چکیده

A portion of the mitochondrial DNA from the 3' terminal of gene 12S rRNA to the 5' extremity of 16S rRNA gene has been amplified by PCR from Salamandra atra aurorae genomic DNA in order to define the taxonomic position of S. atra aurorae within the Salamandra species. Analysis of the molecular data indicated that S. a. aurorae is quite different from S. salamandra, whereas S. a. aurorae and S. a. atra are more similar, although their mitochondrial DNA present several mutations. Our analysis suggested therefore that S. a. aurorae could really represent a new subspecies of alpine salamander. Finally, on the basis of the rate of sequence divergence, we could suggest that S. a. atra and S. a. aurorae diverged about three million years ago.

Tracing the first step to speciation: ecological and genetic differentiation of a salamander population in a small forest.

Mechanisms and processes of ecologically driven adaptive speciation are best studied in natural situations where the splitting process is still occurring, i.e. before complete reproductive isolation is achieved. Here, we present a case of an early stage of adaptive differentiation under sympatric conditions in the fire salamander, Salamandra salamandra, that allows inferring the underlying proc...

Detecting a hierarchical genetic population structure: the case study of the Fire Salamander (Salamandra salamandra) in Northern Italy

The multistep method here applied in studying the genetic structure of a low dispersal and philopatric species, such as the Fire Salamander Salamandra salamandra, was proved to be effective in identifying the hierarchical structure of populations living in broad-leaved forest ecosystems in Northern Italy. In this study, 477 salamander larvae, collected in 28 sampling populations (SPs) in the Pr...

Identification of conservation units of the hynobiid salamander Pachyhynobius shangchengensis.

The evolutionary significant units (ESUs) of the salamander Pachyhynobius shangchengensis (Hynobiidae) in the Dabieshan mountains, southeastern China, were identified based on mitochondrial DNA data. We used methods for detecting cryptic species, such as the minimum spanning tree, the automatic barcode gap discovery, and the generalized mixed Yule-coalescent model; geographical partitioning was...

Salamandra robotica : a biologically inspired amphibious robot that swims and walks

One of the key characteristics of animals, perhaps the most impressive, is their ability to move. It is the result of millions of years of evolution, and its complexity, flexibility and energy efficiency are yet to be approached by robots. The control and coordination of many degrees of freedom in a robot is complex, and there is not well established technique to deal with this: on their side, ...
