abstract = {Understanding the conditions for the stable
coexistence of different alleles or species is a
central topic in theoretical evolution and ecology.
Different causes for stable polymorphism or species
coexistence have already been identified but they can
be grouped into a limited number of general processes.
This article is devoted to the presentation and
illustration of a new process, which we call 'habitat
boundary polymorphism', and which relies on two key
ingredients: habitat heterogeneity and distance-limited
dispersal. Under direct competition and with fixed
population densities, we show that this process allows
for the equilibrium coexistence of more than n types in
a n-habitat environment. Distance-limited dispersal
indeed creates local maladaptation at habitat edges,
which leaves room for the invasion of more generalist
alleles or species. This mechanism provides a generic
yet neglected process for the maintenance of
polymorphism or species coexistence.},
