“…One of them, the sika deer ( Cervus nippon ), was deliberately introduced to many European countries for hunting [ 109 ], which has led to hybridization with native deer species in some regions [ 110 , 111 , 112 ]. Another cervid, European roe deer ( Capreolus capreolus ), is known to hybridize with Siberian roe deer ( Capreolus pygargus ) [ 15 , 113 ] and Italian roe deer ( Capreolus c. italicus ) [ 114 ]. Although natural processes (e.g., range expansion) could have caused hybridization in this genus, human-mediated introductions of Siberian roe deer, aimed at increasing body mass and trophy size of European roe deer, affected the rate of hybridization between these species [ 15 ].…”

Hybridization, defined as breeding between two distinct taxonomic units, can have an important effect on the evolutionary patterns in cross-breeding taxa. Although interspecific hybridization has frequently been considered as a maladaptive process, which threatens species genetic integrity and survival via genetic swamping and outbreeding depression, in some cases hybridization can introduce novel adaptive variation and increase fitness. Most studies to date focused on documenting hybridization events and analyzing their causes, while relatively little is known about the consequences of hybridization and its impact on the parental species. To address this knowledge gap, we conducted a systematic review of studies on hybridization in mammals published in 2010–2021, and identified 115 relevant studies. Of 13 categories of hybridization consequences described in these studies, the most common negative consequence (21% of studies) was genetic swamping and the most common positive consequence (8%) was the gain of novel adaptive variation. The total frequency of negative consequences (49%) was higher than positive (13%) and neutral (38%) consequences. These frequencies are biased by the detection possibilities of microsatellite loci, the most common genetic markers used in the papers assessed. As negative outcomes are typically easier to demonstrate than positive ones (e.g., extinction vs hybrid speciation), they may be over-represented in publications. Transition towards genomic studies involving both neutral and adaptive variation will provide a better insight into the real impacts of hybridization.

“…Recent studies showed the introgression of the Siberian roe deer mtDNA genes into the eastern populations of the European roe deer (Kashinina et al, 2018; Lorenzini et al, 2014; Markov et al, 2016; Matosiuk et al, 2014). This showed a new level of the genetic complexity in the species and opened a debate on the sources of that admixture (Kashinina et al, 2018; Lorenzini et al, 2014; Matosiuk et al, 2014; Świsłocka et al, 2019). However, the limited sampling (Lorenzini et al, 2014) did not allow to define whole spatial range at which the introgression has occurred.…”

Climate fluctuations during the Last Glacial Period between 115,000 and 11,500 years ago (Lokrantz & Sohlenius, 2006) played an important role in shaping the current species composition, distribution, and genetic diversity of mammals in Europe. During glaciations, the ranges of cold sensitive species were limited to refugial areas located in the Balkan, the Iberian and the Apennine Peninsulas (Hewitt, 2004;Taberlet et al., 1998) and south-eastern part of the continent (the Black Sea region and the Caucasus Mts.; Markova & Puzachenko, 2019). Contribution of a given refugium into postglacial recolonization processes varied a lot among species such as, for example, red deer Cervus elaphus (Niedziałkowska, Doan, et al., 2021), wild boar Sus scrofa (Niedziałkowska, Tarnowska, et al., 2021), or common vole Microtus arvalis (Stojak et al., 2015). Cold-adapted species such as, for example, reindeer Rangifer tarandus (Sommer et al., 2014), saiga antelope Saiga tatarica (Nadachowski et al., 2016), or arctic fox Alopex lagopus (Dalén et al., 2007), thrived in the glacial stages, expanded their ranges southward, and during the onset of interglacial they underwent massive, large-scale extinctions. Species of mammals that have very broad biogeographic niche (from the Mediterranean to the boreal zone) had more diverse response to geological time-scale pulsation of climate, most likely with several glacial refugia located at both lower and higher latitudes, where subpopulations diverged into different lineages and could have developed adaptations to different climate, habitat, and food-related conditions. Examples of such species include the bank vole Clethrionomys glareolus (Tarnowska et al.,

“…Among ungulates, the evidence of hybridization varies in different countries [59][60][61][62][63]. The volume and effects of anthropogenic hybridization and wildlife translocations can differ region to region, as well as the efficiency of efforts of wildlife conservation or national prevention [21].…”

Molecular sexing techniques are widely applied in conservation biology, although the range of forensically validated methods is fairly limited. The primary aim of this work was to develop forensically validated assays, using two PCR panels for sex and species assignment for the abundant antlered European game species: red deer (Cervus elaphus), roe deer (Capreolus capreolus) and fallow deer (Dama dama). Segments of the SRY and Amelogenin X/Y genes for sex determination, additionally species-specific cytochrome b regions for species detection were targeted and separately amplified in two multiplex reactions. These assays can reliably analyze trace amounts of DNA. The results of both can easily be visualized and interpreted practically, either on agarose gel or by capillary electrophoresis. These simple, fast molecular assays are able to affect the early-stage resolution of disputed or unsolved poaching cases, without the need of individualization or sequencing of forensic samples.
