Fig. 3: Relationship between species age and range size across taxonomic scales.
From: Evolutionary age correlates with range size across plants and animals
A Overall relationship from a random effects (RE) model at the three taxonomic scales. B Forest plot of the species age-range size relationship for seven broad taxonomic groups, including the overall effect from the RE model. C Relationship at the order scale, where each tip in the phylogeny represents an order. D Relationship at the family scale, where each tip represents a family. We reconstructed the phylogenetic trees in TimeTree94 by choosing a representative species for each order or family (Supplementary Data 2). In the circular phylogenies, outer arc colours indicate the effect size (Z-score) and inner arc colours represent significance (p < 0.05). Icons and asterisks indicate significant relationships for broad taxonomic groups and orders (see Supplementary Fig. 4 for an extended figure). CI Confidence Interval. See detailed information in Supplementary Data 1 for background data. For display purposes, seven Z-scores below −2 or above 2 at the family scale were set to (-) 2. All statistical tests were two-sided, and p-values were not adjusted for multiple comparisons, as the random effect model accounted for heterogeneity within the meta-analysis.
