- ... Pinus subsection Cembroides comprises approximately 15 taxa distributed from the southwestern United States to south central Mexico. Despite previous phylogenetic studies based on morphology, nuclear ribosomal DNA, and plastid DNA, we still lack a robust phylogenetic hypothesis and clear delimitation for the closely-related species within the group. We studied the evolutionary relationships within ...

- ... The major aim of this paper was to investigate temporal diversification within Symphoricarpos (Caprifoliaceae, Dipsacales). We used recently published molecular sequences, along with fossil data, to examine when Symphoricarpos may have arrived in the New World and if current distributional patterns can be explained by data based on biogeographic, climatological, and geological events. We simultane ...
