A 350-bp fragment of the mitochondrial cytochrome-b gene was sequenced in the Caucasian salamander, Mertensiella caucasica, representing 10 populations from across its range along the Black Sea coast. Five haplotypes were discovered among 65 fragments analyzed, differing at 2-50 positions. The highest differentiation between haplotypes was observed in animals from the eastern part of the species' range (Borjomi) compared to those from the remainder of the species' range. Randomly amplified… 

Phylogeography of two European newt species — discordance between mtDNA and morphology

Patterns of sequence variation within clades suggested long‐term demographic stability in the southern groups, moderate and relatively old demographic growth in the populations inhabiting central Europe, and high growth in some of the groups that colonized northern parts of Europe after the last glacial maximum.

Morphological diversity and phylogeography of the Georgian durmast oak (Q. petraea subsp. iberica) and related Caucasian oak species in Georgia (South Caucasus)

Close intra- and interspecific cpDNA relationships shared with other oaks from bordering countries support the relevant role played by the Colchis region as a primary refugium for the European temperate forest species.

Humid forest refugia, speciation and secondary introgression between evolutionary lineages: differentiation in a Near Eastern brown frog, Rana macrocnemis

The geographic distribution of characters of external morphology, alleles at three polymorphic allozyme loci and mitochondrial DNA haplotypes showed a highly congruent pattern in a limited area of humid forests in the south-west Caucasus, revealing whether or not the forms represent monophyletic evolutionary lineages.

Phylogeography of the Alpine salamander, Salamandra atra (Salamandridae) and the influence of the Pleistocene climatic oscillations on population divergence

The divergence time estimate between several mtDNA haplotypes suggested a pre‐Pleistocene differentiation approximately 3 million years ago, and the impact of the Pleistocene glaciations on the phylogeographical patterns appears to have been secondary, although a somewhat reduced genetic variability was found in populations living in areas that were directly affected by the glaciation.

Genetic subdivision, glacial refugia and postglacial recolonization in the golden‐striped salamander, Chioglossa lusitanica (Amphibia: Urodela)

The golden‐striped salamander (Chioglossa lusitanica) is an ecologically specialized species, endemic to north‐western Iberia, which is consistent with the following hypotheses: subdivision of an ancestral range of the species prior to the middle Pleistocene, secondary contact between populations representing historical refugia, and loss of genetic variation through founder effects during range expansion across major rivers.

Phylogeography and morphological variation in a narrowly distributed Caucasian rock lizard, Darevskia mixta

The Caucasian rock lizard Darevskia mixta was sampled and studied from throughout its range, using mitochondrial cytochrome b sequences and scalation, and the central part of the Lesser Caucasus is suggested to be the ancestral area for the entire D.mixta lineage.

06. Ecological divergence between two evolutionary lineages of the Caucasian salamander: evidence from GIS analysis

The genetic isolation of these two lineages is caused by differential climatic requirements rather than by existing fragmentation of suitable habitats, suggesting that the species from the Greater Caucasus is explained by unsuitable climatic conditions.

Phylogeography of the Poecilimon luschani species group (Orthoptera, Tettigoniidae): a radiation strictly correlated with climatic transitions in the Pleistocene

The genealogical history of the Anatolio−Balkan lineage of the Poecilimon luschani species group was evaluated and it was found that altitudinal heterogeneity played a buffer role during the glacial cycles, allowing populations to cope with severe environmental changes.




Division of this complex into separate species on the basis of the observed patterns of monophyly for mitochondrial DNA is unwarranted because further sampling could reveal additional instances of paraphyly across subspecies and, more generally, because mtDNA alone should not be used to infer species boundaries.

MtDNA phylogeography of the California newt, Taricha torosa (Caudata, Salamandridae).

Thirty-six individuals of the California newt, Taricha torosa, representing 22 populations from throughout the range of the two currently recognized subspecies, torosa and sierrae, were examined for

Influence of the Guadalquivir River Basin on mitochondrial DNA evolution of Salamandra salamandra (Caudata: Salamandridae) from southern Spain

The western region of the Mediterranean Basin has experienced dramatic physiogeographic changes over the last 23 myr during the Miocene and Pliocene periods (L6pez Martinez, 1989). These geologic

Antiquity of clonal salamander lineages revealed by mitochondrial DNA

The low mtDNA variability in the clonal lineages suggests that they have undergone population reductions during the Pleistocene, far longer than estimated for other clonal vertebrate populations.

A Molecular Phylogenetic Perspective on the Evolutionary Radiation of the Salamander Family Salamandridae

Phylogenetic relationships were examined within the salamander family Salamandridae using 18 species representing 14 salamandrid genera and six outgroup taxa from the families Ambystomatidae, Dicamptodontidae, Plethodont families, and Proteidae to test hypotheses of adaptation in the evolution of aquatic suction feeding and terrestrial feeding featuring tongue protrusion.

Mitochondrial DNA rates and biogeography in European newts (genus Euproctus).

The data suggest that the cladogenic events leading to species formation in Euproctus and Triturus occurred very closely in time, indicating that the two genera may not be monophyletic.

Relating Geographic Pattern to Phylogenetic Process

In the lacertid lizard Gallotia galloti (Western Canary islands), it allows the colonization sequence to be hypothesized, giving a new perspective on the causes of morphological differentiation between island populations, and similar work on Anolis oculatus within the island of Dominica raises questions concerning some of the assumptions behind a molecular phylogenetic approach.

Randomly amplified polymorphic DNA analysis of clonal population structure and geographic variation in a freshwater bryozoan

This work is one of the first rapd studies of natural populations, and demonstrates the suitability of the technique for examining population structure and geographic variation in clonal taxa.

The distribution and ecology of the amphibians of Georgia andthe Caucasus: a biogeographical analysis

The analysis of amphibian distribution patterns, both within and outside the Caucasus region, leads to the recognition of five Zoogeographie groups that in term can be arranged into the larger units of (1) amphibians of the Near East and (2) amphibian of the Caucasian Zoogeographsie district.

Newts and Salamanders of Europe

The author examines the life-style of newts and salamanders in folklore, and the relationships between the living tailed amphibians and the environment.
