chromosomal studies on sphaerodactyl lizards of genera gonatodes and coleodactylus (squamata, gekkonidae) using differential staining and fragile sites analyses. | the karyotypes of three species of sphaerodactyl gekkonid lizards are described after conventional and differential staining. karyotypes of gonatodeshumeralis and g. hasemani are formed by a gradual series of 32 acrocentric chromosomes, similar to those already published for other species of the genus. g. humeralis shows multiple ag-nors with intra-individual variability, and positive c-bands located at centromeric and telomeric regions of several chromosome pairs. coleodactylus amazonicus, the ... | 2003 | 15004475 |
the hidden diversity of coleodactylus amazonicus (sphaerodactylinae, gekkota) revealed by molecular data. | coleodactylus amazonicus, a small leaf-litter diurnal gecko widely distributed in amazon basin, has been considered a single species with no significant morphological differences between populations along its range. a recent molecular study, however, detected large genetic differences between populations of central amazonia and those in the easternmost part of the amazon basin, suggesting the presence of taxonomically unrecognised diversity. in this study, dna sequences of three mitochondrial (1 ... | 2010 | 19818863 |
a new genus of miniaturized and pug-nosed gecko from south america (sphaerodactylidae: gekkota). | sphaerodactyl geckos comprise five genera distributed across central and south america and the caribbean. we estimated phylogenetic relationships among sphaerodactyl genera using both separate and combined analyses of seven nuclear genes. relationships among genera were incongruent at different loci and phylogenies were characterized by short, in some cases zero length, internal branches and poor phylogenetic support at most nodes. we recovered a polyphyletic coleodactylus, with coleodactylus am ... | 2011 | 22125341 |
cranial musculature of south american gekkonidae. | the cranial myology of 13 south american geckos was compared and analyzed for taxonomic significance. the general pattern emerges that muscles in this group do not vary substantially from those of other lizards, except that the geckonids have fewer muscle layers. the former condition is particularly important with respect to the adductor musculature of the jaw, given its fundamental role in the chewing process. a great variety of lizards, both those with the geckonid bauplan and those with other ... | 1996 | 29852594 |
