Different responses of priming effects in long-term nitrogen- and phosphorus-fertilized soils to exogenous carbon inputs
Long-term nitrogen (N) and phosphorus (P) fertilization could immensely alter plant-soil-microbial properties, thereby impacting the priming effect (PE). However, previous studies mostly simulated PE responses...

Precipitation and land use alter soil respiration in an Inner Mongolian grassland
Grasslands are facing the threat of climate change and intensive land use. Soil respiration (Rs) in grassland ecosystems can be potentially altered by changes in precipitation and land use. We aimed to quantify t...

Responses of soil carbon dynamics to precipitation and land use in an Inner Mongolian grassland
Grasslands hold one of the most important soil carbon stocks in the world, which is vulnerable to climate change (i.e. precipitation) and human disturbance (i.e. land-use). This study aimed to investigate resp...

Resistant soil organic carbon is more vulnerable to priming by root exudate fractions than relatively active soil organic carbon
This study aimed to explore the mechanisms of the priming effect (PE) induced by root exudates on soil carbon pools at different stages of decomposition.

Long-term bare fallow soil reveals the temperature sensitivity of priming effect of the relatively stabilized soil organic matter
Priming effect (PE) plays an important role in modifying the decomposition of soil organic matter (SOM), but large uncertainties remain in the temperature effect on PE mainly due to the variation in SOM stabil...

Inconsistent responses of soil microbial community structure and enzyme activity to nitrogen and phosphorus additions in two tropical forests
Soil microorganisms play an important role in biogeochemical cycles in terrestrial ecosystems. Increasing nitrogen (N) and phosphorus (P) deposition are likely to regulate microbial growth by altering soil nut...

Warming and grazing interact to affect root dynamics in an alpine meadow
Root dynamics plays a fundamental role in determining carbon allocation and other main ecological processes in grasslands. Understanding the responses of root activities to ongoing warming in grazed alpine mea...

Changes in microbial biomass, community composition and diversity, and functioning with soil depth in two alpine ecosystems on the Tibetan plateau
Microbial communities play an important regulatory role in soil carbon and nutrient cycling in terrestrial ecosystems. Most studies on microbial communities and biogeochemical cycling focus on surface soils (0...

Changes of soil organic matter stability along altitudinal gradients in Tibetan alpine grassland
Changes of soil organic matter (SOM) stability in alpine ecosystems can alter carbon release from the soil and consequently feed back to climate change. We sought to explore the altitudinal patterns of SOM sta...

Particulate organic carbon is more vulnerable to nitrogen addition than mineral-associated organic carbon in soil of an alpine meadow
Long-term nitrogen (N) addition can affect soil organic carbon (SOC) pool within different soil fractions with different turnover rates. However, the mechanisms of these effects, particularly in alpine grassla...

Minor responses of soil microbial biomass, community structure and enzyme activities to nitrogen and phosphorus addition in three grassland ecosystems
Human activities have significantly increased nitrogen (N) and phosphorous (P) inputs to terrestrial ecosystems. However, the impact of N and P enrichment on soil microbial community structure and functioning ...

Methodological clarification for estimating the input of plant-derived carbon in soils under elevated CO2 based on a 13C-enriched CO2 labeling experiment
Under the scenario of global change, continuous 13C-enriched CO2 labeling is a powerful tool for evaluating the interaction between plants and soil, especially the influence of elevated CO2 on the input of plant-...

Open Access13C isotope fractionation during rhizosphere respiration of C3 and C4 plants
Stable carbon isotopes are used extensively to partition total soil CO2 efflux into root-derived rhizosphere respiration or autotrophic respiration and soil-derived heterotrophic respiration. However, it remains ...
