Fig. 6: Species age-range size relationships when number of generations is used as a proxy for age.
From: Evolutionary age correlates with range size across plants and animals
Relationship between the number of generations, dispersal-related traits and species range size for birds (n = 7622 species) and terrestrial mammals (n = 4725 species). We considered ‘aerial dispersal’, ‘body size’, and ‘hand-wing index’ dispersal-related traits for each taxon model. Asterisks (*) denote significant relationships. N. Generations = number of generations; ‘x’ indicates an interactive effect. Points indicate the effect size (Z-score), with error bars showing the standard error (SE) for the Z-scores derived from linear mixed-effects models. Source data is provided as a Source Data file.
