A new study, described as “The first “big data” analysis of California’s native plants”, was published by the University and Jepson Herbaria, and available on BMC Evolution. The authors focused on the diversity and endemism in the California flora, applying a novel “spatial phylogenetics” approach that makes it possible to evaluate biodiversity from an evolutionary standpoint, including discovering significant areas of neo- and paleo-endemism.
