Arctic genetic trends - lemming in Arctic Russia
Nucleotide diversity estimates based on the complete sequences of mitochondrial genome in the collared lemming indicate how past climate has structured the genetic component of biodiversity. Lower diversity in regions (green) affected by the northward forest expansion during the Holocene warm climatic events compared to Western Beringia, where there was no forest expansion, suggests a reduction of effective size due to regional range contractions during warming events in the Holocene.
