The salinity regime at the study site was highly variable, remaining mostly between 20 and 30 psu with changes over 3 psu occurring rapidly and frequently. Periodic water sampling revealed a significant inverse relationship between NO<sub>3</sub><sup>-</sup> concentration and salinity, but not between NH<sub>4</sub><sup>+</sup> concentration and salinity. Experimental changes in salinity modelled on those observed at the study site resulted in a decline in net oxygen production, while NH<sub>4</sub><sup>+</sup> and NO<sub>3</sub><sup>-</sup> uptake rates remained similar. These results suggest that <i>U. lactuca</i> maintains the ability to take up NH<sub>4</sub><sup>+</sup> and NO<sub>3</sub><sup>-</sup> under conditions of rapidly changing salinity within the salinity range tested and over the short-term scale examined in this study.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The impact of salinity fluctuations on net oxygen production and inorganic nitrogen uptake by <i>Ulva lactuca</i> (Chlorophyceae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Ulva; nitrate; ammonium; uptake; salinity; estuary; net oxygenproduction","OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2003-03-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000181681700005","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/s0304-3770(02)00193-6"},"refs":null,"anarec":{"AnaID":33276,"PubliDate":2003,"Pagination":"339-350","XtraPublOfAnaID":null,"ISBN":null,"Volume":"75","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
