Spatial and Temporal Patterns in Nitrous Oxide Flux from Agricultural Soil in Southern Ontario
This research examines spatial and temporal variations in N2O flux from agricultural clay loam in corn-wheat and corn-oat rotations in southern Ontario. Gas samples are collected by the chamberExpand
Short-term effects of thinning on soil CO2, N2O and CH4 fluxes in Mediterranean forest ecosystems.
Soil temperature resulted as the main driving variable for CO2 efflux and CH4 uptake and N2O fluxes, and GHG fluxes showed significant correlations with C and N content of both forest floor and mineral soil, especially in the deepest layers, suggesting that it should be considered, together with environmental variables, when accounting GHGs fluxes in degraded forests.

Clostridiaceae and Enterobacteriaceae as active fermenters in earthworm gut content
It is shown that Clostridiaceae and Enterobacteriaceae (fermentative subsets of these taxa) are selectively stimulated by glucose and might therefore be capable of consuming mucus- and plant-derived saccharides during gut passage and indicate that ingested obligate anaerobes and facultative aerobes from soil can concomitantly metabolize the same source of carbon.

In Situ Hydrogen and Nitrous Oxide as Indicators of Concomitant Fermentation and Denitrification in the Alimentary Canal of the Earthworm Lumbricus terrestris
The findings suggest that earthworms contribute to the terrestrial cycling of carbon and nitrogen via anaerobic microbial activities in the alimentary canal and constitute a mobile source of reductant for microbiota in aerated soils. Expand
Workshop on Agricultural Air Quality Concurrent Measurement of Litter Gas Flux and Nutrients with Air and Litter Properties in Poultry Houses to Improve Emission Estimates
Introduction Emissions of dust, gases and odors from poultry facilities pose major challenges for the poultry industry. In addition to environmental issues associated with air and water quality,Expand
Short-term effects of clearfelling on soil CO2, CH4, and N2O fluxes in a Sitka spruce plantation
Abstract We examined the effects of forest clearfelling on the fluxes of soil CO 2 , CH 4 , and N 2 O in a Sitka spruce ( Picea sitchensis (Bong.) Carr.) plantation on an organic-rich peaty gleyExpand
In Situ Analysis of Structure and Activity of the Nitrifying Community in Biofilms, Aggregates, and Sediments
This review summarizes the state of microscale in situ analyses of nitrification and potential, limitations, and future perspectives of such combined microsensor/FISH approaches for the study ofNitrification are discussed. Expand
The Earthworm Gut: an Ideal Habitat for Ingested N2O-Producing Microorganisms
The hypothesis that the in situ conditions of the earthworm gut activate ingested N2O-producing soil bacteria during gut passage is supported, and a combination of supplements yielded rates greater than that obtained mathematically for single supplements, suggesting that the maximum rates observed were due to synergistic effects of supplements.
