Divergent selection applied to one or more traits drives local adaptation and may lead to
ecological speciation. Divergent selection on many traits might be termed “multidimensional” …

Environmental heterogeneity is considered a general explanation for phenotypic
diversification, particularly when heterogeneity causes populations to diverge via local …

Divergent selection across the landscape can favor the evolution of local adaptation in
populations experiencing contrasting conditions. Local adaptation is widely observed in a …

Local adaptation is a fundamental evolutionary process generating biological diversity and
potentially enabling ecological speciation. Divergent selection underlies the evolution of …

Adaptation often proceeds from standing variation, and natural selection acting on pairs of
populations is a quantitative continuum ranging from parallel to divergent. Yet, it is unclear …

Evolutionary biology has struggled to explain the coexistence of two basic observations:
Genetic variation is found in almost all traits in the presence of strong natural and sexual …

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 …

Observations about the number, frequency, effect size, and genomic distribution of alleles
associated with complex traits must be interpreted in light of evolutionary process. These …

Although models of evolution usually assume that the strength of selection on a trait and the
expression of genetic variation in that trait are independent, whenever the same ecological …

Trait diversity–the substrate for natural selection–is necessary for adaptation through
selection, particularly in populations faced with environmental changes that diminish …
