Effective sizes and time to migration-drift equilibrium in geographically subdivided populations.

摘要: Abstract Many versions of the effective population size ( N e ) exist, and they are important in genetics order to quantify rates change various characteristics, such as inbreeding, heterozygosity, or allele frequencies. Traditionally, was defined for single, isolated populations, but we have recently presented a mathematical framework subdivided populations. In this paper focus on diploid populations with geographic subdivision, present new theoretical results. We compare haploid inbreeding I novel expression variance V ), conclude that local is often much smaller than both , whenever exist. Global metapopulation, other hand, close larger . introduce size, additive genetic A which particular interest long term protection species. It quantifies rate at lost show closely related version Finally, measure population’s deviation from migration–drift equilibrium, apply it time takes reach equilibrium. Our findings importance understanding concept substructured many results applications conservation biology.
