Última A morphology-based phylogeny of Phymaturus (Iguania: Liolaemidae) with the description of four new species from Argentina Pap. Avulsos de Zool. (São Paulo) Lobo,Fernando; Quinteros,Sebastián. Phylogenetic relationships within the liolaemid lizard genus Phymaturus were studied using parsimony analysis of morphological data. The data set includes 133 characters: 28 described in the literature as apomorphies of the three genera of Liolaemidae (Ctenoblepharys, Liolaemus, and Phymaturus), 21 published characters of allozymes and karyology, 53 characters taken from external morphology across all terminals of Phymaturus, and 31 from the skeletal anatomy. This data set includes representatives of 10 of the 12 species currently recognized in the literature plus twelve other terminals considered in this study and representing independent lineages assigned to patagonicus or palluma. Four of these terminals are described in the present study as new... Tipo: Info:eu-repo/semantics/article Palavras-chave: Liolaemidae; Phymaturus; New species; Morphology; Phylogenetic analysis.

Avulsos de Zool. (São Paulo) Agnolin,Federico; Jofré,Guillermo. En el presente artículo son reportados ejemplares de diversos taxones de reptiles escamados fósiles procedentes de la base de la Formación Luján (Pleistoceno Superior), en la localidad fosilífera de Merlo, provincia de Buenos Aires, Argentina. Entre los ejemplares registrados se reconoce el primer registro fósil para el género y especie Anops kingii (Amphisbaenidae); asimismo se reporta la presencia de especies indeterminadas de los géneros Homonota (Gekkonidae) y Liolaemus (Liolaemidae). La asociación conjunta de estos tres taxones hoy en día no se encuentra representada en el norte de la provincia de Buenos Aires, siendo la región geográficamente más cercana en donde encuentran una superposición en su distribución el Partido de Balcarce, ubicado en el...

Ano: 2011 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0031-10492011000400001 Sequence variation in the melanocortin-1 receptor (MC1R) pigmentation gene and its role in the cryptic coloration of two South American sand lizards Genet. Mol. Biol. Corso,Josmael; Gonçalves,Gislene L.; Freitas,Thales R.O. de. In reptiles, dorsal body darkness often varies with substrate color or temperature environment, and is generally presumed to be an adaptation for crypsis or thermoregulation. However, the genetic basis of pigmentation is poorly known in this group. In this study we analyzed the coding region of the melanocortin-1-receptor (MC1R) gene, and therefore its role underlying the dorsal color variation in two sympatric species of sand lizards (Liolaemus) that inhabit the southeastern coast of South America: L. occipitalis and L. arambarensis. The first is light-colored and occupies aeolic pale sand dunes, while the second is brownish and lives in a darker sandy habitat. We sequenced 630 base pairs of MC1R in both species. In total, 12 nucleotide polymorphisms were... Tipo: Info:eu-repo/semantics/article Palavras-chave: Adaptation; Body color; Crypsis; Liolaemidae; Pigmentation genes.
