Abstract
Due to the multifactorial nature of biological processes, much attention is paid to the contribution of each factor in explaining the variability of the desired trait. The purpose of this study was to compare the contribution of January, average annual and July temperatures to explain the variability of biomass of stands of two-needled pines in Eurasia in the latitudinal gradient from forest tundra to the tropics. To achieve this aim, the WorldClim version 2.1 climate data-base was used, as well as a database on the biomass of Eurasian forests. It was found that the average temperature in January represents the strongest geographically distributed climatic signal and, accordingly, provides the greatest contribution to explaining the variability of both each of the biomass fractions and the average for all fractions. On average, for all fractions, the contribution of climatic variables when including the average temperature of January, the average annual and average temperature of July in the model is 57, 38 and 16 %, respectively. At the same time, the contribution of taxation indicators increases and amounts to 43, 62 and 84 %, respectively, with a slight decrease in the adequacy of the model.
