“…Our comprehensive mitochondrial phylogeny of Triturus within the Salamandridae, basically supports the taxonomic revisions found in both Garcia-Paris et al (2004) and Litvinchuk et al (2005), although some results agree with the proposal from one team, and others with the suggestions from the other team. Based on our results, we support the following taxonomic revisions with the intent to perturb as little as possible the previously proposed revisions.…”

“…Since Triturus cristatus is the type species of the genus, all members of the clade of LBT (T. cristatus, T. carnifex, T. dobrogicus, T. karelinii, T. marmoratus and T. pygmaeus) should maintain the genus name Triturus. Triturus alpestris and Triturus vittatus could be included in two monotypic genera, that is Mesotriton for T. alpestris (Garcia-Paris et al, 2004) and Ommatotriton for T. vittatus (Litvinchuk et al, 2005). Our data also support the placement of all SBT species (T. boscai, T. helveticus, T. italicus, T. montandoni and T. vulgaris) in their own genus.…”

“…This study supported the grouping of the largebodied species (T. cristatus, T. marmoratus and allies) together with T. alpestris and T. vittatus as one clade, separate from the small-bodied species T. boscai, T. helveticus, T. italicus, T. montandoni and T. vulgaris. The monophyly of Triturus was challenged by the analysis of mtDNA sequence data (Caccone et al, '94, '97; Titus and Larson, '95) and other studies (Steinfartz et al, 2002;Garcia-Paris et al, 2004;Carranza and Amat, 2005;Litvinchuk et al, 2005).

A Bayesian approach on molecules and behavior: reconsidering phylogenetic and evolutionary patterns of the Salamandridae with emphasis on Triturus newts

The monophyly of European newts of the genus Triturus within the family Salamandridae has for decades rested on presumably homologous behavioral and morphological characters. Molecular data challenge this hypothesis, but the phylogenetic position of Triturus within the Salamandridae has not yet been convincingly resolved. We addressed this issue and the temporal divergence of Triturus within the Salamandridae with novel Bayesian approaches applied to DNA sequence data from three mitochondrial genes (12S, 16S and cytb). We included 38 salamandrid species comprising all 13 recognized species of Triturus and 16 out of 17 salamandrid genera. A clade comprising all the ''Newts'' can be separated from the ''True Salamanders'' and Salamandrina clades. Within the ''Newts'' well-supported clades are: Tylototriton-Pleurodeles, the ''New World Newts'' (Notophthalmus-Taricha), and the ''Modern Eurasian Newts'' (Cynops, Pachytriton, Paramesotriton 5 together the ''Modern Asian Newts'', Calotriton, Euproctus, Neurergus and Triturus species). We found that Triturus is a non-monophyletic species assemblage, which includes four groups that are themselves monophyletic: (i) the ''Large-Bodied Triturus'' (six species), (ii) the ''Small-Bodied Triturus'' (five species), (iii) T. alpestris and (iv) T. vittatus. We estimated that the last common ancestor of Triturus existed around 64 million years ago (mya) while the root of the Salamandridae dates back to 95 mya. This was estimated using a fossil-based molecular dating approach and an explicit framework to select calibration points that least underestimated their corresponding nodes. Using the molecular phylogeny we mapped the evolution of life history and courtship traits in Triturus and found that several Triturus-specific courtship traits evolved independently. J. Exp. Zool.

A Bayesian approach on molecules and behavior: reconsidering phylogenetic and evolutionary patterns of the salamandridae with emphasis on Triturus newts. J. Exp. Zool. (Mol. Dev. Evol.) 308B:139-162.Salamanders and newts of the family Salamandridae are at present distributed over North America and Eurasia. Despite a profound diversity in life history traits, including courtship and reproductive modes, the monophyly of the Salamandridae is strongly supported (Weisrock et al., 2005). Among the 17 extant salamandrid genera, the genus Triturus has the widest distribution and the highest number of species, since it is found throughout Europe except for northern Scandina- 308B:139-162 (2007) via and the Mediterranean islands (Fig. 1). The monophyly of Triturus was generally assumed on the basis of overall similarity in morphology and traits of courtship behavior. Triturus newts display a biphasic life style with aquatic reproduction, typically taking place in ponds and stagnant waters during spring and early summer, and a subsequent terrestrial phase until the next reproductive eve...

When two putatively cryptic species meet in nature, hybrid zone analysis can be used to estimate the extent of gene flow between them. Two recently recognized cryptic species of banded newt (genus Ommatotriton) are suspected to meet in parapatry in Anatolia, but a formal hybrid zone analysis has never been conducted. We sample populations throughout the range, with a focus on the supposed contact zone, and genotype them for 31 nuclear DNA SNP markers and mtDNA. We determine the degree of genetic admixture, introgression, and niche overlap. We reveal an extremely narrow hybrid zone, suggesting strong selection against hybrids, in line with species status. The hybrid zone does not appear to be positioned at an ecological barrier, and there is significant niche overlap. Therefore, the hybrid zone is best classified as a tension zone, maintained by intrinsic selection against hybrids. While the two banded newt species can evidently backcross, we see negligible introgression and the pattern is symmetric, which we interpret as supporting the fact that the hybrid zone has been practically stationary since its origin (while extensive hybrid zone movement has been suggested in other newt genera in the region). Our study illustrates the use of hybrid zone analysis to test cryptic species status.

Skull size and shape variation versus molecular phylogeny: a case study of alpine newts (Mesotriton alpestris, Salamandridae) from the Balkan Peninsula

We explored the phylogenetic signal of skull size and shape in alpine newts from the Balkans, a group of European newts that, in spite of their considerable phylogeographic substructuring (as inferred from previous DNA analyses), maintain a conserved phenotype. In terms of skull shape disparity, geometric morphometrics show that the dorsal cranium carries a signiWcant phylogenetic signal, the most notable evidence in this present study. On the contrary, no phylogenetic signal in the shape of the ventral cranium was found. This result indicates that the variation in the shape of the ventral cranium is more prone to other factors and processes, such as adaptations to local environments rather than phylogenetic constraints. Variation in skull size within alpine newts seems to be independent from phylogenetic constraints.
