Fig. 3From: Geographic range size and speciation in honeyeatersResults from phylogenetic generalised least squares regression models, testing the influence of variables on speciation rate (a) and traits and position on range size (b). Full model results are available in Additional file 2: Table S1. Bars indicate estimate and 95% confidence intervals. Note that for the PGLS results shown the predictor variables have been scaled so the effect sizes are comparableBack to article page
