At the same time, the \(\rm{R_{eco}}\) in the swamps of other climatic zones [61; 62; 63; 64] or other mineral nutrition varies in an extremely wide range from 12 to 337 mgC m\({}^{-2}\) h\({}^{-1}\). It should be emphasized that our measurements were made in field-layer vegetation, and future consideration of tree vegetation will certainly change the resulting estimates for Ridge, Open bog, Ryan, and Tall Ryam; however, the carbon dioxide balance of individual canopy components is important in terms of their contribution to the overall CO\({}_{2}\) cycle [67]. As noted above, the results of estimating the aboveground phytomass stocks of vascular plants are in good agreement with the data obtained in similar ecosystems of Western Siberia [52; 53]. The mass of the green (photosynthetic) parts of mosses varied in our plots from 325 \(\pm\) 93-391 \(\pm\) 59 in E.Hollow and Tall ryam to 579 \(\pm\) 101-519 \(\pm\) 214 g/m\({}^{2}\) in Ridge and Ryam, respectively. According to [52], in hollows, ryam, and tall ryam, the moss phytomass reached 369 \(\pm\) 75, 370 \(\pm\) 88 and 285 \(\pm\) 78 g/m\({}^{2}\), which generally agrees with our results. In [53], for swamps of Western and Eastern Siberia in various natural zones, the green mass of mosses varied from 39 (167)-210 g/m\({}^{2}\) in ridges to 37-450 g/m\({}^{2}\) in hollows. It is possible that the moss phytomass obtained in our study looks somewhat overestimated in Ridge and Ryam, and it would be natural to trace its effect on carbon dioxide fluxes, but such a dependence could not be found. In general, considering the spatial variability and the influence of humid conditions in different years on the amount of moss growth [53], our results are in good agreement with the literature.
