Many populations are composed of a mixture of individuals that reproduce at different times,
and these times are often heritable. Under these conditions, gene flow should be limited …

The selective mechanisms for maintaining polymorphism in natural populations has been
the subject of theory, experiments, and review over the past half century. Advances in …

Habitat fragmentation, an important element of current global change, has profound
repercussions on population and species extinction. Landscape fragmentation reduces …

Gene flow among populations is typically thought to be antagonistic to population
differentiation and local adaptation. However, this assumes that dispersing individuals …

We derive a comprehensive overview of specialization evolution based on analytical results
and numerical illustrations. We study the separate and joint evolution of two critical facets of …

It is widely recognized that ecological dynamics influence evolutionary dynamics, and
conversely that evolutionary changes alter ecological processes. Because fragmentation …

It can be challenging for organisms to achieve a good match between their phenotypic
characteristics and environmental requirements that vary in space and time. The evolution of …

In species undergoing range expansion, newly established populations are often more
dispersive than older populations. Because dispersal phenotypes are complex and often …

Adaptive divergence between adjoining populations reflects a balance between the
diversifying effect of divergent selection and the potentially homogenizing effect of gene …

Dispersal, the tendency for organisms to reproduce away from their parents, influences
many evolutionary and ecological processes, from speciation and extinction events, to the …
