Abstract Soil microbial respiration is an important source of uncertainty in projecting future climate and carbon (C) cycle feedbacks. However, its feedbacks to warming underlying mechanisms are still poorly understood. Here we show that the temperature sensitivity soil ( Q 10 ) a temperate grassland ecosystem persistently decreases by 12.0 ± 3.7% across 7 years warming. Also, shifts communities play critical roles regulating thermal adaptation respiration. Incorporating functional gene...
Abstract Quantifying soil organic carbon ( SOC ) decomposition under warming is critical to predict carbon–climate feedbacks. According the substrate regulating principle, would decrease as labile declines field warming, but observations of do not always support this prediction. This discrepancy could result from varying changes in components and microbial communities warming. study aimed determine with different turnover times after subjected long‐term and/or root exclusion limit C input,...
A large number of really interesting new gene (RING) E3 ligases contribute to the post-translational modification target proteins during plant responses environmental stresses.However, physical interactome RING in rice remains largely unknown.Here, we evaluated expression patterns 47 Oryza sativa finger protein (OsRFP) genes response abiotic stresses via semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and silico analysis.Subsequently, molecular dissection nine...
Abstract Succession theory predicts altered sensitivity of ecosystem functions to disturbance (i.e., climate change) due the temporal shift in plant community composition. However, empirical evidence global change experiments is lacking support this prediction. Here, we present findings from an 8‐year long‐term experiment with warming and precipitation manipulation (double halved amount). First, observed a species composition over 8 years, resulting transition annual C 3 ‐dominant perennial...
Abstract. Predicting future changes in ecosystem services is not only highly desirable but also becoming feasible as several forces (e.g., available big data, developed data assimilation (DA) techniques, and advanced cyber-infrastructure) are converging to transform ecological research into quantitative forecasting. To realize forecasting, we have an Ecological Platform for Assimilating Data (EcoPAD, v1.0) models. EcoPAD (v1.0) a web-based software system that automates transfer processing...
Abstract Shifts in dominance and species reordering can occur response to global change. However, it is not clear how altered precipitation disturbance regimes interact affect composition dominance. We explored community‐level diversity compositional similarity responses, both across within years, a manipulated gradient annual clipping mixed‐grass prairie Oklahoma, USA. imposed seven treatments (five water exclusion levels [−20%, −40%, −60%, −80%, −100%], addition [+50%], control [0% change...
The western United States is projected to experience more frequent and severe wildfires in the future due drier hotter climate conditions, exacerbating destructive wildfire impacts on forest ecosystems such as tree mortality unsuccessful post-fire regeneration. While empirical studies have revealed strong relationships between topographical information plant regeneration, ecological processes ecosystem models either not fully addressed topography-mediated effects probability of or only...
Abstract Grassland ecosystems provide essential services to society. To maintain ecosystem functions and of grasslands under changing environments, it is critical understand how respond feedback climate change. Here, we present results from a long‐term (16 years) warming clipping (to mimic hay harvesting or grazing) experiment conducted in grassland dominated by C 4 grasses the Great Plains, USA. We analyzed responses net primary production (NPP), aboveground NPP (ANPP), belowground (BNPP)...
Abstract Terrestrial ecosystems can potentially alleviate or exacerbate climate change by regulating atmospheric CO 2 concentration. Divergent predictions of the terrestrial C sink Earth System Models (ESMs) indicate no unified mechanism regarding abiotic and biotic response to change. The amount diversity observations cycle create an opportunity improve predictive capacity C‐cycle models. Modeling study with could provide valuable insights into controls on interannual variability sink. In...
Ubiquitous thermal acclimation of leaf respiration could mitigate the increase. However, whether species different plant functional groups showing distinct or similar justifies simple prediction respiratory carbon (C) loss to a warming climate. In this study, dark (Rd) illinois bundleflower (IB, legume), stiff goldenrod (GR, C3 forbs), indian grass, little bluestem and king ranch (IG, LB KB, C4 grass) were measured with detached leaves sampled in 17-year experiment. The results showed that...

Abstract Soil microbial respiration is an important source of uncertainty in projecting future climate and carbon (C) cycle feedbacks. Despite intensive studies for two decades, the magnitude, direction, duration such feedbacks are uncertain, their underlying mechanisms still poorly understood. Here we examined responses soil community structure to long-term experimental warming a temperate grassland ecosystem. Our results indicated that temperature sensitivity (i.e., Q 10 ) persistently...
