Other claims from this paper (11)
- Observation Most genetic variation was among populations, with 41.75% between individuals within populations.
- Observation PCoA and clustering distinguished the analyzed populations.
- Observation Siberian and Kola Peninsula populations were most different from each other and had the lowest genetic variability.
- Observation STRUCTURE supported the distinctiveness of the Kola Peninsula population.
- Mechanism Low variability in the Siberian population suggested genetic drift.
- Observation Demographic expansion was indicated without significant bottleneck or founder effect traces.
- Observation Antarctic genetic variation was high and similar to Polish and Balkan populations despite significant bottleneck or founder effect traces.
- Mechanism Multiple introductions from different sources were proposed to explain Antarctic genetic variation.
- Observation Antarctic Poa annua was genetically most similar to European populations.
- Mechanism The authors attributed observed polymorphism to abiotic stress and selection.
- Mechanism Environmental changes were proposed to accelerate evolution through transposon activation and genetic variability.
