Patterns of range size and species richness in the North American bryophyte flora.

Recent and ongoing digitization efforts provide the opportunity to access spatial information from hundreds of thousands of herbarium records. Leveraging this dataset, biogeographic patterns of North American bryophytes are explored. Traditional approaches have focused on disjunctions (e.g. between western North America and Europe or eastern North America and east Asia), however this dataset provides the first continent-scale analysis of patterns within the continent. Major differences occur among endemic species (those that occur only in North America) and non-endemics (those also native to another continent). These patterns contribute to both sides of ongoing debate within bryophyte biogeography with respect to the relative importance of relictualism and long-distance dispersal in explaining global patterns of bryophyte biogeography.
