Relationship between indel events per site per generation (u_idG_e) and effective population size (N_e) after phylogenetic correction. (A) Standardized phylogenetically independent contrasts performed using Compare (Martins 2004), and the PDAP module in Mesquite (Garland et al. 1993), with branch lengths of 1.0. The regression equation of the contrasts through the origin is: u_idG_e = –0.60(0.07)N_e (r² = 0.83, P = 1.28 × 10⁻⁶, d.f. = 13), with SE in parentheses. (B) Phylogenetic tree showing the relationship between organisms.
