The Use of Geological and Paleontological Evidence in Evaluating Plant Phylogeographic Hypotheses in the Northern Hemisphere Tertiary
Phylogeography posits that the sequence of speciation events within a clade should parallel the geographic migration and isolation of members of the clade through time. The primary historicalExpand

Dated molecular phylogenies indicate a Miocene origin for Arabidopsis thaliana
Dated molecular phylogenies are the basis for understanding species diversity and for linking changes in rates of diversification with historical events such as restructuring in developmentalExpand

Rosid radiation and the rapid rise of angiosperm-dominated forests
The rosid clade (70,000 species) contains more than one-fourth of all angiosperm species and includes most lineages of extant temperate and tropical forest trees. Despite progress in elucidatingExpand

Timing the eastern Asian-eastern North American floristic disjunction: molecular clock corroborates paleontological estimates.
Sequence data of the chloroplast gene rbcL were used to estimate the time of the well-known eastern Asian-eastern North American floristic disjunction. Sequence divergence of rbcL was examined for 22Expand

The Oligocene Bridge Creek Flora of the John Day Formation, Oregon
This systematic revision of the Bridge Creek flora is based on large collections of megafossil specimens from the John Day and Crooked River basins. The flora was found to be more diverse thanExpand

Eastern Asian endemic seed plant genera and their paleogeographic history throughout the Northern Hemisphere
We review the fossil history of seed plant genera that are now endemic to eastern Asia. Although the majority of eastern Asian endemic genera have no known fossil record at all, 54 genera, or aboutExpand

Phylogeny and evolution of the Betulaceae as inferred from DNA sequences, morphology, and paleobotany.
Phylogeny of the Betulaceae is assessed on the basis of rbcL, ITS, and morphological data. Based upon 26 rbcL sequences representing most "higher" hamamelid families, the Betulaceae are monophyletic,Expand
