Title:Plant-mediated root methane emissions and oxidation in a thermokarst bog complex in the Bonanza Creek LTER Experimental Forest IV - Oxic and Anoxic Methane Fluxes on Isolated Carex Plants 2015
Alternate Identifier:DOI PLACE HOLDER
Abstract:

Vascular plants are important in the wetland methane cycle but their effect on production, oxidation, and transport has high uncertainty, limiting our ability to predict emissions. Vegetation operated on top of baseline methane emissions, which varied with proximity to the thawing permafrost margin. Emissions from vegetated plots increased over the season, resulting in cumulative seasonal methane emissions that were 4.1-5.2 g m-2 season-1 greater than unvegetated plots. Mass balance calculations signify these greater emissions were due to increased methane production (3.0-3.5 g m-2 season-1) and decreased methane oxidation (1.1-1.6 g m-2 season-1). Minimal oxidation occurred along the plant-transport pathway and oxidation was suppressed outside the plant pathway. Our data indicate suppression of methane oxidation was stimulated by root exudates fueling competition among microbes for electron acceptors. Root exudates are known to fuel methane production and our work provides evidence they also decrease methane oxidation. This dataset contains 2015 monthly methane fluxes from isolated Carex plants in a bog complex in the Bonanza Creek LTER. Isolated plant fluxes were used to partition the flux from the plant mediated pathway.

Description:

Experimental Design

Over the summer season of 2015 we measured methane emissions from different vegetation treatments to understand the affect of vegetation on the methane cycle.

Methods

FIELD: Anaerobic control fluxes were done to verify darkness in anaerobic flux did not affect results. These fluxes mimicked anearobic fluxes but instead of the nitrogen flush, the chamber was placed askew on the collar, enabling oxygenation of the system while keeping it in the dark. LAB: Methane flux samples were analyzed within 24 hours using Varian 3800 gas chromatograph with an FID detector with a Haysep N column (Varian Analytical Inc., Palo Alto, CA, USA). Emission rates were defined as the fitted linear slope of methane concentrations through time, excluding poor fits (r2<0.8).
