Simulated Yak and Tibetan Sheep Urine Deposition Fleetingly Promoted N2O, CO2 and CH4 Emissions in an Alpine Steppe of Northern **zang Plateau
The urine of yaks (Bos grunniens) and Tibetan sheep (Pantholops hodgsoni) represents a vital source of nutrients in the alpine grasslands on the Qinghai-**zang Plateau, and its crucial role in affecting soil pro...

Topography Variations Alter the Nitrogen Utilization Strategies of Two Dominant Plant Species in an Alpine Steppe
Topographic factors are important potential determinants of soil nitrogen (N) availability as they influence temperature and moisture at the local scale, thereby affecting plant N use strategies. To date, the ...

Seasonal shifting in the absorption pattern of alpine species for NO3− and NH4+ on the Tibetan Plateau
Using an 15N labelling method (15N-NH4+ and 15N-NO3−), we conducted a time series experiment of N absorption for two common plant species (Stipa purpurea and Artemisia nanschanica) in three seasons (summer, late ...

Which root traits determine nitrogen uptake by alpine plant species on the Tibetan Plateau?
Nitrogen (N) is one of the most important limiting factors influencing plant growth and reproduction in alpine and tundra ecosystems. However, in situ observations of the effects of root traits on N absorption...

Nitrogen uptake pattern of herbaceous plants: co** strategies in altered neighbor species
The mechanisms for maintaining the species diversity of plant communities under conditions of resource limitation is an important subject in ecology. How interspecific relationships influence the pattern of nu...

Effects of soil fertility on the N:P stoichiometry of herbaceous plants on a nutrient-limited alpine steppe on the northern Tibetan Plateau
Plant nutrient concentrations and their correlations with soil nutrient conditions are regarded as effective tools for exploring plant adaptation and resource utilisation strategies in a severe environment. Ho...
