Nitrite-dependent anaerobic methane oxidation (N-DAMO) is a recently discovered process that is performed by “Candidatus Methylomirabilis oxyfera” (M. oxyfera). This process constitutes a unique association between the two major global elements essential to life, carbon and nitrogen, and may act as an important and overlooked sink of the greenhouse gas(More)
Microbial mediated nitrite-dependent anaerobic methane oxidation (N-DAMO), which couples the oxidation of methane to nitrite reduction, is a recently discovered process. The discovery of N-DAMO process makes great contributions to complete the biogeochemical cycles of carbon and nitrogen, and to develop novel economic biotechnology for simultaneous carbon(More)
The anaerobic ammonium oxidation (anammox) process, which can simultaneously remove ammonium and nitrite, both toxic to aquatic animals, can be very important to the aquaculture industry. Here, the presence and activity of anammox bacteria in the sediments of four different freshwater aquaculture ponds were investigated by using Illumina-based 16S rRNA gene(More)
The quantitative importance of anaerobic ammonium oxidation (anammox) has been described in paddy fields, while the presence and importance of anammox in subsurface soil from vegetable fields have not been determined yet. Here, we investigated the occurrence and activity of anammox bacteria in five different types of vegetable fields located in Jiangsu(More)
Methane oxidation coupled to nitrite reduction is mediated by 'Candidatus Methylomirabilis oxyfera' (M. oxyfera), which belongs to the NC10 phylum. In this study, the community composition and diversity of M. oxyfera-like bacteria of NC10 phylum were examined and compared in four different freshwater habitats, including reservoir sediments (RS), pond(More)
China launched the “Returning Grazing Lands to Grasslands” project about a decade ago to restore severely degraded grasslands. Grassland grazing exclusion was one of the experimental approaches for achieving the grand goal. Here, we evaluate the long-term regional ecological effects of grassland grazing exclusion in the Xilingol region of Inner Mongolia,(More)
Burning is one of the most widely used methods for removing crop residues during harvest seasons. It cleans fields faster and costs less in comparison to other residue removal methods. Agricultural burning, however, has been recently limited or banned during harvest seasons in China, mainly due to the air quality and human health concerns raised from its(More)
Despite extensive efforts into the characterization of air pollution during the past decade, real-time characterization of aerosol particle composition above the urban canopy in the megacity Beijing has never been performed to date. Here we conducted the first simultaneous real-time measurements of aerosol composition at two different heights at the same(More)
The sensible heat is an important component in surface energy partitioning over the land surface. This paper compared the sensible heat fluxes measured by a large aperture scintillometer system (LAS) and an eddy covariance system (EC) over a rice paddy with a patch of mulberry seedlings in the east China coastal region during the period from 13 September–11(More)
The modeling ability of a stand-alone version of the Simple Biosphere Model 2 (SiB2) was tested mainly through diagnosing the simulated latent heat (LE), sensible heat (H), CO2 flux, and air temperature at the Tongyu field observation station (44°25′N, 122°52′E, 184 m elevation) of Coordinated Enhanced Observing Period (CEOP), where the land cover is(More)
