  text: 'Populations living in a spatially and temporally changing environment can
    adapt to the changing optimum and/or migrate toward favorable habitats. Here we
    extend previous analyses with a static optimum to allow the environment to vary
    in time as well as in space. The model follows both population dynamics and the
    trait mean under stabilizing selection, and the outcomes can be understood by
    comparing the loads due to genetic variance, dispersal, and temporal change. With
    fixed genetic variance, we obtain two regimes: (1) adaptation that is uniform
    along the environmental gradient and that responds to the moving optimum as expected
    for panmictic populations and when the spatial gradient is sufficiently steep,
    and (2) a population with limited range that adapts more slowly than the environmental
    optimum changes in both time and space; the population therefore becomes locally
    extinct and migrates toward suitable habitat. We also use a population‐genetic
    model with many loci to allow genetic variance to evolve, and we show that the
    only solution now has uniform adaptation.'
