| molecular phylogenetics and historical biogeography among salamandrids of the "true" salamander clade: rapid branching of numerous highly divergent lineages in mertensiella luschani associated with the rise of anatolia. | phylogenetic relationships among salamandrids of the "true" salamander clade are investigated using 2019 aligned base positions (713 parsimony informative) of 20 mitochondrial dna sequences from the genes encoding nd1 (subunit one of nadh dehydrogenase), trna(ile), trna(gln), trna(met), nd2, trna(trp), trna(ala), trna(asn), trna(cys), trna(tyr), and coi (subunit i of cytochrome c oxidase), plus the origin for light-strand replication (o(l)) between the trna(asn) and the trna(cys) genes. parsimon ... | 2001 | 11277635 |
| on the origin of and phylogenetic relationships among living amphibians. | the phylogenetic relationships among the three orders of modern amphibians (caudata, gymnophiona, and anura) have been estimated based on both morphological and molecular evidence. most morphological and paleontological studies of living and fossil amphibians support the hypothesis that salamanders and frogs are sister lineages (the batrachia hypothesis) and that caecilians are more distantly related. previous interpretations of molecular data based on nuclear and mitochondrial rrna sequences su ... | 2001 | 11390961 |
| helminth fauna of lycisalamandra billae (franzen & klewen) (luschan salamander) collected from antalya. | fifty (26 males, 21 female and 3 juvenile) lyciasalamandra luschani (luschan's salamander) collected in antalya, were examined for helminths during 1997-2001. in this study, 3 helminth species, aplectana acuminata, cosmocerca longicauda and angiostoma aspersae (nematoda) were found. this study is the first helminthological research of luschan's salamander in the world. this is the first time that luschan's salamander has been shown to be the host of these parasites. | 2008 | 19156619 |
| phylogeny of caecilian amphibians (gymnophiona) based on complete mitochondrial genomes and nuclear rag1. | we determined the complete nucleotide sequence of the mitochondrial (mt) genome of five individual caecilians (amphibia: gymnophiona) representing five of the six recognized families: rhinatrema bivittatum (rhinatrematidae), ichthyophis glutinosus (ichthyophiidae), uraeotyphlus cf. oxyurus (uraeotyphlidae), scolecomorphus vittatus (scolecomorphidae), and gegeneophis ramaswamii (caeciliidae). the organization and size of these newly determined mitogenomes are similar to those previously reported ... | 2004 | 15336675 |
| aspects on the relief of living surfaces using atomic force microscopy allow "art" to imitate nature. | the visualization of the surface of biological samples using an atomic force microscope reveals features of the external relief and can resolve very fine and detailed features of the surface. we examined specimens from the skin of the amphibians salamandra salamandra linnaeus, 1758, lyciasalamandra luschani basoglui baran & atatür, 1980 and mesotriton alpestris laurenti, 1768, and from the surface of pollen grains of the plant species cyclamen graecum link, 1835 and cistus salviifolius linnaeus, ... | 2010 | 21392340 |
| complete nucleotide sequence of the mitochondrial genome of a salamander, mertensiella luschani. | the complete nucleotide sequence (16,650 bp) of the mitochondrial genome of the salamander mertensiella luschani (caudata, amphibia) was determined. this molecule conforms to the consensus vertebrate mitochondrial gene order. however, it is characterized by a long non-coding intervening sequence with two 124-bp repeats between the trna(thr) and trna(pro) genes. the new sequence data were used to reconstruct a phylogeny of jawed vertebrates. phylogenetic analyses of all mitochondrial protein-codi ... | 2003 | 14604788 |
| survey of the oviduct of salamandrids with special reference to the viviparous species. | urodeles include oviparous and a few obligately viviparous species that belong to one family, the salamandridae. oviducts of both groups have basically the same design, but some modifications became necessary as viviparous species evolved. the entire oviduct of urodeles is lined by a monolayered epithelium, which is regionally differentiated into large glands and smaller secretory cells rich in glycoproteins. secretory products important for fertilization form the egg jelly, which also is presen ... | 2005 | 9803537 |
| physicochemical characterization and tissue distribution of esterases in two salamandridae species (mertensiella luschani and salamandra salamandra). | 1. tissue- and species-specificity of the electrophoretic patterns of the multiple molecular forms of esterases were observed in the urodele amphibians mertensiella luschani luschani, m.l. helverseni and salamandra salamandra. all esterases--distributed into two electrophoretic mobility areas in gonads, muscles and brain and into four areas in liver, stomach and intestine--were characterized as carboxylesterases. 2. m. l. luschani and s. salamandra liver esterases were electrofocused into nine a ... | 1989 | 2706937 |
