Tests of neutral equilibrium assumptions in Agelaius phoeniceus and A. tricolor.

Values of Tajima's D[36] are accompanied by 95% confidence intervals of the statistic based on the the expected β distribution under the infinite sites model (table 2 in [36]), and as assessed for data simulated under the best–fit finite-sites model of sequence evolution (FS; see text). Values of Misawa and Tajima's (modified; see Appendices 2 and 3) and of Fu's Fs statistic [37] are also given, along with 95% CIs (or 5th percentiles for FS, which is evaluated one-tailed) estimated by simulation as for D. Significance of D, Ds*+, and Fs given either the β distribution or coalescent simulations under the infinite sites model (Fs only) is shown by asterisks (*PP
