| mitochondrial dna evolution and population history of the tenerife skink chalcides viridanus. | recent studies of island lizards have suggested that historical vicariance as a result of volcanism may have played an important role in shaping patterns of within-island genetic diversity. the skink, chalcides viridanus, shows variation in morphology within the volcanic island of tenerife. two mitochondrial dna (mtdna) fragments (from the 12s and 16s rrna regions) were sequenced in individuals from 17 sites to evaluate the relationship between current phylogeography and the geological history o ... | 2000 | 10964225 |
| radiation, multiple dispersal and parallelism in the skinks, chalcides and sphenops (squamata: scincidae), with comments on scincus and scincopus and the age of the sahara desert. | phylogenetic analysis using up to 1325 base pairs of mitochondrial dna from 179 specimens and 30 species of chalcides, sphenops, eumeces, scincopus and scincus indicates that sphenops arose twice independently within chalcides. it is consequently synonymized with that genus. chalcides in this broader sense originated in morocco, diversifying into four main clades about 10 ma, after which some of its lineages dispersed widely to cover an area 40 times as large. two separate lineages invaded the c ... | 2008 | 18276164 |

| tracking down the lizards from gravenhorst's collection at the university of wrocław: type specimens of callopistes maculatus gravenhorst, 1838 and three liolaemus species rediscovered. | johann ludwig christian gravenhorst's herpetological collection at the museum of natural history, university of wrocław included numerous important specimens of amphibians and reptiles. the majority, if not the entirety, of this collection has long been thought to be lost. however, we were able to rediscover some type specimens of lizards. the rediscovered specimens include the holotypes of liolaemus conspersus and l. hieroglyphicus, one syntype of callopistes maculatus (here designated as the l ... | 2019 | 30809465 |
| tooth development in a scincid lizard, chalcides viridanus (squamata), with particular attention to enamel formation. | comparative analysis of tooth development in the main vertebrate lineages is needed to determine the various evolutionary routes leading to current dentition in living vertebrates. we have used light, scanning and transmission electron microscopy to study tooth morphology and the main stages of tooth development in the scincid lizard, chalcides viridanus, viz., from late embryos to 6-year-old specimens of a laboratory-bred colony, and from early initiation stages to complete differentiation and ... | 2005 | 15592752 |
