Heterotrophic microbial communities use ancient carbon following glacial retreat
When glaciers retreat they expose barren substrates that become colonized by organisms, beginning the process of primary succession. Recent studies reveal that heterotrophic microbial communitiesExpand

Abiotic drivers and plant traits explain landscape-scale patterns in soil microbial communities.
The controls on aboveground community composition and diversity have been extensively studied, but our understanding of the drivers of belowground microbial communities is relatively lacking, despiteExpand

Assessment of Odours from Livestock Wastes by a Photoionization Detector, an Electronic Nose, Olfactometry and Gas Chromatography-Mass Spectrometry
Abstract A photoionization detector (PID) and an electronic nose (EN) based on polypyrrole sensors, were evaluated against odour concentration measurement by olfactometry using odours from pig andExpand

Production and Emission of Odours and Gases from Ageing Pig Waste
Emission rates of gases and compounds that cause odour (odorants) and their cumulative odour as perceived by a sensory panel were determined over a 112 d storage period for pig slurry. Emission ratesExpand

Reduction of Odorous Compounds in Fresh Pig Slurry by Dietary Control of Crude Protein
Two diets containing reduced levels of crude protein for both growing (35-65 kg) and finishing (65-95 kg) pigs were tested against standard commercial diets to determine changes in the odorantsExpand
