  bibo_abstract:
  - 'This paper analyses the conditions for local adaptation in a metapopulation with
    infinitely many islands under a model of hard selection, where population size
    depends on local fitness. Each island belongs to one of two distinct ecological
    niches or habitats. Fitness is influenced by an additive trait which is under
    habitat‐dependent directional selection. Our analysis is based on the diffusion
    approximation and accounts for both genetic drift and demographic stochasticity.
    By neglecting linkage disequilibria, it yields the joint distribution of allele
    frequencies and population size on each island. We find that under hard selection,
    the conditions for local adaptation in a rare habitat are more restrictive for
    more polygenic traits: even moderate migration load per locus at very many loci
    is sufficient for population sizes to decline. This further reduces the efficacy
    of selection at individual loci due to increased drift and because smaller populations
    are more prone to swamping due to migration, causing a positive feedback between
    increasing maladaptation and declining population sizes. Our analysis also highlights
    the importance of demographic stochasticity, which exacerbates the decline in
    numbers of maladapted populations, leading to population collapse in the rare
    habitat at significantly lower migration than predicted by deterministic arguments.@eng'
