Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

Two major developments have made it possible to use examples of ecological radiations as
model systems to understand evolution and ecology. First, the integration of quantitative …

Genetic correlations between traits can concentrate genetic variance into fewer phenotypic
dimensions that can bias evolutionary trajectories along the axis of greatest genetic variance …

Identifying the genetic architecture underlying adaptive traits is exceptionally challenging in
natural populations. This is because associations between traits not only mask the targets of …

The occurrence of parallel speciation strongly implies the action of natural selection.
However, it is unclear how general a phenomena parallel speciation is since it was only …

New species arise through the evolution of reproductive barriers between formerly
interbreeding lineages. Yet, comprehensive assessments of potential reproductive barriers …

Polyploidy is pervasive in angiosperm evolution and plays important roles in adaptation and
speciation. However, polyploid groups are understudied due to complex sequence …

Background Natural hybridization can influence the adaptive response to selection and
accelerate species diversification. Understanding the composition and structure of hybrid …

Understanding the genetic architecture of complex traits is a major objective in biology. The
standard approach for doing so is genome-wide association studies (GWAS), which aim to …

The independent and repeated adaptation of populations to similar environments often
results in the evolution of similar forms. This phenomenon creates a strong correlation …
