- Аннотация: For the first time in Western Siberia, a large-scale study of δ 13 C in oligotrophic Sphagnum mosses is carried out. It is found that mosses of the Sphagnum balticum group and the Shagnum fuscum group have different type of isotopic composition along the meridional gradient. The response of mosses of typical and nontypical habitats to changes in hydrothermal conditions is estimated using correlation and multiple regression analysis. The values of δ 13 C of the Sphagnum balticum mosses group have strong negative correlations with summer temperature characteristics of nontypical habitats and positive correlations with the precipitation regime and hydrothermal coefficient of all habitats. Significant positive correlations of the isotopic composition of Sphagnum fuscum group mosses are found only for a complex hydrothermal coefficient of typical habitats. A multiple regression model taking into account the sum of temperatures above 10 о С, the Selyaninov hydrothermal coefficient, and winter precipitation explains from 26 to 58% of the observed variability of δ 13 C variations for all mosses and all habitats, with the exception of mosses of the Sphagnum fuscum group in all and typical habitats. This confirms the possibility of using Sphagnum mosses for monitoring climate change impacts, the functional state of bogs, as well as for paleoecological and paleoclimatic reconstructions.
