Carbon fluxes are valuable indicators of soil and ecosystem health, particularly in the context climate change, where reducing carbon emissions from anthropogenic activities, such as forest fires, is a global priority. This study aimed to evaluate impact prescribed burns on respiration semi-arid grasslands. Two treatments were applied: burn 12.29 ha paddock an introduced grass (Eragostis curvula) with 11.6 t ha−1 available fuel, simulation three fire intensities, over 28 circular plots (80 cm diameter) natural grasslands (Bouteloua gracilis). Fire intensities simulated by burning butane gas inside iron barrel, which represented amounts fuel biomass unburned treatment. Soil was measured chamber two months, readings collected morning afternoon. Moreover, CO2 combustion productivity after treatment quantified. The significantly reduced respiration: all resulted decrease when compared area. Changes albedo increased temperature; however, there no relationship between changes temperature respiration; contrast, precipitation highly stimulated it. These findings suggest that fire, under certain conditions, may not lead more being emitted into atmosphere stimulating respiration, whereas aboveground 60%. However, considering effects long-term nutrient deposition, belowground biomass, properties crucial effectively quantify its cycle.

Abstract The satellite microwave emissivity difference vegetation index (EDVI) has been used in previous studies to estimate FCs and FRP using traditional multivariate linear regression models. However, the nonlinear effects contributions of numerous factors that affect forest fires cannot be disentangled by this model. Using random (RF) model, study utilized multiple EDVIs optical normalized (NDVI) as key fuel properties resolve physical driving mechanisms daily over East Asia. results showed estimated were good agreement with observations, a spatial R 0.59 for 0.63 temporal 0.80 0.81 FRP. integration NDVI into RF model was found improve performance generate overall lower systematic errors than without variables. Model better In addition, greater importance NDVI. This largely due their resolution allowed capture fire dynamics time. combination observations shows great potential FC estimations global danger assessment.

Wildfires are significant disturbances that reshape soil ecosystems, impacting properties, microbial communities, and enzyme activities. In Pinus tabulaeformis forests in northern China, the effects of wildfire on health, particularly Actinobacteriota enzymatic functions, remain poorly understood. This study investigates both direct indirect fire severity these factors examines how fire-induced changes properties mediate responses. Our findings show significantly alters chemical including an increase pH a reduction organic carbon water content, under high severities. These directly impact with showing resilience light moderate intensities but declining severity, especially subsoil layers. Soil enzymes, such as urease protease, played crucial role mitigating negative impacts nutrient cycling. Their activity promoted availability, aiding ecosystem recovery, even intensity reduced overall fertility. Structural Equation Modeling (SEM) further revealed relationships between Actinobacteriota, shaped by thermal complex interactions mediated moisture levels. underscores importance considering mutual activities post-fire recovery. The highlight while high-severity fires disrupt health dynamics, enzymes can help regulate enhancing cycling supporting stability. insights contribute to better understanding wildfire-induced degradation provide actionable strategies for restoration management fire-prone ecosystems.
