Abstract Growing evidence indicates that plant community structure and traits have changed under climate warming, especially in cold or high-elevation regions. However, the impact of these warming-induced changes on ecosystem carbon sequestration remains unclear. Using a warming experiment Qinghai-Tibetan Plateau, we found not only increased species height but also altered composition, collectively resulting taller associated with net productivity (NEP). Along 1,500 km transect promoted NEP...
Abstract Disentangling the relative response sensitivity of soil autotrophic ( R a ) and heterotrophic respiration h to nitrogen (N) enrichment is pivotal for evaluating carbon (C) storage stability in scenario intensified N deposition. However, mechanisms underlying differential sensitivities contribution s with increasing deposition remain elusive. A manipulative field experiment multi‐level addition rates was conducted over 3 years (2015–2017) an alpine meadow explore impact on / ratio...
Abstract Global climate change models predict an increase in the frequency and intensity of extreme droughts, with uncertain ecological impacts across ecosystems. In particular, it is not clear when droughts will elicit responses. For this study, we employed three complementary approaches to explore relationships between drought ecosystem First, used global data mining evaluate relationship gross primary productivity precipitation from 1980 2013. Second, conducted a meta‐analysis using 132...
Abstract Changes in precipitation have the potential to cause dramatic changes ecosystem carbon (C) cycling; however, it remains unclear whether different components of net exchange (NEE) (e.g., C uptake vs. release, plant microbe respiration, above‐ground below‐ground respiration) similar or differential sensitivity gradients. We conducted a manipulative field experiment (from 2015 2017) with six treatments, including 1/12 annual (P), 1/4 P, 1/2 3/4 P and 5/4 an alpine meadow investigate...
Abstract Warming can affect soil microbial respiration by changing biomass and community composition. The responses of to warming under experimental conditions are also related background the setup, such as magnitude, duration, methods. However, global pattern in response underlying mechanisms remain unclear. Here, we conducted a meta-analysis synthesizing data from 187 field experiments. We found that significantly increased carbon 11.8% 6.4%, respectively. warming-induced increase...
The rural digital economy plays an essential role in China’s industrial upgrading, transformation, and urban–rural integration. To determine the state of economy, we constructed a county-level evaluation system using subjective–objective method calculated economic levels 2085 counties. Then, analyzed spatial distribution characteristics, autocorrelation pattern, disequilibrium degree, driving force at county level analysis technology self-organizing feature mapping model. results are as...
Abstract Ecosystem stability is essential to its sustainable functions and services humanity. Although climate warming projected vary from 1 5°C by the end of 21st century, how temporal plant community biomass production responds different scenarios remains unclear. To fill this knowledge gap, we conducted a 6‐year field experiment with three levels treatments (control, +1.5°C, +2.5°C) using infrared radiators, in an alpine meadow on Qinghai–Tibet Plateau. We found that low‐level (+1.5°C),...
Abstract Arbuscular mycorrhizal fungi (AMF) are crucial symbiotic partners for plant nitrogen (N) acquisition and sensitive to exogenous N inputs. However, the AMF mycelial respiration ( R ) has always been overlooked in previous studies, extent which different levels of input can induce changes remains elusive. Based on a long‐term field experiment with gradient addition rates (0, 2, 4, 8, 16, 32 g m −2 year −1 an alpine meadow Qinghai–Tibetan Plateau, we investigated response enrichment...
Abstract The continually increasing nitrogen (N) deposition is expected to cause a saturation response of ecosystem aboveground net primary productivity (ANPP). However, its underlying mechanisms, especially for the decrease ANPP under high N addition rate, remain poorly understood. A field manipulative experiment was conducted investigate six levels rate (0, 2, 4, 8, 16, and 32 g N·m −2 ·year −1 ) in an alpine meadow during 2015–2017. We specifically explored four possible light limitation,...
Climate warming, often accompanied by extreme drought events, could have profound effects on both plant community structure and ecosystem functioning. However, how warming interacts with to affect community- ecosystem-level stability remains a largely open question. Using data from manipulative experiment three treatments in an alpine meadow that experienced one event, we investigated modulates resistance recovery of structural functional facing drought. We found decreased aboveground net...
Abstract Understanding how net primary production (NPP) and its allocation respond to climate warming is of fundamental importance in predicting ecosystem carbon (C) cycle C-climate feedback. Especially, the optimal partitioning theory suggests that plants preferentially allocate photosynthates toward above- or below-ground parts acquire limiting resources maximize their growth rate optimize resource use under environmental change. However, it remains elusive on NPP changes regulates...
Abstract Plant functional traits play important roles in determining plant responses to environmental change and further shaping community composition, but the role of stoichiometry remains poorly understood regulating continually increased nitrogen (N) deposition. In this paper, we used a 5‐year manipulative experiment with six N addition rates (N rate ) explore how response different groups including forbs, grasses, sedges legumes links above‐ground carbon‐to‐N ratio (C:N, related use...
Abstract Nitrogen enrichment impacts ecosystems productivity by altering different hierarchical community processes, ranging from responses of individual species traits to reordering and ultimately turnover. Most previous studies have focussed on examining the these processes separately, but little has been done examine how are linked contribute changes in productivity. To fill this knowledge gap, we conducted a 4‐year nitrogen addition field experiment investigate above‐ground net primary...
