| on gymnodactylus amarali barbour, 1925, with the description of a new species (sauria, gekkonidae). | gymnodactylus amarali barbour, 1925, was previously considered to be a subspecies of g. geckoides, with a wide distribution in the brasilian cerrados. examination of a specimen from alto parnaíba, maranhão, near the type locality (engenheiro dodt, piauí), indicates that it is a proper species, apparently limited to the upper parnaíba basin. the form previously identified as g. geckoides amarali is described as a new species, g. carvalhoi, type locality ipueiras, state of tocantins, thus diagnose ... | 2005 | 16341438 |
| chromosomal evolution in the brazilian geckos of the genus gymnodactylus (squamata, phyllodactylidae) from the biomes of cerrado, caatinga and atlantic rain forest: evidence of robertsonian fusion events and supernumerary chromosomes. | chromosomes of the south american geckos gymnodactylus amarali and g. geckoides from open and dry areas of the cerrado and caatinga biomes in brazil, respectively, were studied for the first time, after conventional and agnor staining, cbg- and rbg-banding, and fish with telomeric sequences. comparative analyses between the karyotypes of open areas and the previously studied atlantic forest species g. darwinii were also performed. the chromosomal polymorphisms detected in populations of g. amara ... | 2009 | 20215729 |
