    Abstract The genetic diversity of Syphacia nematodes (intestinal parasites of rodents) was studied in the hybrid zone of two sister species of common voles, Microtus arvalis and Microtus obscurus, in the Oka River valley, east of Moscow. Syphacia nematodes of other rodent species (Microtus rossiaemeridionalis, Alexandromys oeconomus, Sylvaemus uralensis, and Apodemus agrarius) that inhabit the area were also studied. Phylogenetic trees for the studied nematodes were inferred from the analysis of nuclear ITS1+5.8S+ITS2, LSU rDNA, and mitochondrial CO1 gene partial sequences. Syphacia nematodes of the studied area form three well-defined clades in the phylogenetic tree of this genus. Morphological analysis revealed similarities between the obtained sequences with those of known Syphacia species from the GenBank database, which enabled identifying these three clades up to the species level: S. montana, S. agraria, and S. frederici. Russian haplotypes of Syphacia are different from West European and East Asian haplotypes with pronounced genetic distances. A high level of specificity was reported for two of these three species (S. frederici, only in Sylvaemus uralensis; S. agraria, only in Apodemus agrarius). S. montana was found in different species of voles. Remarkably, S. montana specimens from M. arvalis and M. obscurus were genetically uniform, while S. montana, specimens from hybrids between these two species formed a separate clade distant from those originating from non-hybridised hosts.

    Abstract Cestodes Paranoplocephala kalelai, which parasitizes in the small intestine of Myodes voles and is distributed in northern Fennoscandia, was found in six habitats in the Asian part of Russia and eastern Kazakhstan, which indicates a wider distribution of P. kalelai on the continent. Analysis of mtDNA showed that P. kalelai is characterized by significant molecular variability in Eurasia. This study complements the data on the distribution of P. kalelai and provides the first molecular data from the territory of Russia and Kazakhstan. The sequence variability of two mitochondrial genes cox1 and nad1 of P. kalelai was studied in two species of voles: gray red-backed Myodes rufocanus and northern red-backed vole Myodes rutilus. Five haplotype groups in the cox1 and nad1 gene networks were identified, and the existence of two mtDNA lines in P. kalelai outside northern Fennoscandia was confirmed. The geographical distribution of the identified haplotypes suggests that the foothills of the Altai-Sayan mountains and southern West Siberia may serve as a refugium for P. kalelai during repeated glaciations.

    Abstract Cestodes Ctenotaenia marmotae are a widespread parasite of Eurasian ground squirrels. Being the only valid species of its genus, it has been recorded in ten host species from the genera Marmota and Spermophilus. Its definitive hosts live in similar ecological conditions and their area covers a wide geographical territory. Therefore, it remained unclear whether C. marmotae is a single species and how high the level of its genetic variability is. The present study analyzed the variability of two mitochondrial cestode genes from four host species from geographically distant localities. Phylogenetic analysis revealed that the newly obtained sequences form a species-level clade with already known sequences from the GenBank. Small genetic distances between the studied sequences indicate low intraspecific genetic variability within the C. marmotae, which may be a consequence of rapid expansion of the cestodes in ground squirrel species inhabiting the flat and mountain steppe landscapes in the past.

    Abstract The Arsi Mountains (Southeastern Ethiopian mountain block) are a unique region comprising a range of habitats, including natural montane forest, extensive ericaceous scrub and small, restricted patches of Afroalpine ecosystem. During 3 years of sampling small mammals, 13 rodent species were recorded, including the extremely rare Mus imberbis and Dendromus nikolausi. Genetic analysis was used to shed light on the taxonomic diversity of rodents in the Arsi Mountains and their evolutionary associations with populations from other Ethiopian montane massifs (including the neighbouring Bale Mountains). All species recorded are endemic to the Ethiopian highlands. The results of this study provide the first genetically confirmed data on the occurrence of such endemic species as Lophuromys melanonyx, L. chrysopus and a yet undescribed Dendromus species in the Arsi Mountains. The genetic affinities of some Arsi rodents with their conspecifics in the neighbouring Bale Mountains were also explored. The results suggest the Arsi Mountains as one of the most important hotspots of unique Ethiopian mammal diversity.

    Abstract Paranoplocephala omphalodes is a widespread parasite of voles. Low morphological variability within the genus Paranoplocephala has led to erroneous identification of P. omphalodes a wide range of definitive hosts. The use of molecular methods in the earlier investigations has confirmed that P. omphalodes parasitizes four vole species in Europe. We studied the distribution of P. omphalodes in Russia and Kazakhstan using molecular tools. The study of 3248 individuals of 20 arvicoline species confirmed a wide distribution of P. omphalodes. Cestodes of this species were found in Microtus arvalis, M. levis, M. agrestis, Arvicola amphibius, and also in Chionomys gud. Analysis of the mitochondrial gene cox1 variability revealed a low haplotype diversity in P. omphalodes in Eurasia.
