Effect of water temperature on the courtship behavior of the Alpine newt Triturus alpestris [PDF]

open access: yes, 2005
peer reviewedTemperature is expected to have an effect on the behavioral patterns of all organisms, especially ectotherms. However, although several studies focused on the effect of temperature on acoustic displays in both insects and anurans, almost ...

Growth and the expression of alternative life cycles in the salamander \u3ci\u3eAmbystoma talpoideum\u3c/i\u3e (Caudata: Ambystomatidae) [PDF]

open access: yes, 2003
Complex life cycles (CLCs) contain larval and adult phases that are morphologically and ecologically distinct. Simple life cycles (SLCs) have evolved from CLCs repeatedly in a wide variety of lineages but the processes that may underlie the transition ...

Hybridization during altitudinal range shifts: nuclear introgression leads to extensive cyto-nuclear discordance in the fire salamander [PDF]

open access: yes, 2016
Ecological models predict that, in the face of climate change, taxa occupying steep altitudinal gradients will shift their distributions, leading to the contraction or extinction of the high-elevation (cold-adapted) taxa.

The complete mitochondrial genome of Paramesotriton chinensis (Caudata: Salamandridae) and phylogenetic studies of Paramesotriton

open access: yesMitochondrial DNA. Part B. Resources, 2017
The complete mitochondrial genome of the Asian warty newt Paramesotriton chinensis was sequenced. The complete mitogenome of P. chinensis is a circular double-stranded DNA sequence that is 16,361 bp long and was biased toward A + T content at 61.3% (33.0%

Olfactory recognition of terrestrial shelters in female Northern Spectacled Salamanders Salamandrina perspicillata (Caudata, Salamandridae)

open access: yesPhyllomedusa: Journal of Herpetology, 2008
Chemical cues are used as ubiquitous markers of individual, group, kinship, and species identity. Northern Spectacled Salamander (Salamandrina perspicillata) is a semi-terrestrial and elusive species.

Genealogy of the nuclear β-fibrinogen intron 7 in Lissotriton boscai (Caudata, Salamandridae): concordance with mtDNA and implications for phylogeography and speciation [PDF]

open access: yes, 2015
The power of phylogeographic inference resides in its ability to integrate information from multiple sources in an iterative hypothesis- testing framework. In this paper, we build upon previous mtDNA-based hypotheses about the evolutionary history of the

New records of the Turkish Lycian salamanders (Lyciasalamandra: Salamandridae)

open access: yes, 2013
During fieldwork conducted between end of February and mid-April 2012 14 new localities were ascertained for four different taxa of the amphibian genus Lyciasalanzandra (L. I. basoglui, L. I. finikensis, L. arikani and L. atifi). This paper represents the first record of L. I. basoglui from Mug la province (Sakhkent, Fethiye).
