Geographic patterns and climatic drivers of the mean genus age of liverworts in North America.

ABSTRACT: Phylogenetic niche conservatism posits that species tend to retain ancestral ecological traits and distributions, which has been broadly tested for lineages originating in tropical climates but has been rarely tested for lineages that originated and diversified in temperate climates. Liverworts are thought to originate in temperate climates. Mean lineage age reflects evolutionary history of biological communities. Here, using regional liverwort floras across a long latitudinal gradient from tropical to arctic climates in North America, we test the age-component of the temperate niche conservatism hypothesis. Mean genus age (MGA) was estimated for each of 76 regional floras of liverworts. We related MGA to climatic variables for North America as a whole and for its eastern and western parts
