Article Synopsis
  • CUE (carbon use efficiency) and WUE (water use efficiency) are important measures of how well plants adapt to their environment, and their variations in the Qinghai-Tibet Plateau grasslands (QTPG) are influenced by grazing and climate change.
  • From 1979 to 2018, CUE averaged at 0.7066 and WUE at 0.5591 g C/kg HO, with grazing generally leading to decreased efficiency in both metrics, especially in the northwest region compared to the southeast.
  • The study concludes that changes in CUE and WUE in QTPG are significantly linked to environmental factors and grazing practices, highlighting the need for effective land management

Alpine meadow degradation, usually involving decreased soil nitrogen (N) and patchy landscapes, is a challenge for natural restoration. However, the mechanism underlying plant species coexistence under degradation is unclear. In this study, we evaluated plant N niche complementarity in degraded alpine meadows on the Qinghai-Tibet Plateau using a N-labeling (NO, NH, and N-glycine) experiment.

Climate change and land-use disturbances are supposed to have severely affected the degraded alpine grasslands on the Tibetan Plateau. Artificial grassland establishment has been implemented as a restoration tool against grassland degradation. However, the impact of such degradation and restoration processes on soil microbial communities and soil quality is not clearly understood.

The effects of climate warming and season on soil organic carbon (SOC) have received widespread attention, but how climate warming affects the seasonal changes of SOC remains unclear. Here, we established a gradient warming experiment to investigate plant attributes and soil physicochemical and microbial properties that were potentially associated with changes in SOC at the beginning (May) and end (August) of the growing season in an alpine meadow ecosystem on the Qinghai-Tibet Plateau. The SOC of August was lower than that of May, and the storage of SOC in August decreased by an average of 18.

Estimating the grassland carbon budget is critically important for ensuring that grassland resources are used sustainably. However, the spatiotemporal dynamics of the carbon budget and the response to grazing have not yet been characterized in Qinghai grasslands. Here, we estimated the gross primary productivity (GPP) and net ecosystem exchange (NEE) in Qinghai grasslands using the improved Biome-BGCMuSo model to characterize the spatiotemporal dynamics of the carbon budget and the response to grazing in this region from 1979 to 2018.

Article Synopsis
  • Bunge ex Lehm. is a common perennial herb in northern China, characterized by little yellow flowers and distinct white-tomentose petioles.
  • Researchers extracted genomic DNA from fresh leaves to sequence and assemble the complete chloroplast genome, which is circular and 156,240 bp long.
  • The chloroplast genome includes regions for gene encoding (132 genes total) and provides valuable insights for future research in molecular biology, evolution, and conservation efforts.

The human appropriation of net primary production (HANPP) was developed to estimate the intensity of human activities in natural ecosystems, which is still unclear in the Xinjiang grasslands. Using the Biome-Biogeochemical Cycle (Biome-BGC) grazing model in combination with field data, we assessed the HANPP and explored its spatiotemporal patterns in the Xinjiang grasslands. Our results showed that (1) the HANPP increased from 38 g C/m2/yr in 1979 to 88 g C/m2/yr in 2012, with an average annual increase of 1.

is a perennial grass with considerable academic value as a rare species owing to habitat destruction and a narrow distribution. However, its distribution remains unclear. In this study, we predicted the distribution of in the three-river region (the source of the Yangtze River, Yellow River, and Lancang River) under the context of climate change using the maximum entropy (MaxEnt) model.

Artificial grasslands play a role in carbon storage on the Qinghai-Tibetan Plateau. The artificial grasslands exhibit decreased proportions of graminate and increased species richness with age. However, the effect of the graminate proportions and species richness on ecosystem C stocks in artificial grasslands have not been elucidated.

Allium przewalskianum, a wild onion species growing at altitudes ranging from 1800 to 4500 m, has long been commonly used as an important vegetable and/or condiment by Tibetans, Indians, and Nepalese in the highlands of the Himalayas and adjacent regions. This species comprises both diploids and tetraploids. In this study, we examined the nutritional content and biomass accumulation profiles of two cytotypes, collected from 29 sites, with different altitudinal origins but cultivated in a common garden.

In many plant species, leaf morphology varies with altitude, an effect that has been attributed to temperature. It remains uncertain whether such a trend applies equally to juvenile and mature trees across altitudinal gradients in semi-arid mountain regions. We examined altitude-related differences in a variety of needle characteristics of juvenile (2-m tall) and mature (5-m tall) alpine spruce (Picea crassifolia Kom.
