Freshwater reservoirs are an important source of the greenhouse gas methane (CH 4).
However, little is known about the activity and structure of microbial communities involved in …

Methane hydrate found in marine sediments is thought to contain gigaton quantities of
methane and is considered an important potential fuel source and climate-forcing agent …

ABSTRACT In the Sonora Margin cold seep ecosystems (Gulf of California), sediments
underlying microbial mats harbor high biogenic methane concentrations, fueling various …

Methanotrophs are ubiquitous in soil, fresh water and the open ocean, but have not been
well characterized in deep-sea hydrocarbon seeps and gas hydrates, where methane is …

Widespread conversion of coastal wetlands into aquaculture ponds in coastal region often
results in degradation of the wetland ecosystems, but its effects on sediment's potential to …

Studies on methanogenesis from freshwater sediments have so far primarily focused on lake
sediments. To expand our knowledge on the community composition of methanogenic …

Methane vents are of significant geochemical and ecological importance. Notable progress
has been made toward understanding anaerobic methane oxidation in marine sediments; …

Methane is the simplest hydrocarbon and a potent greenhouse gas that plays important
roles in atmospheric chemistry, the global carbon cycle, and the formation of gas hydrates in …

In coastal aquatic ecosystems, prokaryotic communities play an important role in regulating
the cycling of nutrients and greenhouse gases. In the coastal zone, estuaries are complex …

Methane concentrations can be high in coastal groundwater, resulting in methane export
driven by submarine groundwater discharge. However, the magnitude of this methane flux …
