DOI: 10.1007/s13157-018-0993-x
Abstract: Methane (CH4) and carbon dioxide (CO2) are greenhouse gases (GHG) important in the carbon cycle that exchanges carbon between ecosystems and the atmosphere. To determine how rice paddy fields and temperature affect the carbon budget,… read more here.

DOI: 10.1016/j.palaeo.2019.109562
Abstract: Abstract Wetland sediments archive information about past terrestrial ecosystem change including variations in fire occurrence and terrestrial carbon fluxes. The charcoal content of sediments is important for understanding past fire regimes, as well as the… read more here.

DOI: 10.1016/j.watres.2021.116958
Abstract: Methane (CH4) and nitrous oxide (N2O) are the most powerful greenhouse gases globally; recent emissions exceed previous estimates. The potential link between N2O reduction and CH4 oxidation in anoxic wetland sediments would be a sink… read more here.

DOI: 10.1021/acs.est.2c06234
Abstract: The thawing of dormant plateau permafrost emits nitrous oxide (N2O) through wetlands; however, the N2O production mechanism in plateau wetlands is still unclear. Here, we used the 15N-18O double tracer technique and metagenomic sequencing to… read more here.

DOI: 10.1093/femsec/fix089
Abstract: A Winogradsky column is a miniature ecosystem established with enriched sediments that can be used to study the relationship between biogeochemical gradients, microbial diversity and pollutant transformation. Biogeochemical processes and microbial communities changed with time… read more here.
