Correlation of Lake Tyungyulyu Water Level with Larch Radial Growth in Central Yakutia

Abstract

This study analyzes the monthly and seasonal correlation between the water level in Lake Tyungyulyu and the radial growth of larch across three sites in the Churapcha region of Central Yakutia. The highest Pearson correlation coefficients (r), reaching up to 0.44, have been identified between the water level and the width of the annual rings of larch (Larix cajanderi Mayr) at the third site during the summer-autumn period. These findings suggest the potential of larch in Central Yakutia as an indicator of ecological responses to hydrological conditions and climate changes.
