Anaerobic Metabolism in Tidal Freshwater Wetlands: I. Plant Removal Effects on Iron Reduction and Methanogenesis

Jason K. Keller, Auteur ; Ariana E. Sutton-Grier, Auteur ; Allyson L. Bullock, Auteur ; J. Patrick Megonigal, Auteur

Dans Estuaries and Coasts (36(3) MAY 2013)

For energetic reasons, iron reduction suppresses methanogenesis in tidal freshwater wetlands; however, when iron reduction is limited by iron oxide availability, methanogenesis dominates anaerobic carbon mineralization. Plants can mediate this m[...]

Anaerobic Metabolism in Tidal Freshwater Wetlands: II. Effects of Plant Removal on Archaeal Microbial Communities

David Emerson, Auteur ; Wendy Bellows, Auteur ; Jason K. Keller, Auteur ; Craig L. Moyer, Auteur ; Ariana Sutton-Grier, Auteur ; J. Patrick Megonigal, Auteur

Dans Estuaries and Coasts (36(3) MAY 2013)

The interaction of plant and microbial communities are known to influence the dynamics of methane emission in wetlands. Plant manipulations were conducted in an organic rich (JB-organic) and a mineral rich (JB-mineral) site in a tidal freshwater[...]

Anaerobic Metabolism in Tidal Freshwater Wetlands: III. Temperature Regulation of Iron Cycling

Allyson L. Bullock, Auteur ; Ariana E. Sutton-Grier, Auteur ; J. Patrick Megonigal, Auteur

Dans Estuaries and Coasts (36(3) MAY 2013)

Understanding the ecological processes that regulate the production and fate of methane (CH4) in wetland soils is essential for forecasting wetland CH4 emissions. Iron reduction is an important carbon mineralization pathway that is capable of su[...]
