    1. Evidence for extreme sequence divergence between the male- and female-transmitted mitochondrial genomes in the bivalve mollusc, Modiolus modiolus (Mytilidae)

      We demonstrate the doubly uniparental inheritance of mitochondrial DNA in the horse mussel, Modiolus modiolus, using cox1 and rrnL gene sequences. The male mitotype is shown to evolve faster than its female counterpart. Standardized p-distances indicate that M. modiolus displays the highest male-to-female conspecific mitotype sequence divergence for any Mytilidae species thus far examined (38%). This therefore establishes a new threshold for the expected genetic divergence of male mytilid mitochondrial genomes.

    2. Phylogenetic relationships in Kerkia and introgression between Hauffenia and Kerkia (Caenogastropoda: Hydrobiidae)

      Phylogenetic relationships among four species of Kerkia from five localities in Croatia and one in Slovenia, analyzed with one mitochondrial and three nuclear markers, confirmed their distinctness. There was introgression of the Hauffenia mtDNA from central Slovenia into two Kerkia clades from central and southern Croatia, located 210 and 360 km away, respectively. Secondary loss of isolating mechanisms between phylogenetically distant organisms and the severe lack of information on distribution of these underground taxa may explain this unusual phenomenon.

    3. Taxonomic composition and ploidy level among European water frogs (Anura: Ranidae: Pelophylax) in eastern Hungary

      In this study, we investigated the taxonomic and genetic composition of the Pelophylax esculentus complex (formed by Pelophylax ridibundus and Pelophylax lessonae and their hybridogenetic hybrid, Pelophylax esculentus) in eastern Hungary. Molecular taxonomic and population genetic analysis indicated the presence of all members of the P. esculentus complex in the studied localities with exclusively diploid hybrid genotypes. Clonal transfer of the P. ridibundus genome in hybridogenetic lineages was indicated at least in two sampling sites with the novel implementation of population genetic approach.

    4. Searching for the glacial refugia of Erebia euryale (Lepidoptera, Nymphalidae) – insights from mtDNA- and nDNA-based phylogeography in the Western Carpathians

      Our results provide new insights into the phylogeography and origin of Erebia euryale (Esper, 1805). Both mitochondrial and nuclear data reflected a congruent phylogeographic history. The high incidence of unique haplotypes in association with the high variability obtained in the maximum-likelihood analysis of the concatenated data set suggests possible E. euryale re-colonization from south-eastern to northern Europe. The observation that the mean genetic diversity of the Western Carpathian populations indicates either an important refuge area or a contact zone between gene pools during the postglacial re-colonization processes.

    5. Increased genetic structuring of isolated Salamandra salamandra populations (Caudata: Salamandridae) at the margins of the Carpathian Mountains

      To reveal the genetic structure of Salamandra salamandra within the Carpathian Basin, 25 salamander populations were analysed using one mitochondrial (D-loop) and nine nuclear (microsatellites) markers. Our results evidenced significant structuring on the nuclear level, indicating a different origin for eastern (Carpathian) and western (Alpine) populations, independent evolutionary history for Apuseni Mts. population (belonging to Western Carpathians) and a long-time isolation for the marginal populations of the North Hungarian Mountains dating back to the end of the Last Glacial Maximum.

    1. Microsympatry in cryptic lowland salamanders (Caudata: Plethodontidae: Bolitoglossa subgenus Nanotriton) from north-western Honduras: implications for taxonomy and regional biogeography

      The taxonomy of the subgenus Nanotriton has been a source of confusion among specialists, particularly in Honduras. Phylogenetic analysis of sympatric samples collected from the northern slope of the Sierra de Omoa was performed, showing that the samples represent both B. nympha and B. rufescens. Field examination found these taxa to be morphologically indistinguishable, rendering in situ identification of the two species in north-western Honduras problematic. The discovery of another divergent lineage of B. rufescens highlights the need for a taxonomic reassessment.
