“…ST5 was significantly higher in the middle of the growing season (July-August) than in September, whereas SWC5 did not differ significantly within the growing season (Figure 4). Ribeiro-Kumara et al (2020) [25] observed a similar pattern of seasonal dynamics in SR, which increased towards summer and decreased towards autumn in all successional stages except in the stage eight years after the fire.…”

“…The SR rates observed in the post-fire plots in Alaska within three years after a fire (0.56-0.62 µmol CO 2 m −2 s −1 , [18]) were within the range we observed in the present study. Ribeiro-Kumara et al (2020) [25] found that in Estonia, the SR rate in an 8-year-old pine stand (1.95 µmol CO 2 m −2 s −1 ) was significantly lower than the SR rate in 179-year-old pine stands (4.31 µmol CO 2 m −2 s −1 ). Sawamoto et al (2000) [26] reported lower SR rates in recently burned larch forests in northeastern Siberia (1.07-1.50 µmol CO 2 m −2 s −1 ) than that in intact larch forests (4.16-4.20 µmol CO 2 m −2 s −1 ) due to low rates of root and microbial respiration.…”

“…For example, SR varied from 5.68 to 17.03 µmol CO 2 m −2 s −1 in 3-100-year-old post-fire pine forests in Canada [21], and from 1.11 to 6.24 µmol CO 2 m −2 s −1 in 1-100year-old fire-affected larch succession in Tura (Siberia, Russia; [29]). In 8-179-year-old fire-affected pine stands in Estonia, SR varied from 1.95 to 6.82 µmol CO 2 m −2 s −1 during the growing season [25]. Yanagihara et al (2000) [47] reported a wide range of SR in Tura larch stands in 2000 (0.6-12.6. µmol CO 2 m −2 s −1 ), which was similar to the range that we observed in the present study.…”

“…The decadal effects of wildfires in the Northern hemisphere, especially on permafrost soils and their CO 2 emissions, are still not well understood [1], even though their importance in the global climate change scenario is well recognized. The effect of the length of post-fire succession on SR dynamics has been studied in Canada [20,21], USA (Alaska) [18,22,23], Estonia [24,25], and Russia [2,[26][27][28][29]. Studies on the impact of forest fires on SR in northern, arctic, and subarctic ecosystems, which were mainly carried out during summer field investigations, showed that forests newly affected by fire are C sources, whereas old forests recovered after fires are C sinks [22,[30][31][32] or are almost C-neutral [33] during the growing season.…”

The observed high spatial variation in soil respiration (SR) and associated parameters emphasized the importance of SR heterogeneity at high latitudes and the involvement of many factors in its regulation, especially within fire-affected areas. The problem of estimating CO2 emissions during post-fire recovery in high-latitude ecosystems addresses the mutual influence of wildfires and climate change on the C cycle. Despite its importance, especially in permafrost regions because of their vulnerability, the mutual influence of these factors on CO2 dynamics has rarely been studied. Thus, we aimed to understand the dynamics of soil respiration (SR) in wildfire-affected larch recovery successions. We analyzed 16-year data (1995–2010) on SR and associated soil, biological, and environmental parameters obtained during several field studies in larch stands of different ages (0–276 years) in the Krasnoyarsk region (Russia). We observed a high variation in SR and related parameters among the study sites. SR varied from 1.77 ± 1.18 (mean ± SD) µmol CO2 m−2 s−1 in the 0–10-year-old group to 5.18 ± 2.70 µmol CO2 m−2 s−1 in the 150–276-year-old group. We found a significant increasing trend in SR in the 88–141-year old group during the study period, which was related to the significant decrease in soil water content due to the shortage of precipitation during the growing season. We observed a high spatial variation in SR, which was primarily regulated by biological and environmental factors. Different parameters were the main contributors to SR in each group, an SR was significantly affected by the inter-relationships between the studied parameters. The obtained results can be incorporated into the existing SR databases, which can allow their use in the construction and validation of C transport models as well as in monitoring global fluctuations in the C cycle in response to climate change.

“…During a wildfire of the above-ground and under-ground plant biomass, the humus layer and soil organic matter are burnt and the greenhouse gases (GHG) e.g. carbon dioxide (CO 2 ), methane (CH 4 ) a dinitrogen monoxide (N 2 O) are being released (Shorohova et al, 2009;Ribeiro-Kumara et al, 2019).…”

Fires have always been a natural component influencing ecosystems and driving their evolution; however, in recent years they have become too frequent and ecosystems are not able to cope with them anymore. Fires destroy the natural vegetation, which prevents the soil erosion, and affect the soil properties which delay the natural recovery of the fire affected area. This experiment was conducted to assess the phytotoxicity of fire affected soil and to investigate whether different soil amendments can help to decrease the negative effect of fire on soil properties. The study utilised the Phytotoxkit TM test. The tested burnt soil was supplemented with 3% w/w of the following individual soil amendments: bentonite, biochar, compost and diatomite. Then, the phytotoxicity tests were carried out with garden cress (Lepidium sativum L.) and white mustard (Sinapis alba L.). The pH and electrical conductivity of soil were measured and it was revealed that the individual soil amendments affected the values of pH and electrical conductivity diversely. The highest root growth stimulation for Sinapis alba L. was observed when diatomite was added, whereas the most favourable amendment for the stimulating root growth of Lepidium Sativum L. were compost, diatomite and biochar, respectively. This study recommended repeated testing for the amendments that show a capability to stimulate the root growth and conducting tests on a wider group of plant species.

Wildfire impacts on soil microbial community structure and functional activity have attracted a growing attention because of the higher sensitivity of soil microbes to wildfire. Soil extracellular enzymes play pivotal roles in biogeochemical processes, such as mediating carbon (C) and nutrient cycling. However, little is known about how post‐fire changes in soil biogeochemical properties and microbial community composition affect soil extracellular enzyme activities. This study explored the responses and regulating factors of C‐, nitrogen‐(N), and phosphorus‐(P) acquiring extracellular enzyme activities across a wildfire chronosequence (i.e., 1, 6, 13, and 50 years after fire) in subtropical–temperate ecotonal forests in Central China. The activities of C‐(β‐glucosidase), N‐(N‐acetylglucosaminidase), and P‐(acid phosphatase) acquiring enzymes declined with time post‐fire, with the highest values one‐year post‐fire. The response of C‐acquiring enzyme activity to fire was positively correlated with bacterial biomass, suggesting that microbial compositions were related to post‐fire changes in extracellular enzyme decomposition. The response of N‐acquiring enzyme activity to fire was positively correlated with soil P availability, while P‐acquiring enzyme activity was positively correlated with soil N availability. Overall, soil extracellular enzyme activity declined with time post‐fire, suggesting wildfire may reduce microbial demand for nutrients over time. Future research is needed to elucidate fire impacts on microbial processes for nutrient‐microbial‐enzyme linkages.
