dc.description.abstract
Recent conceptual and methodological advances have enabled an increasing number of studies to address the problem of species delimitation in a comprehensive manner. This is of particular interest in cases of species whose divergence times are recent and/or effective population sizes are large, where the conclusions obtained from a single source of evidence may lead to erroneous estimations of true species numbers or incorrect assignment of individuals to species. Iguanian lizards of the Liolaemus kingii group (13 species) comprise an important component of the endemic fauna of Patagonia. The southernmost species of this group (namely L. baguali, L. escarchadosi, L. sarmientoi, and L. tari) show widely overlapping distributions across southern Patagonia, also, their phylogenetic relationships are ambiguous and species boundaries have not been explicitly tested. Here we use a comprehensive approach to assess species limits through the use of molecular and morphological information (mitochondrial cytb, nuclear sequences collected by ddRADseq, and linear, meristic and landmark-based morphometrics). We found support for the current taxonomy given that the different analyses recognized the nominal species (4 entities), also a candidate species was supported by mitochondrial and morphological data. In addition, we detected signs of admixture between some of the species. Our results indicate that the L. kingii group can serve as a model system in studies of diversification accompanied by hybridization in nature, which in turn might have been promoted by past climatic oscillations and generalist morphologies. We emphasize the importance of using multiple lines of evidence in order to solve evolutionary stories, and minimizing potential erroneous results that may arise when relying on a single source of information.
