Species-level controls of foliar methane and nitrous oxide fluxes: roles of traits and microbes in temperate trees. [PDF]

New Phytol
Species‐level variation in temperate tree foliar greenhouse gas exchange, showing consistent foliar CH4 uptake, N2O emission, stronger CH4 uptake in fall leaves, and contrasting methanotroph communities between the high‐CH4‐oxidizing species Tilia americana and the low‐CH4‐oxidizing species Prunus virginiana. Summary The contribution of tree foliage to

Testing the efficacy of surface swab sampling to determine postmortem submersion interval (PMSI), using the microbiome colonization of skeletal remains. [PDF]

J Forensic Sci
Abstract Postmortem interval (PMI) estimation contributes valuable information in the medicolegal investigation of decomposed human remains, and estimating the postmortem submersion interval (PMSI) can specifically aid investigations involving victims discovered in aquatic environments.

Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub-Arctic Waterbodies in Northern Canada. [PDF]

Environ Microbiol
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Enhancement of Nitrous Oxide Emissions in Soil Microbial Consortia via Copper Competition between Proteobacterial Methanotrophs and Denitrifiers. [PDF]

Appl Environ Microbiol, 2021
Unique means of copper scavenging have been identified in proteobacterial methanotrophs, particularly the use of methanobactin, a novel ribosomally synthesized, post-translationally modified polypeptide that binds copper with very high affinity.

The water column of the Yamal tundra lakes as a microbial filter preventing methane emission [PDF]

Biogeosciences, 2021
Microbiological, molecular ecological, biogeochemical, and isotope geochemical research was carried out in four lakes of the central part of the Yamal Peninsula in the area of continuous permafrost. Two of them were large (73.6 and 118.6 ha) and deep (up

Active Methanotrophs and Their Response to Temperature in Marine Environments: An Experimental Study

Journal of Marine Science and Engineering, 2021
Aerobic methane (CH4) oxidation plays a significant role in marine CH4 consumption. Temperature changes resulting from, for example, global warming, have been suggested to be able to influence methanotrophic communities and their CH4 oxidation capacity ...

Microbial Communities Drive Methane Fluxes From Floodplain Lakes-A Hydrological Gradient Perspective. [PDF]

Environ Microbiol
This study examined the impact of methanotrophic bacteria (MOB) and methanogenic archaea (mGen) on CH4 emissions from oxbow lakes at various successional stages, analysing their interactions with physicochemical properties of water. The microbial structure, defined by the MOB/mGen ratio, shows emission rates of CH4 specific to each oxbow type.

Redox Zone and Trophic State as Drivers of Methane-Oxidizing Bacterial Abundance and Community Structure in Lake Sediments

Frontiers in Environmental Science, 2022
Eutrophication is expected to increase methane production in freshwater sediments worldwide over the coming decades. Methane-oxidizing bacteria (MOB) consume a significant fraction of this sedimentary methane, but the factors that control their ...

Microbial epibiotic community of the deep-sea galatheid squat lobster Munidopsis alvisca

Scientific Reports, 2022
Life at hydrothermal vent sites is based on chemosynthetic primary producers that supply heterotrophic microorganisms with substrates and generate biomass for higher trophic levels.

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 ...
