As coastal ecosystems are especially impacted by elevated nitrogen, we investigated controls on N<sub>2</sub>O production mechanisms in intertidal sediments using novel isotopic approaches and microsensors in flow-through incubations. Here we show that during incubations with elevated nitrate, increased N<sub>2</sub>O fluxes are not mediated by direct bacterial activity, but instead are largely catalysed by fungal denitrification and/or abiotic reactions (e.g., chemodenitrification). Results of these incubations shed new light on nitrogen cycling complexity and possible factors underlying variability of N<sub>2</sub>O fluxes, driven in part by fungal respiration and/or iron redox cycling. As both processes exhibit N<sub>2</sub>O yields typically far greater than direct bacterial production, these results emphasize their possibly substantial, yet widely overlooked, role in N<sub>2</sub>O fluxes, especially in redox-dynamic sediments of coastal ecosystems.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Evidence for fungal and chemodenitrification based N<sub>2</sub>O flux from nitrogen impacted coastal sediments","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-24 01:31:45.511473","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-06-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000402751400001","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/ncomms15595"},"refs":null,"anarec":{"AnaID":285987,"PubliDate":2017,"Pagination":"11 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"15595 ","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":198717,"SerRR":"Nature Communications.
