Global phenotypic trait divergence (Pst), and analogous measures based on 18 microsatellite DNA loci (Fst), for paired-comparisons of lake trout among water depth strata. The horizontal error bars indicate 95Â % confidence intervals for the Fst (top bar) and Pst (all other bars) estimates. Combined effects of natural selection and random drift determine the Pst estimates, whereas the Fst estimates are determined by drift processes. Lower confidence limits of Pst estimates that fall to the left- and right-hand sides of the dashed vertical line (upper confidence limit of Fst) indicate the effect of drift and selection, respectively, on phenotypic trait divergence. Horizontal bars shaded in grey highlight phenotypic traits that putatively exceed neutral expectations based on Fst
