This study utilized the acetylene inhibition technique to estimate the relative importance of denitrification in nitrogen removal from a primarily ombrotrophic peatland, in an attempt to estimate the threat of increased nitrogen loadings to these areas. Estimates of mean rates of denitrification ranged from \u22122.76 to 84.0 ng N<jats:sub>2<\/jats:sub>O\u2010N cm<jats:sup>\u22123<\/jats:sup> h<jats:sup>\u22121<\/jats:sup> (equivalent to \u2212150 to 4800 \u03bcg N<jats:sub>2<\/jats:sub>O\u2010N m<jats:sup>\u22122<\/jats:sup> h<jats:sup>\u22121<\/jats:sup>) using an ex situ core technique and from \u22128.30 to 5.98 \u03bcg N<jats:sub>2<\/jats:sub>O\u2010N m<jats:sup>\u22122<\/jats:sup> h<jats:sup>\u22121<\/jats:sup> using an in situ chamber technique. Core rates may have been elevated over natural field levels due to effects of disturbance on substrate availability, and chamber rates may have been low due to diffusional constraints on acetylene and N<jats:sub>2<\/jats:sub>O. Net nitrification was also measured in an attempt to evaluate this process as a source of nitrate for denitrifiers. The low rates of net nitrification measured, in combination with the low rates of in situ denitrification and the very low amounts of free nitrate measured in this peatland, suggests that inorganic N turnover in this wetland is low. Results showed that nitrate was a limiting factor for denitrification in this peatland, with mean rates from nitrate\u2010amended cores ranging from 13.1 to 260 ng N<jats:sub>2<\/jats:sub>O\u2010N cm<jats:sup>\u22123<\/jats:sup> h<jats:sup>\u22121<\/jats:sup>, and it is expected that increases in nitrogen loadings will increase denitrification rates in this ecosystem.<\/jats:p>","DOI":"10.2134\/jeq2004.0449","type":"journal-article","created":{"date-parts":[[2005,10,12]],"date-time":"2005-10-12T20:25:27Z","timestamp":1129148727000},"page":"2052-2061","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Denitrification as a Nitrogen Removal Mechanism in a Vermont Peatland"],"prefix":"10.1002","volume":"34","author":[{"given":"Melissa J.","family":"Hayden","sequence":"first","affiliation":[{"name":"Department of Plant and Soil Science University of Vermont Burlington VT 05405"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donald S.","family":"Ross","sequence":"additional","affiliation":[{"name":"Department of Plant and Soil Science University of Vermont Burlington VT 05405"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,11]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4612-2844-8_1"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1071\/SR99009"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.mi.33.100179.001521"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1029\/GL003i012p00739"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/00103628509367626"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1029\/94JD00218"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/0038-0717(94)90232-1"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.57.12.3600-3604.1991"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0038-0717(00)00247-9"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1139\/x99-148"},{"key":"e_1_2_6_12_1","first-page":"135","volume-title":"Advances in microbial ecology","author":"Focht D.D.","year":"1977"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.2136\/sssaj1984.03615995004800060002x"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1021\/es9604673"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq1998.00472425002700010021x"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02383235"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/0038-0717(89)90053-9"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1097\/00010694-198507000-00005"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq1994.00472425002300050011x"},{"key":"e_1_2_6_20_1","doi-asserted-by":"crossref","first-page":"59","DOI":"10.2136\/sssaspecpub18","volume-title":"Field measurement of dinitrogen fixation and denitrification","author":"Hauck R.D.","year":"1986"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-334910-1.50007-8"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1080\/00103629209368633"},{"key":"e_1_2_6_23_1","doi-asserted-by":"publisher","DOI":"10.2307\/1937333"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0038-0717(97)00010-2"},{"key":"e_1_2_6_25_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq1996.00472425002500040014x"},{"key":"e_1_2_6_26_1","doi-asserted-by":"crossref","first-page":"2020","DOI":"10.2134\/jeq2000.00472425002900060040x","article-title":"Denitrification rates predicted by nitrogen\u201015 labeled nitrate microcosm studies, in situ measurements, and modeling","volume":"29","author":"Hoffman C.C.","year":"2000","journal-title":"J.
