112. New insights into the taxonomy and phylogeny of social voles inferred from mitochondrial cytochrome b sequencesBoris Kryštufek, Tanya Zorenko, Elena Bužan, 2012, original scientific article Abstract: We sequenced the entire cytochrome b gene in Microtus paradoxus from Turkmenistan and Microtus socialis from Crimea and Kalmykia. Phylogenetic relationships among social voles were reconstructed by the inclusion into analyses of a further 23 published haplotypes belonging to six species. The two probabilistic methods which were used in phylogenetic analyses, the Bayesian inference and Maximum Likelihood, yielded very similar results. Both trees showed two highly divergent lineages which were further subdivided into seven species. The socialis lineage encompassed four species (M. socialis, M. irani, M. anatolicus, and M. paradoxus), and the remaining three species clustered into the guentheri lineage (M. guentheri, M. hartingi, M. dogramacii). The ranges for nucleotide divergences between seven species of social voles (4.95-9.28% and 4.18-8.81% for mean and net divergences, respectively) mainly exceeded 4.3%, which is frequently regarded as the conservative cut-off between sibling species in the specious genus Microtus

120. Female reproductive characteristics of the Horvath's rock lizard (Iberolacerta horvathi) from SloveniaKatarina Ljubisavljević, Peter Glasnović, Katja Kalan, Boris Kryštufek, 2012, original scientific article Abstract: In this paper, we present data on the female reproductive traits of the Horvath's rock lizard from Slovenia. The clutch, egg and hatchling characteristics were investigated based on clutches laid in laboratory conditions by pregnant females collected from a natural population. A female lays one clutch of eggs annually with an average number of three (range 1-5) eggs. We found a significant positive correlation between female size and egg width and volume. The mean egg length and volume in a clutch decreased significantly with clutch size independently of female size. The incubation period averaged 44 days. Significant positive correlations were found between the hatchling total length and mass, and egg mass. There was a significant negative relationship between the egg mass and incubation duration. The life-history strategy of the Horvath's rock lizard appeared to be shaped by several factors, such as the constraints of a high-altitude environment, flattened body morphology and possibly phylogenetic background
