From Asia to the Americas: a new cross-continental perspective on viper biogeography and habitat dynamics

Aim: We investigate the biogeographical history of the family Viperidae focusing on how habitat use influenced the geographical range evolution of the group. We tested key hypotheses on origins and biogeographical processes of major clades within Viperidae, including the colonisation of the New World.
Location: Worldwide.
Taxon: Vipers (Serpentes: Viperidae).
Methods: We used four recently published phylogenies of Viperidae and applied Maximum Likelihood (ML) models with trait-specific parameters (habitats) in BioGeoBEARS to estimate ancestral geographical ranges and habitat use.
Results: Our results support an Asian origin for the Viperidae family, with a likely trans-Pacific dispersal to Central America instead of the Beringian land bridge route. The subfamily Viperinae must have originated in Africa, while the genus Lachesis likely emerged in South + Central America. Habitat reconstructions showed varied impacts of forested and open habitats on diversification and biogeographical pro..., , # From Asia to the Americas: a new cross-continental perspective on viper biogeography and habitat dynamics
