Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Hydrological controls on denitrification in riparian ecosystems [PDF]

open access: yesHydrology and Earth System Sciences, 2004
Nitrous oxide fluxes and denitrification rates were measured in situ over a year at a riparian site in the UK. An exponential relationship was found between denitrification rates and soil moisture, with a sharp increase in denitrification rate at a ...

The anaerobic soil volume as a controlling factor of denitrification: a review

open access: yesBiology and Fertility of Soils
Denitrification is an important component of the nitrogen cycle in soil, returning reactive nitrogen to the atmosphere. Denitrification activity is often concentrated spatially in anoxic microsites and temporally in ephemeral events, which presents a ...

Investigation of NO reduction mechanism of nitrogen-impregnated biomass across wide temperature range

open access: yesFuel Processing Technology
Traditional denitrification methods for coal-fired power boilers face challenges like reduced flue gas temperature at low loads, decreased efficiency of existing denitrification devices, and increased ammonia consumption.

Warming can boost denitrification disproportionately due to altered oxygen dynamics. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: Global warming and the alteration of the global nitrogen cycle are major anthropogenic threats to the environment. Denitrification, the biological conversion of nitrate to gaseous nitrogen, removes a substantial fraction of the nitrogen from ...

Nitrogen removal in a two-chambered microbial fuel cell: Establishment of a nitrifying-denitrifying microbial community on an intermittent aerated cathode [PDF]

open access: yes, 2016
A microbial fuel cell (MFC) was used to study nitrogen dynamics and its feasibility for high strength wastewater treatment. Intermittent aeration was applied on the cathode chamber accomplishing the establishment of a simultaneous nitrifying-denitrifying

Denitrification pathways and rates in the sandy sediments of the Georgia continental shelf, USA

open access: yesGeochemical Transactions, 2005
Denitrification in continental shelf sediments has been estimated to be a significant sink of oceanic fixed nitrogen (N). The significance and mechanisms of denitrification in organic-poor sands, which comprise 70% of continental shelf sediments, are ...
