Long-Term Variability of Anatomic Features of Annual Rings of Coniferous Speciesin Permafrost Zone in Central Siberia
Anatomic structure of annual rings is the key to understanding of adaptive specifics of xylem of various species to climate change. This is especially significant in permafrost zone due to likely permafrost degradation. We compared anatomic features of annual rings of Dahurian larch (Larix gmelinii (Rupr.) Rupr., Larix cajanderi Mayr.), Scots pine (Pinus sylvestris L.) and Siberian spruce (Picea obovata Ledeb.) growing in permafrost zone in Central Siberia for 1960–2011. Climatic factors affecting radial increment and anatomic features of tracheids of coniferous species were recognized.
