We have amplified and sequenced 679 nucleotides of the mitochondrial DNA control-region in 45 Siberian (Capreolus pygargus) and European (C. capreolus) roe deer from two localities in Russia and seven in Italy. Average interspecific sequence divergence was 4.9%. Six different haplotypes were found in Siberian roe deer, and 14 haplotypes in Alpine European roe deer. A population of the endemic Italian subspecies C. c. italicus was monomorphic bearing a single haplotype with one unique nucleotide deletion and a fixed transversion. Phylogenetic relationships among haplotypes indicated that the two species were separated with 100% bootstrap support, and there were two distinct population clusters within each species. These clusters correspond to different geographical locations of the samples: Siberian roe deer were subdivided into west Siberia (Kurgan region) and east Siberia (Amur region), and European roe deer were subdivided into an eastern and a western Alpine group. Average sequence divergence among conspecific populations was 1.2%. Calibrations of evolutionary rates of the different domains of the control-region suggest that Siberian and European roe deer speciated about 2–3 million years ago, and haplotype diversity within species was generated during the last 150 000–370 000 years. Geographical structuring of sequence variability in roe deer allows us to identify historical and recent intraspecific population differences, including the effects of human disturbance. The genetic peculiarities of the endemic Italian subspecies C. c. italicus call for careful conservation of its surviving populations.

Introgressive hybridization is a widespread evolutionary phenomenon which may lead to increased allelic variation at selective neutral loci and to transfer of fitness‐related traits to introgressed lineages. We inferred the population genetic structure of the European roe deer (Capreolus capreolus) in Poland from mitochondrial (CR and cyt b) and sex‐linked markers (ZFX, SRY, DBY4 and DBY8). Analyses of CR mtDNA sequences from 452 individuals indicated widespread introgression of Siberian roe deer (C. pygargus) mtDNA in the European roe deer genome, 2000 km from the current distribution range of C. pygargus. Introgressed individuals constituted 16.6% of the deer studied. Nearly 75% of them possessed haplotypes belonging to the group which arose 23 kyr ago and have not been detected within the natural range of Siberian roe deer, indicating that majority of present introgression has ancient origin. Unlike the mtDNA results, sex‐specific markers did not show signs of introgression. Species distribution modelling analyses suggested that C. pygargus could have extended its range as far west as Central Europe after last glacial maximum. The main hybridization event was probably associated with range expansion of the most abundant European roe deer lineage from western refugia and took place in Central Europe after the Younger Dryas (10.8–10.0 ka BP). Initially, introgressed mtDNA variants could have spread out on the wave of expansion through the mechanism of gene surfing, reaching high frequencies in European roe deer populations and leading to observed asymmetrical gene flow. Human‐mediated introductions of C. pygargus had minimal effect on the extent of mtDNA introgression.

Analysis the of cytochrome b gene (1140 b.p.) polymorphism and polymorphism of 79 specimens of the control region (934 b.p.) of mtDNA of the Siberian roe deer Capreolus pygargus from 23 regions of Russia and Kazakhstan has been carried out. The combined alignment of two fragments of mitochondrial DNA revealed 36 haplotypes, which are distributed in three haplogroups. The net distance was 0.8, 1.3, and 1.3%. The specific pattern of haplogroups was described for roe deer of each region (Ural, trans-Ural, Eastern Siberia, Far East, Northeastern China). Unrelated haplogroups were found in populations of the Urals and Siberia. The variation pattern and spatial distribution of mitochondrial lines allowed us to suggest that a haplogroup that initially belongs to C. p. tianschanicus occurs secondarily in C. p. pygargus.

Analysis of MtDNA cytochrome b gene (1140 bp) polymorphism of 106 samples red deer (Cervus elaphus) from different regions of Eurasia was performed; the phylogenetic relationships of groups throughout the entire inhibiting area (including North America) were reconstructed. Totally 75 haplotypes were detected, 33 of which were found in the European and 42 in the Asian part of the area. There were no identical haplotypes for these two parts of the area found. The close relatedness between Siberian red deer (C. e. sibirica) and North American wapiti (C. e. canadensis) was confirmed. Red deer inhibiting Yakutia were close to the Siberian red deer from Altai and Tuva, whereas red deer inhibiting Krasnoyarsk and Irkutsk regions formed a separate clade. Overall, the reconstructed phylogeographic pattern of the species was significantly different from the subspecies differentiation based on morphological traits.

Abstract Analysis of mtDNA control region (934 b. p.) and cytochrome b gene (1140 b. p.) polymorphism of the 33 roe deer samples from the south-west of Ukraine was carried out. 30 different haplotypes of mtDNA have been described and all of them are related to Capreolus capreolus Linnaeus, 1758. Two well differentiated haplogroups were discovered on the examined territory. The isolated subgroup of related haplotypes was revealed in the Crimea that is likely a result of the long-term geographical isolation of the Crimean roe deer populations.

An analysis of 130 tissue specimens of the European (Capreolus capreolus) and the Siberian (C. pygargus) roe deer from nine regions of Russia and Ukraine using microsatellite loci analysis was conducted, aimed at the identification of hybrid animals. An optimized complex of 21 microsatellite loci was selected for the determination of species specificity and the search for interspecies hybrids. Hybrid animals were revealed in the Moscow and Volgograd regions. Their ratio in the total sample obtained in the European part of Russia was 11.9%.

The macrostructure of the surface of the mucous membrane of the gastrointestinal tract were studied in detail in two hare species (Lepus europaeus and L. timidus) using scanning electron and digital microscopes. The morphology of the gastrointestinal tract of hares, which is similar in the two species studied, was described in detail. The macrostructure of the inner surface of the ileocecal junction was investigated. The particularities of the architectonics of the mucous membrane of the intestine that are specific for hares were revealed. In the jejunum of both hare species, the mucous membrane is represented by villi with merged bases, which form circular plates. The mucosa of the colon forms large conical villi, the surface of which is scattered with secreting cells. The possible functional significance of the revealed morphological particularities is discussed.

Wildlife management systems face growing challenges to cope with increasingly complex interactions between wildlife populations, the environment and human activities. In this position statement, we address the most important issues characterising current ungulate conservation and management in Europe. We present some key points arising from ecological research that may be critical for a reassessment of ungulate management in the future.

A molecular-genetic analysis of the nucleotide sequences of the cytochrome b gene (1140 base pairs) of the mitochondrial DNA and 17 microsatellite loci of eight samples of roe deer from the Samara forest of Dnipropetrovsk oblast (Ukraine) was carried out. For comparison, 212 corresponding mtDNA sequences of the Siberian and European roe deer and data on the variability of microsatellite markers in 49 representatives of these species were included in the study. It was noted that all the analyzed mitochondrial sequences of individuals from the Samara forest are characteristic of the Siberian roe Capreolus pygargus Pallas, 1771. Four haplotypes were described, all of which belonged to the haplogroup typical for the western part of the range of C. pygargus. A fragment analysis of the microsatellite loci of nuclear DNA confirmed the identification of the investigated group with the Siberian species.
