume 34, Issue 12, December 2025.ABSTRACT Aim To determine how species richness gradients—commonly considered universal—vary across the phylogenetic hierarchy of birds and mammals, and to uncover how clade age and size predetermine the gradients. Location Global. Time Period Last 120 million years. Taxa Studied Birds and mammals (~15,000 species).
