Figure 4
Results of full model migration matrix. We allowed all parameters to vary independently. We calculated migration direction and rates from: (A) 17 microsatellite loci and (B) mtDNA control region data. N e m and N f m = estimate for number of migrants/females per generation based on nuclear microsatellites and mtDNA, respectively. Θ = population size (4Neμ; see text). 95% confidence intervals for parameter values are in parentheses. Arrow thickness is proportionate to estimated levels of gene flow (thicker arrows indicate higher relative gene flow).
