Dissolved and Particulate Organic Carbon Characteristics in Summer and Winter Waters of the Lena Delta

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 154-166, January/March 2026.
ABSTRACT Rapid Arctic warming accelerates permafrost thaw, altering water flow and organic matter transport to aquatic ecosystems. To identify sources and seasonality of OC at the mouth of the Lena River, we measured summer and winter concentrations and C isotopes (∆14C and δ13C) of DOC and POC along a 140‐km transect of the Lena Delta.

Effects of long‐term flood irrigation and fertilization on greenhouse gas emissions and soil nitrogen in mountain hay meadows

Soil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Mountain hay meadows are a high‐elevation forage‐producing agroecosystem dependent on flood irrigation and nitrogen (N) fertilization to maintain yields, meaning management has great potential to influence greenhouse gas (GHG) emissions. To assess GHG fluxes and inorganic N dynamics in meadows, field monitoring was established at four ranches ...

Resource availability governs polyhydroxyalkanoate (PHA) accumulation and diversity of methanotrophic enrichments from wetlands

Frontiers in Bioengineering and Biotechnology, 2023
Aquatic environments account for half of global CH4 emissions, with freshwater wetlands being the most significant contributors. These CH4 fluxes can be partially offset by aerobic CH4 oxidation driven by methanotrophs.

Land Cover and Hydrology Regulate Riverine Carbon Emissions From Subarctic Catchments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Streams transport carbon (C) and nutrients across the terrestrial‐aquatic interface and are significant sources of methane (CH4) and carbon dioxide (CO2) to the atmosphere. Climate‐induced changes in vegetation and hydrology increase the export of dissolved organic carbon (DOC) from terrestrial to aquatic ecosystems, but the impact of these ...

Multiheme hydroxylamine oxidoreductases produce NO during ammonia oxidation in methanotrophs

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Methanotrophs oxidize methane to CO2, thereby mitigating the emission of this potent greenhouse gas. Understanding how these microorganisms are influenced by anthropogenic activities will help better predict their impact on global warming ...

Novel copper-containing membrane monooxygenases (CuMMOs) encoded by alkane-utilizing Betaproteobacteria. [PDF]

, 2020
Copper-containing membrane monooxygenases (CuMMOs) are encoded by xmoCAB(D) gene clusters and catalyze the oxidation of methane, ammonia, or some short-chain alkanes and alkenes.

Millimetre‐Scale Stratification of Microbial Communities in Hydrothermal Sediments

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Zooming into the millimetre‐scale spatial distribution of organic molecules in hydrothermally impacted sediments using mass spectrometry imaging reveals a distinct lipid zonation with abrupt transitions at critical redox interfaces. This zonation reflects a pronounced stratification of diverse microbial communities and highlights surprisingly ...

Thermophilic methane oxidation is widespread in Aotearoa-New Zealand geothermal fields

Frontiers in Microbiology, 2023
Geothermal areas represent substantial point sources for greenhouse gas emissions such as methane. While it is known that methanotrophic microorganisms act as a biofilter, decreasing the efflux of methane in most soils to the atmosphere, the diversity ...
