Discovering the extent of genetic differentiation between closely related taxa facilitates decisions regarding species protection under the Endangered Species Act. Here, we analyze genotype data to explore the relatedness of two buckwheat species: Eriogonum soredium Reveal- a narrow endemic under consideration for protection, and a widespread close relative, Eriogonum shockleyi S. Watson. Eriogonum soredium grows only on Ordovician limestone outcroppings in west central Utah, whereas the range of E. shockleyi is broad, spanning the western United States from Colorado to California, and Idaho to Arizona. Eriogonum shockleyi is suspected of hybridizing with other buckwheats throughout this range. We detected higher …

Premise of the study: Until recently, most phylogenetic studies of ferns were based on chloroplast genes. Evolutionary inferences based on these data can be incomplete because the characters are from a single linkage group and are uniparentally inherited. These limitations are particularly acute in studies of hybridization, which is prevalent in ferns; fern hybrids are common and ferns are able to hybridize across highly diverged lineages, up to 60 million years since divergence in one documented case. However, it not yet clear what effect such hybridization has on fern evolution, in part due to a paucity of available biparentally inherited …
