Ancestral population size predicts descendant GC3. Reconstructed population sizes for internal branches with two descendant lineages are positively correlated with descendant GC3 content. Population size was inferred from relationships between ancestral generation time, split dates, and coalescent branch lengths computed from the degree of gene tree discordance. Note that the population sizes here are expected to be overestimates, as age of first female sexual maturity was used as a proxy for generation time (see Materials and Methods), and are intended to be interpreted in terms of rank order.
