| early stages of divergence: phylogeography, climate modeling, and morphological differentiation in the south american lizard liolaemus petrophilus (squamata: liolaemidae). | this study examines the phylogeographic structure within the patagonian lizard liolaemus petrophilus and tests for patterns of between-clade morphological divergence and sexual dimorphism, as well as demographic and niche changes associated with pleistocene climate changes. we inferred intraspecific relationships, tested hypotheses for historical patterns of population expansion, and incorporated ecological niche modeling (enm) with standard morphological and geometric morphometric analyses to e ... | 2012 | 22837827 |
