Models of Species Diversification

My research on species diversification models.

Recent radiation and dispersal of an ancient lineage, the case of Fouquieria (Fouquiericeae, Ericales) in North American deserts

Fouqueriaceae, the family of ocotillo and bojum tree, is a monogeneric clade with 11 species. Its siter group, the plox family, Polemoniaceae, has a diversity of 400 species. In this paper, we investigate the processes that have determined the species diversity of Fouquieriaceae.

Uncovering higher-taxon diversification dynamics from clade age and species-richness data

Theory suggests that phylogenetic structure, age type (crown or stem age), and taxonomic delimitation can affect estimates of the age–richness correlation (ARC) considerably. Results from this paper warn against direct interpretations of single ARC estimates and advocate for a more integrative use of ARCs across age types and taxonomic ranks in diversification studies.
