- Ancient DNA reveals interstadials as a driver of common vole population dynamics during the last glacial periodPublication .

In the case of megafauna, it remains challenging to disentangle climate change and the activities of Palaeolithic hunter-gatherers as the main cause. In contrast, the impact of humans on rodent populations is likely to be negligible. This study investigated which climatic and/or environmental factors affect the population dynamics of the common vole. This temperate rodent is widespread across Europe and was one of the most abundant small mammal species throughout the Late Pleistocene. Location Europe. Taxon Common vole (Microtus arvalis). Methods We generated a dataset comprised of 4.2 kb long fragment of mitochondrial DNA (mtDNA) from 148 ancient and 51 modern specimens sampled from multiple localities across Europe and covering the last 60 thousand years (ka). We used Bayesian inference to reconstruct their phylogenetic relationships and to estimate the age of the specimens that were not directly dated. Results We estimated the time to the most recent common ancestor of all last glacial and extant common vole lineages to be 90 ka ago and the divergence of the main mtDNA lineages present in extant populations to between 55 and 40 ka ago, which is earlier than most previous estimates. We detected several lineage turnovers in Europe during the period of high climate variability at the end of Marine Isotope Stage 3 (MIS 3; 57-29 ka ago) in addition to those found previously around the Pleistocene/Holocene transition. In contrast, data from the Western Carpathians suggest continuity throughout the Last Glacial Maximum (LGM) even at high latitudes. Main Conclusions The main factor affecting the common vole populations during the last glacial period was the decrease in open habitat during the interstadials, whereas climate deterioration during the LGM had little impact on population dynamics. This suggests that the rapid environmental change rather than other factors was the major force shaping the histories of the Late Pleistocene faunas.
- Reconstruction of phylogeographic relationships and evolution of the tundra vole, Alexandromys oeconomus (Rodentia, Cricetidae), based on ancient DNAPublication . Żeromska, Aleksandra; Baca, Mateusz; Lemanik, Anna; Popović, Danijela; Krajcarz, Magdalena; Stojak, Joanna; Stefaniak, Krzysztof; Fewlass, Helen; Fadeeva, Tatyana; Horáček, Ivan; Agadzhanyan, Alexander K.; Serdyuk, Natalia V.; Rhodes, Sara; Conard, Nicolas; Desclaux, Emmanuel; Royer, Aurélien; Pavlova, Svetlana V.; Baláž, Ivan; Rekovets, Leonid; Berto, Claudio; Horvath, Gyozo; Nadachowski, Adam; Mackiewicz, PawełThe Late Pleistocene and Holocene climatic fluctuations profoundly influenced the demographic patterns of many species. Small mammals, particularly rodents, are well-suited for such studies due to their abundance and high environmental sensitivity. A suitable subject is the tundra vole, Alexandromys oeconomus, with changing past and present distributions across the Holarctic. Using ancient DNA, we reconstructed its phylogeography and identified 12 main lineages, including extinct lineages, which highlight greater historical variability of this species. Our analyses revealed eastward and westward expansions, extinctions, and lineage replacements driven by climate changes. Originating in Central/Western Asia, the tundra vole expanded around 110 ka (thousand years ago) into Europe, diversifying into multiple lineages. Two migrations from Central Asia to north-eastern Asia occurred at roughly 70 and 16 ka, and preceded the colonization of North America by 11.5 ka. Europe also experienced intense population turnovers, with remigrations into Western Asia. Fennoscandia was colonized three times after 15 ka by two distinct routes. These migrations were tied to climate changes, with population size increasing during warming periods and declining during cooling periods, especially during the Last Glacial Maximum. This research provides new findings on how climate and environmental shifts shaped the evolution and distribution of A. oeconomus, highlighting the resilience and adaptability of small mammals.
