Relationships between Neu and genomic attributes in nonphylogenetic (OLS) and phylogenetic (PGLS, RegOU) models.

Log10-transformed dependent variables were regressed on log10(Neu). Phylogenetic models used arbitrary branch lengths of 1.0 (see Materials and Methods). Note that r2 values are not comparable across OLS, PGLS, and RegOU models. Asterisks indicate RegOU models with significantly better fit than OLS models, based on ln likelihood ratio tests (see Results); b = regression slope; significant P-values are in bold.†Lynch & Conery [7] reported r2 = 0.659; the discrepancy apparently arises because their analysis used 30 species, only 29 of which were reported in their online supplement.
