Abstract

This study investigated the potential for methylotrophic methanogenesis in three Sphagnum-dominated peatland soils in northern Minnesota. Collected soils were amended with 13C-labeled traditional substrates (acetate and sodium bicarbonate/ H2) and methylated substrates (methanol, monomethylamine (“MMA”), dimethylsulfide (“DMS”)) and monitored for δ13C-CH4, δ 13C-CO2, and net CH4 and CO2 production in laboratory incubations. The peatlands included in the study were (1) the S1 Bog, home to the SPRUCE Experiment and located at the Marcell Experimental Forest (MEF, U.S. Forest Service), (2) Bog Lake Fen, also located at the MEF, and (3) Zim Bog. These sites have been described in detail previously (Medvedeff et al., 2015)

SPRUCE Deep Peat Microbial Diversity, CO2 and CH4 Production in Response to Nutrient, Temperature, and pH Treatments during Incubation Studies.

Dataset A., Kluber Laurel ; Allen, Samantha A. ; Hendershot, Nicholas ; ...

This data set contains the results of a microcosm incubation study on deep peat collected from the SPRUCE experimental site in the S1 Bog in September 2014. Microcosms were monitored for CO2 and CH4 production, and microbial community dynamics were assessed using qPCR and amplicon sequencing.The experiment was designed with a full factorial design with elevated temperature, nitrogen (N), (P), and pH treatments was used with samples from each transect serving replicates. In all, 96 microcosms were constructed to account for the 16 treatment combinations (N x P x pH x temperature), 2 time points, and 3 replicates. Temperature treatmentsmore »« less
SPRUCE Small Differences in Ombrotrophy Control Regional-Scale Variation in Methane Cycling among Sphagnum-Dominated Peatlands: Supporting Data

Dataset Zalman, C. ; Keller, J.K. ; Tfaily, M. ; ...

These data are provided in support of the SPRUCE publication: Small Differences in Ombrotrophy Control Regional-Scale Variation in Methane Cycling among Sphagnum-Dominated Peatlands (Zalman et al., 2018) Reports the examination of the mechanisms controlling C cycling rates and greenhouse gas emissions using a combination of biogeochemical and microbial approaches in three low pH, Sphagnum-dominated peatlands in northern Minnesota. In particular, we investigated biogeochemical parameters (CH4 and CO2 production potentials, porewater and gas CH4 and CO2 concentrations and associated isotopic signatures), soil chemistry (organic acids and phenolics), and microbial community characteristics (quantification of methanogen and methanotroph abundance and activity) over amore »« less
CO2 and CH4 Production and CH4 Oxidation in Low Temperature Soil Incubations from Flat- and High-Centered Polygons, Utqiagvik (Barrow), Alaska, 2012

Dataset Zheng, Jianqiu ; RoyChowdhury, Taniya ; Graham, David

The dataset consists of respiration and methane production rates and methane oxidation potential obtained from soil microcosm studies carried out under controlled temperature and incubation conditions. Soils cores collected in 2012 represent the flat- and high-centered polygon active layers and permafrost (when present) from the NGEE Arctic Intensive Study Site 1, Barrow, Alaska. Data presented here will improve our understanding of the temperature controls on the temporal variation in microbially mediated carbon loss potentials from soils impacted by a characteristic microtopographic feature in the Arctic tundra ecosystems. Such an understanding will in turn help parameterize fine-scale models that constrain soilmore »« less
