Table D1. Power analysis of microsatellite data with POWSIM (Ryman, 2011, User’s manual of POWSIM, a computer program for assessing statistical power when testing for genetic homogeneity, Version 4.1). The test was conducted for all 32 populations used in other analyses (including 5 pooled populations in the native range) and 47 non-pooled native populations (with 1–30 individuals collected per site), respectively. Five levels of population differentiation (Fst = 0.001, 0.0025, 0.005, 0.01, 0.025) were pre-defined with effective population sizes Ne = 1000 and Ne = 10,000 and the simulation was replicated 1000 times. Fisher’s exact P values are shown. The results suggest that our data can effectively distinguish genetic differentiation corresponding to Fst ≥ 0.01, which provides sufficient power to address the broad-scale spatial genetic structure of P. canescens.
