Subject:
bioavailability; carbon sinks; gas chromatography-mass spectrometry; lignin; lipids; nuclear magnetic resonance spectroscopy; particle size; particulate organic matter; soil; soil organic matter
Abstract:
... Physical separation of soil into different soil organic matter (SOM) fractions is widely used to identify organic carbon pools that are differently stabilized and have distinct chemical composition. However, the mechanisms underlying these differences in stability and chemical composition are only partly understood. To provide new insights into the stabilization of different chemical compound clas ...

Subject:
Stipa grandis; carbon; carbon cycle; climate change; fine roots; grasses; longevity; models; plant communities; prediction; steppes; sugars; temporal variation; terrestrial ecosystems; China
Abstract:
... Lifespan of fine root plays an important role in regulating carbon (C) cycling in terrestrial ecosystems. Determination of root lifespan and elucidation of its regulatory mechanism in different plant communities are essential for accurate prediction of C cycling from ecosystem to regional scales. There are three major types of grasslands in the temperate steppes of Inner Mongolia, each dominated b ...

Abstract:
... The volumetric quantity and biogeochemical quality of throughfall and stemflow in forested ecosystems are influenced by biological characteristics as well environmental and storm meteorological conditions. Previous attempts at connecting forest water and nutrient cycles to storm characteristics have focused on individual meteorological variables, but we propose a unified approach by examining the ...

4. Mining the isotopic complexity of nitrous oxide: a review of challenges and opportunities

Author:

Biogeochemistry 2017 v.132 no.3 pp. 359-372
ISSN:

Subject:
emissions; funding; gases; greenhouse gases; mass spectrometry; nitrogen; nitrous oxide; oxygen; spectral analysis; stable isotopes
Abstract:
... Nitrous oxide (N₂O) is an important focus of international greenhouse gas accounting agreements and mitigation of emissions will likely depend on understanding the mechanisms of its formation and reduction. Consequently, applications of stable isotope techniques to understand N₂O cycling are proliferating and recent advances in technology are enabling (1) increases in the frequency of isotope anal ...

Abstract:
... Nitrite (NO₂ ⁻) as an important intermediate of the biological nitrogen cycle is particularly reactive in acidic soils and acts as a source of N₂O and NOₓ (NO and NO₂). However, abiotic and biotic pathways of NO₂ ⁻-driven N₂O and NOₓ production in forest soil and the role of soil organic matter (SOM) in these processes are still unclear. In this study, NO₂ ⁻ was applied to both unsterile and steri ...

Subject:
anaerobic ammonium oxidation; aquatic ecosystems; correlation; genes; hydrazine; nitrifying bacteria; nitrogen; phylogeny; riparian areas; rivers; stable isotopes; suspended sediment; Yellow River
Abstract:
... Anaerobic ammonium oxidation (anammox) is believed to be an important sink for fixed inorganic nitrogen in terrestrial and aquatic ecosystems, and many studies have reported that macroscale oxic–anoxic interfaces, such as riparian zones, were hotspots of anammox reaction. However, no research has linked microscale interfaces with the anammox process in natural environments. This study provides evi ...

Abstract:
... Changes in atmospheric deposition, stream water chemistry, and solute fluxes were assessed across 15 small forested catchments. Dramatic changes in atmospheric deposition have occurred over the last three decades, including a 70% reduction in sulphur (S) deposition. These changes in atmospheric inputs have been associated with expected changes in levels of acidity, sulphate and base cations in str ...

Abstract:
... Recent studies on the effects of calcium (Ca) additions on soil carbon (C) cycling in organic soil horizons present conflicting results, with some studies showing an increase in soil C storage and others a decrease. We tested the legacy effects of soil Ca additions on C and nitrogen (N) retention in a long-term incubation of soils from a plot-scale field experiment at the Hubbard Brook Experimenta ...
