High rates of ammonium regeneration were measured in the two communities at the end of summer (296.03 ± 40.07 and 201.7 ± 62.74 μmolN m<sup>−2</sup> h<sup>−1</sup>, respectively) as well as high respiration rates (2.60 ± 0.94 and 2.23 ± 0.59 mmolC m<sup>−2</sup> h<sup>−1</sup>, respectively). Significant benthic gross primary production (up to 6.11 mmolC m<sup>−2</sup> h<sup>−1</sup>) was measured in the muddy sand community but no benthic primary production was measured in the fine-sand community. It suggests that microphytobenthic production values used in simulations previously published for these two communities were overestimated while values of community respiration were underestimated. The study confirms that this benthic system is heterotrophic and strengthens the idea that an important pelagic-benthic coupling is required for the functioning in such coastal ecosystems.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Benthic primary production, respiration and remineralisation: in situ measurements in the soft-bottom <i>Abra alba</i> community of the western English Channel (North Brittany)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-04 01:30:54.695307","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"sediment-water interface; carbon dioxide exchange; ammonia; benthic;respiration rates; primary production; English Channel","OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2020-10-07","DateCreate":"2005-06-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000228965700002","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":73318,"PubliDate":2005,"Pagination":"223-229","XtraPublOfAnaID":null,"ISBN":null,"Volume":"53","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43261,"SerRR":"Journal of Sea Research.
