Grazing exclusion using fences is a key policy being applied by the Chinese government to rehabilitate degraded grasslands on Tibetan Plateau (TP) and elsewhere. However, there limited understanding of effects grazing alpine ecosystem functions services its impacts herders' livelihoods. Our meta-analyses questionnaire-based surveys revealed that with was effective in promoting aboveground vegetation growth for up four years meadows eight steppes TP. Longer-term fencing did not bring any...
Abstract Aim Climate change is expected to have important effects on plant phenology and carbon storage, with further shifts predicted in the future. Therefore, we proposed community accumulation rate (CAR) from start of growing season (SOS) peak (POS) fill gap that dynamic interactions between research. Location Tibetan Plateau. Major taxa Alpine grassland plants. Time period 2015. Methods We conducted a transect survey across grasslands measure aboveground net primary production...
ABSTRACT Soil erosion can pose a serious problem to environmental quality and sustainable development. On the Tibetan Plateau, soil is one of main challenges regional ecological security. Our analysis investigates evaluates its economic value in alpine steppe, meadow, desert steppe forest ecosystems on Plateau. Analysis was carried out from 1984 2013. The results show that annual average potential erosion, practical conservation calculated by Revised University Loss Equation model were...
In the context of "Carbon Emissions Peak" and Neutrality", grazing exclusion (GE) has been applied widely to rehabilitate degraded grasslands increase carbon sequestration. However, on QingZang Plateau (QZP), impacts GE dynamics alpine are poorly understood, particularly at a regional scale. To fill this knowledge gap, we evaluated responses sequestration in different across QZP by using meta-analysis. The effects ecosystem fractions were dependent duration, grassland types climate factors....
Alpine treelines are projected to shift upslope in response climate warming, but empirical studies have yielded inconsistent results, with both upshifted and stable alpine treelines. Additionally, on different slope aspects of the same mountain can differ. Thus, for a better understanding mechanisms treeline formation responses change, we need elucidate population dynamics at aspects. Here, quantified Balfour spruce (Picea likiangensis var. rubescens) ecotones contrasting north- east-facing...
Abstract Although biotic and abiotic factors have been confirmed to be critical that affect community dynamics, their interactive effects yet fully considered in grassland degradation. Herein, we tested how soil nutrients microbes regulated plant–soil feedback (PSF) a degraded alpine grassland. Our results indicated total carbon (STC; from 17.66 12.55 g/kg) nitrogen (STN; 3.16 2.74 exhibited significant (P < 0.05) decrease non-degraded (ND) severely (SD). Despite higher ND generating...
Leaf nitrogen (N) and phosphorus (P) levels provide critical strategies for plant adaptions to changing environments. However, it is unclear whether leaf N P of different functional groups (e.g., monocots dicots) respond environmental gradients in a generalizable pattern. Here, we used global database determine dicots might have evolved contrasting balance response changes climate soil nutrient availability. Specifically, characterized patterns N, N/P ratio dicots, explored the sensitivity...
Although dissolved organic nitrogen (DON) plays an important role in the dynamic processes of mineralization, fixation, and leaching, ecological driving forces DON across Tibetan Plateau remain largely unknown. Here, we measured climate, soil, plant indicators, concentration on Plateau, used “change-point” analysis to determine patterns. Then correlation was applied analyze relationship between each index. Finally, structural equation modelling (SEM) is explain overall effect environmental...
Abstract There is an urgent need to link grazing exclusion policy and the resulting benefits for fence layout management. However, implementation intensity are rarely considered together. Here, combining changes in rate of livestock fenced area, we constructed a prohibition (GPI) index that reflected implementation. We also quantified ecosystem service (ESBs), including net primary productivity (NPP) soil conservation by different models. Then, new perspective combination with ESBs GPI was...
