Gene flow is a fundamental evolutionary force in adaptation that is especially important to
understand as humans are rapidly changing both the natural environment and natural levels …

Divergent natural selection, adaptive divergence and gene flow may interact in a number of
ways. Recent studies have focused on the balance between selection and gene flow in …

The genetic swamping hypothesis proposes that gene flow from central to peripheral
populations inhibits local adaptation and is one of the most widely recognized explanations …

Gene flow among populations can enhance local adaptation if it introduces new genetic
variants available for selection, but strong gene flow can also stall adaptation by swamping …

Many ecologically important traits have a complex genetic basis, with the potential for
mutations at many different genes to shape the phenotype. Even so, studies of local …

In spatially heterogeneous environments, the processes of gene flow, mutation, and sexual
reproduction generate local genetic variation and thus provide material for local adaptation …

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

It is increasingly important to improve our understanding of the genetic basis of local
adaptation because of its relevance to climate change, crop and animal production, and …

Genomic scans of multiple populations often reveal marker loci with greatly increased
differentiation between populations. Often this differentiation coincides in space with …

Why do species not adapt to ever-wider ranges of conditions, gradually expanding their
ecological niche and geographic range? Gene flow across environments has two conflicting …
