Nitrogen enrichment enhances the competition for nitrogen uptake between Stipa purpurea and microorganisms in a tibetan alpine steppe
Numerous studies have investigated whether plant growth is limited by the availability of nitrogen or phosphorus (or both) in alpine grasslands. However, few studies have assessed N and P limitations on plant ...

High frequency of extreme precipitation increases Stipa grandis biomass by altering plant and microbial nitrogen acquisition
Climate changes are altering precipitation to more frequent extreme precipitation events that have strong impacts on the structure and functions of grassland ecosystems. We conducted a rain simulation experime...

Neighboring tree species alter uptake of NH4+ and NO3− by Chinese fir
Most of the plantations were planted with single species for economic reasons. Continuous planting of such single tree species over a longer period has led to a series of ecological problems including soil deg...

Interactions between intercropped Avena sativa and Agropyron cristatum for nitrogen uptake
The effect of crop** regime on nitrogen (N) uptake in two coexisting plant grass species (Avena sativa and Agropyron cristatum) was investigated.

Three Tibetan grassland plant species tend to partition niches with limited plasticity in nitrogen use
Niche complementarity theory explains how species coexist by using different resources. Two pathways to partition resource have been demonstrated: classical niche differentiation and plasticity in resource use...

Effects of clip** and shading on 15NO3− and 15NH4+ recovery by plants in grazed and ungrazed temperate grasslands
In natural ecosystems, plants generally promote the acquisition of nitrogen (N) through the input of carbon (C) into the soil. The present study aimed to clarify how changes in C input affect N uptake by plants.

Isotopic evidence for oligotrophication of terrestrial ecosystems
Human societies depend on an Earth system that operates within a constrained range of nutrient availability, yet the recent trajectory of terrestrial nitrogen (N) availability is uncertain. Examining patterns ...

Nitrogen Critical Loads for an Alpine Meadow Ecosystem on the Tibetan Plateau
Increasing atmospheric nitrogen (N) deposition has the potential to alter plant diversity and thus the function and stability of terrestrial ecosystems. N-limited alpine ecosystems are expected to be particula...

Climatic patterns modulate ecosystem and soil respiration responses to fertilization in an alpine meadow on the Tibetan Plateau, China
The responses of ecosystem (R ec) and soil (R s) respiration to nutrient enrichment have been extensively investigated, aiding our understanding of ecosystem and soil carbon (C) ba...

Litter species traits, but not richness, contribute to carbon and nitrogen dynamics in an alpine meadow on the Tibetan Plateau
Litter, as afterlife of plants, plays an important role in driving belowground decomposition processes. Here we tested effects of litter species identity and diversity on carbon (C) and nitrogen (N) dynamics d...

Patterns of SOC and soil 13C and their relations to climatic factors and soil characteristics on the Qinghai–Tibetan Plateau
SOC inventory and soil δ13C were widely used to access the size of soil C pool and to indicate the dynamics of C input and output. The effects of climatic factors and soil physical characteristics and plant litte...

Distribution characteristics and influencing factors of soil organic carbon in alpine ecosystems on the Tibetan Plateau transect, China
The undisturbed regions along the Qinghai-Tibet Highway crossing the natural zones of montane desert, alpine meadow-steppe, and montane shrub-coniferous forest were chosen as the study areas. Soil samples were...

Interactions of plant species mediated plant competition for inorganic nitrogen with soil microorganisms in an alpine meadow
Sources of competition for limited soil resources, such as nitrogen, include competitive interactions among different plant species and between plants and soil microbes. We hypothesized that plant interactions...

Importance of clonal plants and plant species diversity in the Northeast China Transect
In plant communities, the internal (genet-level) control mechanisms on a spatio-temporal scale of clonal plants impose strong constraints on spatial pattern as well as on competitive relations and, thus, speci...
