Results from Fu’s Fs test and calculations of the exponential growth parameter g for Zonotrichia capensis lineages A, B and C (number of sequences used in each case indicated in parenthesis). Fu’s Fs test was performed on mitochondrial loci from the CR dataset, the combined mitochondrial data and for inferred haplotypes from nuclear markers. Statistically significant p values (< 0.05) are indicated in bold. For g, statistical significance was assessed through confidence intervals (see text for details).

*99% confidence interval does not include 0.

ns, not statistically significant (95% confidence interval includes 0).
