Biogeography

Phylogeny and biogeography of Ribes (Grossulariaceae) with an emphasis on North American/Asian disjunctions.

The genus Ribes (Grossulariaceae) comprises between 150 and 200 species of shrubs, with centers of diversity in western North America, east Asia and the Andes of South America. Multiple subgenera within Ribes contain species from both North America and Asia, suggesting a complex biogeographic history of the genus. In an ongoing effort, we are using newly generated sequence data (ETS, ITS and psbA-trnH) and data from Genbank to construct a phylogeny that we use to test biogeographic hypotheses, with an emphasis on North American and Asian taxa. We employ the rich fossil history of the genus to calibrate the phylogeny in order to investigate the extent that vicaricance alone can explain the current and historical distribution of the genus. Our results to date are preliminary, but suggest a more nuanced story than the one inferred from earlier analyses that employed fewer taxa.
