TL;DR: In this paper, a new permafrost map based on freezing and thawing indices from modified MODIS land surface temperatures (LSTs) was generated and validated using various ground-based data sets.
Soil moisture and texture primarily control the soil nutrient stoichiometry across the Tibetan grassland

TL;DR: The results indicated that the nutrient limitation in alpine ecosystem might shifts from N-limited to P-limited or K-limited due to the increase of N deposition and decrease of soil P and K contents under the changing climate conditions and weathering stages, and suggested that soil moisture and mud content could be good predictors of topsoil nutrient stoichiometry in Tibetan grassland.

Soil microbial biomass and activity response to repeated drying–rewetting cycles along a soil fertility gradient modified by long-term fertilization management practices
TL;DR: In this article, the effects of repeated drying-rewetting (DRW) cycles on the microbial biomass and activity in soils taken from long-term field experiment plots with different fertilization (FERT) management practice histories were studied.

Soil Organic Carbon and Its Relationship to Vegetation Communities and Soil Properties in Permafrost Areas of the Central Western Qinghai‐Tibet Plateau, China
Xiaodong Wu,Lin Zhao,Meijun Chen,Hongbing Fang,Guangyang Yue,Ji Chen,Qiangqiang Pang,Zhiwei Wang,Yongjian Ding +8 more
TL;DR: In this paper, soil organic carbon (SOC) contents were examined beneath two grassland vegetation communities and cold desert sites in permafrost areas of the central western part of the Qinghai-Tibet Plateau.

Biomass and Enzyme Activity of Two Soil Transects at King George Island, Maritime Antarctica
D. Tscherko,Manfred Bölter,Lothar Beyer,Ji Chen,Josef Elster,Ellen Kandeler,D. Kuhn,Hans-Peter Blume +7 more
TL;DR: It is shown that enzymes are active in antarctic soils, and that high levels of biomass-based specific activity in the ornithogenic soils, compared to those of mineral soils, result from continuous input of large quantities of enzyme-rich penguin guano.
