TL;DR: The patterns of population subdivision superimposed on interpolated fossil pollen distributions indicate that survival in separate refugia and postglacial colonization has led to significant structuring of genetic variation in the southern range of the Norway spruce species.

TL;DR: It is hypothesize that temperature during zygotic embryogenesis and seed maturation regulates an 'epigenetic memory' in the progeny, involving differential expression of genes that may regulate bud phenology, cold acclimation and embryogenesis in Norway spruce.

TL;DR: In this paper, the importance of forest genetic resources as a source of evolutionary potential for adaptation to changes in climate and other ecological factors is reviewed and recommendations for policy-makers are provided.

TL;DR: Comparing variation at seven highly variable nuclear microsatellite loci in 37 populations with mitochondrial DNA variation suggests that the loss of nuclear diversity after postglacial colonization has been efficiently replenished by pollen-mediated gene flow in the south, and towards the north, smaller effective population size may have caused decreased nuclear diversity and increased inbreeding.

TL;DR: Norway spruce has developed a memory mechanism, regulating adaptive plasticity by photoperiod and temperature, which could counteract harmful effects of a rapidly changing climate.
