| coalescent-based species delimitation in the sand lizards of the liolaemus wiegmannii complex (squamata: liolaemidae). | coalescent-based algorithms coupled with the access to genome-wide data have become powerful tools for assessing questions on recent or rapid diversification, as well as delineating species boundaries in the absence of reciprocal monophyly. in southern south america, the diversification of liolaemus lizards during the pleistocene is well documented and has been attributed to the climatic changes that characterized this recent period of time. past climatic changes had harsh effects at extreme lat ... | 2019 | 31128241 |
