Age-specific survivorship and fecundity shape genetic diversity in marine fishes.

ABSTRACT: Genetic diversity varies among species due to a range of eco-evolutionary processes that are not fully understood. The neutral theory predicts that the amount of variation in the genome sequence between different individuals of the same species should increase with its effective population size ( N e ). In real populations, multiple factors that modulate the variance in reproductive success among individuals cause N e to differ from the total number of individuals ( N ). Among these, age-specific mortality and fecundity rates are known to have a direct impact on the N e / N ratio. However, the extent to which vital rates account for differences in genetic diversity among species remains unknown. Here, we addressed this question by comparing genome-wide genetic diversity across 1
