  Scientists Find Rate of Global Soil Organic Carbon Turnover

  Soil organic matter is one of the important carbon pools in terrestrial ecosystem. Its tiny change may alter the variation in the concentration of greenhouse gases and then the temperature of earth surface.

  Determining the main drivers of coarse woody productivity in temperate mixed forests

  As the main part of terrestrial biosphere, forest ecosystems play an important role for the global regulation of carbon, a substantialportion of which is maintained in above-ground biomass. Yet, it is still poorly understood what factors are drivingforest aboveground biomass productivity. While it is well understood forest productivity may be simultaneously driven by different abiotic factors (i.e. soil nutrients) and biotic factors (i.e. the diversity, trait composition and initial stand biomass) at local scale, the relative strengths of thesedrivers have not been investigated in temperate forests.

  Scientists Find Soil Microbial Functional Gene Beta-diversity Is Determined By the Variation in Aboveground Plant Biomass Composition

  Understanding linkages between the diversity of organisms aboveground and that of organisms belowground constitutes an important challenge for our knowledge of the maintenance and stability of ecosystem processes. Increased attention has been paid to the biodiversity linkages between aboveground and belowground biological communities in last decade.

  Researchers Quantify the Community-level Stoichiometric Traits to Nitrogen Enrichment and Precipitation Changes

  Stoichiometric traits in plants are important drivers for several fundamental ecological processes , including primary productivity , herbivory , and nutrient cycling .While there is mounting evidence for the substantial species-specific variation in the responses of plant stoichiometric traits to global change drivers , we still know little about such changes at community-level .

  Scientists Underpin Varying and Constant Settings Determine Microbial Responses to Temperature

  Lab incubation experiments are always used to simulate nutrition cycling in response to global warming under constant and/or varying status .The scientists from Research Group of Soil Fertility and Nutrient Cyclingin Institute of Applied Ecology ( IAE ) of the Chinese Academy of Sciences ( CAS ) conducted a 4 - month incubation study to test for differences between varying and constant temperature settings in changing the thermal acclimation of microorganisms derived from different forest stands and soil horizons .

  Researchers Quantify the Sources of Extractable Organic Nitrogen in Agricultural Soil

  Soil extractable organic nitrogen ( EON ) , also called soil soluble organic nitrogen ( SON ) , is defined as the organic forms of N that are extracted by water or salt solutions ( e . g . , K2SO4 .The research results were published in a top journal of soil science “ Soil Biology and Biochemistry ” as a Short Communication Paper entitled “ Formation of extractable organic nitrogen in an agricultural soil : a 15N labeling study ” . The work was supported by Strategic Priority Research Program .
