1. Pan-European phylogeography of the European roe deer (Capreolus capreolus)Kamila Plis, Magdalena Niedziałkowska, Tomasz Borowik, Johannes Lang, Mike Heddergott, Juha Tiainen, Aleksey Bunevich, Nikica Šprem, Ladislav Paule, Aleksey A. Danilkin, Marina Kholodova, Elena Zvychaynaya, Nadezhda Kashinina, Boštjan Pokorny, Katarina Flajšman, 2022, original scientific article Abstract: To provide the most comprehensive picture of species phylogeny and phylogeography of European roe deer (Capreolus capreolus), we analyzed mtDNA control region (610 bp) of 1469 samples of roe deer from Central and Eastern Europe and included into the analyses additional 1541 mtDNA sequences from GenBank from other regions of the continent. We detected two mtDNA lineages of the species: European and Siberian (an introgression of C. pygargus mtDNA into C. capreolus). The Siberian lineage was most frequent in the eastern part of the continent and declined toward Central Europe. The European lineage contained three clades (Central, Eastern, and Western) composed of several haplogroups, many of which were separated in space. The Western clade appeared to have a discontinuous range from Portugal to Russia. Most of the haplogroups in the Central and the Eastern clades were under expansion during the Weichselian glacial period before the Last Glacial Maximum (LGM), while the expansion time of the Western clade overlapped with the Eemian interglacial. The high genetic diversity of extant roe deer is the result of their survival during the LGM probably in a large, contiguous range spanning from the Iberian Peninsula to the Caucasus Mts and in two northern refugia.

2. Phylogenetic relations and range history of jerboas of the Allactaginae subfamily (Dipodidae, Rodentia)Vladimir S. Lebedev, Georgy I. Shenbrot, Boris Kryštufek, Ahmad Mahmoudi, Marina N. Melnikova, Evgeniya N. Solovyeva, Alexandra A. Lisenkova, Enkhbat Undrakhbayar, Konstantin A. Rogovin, Alexey V. Surov, Ana A. Bannikova, 2022, original scientific article Abstract: Five-toed jerboas of the subfamily Allactaginae comprise several complex taxa occurring over a wide distribution range covering a large part of the Eurasian arid belt. In this study, we employed current methods of molecular phylogenetics based on 15 nuclear genes and the mitochondrial gene cytb to revise relations and systematics within Allactaginae. We also applied species distribution modelling projected on paleo-environmental data to reconstruct the geographic patterns of speciation in Allactaginae. We elucidated the intergeneric relationships within this subfamily and clarifed interspecies relations within the genus Scarturus. Moreover, our results demonstrate the species status of S. caprimulga; outline the currently understudied diversity within Orientallactaga, Allactaga, and Pygeretmus; and improve the divergence estimates of these taxa. Based on our results from modelling of geographic range fragmentation in allactagines, we suggest the dating and location of speciation events and present hypotheses regarding general habitat niche conservatism in small mammals.
