Fig. 2: The empirical relationship between species age and range size significantly deviates from the null expectation.
From: Evolutionary age correlates with range size across plants and animals
The null scenario assumes no correlation between species age and range size, indicating an absence of phylogenetic signal for age. Frequency distribution of effect sizes (indicated by blue bars) from linear mixed-effect models based on 1000 randomizations of age across the phylogeny, for (A) all taxa combined and (B–H) separated for the seven broad taxonomic groups: B amphibians, C reef fishes, D birds, E reptiles, F palms, G terrestrial mammals, and H) marine mammals. The red line denotes the observed effect size of age on range size for the empirical data. Source data is provided as a Source Data file.
