Abstract Climate change can profoundly impact carbon (C) cycling of terrestrial ecosystems. A field experiment was conducted to examine responses total soil and microbial respiration, biomass experimental warming increased precipitation in a semiarid temperate steppe northern China since April 2005. We measured respiration twice month over the growing seasons, C (MBC) N (MBN), (MR) once year middle season from 2005 2007. The results showed that interannual variations MR, were positively...
A comprehensive and quantitative evaluation of the effects fire on ecosystem nitrogen (N) is urgently needed for directing future research management. This study used a meta-analysis method to synthesize up 185 data sets from 87 studies published 1955 1999. Six N response variables related were examined: fuel amount (FNA) concentration (FNC), soil (SNA) (SNC), ammonium (NH4+) nitrate (NO3−) pools. When all comparisons (fire treatment vs. control) considered together, significantly reduced...
• Global warming and a changing precipitation regime could have profound impact on ecosystem carbon fluxes, especially in arid semiarid grasslands where water is limited. A field experiment manipulating temperature has been conducted temperate steppe northern China since 2005. paired, nested experimental design was used, with increased as the primary factor simulated by infrared radiators secondary factor. The results for first 2 yr showed that gross productivity (GEP) higher than...
Abstract Global surface temperature is predicted to increase by 1.4–5.8°C the end of this century. However, impacts projected warming on soil C balance and budget terrestrial ecosystems are not clear. One major source uncertainty stems from effects microbes, which exert a dominant influence net controlling organic matter decomposition plant nutrient availability. We, therefore, conducted an experiment in tallgrass prairie ecosystem at Great Plain Apiaries (near Norman, OK) study microbial...
Summary Rising atmospheric CO 2 and temperatures are probably altering ecosystem carbon cycling, causing both positive negative feedbacks to climate. Below‐ground processes play a key role in the global (C) cycle because they regulate storage of large quantities C, potentially very sensitive direct indirect effects elevated temperature. Soil organic matter pools, roots associated rhizosphere organisms all have distinct responses environmental change drivers, although availability C...
Abstract Water‐use efficiency (WUE) has been recognized as an important characteristic of ecosystem productivity, which links carbon (C) and water cycling. However, little is known about how WUE responds to climate change at different scales. Here, we investigated leaf, canopy, levels under increased precipitation warming from 2005 2008 in a temperate steppe Northern China. We measured gross productivity (GEP), net CO 2 exchange (NEE), evapotranspiration (ET), evaporation (E), canopy...
Abstract Responses of soil respiration to atmospheric and climatic change will have profound impacts on ecosystem global carbon (C) cycling in the future. This study was conducted examine effects concurrent driving factors elevated CO 2 concentration, air warming, changing precipitation a constructed old‐field grassland eastern Tennessee, USA. Model ecosystems seven species were established open‐top chambers treated with factorial combinations ambient or (+300 ppm) (+3 °C) temperature, high...
Abstract Global nitrogen (N) enrichment and changing precipitation regimes are likely to alter plant community structure composition, with consequent influences on biodiversity ecosystem functioning. Responses of composition N addition increased were examined in a temperate steppe northern China. Increased stimulated suppressed species richness, respectively, across 6 years (2005–2010) the manipulative experiment. significantly altered at functional groups levels. The significant...
Abstract Partitioning soil CO 2 efflux into autotrophic ( R A ) and heterotrophic H components is crucial for understanding their differential responses to climate change. We conducted a long‐term experiment (2000–2005) investigate effects of warming 2°C yearly clipping on its (i.e. in tallgrass prairie ecosystem. Interannual variability these fluxes was also examined. Deep collars (70 cm) were inserted measure . quantified as the difference between Warming treatment significantly stimulated...
Climate change would have profound influences on community structure and composition, subsequently has impacts ecosystem functioning feedback to climate change. A field experiment with increased temperature precipitation was conducted examine effects of experimental warming, their interactions composition in a temperate steppe northern China since April 2005. Increased significantly stimulated species richness coverage plant community. In contrast, warming markedly reduced grasses coverage....
Abstract Soil respiration ( R s ) is the second‐largest terrestrial carbon (C) flux. Although has been extensively studied across a broad range of biomes, there surprisingly little consensus on how spatiotemporal patterns will be altered in warming climate with changing precipitation regimes. Here, we present global synthesis data from studies that have manipulated field by collating 113 increased treatments, 91 decreased and 14 prolonged drought treatments. Our meta‐analysis indicated when...
Summary Stability is an important property of ecological systems, many which are experiencing increasing levels anthropogenic environmental changes. However, how these changes influence ecosystem stability remains poorly understood. We conducted 8‐year field experiment in a semi‐arid natural grassland to explore the effects two common changes, precipitation and nitrogen enrichment, on temporal plant above‐ground biomass. A split‐plot design, with as main plot factor subplot factor, was used....
Changes in soil respiration, one of the major fluxes global carbon cycling, could significantly slow down or accelerate increase atmospheric CO 2 , with consequent feedbacks to climate change. It is critical understand how substrate availability regulates respiration projecting response cycling changed climate. We conducted a clipping and shading experiment for 1 year tallgrass prairie Great Plains, United States, manipulate supply respiration. Our results showed that reduced under and/or...
Abstract In order to facilitate interpretation and comparison of warming effects on ecosystems across various habitats, it is imperative quantify changes in microclimate induced by facilities. This paper reports observed air temperature, soil temperature soil‐moisture content under experimental clipping a tallgrass prairie the Great Plains, USA. We used factorial design with as primary factor nested secondary factor. Infrared heater was simulate climatic mimic mowing for hay or grazing. The...
