Arctic genetic trends - lemming in Arctic Russia
Year:
2010
Author:
Hugo Ahlenius, UNEP/GRID-Arendal
Description:
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.
