Microbial growth and respiration are at the core of soil carbon (C) cycle, as these microbial physiological performances ultimately determine fate C. C use efficiency (CUE), a critical metric to characterize partitioning between respiration, thus controls sign magnitude C-climate feedback. Despite its importance, response CUE nitrogen (N) input relevant regulatory mechanisms remain poorly understood, leading large uncertainties in predicting dynamics under continuous N input. By combining...
Abstract Unprecedented levels of nitrogen (N) have entered terrestrial ecosystems over the past century, which substantially influences carbon (C) exchange between atmosphere and biosphere. Temperature moisture are generally regarded as major controllers N effects on ecosystem C uptake release. N‐phosphorous (P) stoichiometry regulates growth metabolisms plants soil organisms, thereby affecting many processes. However, it remains unclear how N‐induced shift in plant N:P ratio affects...
Knowledge about changes in plant functional traits is valuable for the mechanistic understanding of warming effects on ecosystem functions. However, observations have tended to focus aboveground traits, and there little information belowground or coordination above- under climate warming, particularly permafrost ecosystems. Based a 7-yr field experiment, we measured 26 four dominant species, explored community composition trait networks response experimental Tibetan Plateau. Experimental...
Abstract As global temperatures continue to rise, a key uncertainty of terrestrial carbon (C)–climate feedback is the rate C loss upon abrupt permafrost thaw. This type thawing—termed thermokarst—may in turn accelerate or dampen response microbial degradation soil organic matter and dioxide (CO 2 ) release climate warming. However, such impacts have not yet been explored experimental studies. Here, by experimentally warming three thermo-erosion gullies an upland thermokarst site combined...

Nitrogen (N) availability is a key regulator of carbon (C) cycling in terrestrial ecosystems. Anthropogenic N input, such as deposition and fertilization, increases soil, which has important implications for an ecosystem's C storage loss. Soil respiration (Rs), the second largest flux from ecosystems to atmosphere, plays role cycles. The direction magnitude responses Rs its components addition have been widely evaluated, but it remains unclear how these processes change across multiple...
Permafrost thaw alters the physical and environmental conditions of soil may thus cause a positive feedback to climate warming through increased methane emissions. However, current knowledge emissions following thermokarst development is primarily based on expanding lakes wetlands, with upland being studied less often. In this study, we monitored during peak growing seasons two consecutive years along sequence within thermo-erosion gully in Tibetan swamp meadow. Both had consistent results,...
Abstract Climate warming can alter ecosystem carbon (C) balance and also the composition of soil organic matter (SOM), with important local global implications. However, extent to which rising temperature affects SOM in permafrost ecosystems remains poorly understood. Here, we experimentally warmed a by open‐top chambers (OTCs) on Tibetan Plateau for 4 years quantify responses C inputs via vegetation production, losses respiration (SOC) stocks top 30 cm. We characterized molecular using 13...
Ecosystem carbon (C) dynamics after permafrost thaw depends on more than just climate change since soil nutrient status may also impact ecosystem C balance. It has been advocated that nitrogen (N) release upon could promote plant growth and thus offset loss. However, compared with the widely accepted C-N interactions, little is known about potential role of phosphorus (P) availability. We combined 3-year field observations along a sequence (constituted by four stages, i.e., non-collapse 5,...
Abstract Cation exchange capacity (CEC) helps soils hold nutrients and buffer pH, making it vital for maintaining basic function of terrestrial ecosystems. However, little is known about the temporal dynamics CEC over broad geographical scales. In this study, we used random forest method to compare historical data from 1980s with new 2010s across northern China's grasslands. We found that topsoil in was significantly lower than 1980s, an overall decline 14%. Topsoil decreased alpine meadow,...
Permafrost thawing may release nitrous oxide (N2O) due to large N storage in cold environments. However, N2O emissions from permafrost regions have received little attention date, particularly with respect the underlying microbial mechanisms. We examined magnitude of fluxes following upland thermokarst formation along a 20-year thaw sequence within thermo-erosion gully Tibetan swamp meadow. also determined importance environmental factors and related functional gene abundance. Our results...
Abstract Emissions of nitrous oxide (N 2 O) contribute to global warming and stratospheric ozone depletion. Anthropogenic N O emissions predominately result from the addition synthetic nitrogen (N) fertilizers terrestrial ecosystems. Usually, an exponential increase in occurs as rates exceed plant demands. However, most evidence date is temperate areas, with little information available for alpine Here we examined changes flux under eight levels mechanisms regulating these a Tibetan steppe....
Large uncertainties exist in carbon (C)-climate feedback permafrost regions, partly due to an insufficient understanding of warming effects on nutrient availabilities and their subsequent impacts vegetation C sequestration. Although a climate may promote substantial release soil the atmosphere, warming-induced increase availability enhance plant productivity, thus offsetting loss from microbial respiration. Here, we present evidence that positive temperature effect dioxide (CO2 ) fluxes be...
Abstract Gross primary productivity (GPP) plays an important role in mediating the feedback between land carbon (C) cycle and climate warming. However, knowledge about mechanisms regulating response of GPP to warming is still limited. Based on a four‐year field manipulative experiment, we examined effects potential typical alpine steppe Tibetan Plateau. Our results revealed that elevated temperature significantly increased over study period. The warming‐induced increase was driven by leaf...
The study of combustion in the plateau environment has gradually aroused interest scholars. Due to particularity environment, these experiments are usually carried out artificial low-pressure chambers. image processing continuous flames recently been widely used scientific research and detection applications for various thermal power devices. In this paper, three methods selecting optimal threshold flame binarization images were investigated by using a video horizontal diesel spray chamber....
Warming-induced permafrost thaw may stimulate soil respiration (Rs) and thus cause a positive feedback to climate warming. However, due the limited in situ observations, it remains unclear about how Rs its autotrophic (Ra) heterotrophic (Rh) components change upon thaw. Here we monitored variations along sequence on Tibetan Plateau, explored potential linkage of (i.e., Ra Rh) with biotic (e.g., plant functional traits microbial diversity) abiotic factors substrate quality). We found that Rh...
