Exploring grazing intensity effects: nitrogen uptake in grassland species and soil carbon allocation
Grazing drives carbon (C) and nitrogen (N) dynamics of grasslands through livestock trampling, defoliation, and excretion. Still, the responses of N uptake by plant species and simultaneous C allocation into t...

Clonal integration under heterogeneous water environment increases plant biomass and nitrogen uptake in a temperate steppe
Clonal integration between ramets under heterogeneous environment has crucial implications for the clonal plants, is widely distribute in the arid ecosystems because it helps to transfer water and nutrients fr...

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...

Effects of rotational and continuous overgrazing on newly assimilated C allocation
In situ 13CO2 pulse labeling was conducted in temperate grasslands, managed by no grazing, rotational, or continuous overgrazing, to trace the allocation pattern and the dynamics of newly assimilated C into the p...

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.

The effects of changes in water and nitrogen availability on alien plant invasion into a stand of a native grassland species
Plant invasions are a major component of global change, but they may be affected by other global change components. Here we used a mesocosm-pot experiment to test whether high water availability, nitrogen (N) ...

Nitrogen competition between three dominant plant species and microbes in a temperate grassland
To test the hypothesis that dominant plant species could acquire different nitrogen (N) forms over a spatial scale and they also have the ability to compete for available N with microbes.

Nitrogen acquisition strategies used by Leymus chinensis and Stipa grandis in temperate steppes
Leymus chinensis and Stipa grandis are two important plant species of temperate steppes in Inner Mongolia of North China. They differ in their life forms, e.g., L. chinensis is a type of ...

Open AccessNitrogen acquisition by plants and microorganisms in a temperate grassland
Nitrogen (N) limitation is common in most terrestrial ecosystems, often leading to strong competition between microorganisms and plants. The mechanisms of niche differentiation to reduce this competition remai...

Kin selection or resource partitioning for growing with siblings: implications from measurements of nitrogen uptake
Kin selection and resource partitioning have been proposed to explain interactions between plants growing with siblings (from the same mother). These mechanisms have been examined by measurements of fitness, p...

Interactive effects of soil temperature and moisture on soil N mineralization in a Stipa krylovii grassland in Inner Mongolia, China
Determining soil N mineralization response to soil temperature and moisture changes is challenging in the field due to complicated effects from other factors. In the laboratory, N mineralization is highly depe...

Effect of rainfall interannual variability on the biomass and soil water distribution in a semiarid shrub community
The dynamics of biomass and soil moisture in semiarid land is driven by both the current rainfall and the ecosystem memory. Based on a meta-analysis of existing experiments, an ecosystem model was used to calc...

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...
