Ebullition Dominates Methane Fluxes From The Water Surface Across Different Ecohydrological Patches In A Temperate Freshwater Marsh At The End Of The Growing Season
Villa, J. A., Ju, Y., Yazbeck, T., Waldo, S., Wrighton, K. C., Bohrer, G.

Measurements of the spatial heterogeneity of methane fluxes in wetlands are critical to better understand and predict methane emissions at the ecosystem scale. However, the within-wetland spatial heterogeneity of fluxes is rarely assessed. Here, we use a spatially balanced rapid chamber-based survey of methane at different ecohydrological …

Plant‐Mediated Methane Transport In Emergent And Floating‐Leaved Species Of A Temperate Freshwater Mineral‐Soil Wetland
Villa, J. A., Ju, Y., Stephen, T., Rey‐Sanchez, C., Wrighton, K. C., Bohrer, G.

Methane flux from freshwater mineral-soil (FWMS) wetlands and its variability among sites is largely modulated by plant-mediated transport. However, plant-mediated transport processes are rarely resolved in land surface models and are poorly parametrized for plants commonly found in FWMS wetlands. Here, relationships between methane …

Relationships Between Methane and Carbon Dioxide Fluxes in a Temperate Cattail‐Dominated Freshwater Wetland
Villa, J., Ju, Y., Vines, C., Rey-Sanchez, C., Morin, T.H., Wrighton, K.C., Bohrer, G.

Wetlands are the most important natural source of methane (CH4) to the atmosphere, and there is still considerable uncertainty of CH4 flux and net carbon budgets of wetlands. This uncertainty is due in part to the complex role of wetland vegetation in controlling methane production, oxidation and transport, which challenge the modeling …

Members of the genus Methylobacter are inferred to account for the majority of aerobic methane oxidation in oxic soils from a freshwater wetland
Smith, G. J., Angle, J. C., Solden, L. M., Borton, M. A., Morin, T. H., Daly, R. A., Johnston, M. D., Stefanik, K. C., Wolfe, R., Bohrer, G., Wrighton, K. C.

Microbial carbon degradation and methanogenesis in wetland soils
generate a large proportion of atmospheric methane, a highly potent greenhouse
gas. Despite their potential to mitigate greenhouse gas emissions, knowledge about
methane-consuming methanotrophs is often limited to lower-resolution single-gene
surveys that fail to …

Methanogenesis In Oxygenated Soils Is A Substantial Fraction Of Wetland Methane Emissions
Angle, J. C., Morin, T. H., Solden, L. M., Narrowe, A. B., Smith, G. J., Borton, M. A., Rey-Sanchez, C., Daly, R. A., Mirfenderesgi, G., Hoyt, D. W., Riley, W. J., Miller, C. S., Bohrer, G., Wrighton, K. C.

The current paradigm, widely incorporated in soil biogeochemical models, is that microbial methanogenesis can only occur in anoxic habitats. In contrast, here we show clear geochemical and biological evidence for methane production in well-oxygenated soils of a freshwater wetland. A comparison of oxic to anoxic soils reveal up to …

Determining Total Emissions And Environmental Drivers Of Methane Flux In A Lake Erie Estuarine Marsh
Rey-Sanchez, A., Morin, T., Stefanik, K., Wrighton, K., Bohrer, G.

Estuarine freshwater marshes can act as an important ecosystem for carbon storage and flux because of its strategic position in a watershed. We monitored CH4and CO2 fluxes in Old Woman Creek, an estuarine wetland of Lake Erie, Ohio. The eddy covariance (EC) technique was used to measure fluxes of CH4 and CO2 continuously during the …
