An increasing number of studies using genetic data at the generic and species levels reveal
complex patterns of relationships among populations and species. Incomplete lineage …

Multispecies interbreeding networks, or syngameons, have been increasingly reported in
natural systems. However, the formation, structure, and maintenance of syngameons have …

The complex evolutionary history of the subtribe Physalinae is reflected in the poor
resolution of the relationships of Physalis and the physaloid genera. We hypothesize that …

Premise Accurate species delimitation is essential for evolutionary biology, conservation,
and biodiversity management. We studied species delimitation in North American pinyon …

Pinus subsection Cembroides comprises approximately 15 taxa distributed from the
southwestern United States to south central Mexico. Despite previous phylogenetic studies …

One of the major goals of systematics is to provide a synthesis of knowledge on the diversity
of a group of organisms, such as flowering plants. Biodiversity conservation and …

Abstract Background and Aims Pinyon pine hybridization is widely acknowledged, but the
frequency of and contributors to such interspecific mating remain largely unstudied. Pinus …

Reticulate evolution by hybridization is considered a common process sha** the evolution
of many plant species, however, reticulation could also be due to incomplete lineage sorting …

Mexico is home to the highest species diversity of pines: 46 species out of 113 reported
around the world. Within the great diversity of pines in Mexico, Pinus culminicola Andresen …

Genetic conservation is key to maintaining forests for the future; however, these face several
threats. Mexico is an example of the degradation of forest genetic resources during the past …
