Transformation of climatic response in radial increment of trees depending on topoecological conditions of their occurrence

We report the research results derived from identifying the regional climatic signal contained in the coniferous tree ring-width variability for different topoecological conditions in the forest-steppe of the Republic of Khakassia. It is found that under different growth conditions for trees of the same species the climatic signal undergoes a significant transformation. We demonstrate the possibility of using a combination of tree-ring chronologies of different tree species for an adequate dendroclimatic reconstruction of the leading climatic variables.
