Liming pasture soils in the Amazon region promotes low-affinity methane oxidation by type I and II methanotrophs

This study shows that liming Amazonian pasture soils increases methane uptake by promoting low-affinity methane oxidation by type I and II methanotrophs.

Dynamics of methane cycling microbiome during methane flux hot moments from riparian buffer systems

The paper examines methane cycling microbial communities in riparian buffer systems during methane flux hot moments, finding that methanogen activity varies with soil type and water content.

Maintaining grass coverage increases methane uptake in Amazonian pasture soils

This study shows that maintaining grass coverage in Amazonian pasture soils increases methane uptake and reduces methane-producing microbes, while liming converts soils from methane sinks to sources.

Seasonal dynamics of methane cycling microbial communities in Amazonian floodplain sediments.

This study examines seasonal changes in methane-cycling microbial communities in Amazonian floodplain sediments, finding high methanogen abundance and diverse methanotroph pathways.

Belowground changes to community structure alter methane-cycling dynamics in Amazonia

The paper measures methane flux and microbial communities across land use changes in Amazonia, finding that pasture soils emit methane while forests act as sinks, with microbial shifts driving these changes.

Rainforest-to-pasture conversion stimulates soil methanogenesis across the Brazilian Amazon

This study shows that converting rainforest to pasture in the Brazilian Amazon increases soil methanogenesis, with pastures acting as methane sources and secondary rainforests as sinks.
