Effects of interactive global changes on methane uptake in an annual grassland. [PDF]

, 2010
The future size of the terrestrial methane (CH4) sink of upland soils remains uncertain, along with potential feedbacks to global warming. Much of the uncertainty lies in our lack of knowledge about potential interactive effects of multiple ...

Dense bottom gravity currents and their impact on pelagic methanotrophy at oxic/anoxic transition zones [PDF]

, 2016
We show that inflows of oxygenated waters into sulfidic layers have a strong impact on biogeochemical transformation at oxic/anoxic transition zones. Taking the pelagic methane dynamics in the Gotland Basin as an example, we performed our studies when ...

Morphological constraints on plant‐mediated methane release and oxidation under experimental warming in a peatland and meadow on the Qinghai‐Tibetan Plateau

Functional Ecology, Volume 39, Issue 12, Page 3571-3585, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Alpine meadows and peatlands on the Qinghai‐Tibetan Plateau, respectively, act as sinks and sources of atmospheric CH4. Yet, little is known about plant‐mediated CH4 fluxes in these ecosystems.

A metagenomics-based metabolic model of nitrate-dependent anaerobic oxidation of methane by Methanoperedens-like archaea

Frontiers in Microbiology, 2015
Methane oxidation is an important process to mitigate the emission of the greenhouse gas methane and further exacerbating of climate forcing. Both aerobic and anaerobic microorganisms have been reported to catalyze methane oxidation with only a few ...

Plant community structure mediates potential methane production and potential iron reduction in wetland mesocosms. [PDF]

, 2013
Wetlands are the largest natural source of methane to the atmosphere, but factors controlling methane emissions from wetlands are a major source of uncertainty in greenhouse gas budgets and projections of future climate change.

Origin and temporal variability of unusually low δ13C-DOC values in two High Arctic catchments [PDF]

, 2016
The stable carbon isotopic composition of dissolved organic matter (δ13C-DOC) reveals information about its source and extent of biological processing. Here we report the lowest δ13C-DOC values (−43.8‰) measured to date in surface waters.

The Effect of Nitrogen Enrichment on C1-Cycling Microorganisms and Methane Flux in Salt Marsh Sediments

Frontiers in Microbiology, 2012
Methane (CH4) flux from ecosystems is driven by C1-cycling microorganisms – the methanogens and the methylotrophs. Little is understood about what regulates these communities, complicating predictions about how global change drivers such as nitrogen ...

Consumption of Methane and CO_2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea [PDF]

, 2007
The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor.

The incredible lightness of being methane-fuelled : stable isotopes reveal alternative energy pathways in aquatic ecosystems and beyond [PDF]

, 2016
We have known about the processes of methanogenesis and methanotrophy for over 100 years, since the days of Winogradsky, yet their contributions to the carbon cycle were deemed to be of negligible importance for the majority of that period. It is only in
