“…Obtained results are well agreed with measured fluxes at peatlands in other geographical regions. In particular, NEE at peatbog in the south taiga in the European part of Russia (Ivanov et al, 2017) in summer period 2014 was positive (+200 mg m -2 h -1 ) at hummocks and negative (-79 mg m -2 h -1 ) at hollow sites. Under very dry and hot weather conditions in year 2015, CO 2 balance in hummock and hollow was positive with NEE reached +220 and +31 mg m -2 h -1 , respectively.…”

“…The study of the hydrological and ecological mechanisms controlling peatland response to climate changes is critical to predict potential feedbacks on the global C cycle (Baird et al 2012; The second assessment report… 2014). Recent field studies indicated that the peatland C balance represents a net C sink in intact peatlands in Canada (Wu et al 2010;Munir et al 2014;Webster et al 2018), China (zhu et al 2015zhou et al 2009), Finland (Laine et al 2019;Minkkinen et al 2018), Ireland (Swenson et al 2019), Scotland (Helfter et al 2015), Germany (Günther et al 2017), France (Leroy et al 2017), Poland (Acosta et al 2017), New zealand (Campbell et al 2014), East (Runkle et al 2013;Fleischer et al 2016;Eckhardt et al 2018;Davydov et al 2018) and Western part of Russia Kurganova et al 2011;Molchanov 2015;Ivanov et al 2017).…”

The continuous field measurements of net ecosystem exchange (NEE) of CO 2 were provided at ridge-hollow oligotrophic bog in the Middle Taiga zone of West Siberia, Russia in 2017-2018. The model of net ecosystem exchange of CO 2 was suggested to describe the influence of different environmental factors on NEE and to estimate the total carbon budget of the bog over the growing season. The model uses air and soil temperature, incoming photosynthetically active radiation (PAR) and water table depth, as the key factors influencing gross primary production (GPP) and ecosystem respiration (ER). The model coefficients were calibrated using the data collected by automated soil CO 2 flux system with two transparent long-term chambers placed at large hollow and small ridge sites. Experimental and modeling results showed that the Mukhrino bog acted over the study period as a carbon sink, with an average NEE of-87.7 gC m-2 at the hollow site and-50.2 gC m-2 at the ridge site. GPP was-344.8 and-228.5 gC m-2 whereas ER was 287.6 and 140.9 gC m-2 at ridge and hollow sites, respectively. Despite of a large difference in NEE estimates between 2017 and 2018 the growing season variability of NEE were quite similar.

“…CO 2 fluxes at the ridge-hollow complex differed greatly, between years as well as between microform classes. The dynamics as well as spatial and temporal variability of the CO 2 fluxes for 2014-2015 are described in detail in Ivanov et al (2017), where fluxes on ridges and hollows were combined under one microform type. Here is general information on CO 2 fluxes during 2014-2017 (Fig.…”

The use of unmanned aerial vehicles for detailed mapping of ecosystems has become increasingly important in recent years. As one of the main terrestrial carbon reserves, peatland ecosystems are of the great interest in obtaining highly detailed orthophotoplans. At the same time, there is a lack of publications devoted to the total carbon dioxide fluxes in each type of bog microforms. This paper presents the results of our study, which aimed to develop methods for mapping peatland microlandscapes and for estimation of integral carbon dioxide fluxes between the peatland surface and the atmosphere. Based on a highly detailed orthophotoplan compiled using unmanned aerial vehicles, we assessed the areas of major microform groups (swamps, hollows, and ridges) in a bog located in the Central Forest State Nature Biosphere Reserve (European Russia). The classification accuracy ranged from 79% to 93%. The areas of ridges, hollows, and swamps were 0.16 km 2 , 0.32 km 2 , and 0.12 km 2 , respectively. To make an integral estimation of carbon dioxide fluxes, we used earlier data on carbon dioxide emissions (ecosystem respiration), uptake (gross ecosystem exchange), and balance (net ecosystem exchange) measured by soil chamber method on representative experimental plots of respective microform types. After recalculating fluxes to areas of microforms, the integral values for different classes in the summer seasons of 2014, 2016 and 2017 were 15-91 kg CO 2 × h-1 for ecosystem respiration, 21-190 kg CO 2 × h-1 for gross ecosystem exchange, and from-122 kg CO 2 × h-1 to 41 kg CO 2 × h-1 for net ecosystem exchange. The results of the study confirmed that highly detailed orthophotoplans, obtained with the use of unmanned aerial vehicles, make it possible to distinguish the boundaries of such bog microforms as swamps, hollows and ridges with a high accuracy, despite the presence of some errors in the classification. The study of the structural and functional organisation of the bog should be carried out with considering its seasonal and interannual dynamics as well as all microform types.
