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

The distribution of fitness effects (DFE) of new mutations is a fundamental entity in genetics
that has implications ranging from the genetic basis of complex disease to the stability of the …

Small populations are predicted to have reduced capacity to adapt to environmental change
for two reasons. First, population genetic models indicate that genetic variation and potential …

Although invasive plant species often have a hybrid ancestry, unambiguous evidence that
hybridization has stimulated the evolution of invasive behaviors has been difficult to come …

Our understanding of homoploid hybrid speciation has advanced substantially since this
mechanism of species formation was codified 50 years ago. Early theory and research …

The distribution of effect sizes of genes underlying adaptation is unknown. Are suites of traits
that diverged under natural selection controlled by a few pleiotropic genes of large effect …

Phenotypic variation between individuals of a species is often under quantitative genetic
control. Genomic analysis of gene expression polymorphisms between individuals is rapidly …

Genomic approaches have accelerated the study of the quantitative genetics that underlie
phenotypic variation. These approaches associate genome-scale analyses such as …

Flowering time and water‐use efficiency (WUE) are two ecological traits that are important
for plant drought response. To understand the evolutionary significance of natural genetic …

Scientific inquiries in fields ranging from ecology to plant breeding assess phenotypic
variation within a plant species either to explain its presence or utilize its consequences …
