| a new lizard species of the phymaturus patagonicus group (squamata: liolaemini) from northern patagonia, neuquén, argentina. | the integrative taxonomy framework allows developing robust hypotheses of species limits based on the integration of results from different data sets and analytical methods. in this work, we test a candidate species hypothesis previously suggested based on molecular data, with geometric and traditional morphometrics analyses (multivariate and univariate). this new lizard species is part of the phymaturus patagonicus group (payuniae clade) that is distributed in neuquén and mendoza provinces (arg ... | 2016 | 27395232 |
| a new lizard of the phymaturus genus (squamata: liolaemidae) from sierra grande, northeastern patagonia, argentina. | a new species of lizard of the saxicolous and viviparous genus phymaturus from patagonia is described. the new species is a member of the phymaturus patagonicus species group distributed on volcanic plateaus, mountains or rocky outcrops of southern argentina. phymaturus yachanana sp. nov. differs from the other members of the patagonicus group by a dorsal pattern of small and medium-sized white spots on a brown background, the number of scales around the midbody, genetic differences in mitochond ... | 2014 | 24870155 |
| evidence of body size and shape stasis driven by selection in patagonian lizards of the phymaturus patagonicus clade (squamata: liolaemini). | during the speciation process sibling lineages accumulate differences in time (e.g. genetic, morphological, and/or ecological). phenotypic traits such as size or shape, however, could experience rapid changes or show stasis depending on their role in survival and reproduction. the clade phymaturus patagonicus includes 26 species characterized by a conservative morphology, and all inhabit rock crevice microhabitats in arid environments. in this study we quantify levels of morphological divergence ... | 2018 | 30201426 |
