Species often include multiple ecotypes that are adapted to different environments.
However, it is unclear how ecotypes arise and how their distinctive combinations of adaptive …

The role of adaptation in the divergence of lineages has long been a central question in
evolutionary biology, and as multilocus sequence data sets have become available for a …

Measuring reproductive barriers between groups of organisms is an effective way to
determine the traits and mechanisms that impede gene flow. However, to understand the …

The genomics of local adaptation is an increasingly active field, providing insights into the
forces driving ecological speciation and the repeatability of evolution. Demography and …

• Premise of the study: The sunflower genus Helianthus has long been recognized as
economically significant, containing species of agricultural and horticultural importance …

The probability of parallel genetic evolution is a function of the strength of selection and
constraints imposed by genetic architecture. Inversions capture locally adapted alleles and …

PREMISE: Wild sunflowers harbor considerable genetic diversity and are a major resource
for improvement of the cultivated sunflower, Helianthus annuus. The Helianthus genus is …

Map** the chromosomal rearrangements between species can inform our understanding
of genome evolution, reproductive isolation, and speciation. Here, we present a novel …

Connecting broad‐scale patterns of genetic variation and population structure to genetic
diversity on a landscape is a key step towards understanding historical processes of …

The annual sunflowers (Helianthus sect. Helianthus) present a formidable challenge for
phylogenetic inference because of ancient hybrid speciation, recent introgression, and …
