Diversity of active root-associated methanotrophs of three emergent plants in a eutrophic wetland in northern China

AMB Express, 2020
Root-associated aerobic methanotrophs play an important role in regulating methane emissions from the wetlands. However, the influences of the plant genotype on root-associated methanotrophic structures, especially on active flora, remain poorly ...

Elevated CO2 and Warming Altered Grassland Microbial Communities in Soil Top-Layers. [PDF]

, 2018
As two central issues of global climate change, the continuous increase of both atmospheric CO2 concentrations and global temperature has profound effects on various terrestrial ecosystems.

Increased simulated precipitation frequency promotes greenhouse gas fluxes from the soils of seasonal fallow croplands

Journal of Sustainable Agriculture and Environment, 2023
Introduction Farmlands are key sources of greenhouse gas (GHG) emissions, which are susceptible to changes in precipitation regimes. The soils of seasonal fallow contribute approximately half of annual GHG emissions from farmlands, but the effect of ...

Methane-cycling communities in a permafrost-affected soil on Herschel Island, Western Canadian Arctic: active layer profiling ofmcrAandpmoAgenes [PDF]

FEMS Microbiology Ecology, 2012
In Arctic wet tundra, microbial controls on organic matter decomposition are likely to be altered as a result of climatic disruption. Here, we present a study on the activity, diversity and vertical distribution of methane-cycling microbial communities in the active layer of wet polygonal tundra on Herschel Island.

Season and No-Till Rice Crop Intensification Affect Soil Microbial Populations Involved in CH4 and N2O Emissions

Frontiers in Soil Science, 2022
Rice is an important source of methane (CH4) and other crops may be sources of nitrous oxide (N2O), both of which are powerful greenhouse gases. In Uruguay, irrigated rice rotates with perennial pastures and allows high productivity and low environmental

Effects of nitrogen load on the function and diversity of methanotrophs in the littoral wetland of a boreal lake

Frontiers in Microbiology, 2012
Methane is the second most abundant greenhouse gas in the atmosphere. A major part of the total methane emissions from lake ecosystems are emitted from littoral wetlands. Methane emissions are significantly reduced by methanotrophs as they use methane as

Identification of Novel Methane-, Ethane-, and Propane-Oxidizing Bacteria at Marine Hydrocarbon Seeps by Stable Isotope Probing [PDF]

, 2010
Marine hydrocarbon seeps supply oil and gas to microorganisms in sediments and overlying water. We used stable isotope probing (SIP) to identify aerobic bacteria oxidizing gaseous hydrocarbons in surface sediment from the Coal Oil Point seep field ...

Nitrogen Redox Controls on Greenhouse Gas Production in Yedoma Taliks. [PDF]

Glob Chang Biol
Arctic Yedoma permafrost holds large carbon and nitrogen pools that, when thawed, undergo microbially mediated processes that release greenhouse gases like methane and nitrous oxide. We analyzed seasonal shifts in microbial community dynamics and geochemistry in deep thawed soils (talik) and found year‐round methane production, with limited winter ...
