Northern Hemisphere forests changed drastically in the early Eocene with the diversification
of the oak family (Fagaceae). Cooling climates over the next 20 million years fostered the …

The oak flora of North America north of Mexico is both phylogenetically diverse and species-
rich, including 92 species placed in five sections of subgenus Quercus, the oak clade …

Oaks (Quercus L.) have long been suspected to hybridize in nature, and widespread genetic
exchange between morphologically defined species is well documented in two-to six …

Abstract Red oaks (Quercus sect. Lobatae) are a taxonomic group of hardwood trees, which
occur in swamp forests, subtropical chaparral and savannahs from Columbia to Canada …

Owing to high rates of introgressive hybridization, the plastid genome is poorly suited to fine-
scale DNA barcoding and phylogenetic studies of the oak genus (Quercus, Fagaceae). At …

The emergence of next generation sequencing has increased by several orders of
magnitude the amount of data available for phylogenetics. Reduced representation …

A long‐term debate in evolutionary biology is the extent to which reproductive isolation is a
necessary element of speciation. Hybridizing plants in general are cited as evidence against …

Introgression from one species in a specific environment to another may facilitate
colonization of the environment by the recipient species. However, such environment …

Aim We examined range‐wide genetic variation in a widespread white oak species in
western North America to determine phylogeographic patterns (including possible latitudinal …

Background Hybridization and introgression are common phenomena among oak species.
These processes can be beneficial by introducing favorable genetic variants across species …
