Factors of Spatial and Temporal Variability of Siberian Larch Growth in the Mountain Regions of Altai, Tuva, and Mongolia

The dynamics of radial wood increments have been analyzed according to the three tree-ring chronologies ALT (1463–2017), TUV (1715–2012), and MON (1663–2017) obtained for the southern regions of the Altai Mountains, southwestern regions of Tuva, and northern regions of Mongolian Altai, respectively....

More Information
Summary:The dynamics of radial wood increments have been analyzed according to the three tree-ring chronologies ALT (1463–2017), TUV (1715–2012), and MON (1663–2017) obtained for the southern regions of the Altai Mountains, southwestern regions of Tuva, and northern regions of Mongolian Altai, respectively. Chronologies demonstrate similar annual and long-term temporal variability. Cyclic changes in wood growth with periods of 10–14 and 29–33 years have been revealed. The limiting factor of growth is the air temperature in June–July ( r > 0.7). At the same time, the chronologies are sensitive to the variation in circulatory, hydrological and glaciological parameters.
