The CH4 concentrations and fluxes increased in the order “spring ≤ summer < autumn” and ranged from 1 to 15 μmol L−1 and 5 to 100 mmol m−2 d−1, respectively. The CO2 concentrations and fluxes (range from 100 to 400 μmol L−1 and 1 to 4 g C m−2 d−1, respectively) were positively correlated with dissolved and particulate organic carbon, total nitrogen and bacterial number of the water column. The CH4 concentrations and fluxes were positively correlated with phosphate and ammonia concentrations. Of the landscape parameters, positive correlations were detected between riparian vegetation biomass and CO2 and CH4 concentrations. Over the six-month open-water period, areal emissions of C (>99.5 % CO2; <0.5 % CH4) from the watersheds of 11 rivers were equal to the total downstream C export in this part of the WSL. Based on correlations between environmental controllers (watershed land cover and the water column parameters), we hypothesize that the fluxes are largely driven by riverine mineralization of terrestrial dissolved and particulate OC, coupled with respiration at the river bottom and riparian sediments. It follows that, under climate warming scenario, most significant changes in GHG regimes of western Siberian rivers located in permafrost-free zone may occur due to changes in the riparian zone vegetation and water coverage of the floodplains.]]> Thu 16 Nov 2023 11:51:49 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001067505 Thu 08 Feb 2024 10:56:19 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000899881 Mon 26 Sep 2022 11:46:47 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001017252 Mon 22 Jan 2024 09:38:56 KRAT ]]>
