abstract = {We study the evolution of specialization in a
spatially continuous (one-dimensional) environment
divided into two habitats; we use a general trade-off
function relating fitnesses in the two habitats and
illustrate our results with two classical trade-off
functions. We show that the population can either reach
an intermediate value of the trait and be moderately
adapted to both habitats (1 generalist), or split into
two locally adapted subpopulations (2 specialists). We
recover the qualitative results obtained with simpler
metapopulation models with island migration: the
evolutionary outcome depends on the concavity of the
trade-off, on the proportion of each habitat and on
migration. Our quantitative prediction on migration,
however, depends on isolation by distance. Our
spatially explicit model may thus be particularly
useful to describe the evolutionary dynamics of
specialization in, perhaps, more realistic ecological
scenarios.},
