| two dispersed highly repeated dna families of triturus vulgaris meridionalis (amphibia, urodela) are widely conserved among salamandridae. | two bamhi families of repeated sequences were characterized from the genome of the italian smooth newt, triturus vulgaris meridionalis (amphibia, urodela). the first family, which is divided into subfamilies, consists of tandemly arranged arrays whose basic repeat is around 398 bp long; these arrays are dispersed throughout the entire chromosome sets of the various species of triturus tested. moreover the family is widely conserved among salamandridae, being detected by genomic dna blotting of n ... | 1991 | 2009819 |
| sperm morphology of salamandrids (amphibia, urodela): implications for phylogeny and fertilization biology. | mature spermatozoa belonging to four salamander species, salamandrina terdigitata, triturus alpestris, triturus carnifex and triturus vulgaris, have been investigated by electron microscopy. the sperm ultrastructure of these species was compared with that of previously examined urodeles (36 species and 20 genera) and with that of anurans and caecilians. many phylogenetic considerations may be inferred as a consequence of comparative spermatology. urodela appears to be a monophyletic order charac ... | 1997 | 18627832 |
| a molecular assessment of phylogenetic relationships and lineage accumulation rates within the family salamandridae (amphibia, caudata). | we examine phylogenetic relationships among salamanders of the family salamandridae using approximately 2700 bases of new mtdna sequence data (the trnaleu, nd1, trnaile, trnagln, trnamet, nd2, trnatrp, trnaala, trnaasn, trnacys, trnatyr, and coi genes and the origin for light-strand replication) collected from 96 individuals representing 61 of the 66 recognized salamandrid species and outgroups. phylogenetic analyses using maximum parsimony and bayesian analysis are performed on the new data alo ... | 2006 | 16815049 |
| osteology of the italian endemic spectacled salamanders, salamandrina spp. (amphibia, urodela, salamandridae): selected skeletal elements for palaeontological investigations. | salamandrina perspicillata, from northern and central italy, and salamandrina terdigitata, from southern italy, represent a unique case of endemism among the amphibians of europe. some efforts were made to study the biology and ecology of these species, but only few studies focused on their comparative osteology. in particular, detailed descriptions of isolated skeletal elements and comparisons with other european urodeles are not available in literature hindering the identification of their fos ... | 2020 | 32881082 |
| seasonality and microhabitat selection in a forest-dwelling salamander. | many small terrestrial vertebrates exhibit limited spatial movement and are considerably exposed to changes in local environmental variables. among such vertebrates, amphibians at present experience a dramatic decline due to their limited resilience to environmental change. since the local survival and abundance of amphibians is intrinsically related to the availability of shelters, conservation plans need to take microhabitat requirements into account. in order to gain insight into the terrestr ... | 2017 | 28900670 |
| generalisation within specialization: inter-individual diet variation in the only specialized salamander in the world. | specialization is typically inferred at population and species level but in the last decade many authors highlighted this trait at the individual level, finding that generalist populations can be composed by both generalist and specialist individual. despite hundreds of reported cases of individual specialization there is a complete lack of information on inter-individual diet variation in specialist species. we studied the diet of the italian endemic spectacled salamander (salamandrina perspici ... | 2015 | 26292804 |
| using the volumetric indices of telencephalic structures to distinguish salamandridae and plethodontidae: comparison of three statistical methods. | the aim of this study was to establish whether appropriate statistical analysis of 16 volumetric indices corresponding to 16 structures making up the entire telencephalon of urodela could distinguish between two families, salamandridae and plethodontidae. we compared the efficiency of three statistical methods (stepwise discriminant analysis, artificial neural networks, correspondence factor analysis) and the information they provide. all three methods found the same species difficult to classif ... | 2002 | 11846600 |
| spermathecae of salamandrina terdigitata (amphibia: salamandridae): patterns of sperm storage and degradation. | the spermathecae of female salamandrina terdigitata were observed using light and transmission electron microscopy during the fallspring period of sperm storage and secretory activity and during the summer stasis. when sperm are stored inside the spermathecae, the product synthesized by spermathecal epithelial cells is exported into the lumen, where it bathes the sperm. during sperm storage some spermatozoa undergo degradation by the spermathecal epithelium. this process, which includes sperm ca ... | 1995 | 29865306 |

| development of cutaneous glands in salamandrina terdigitata (lacépède, 1788) (amphibia: urodela); findings by light and electron microscopy. | cutaneous glandular anlagen in salamandrina terdigitata appear in the early larval stages as sphere-shaped intraepidermal cell nests. a stromal screen rises into the epidermis from the primordial dermis surrounding the anlagen and isolates them from future keratinous elements. at this stage the only contact between the stroma and the gland blastocytes is through their cell coat, whilst the adjacent keratinocytes show a complex dermo-epidermal type junction. this structural asymmetry, confirmed b ... | 1982 | 7183027 |
