Royle growing in two submerged beds in southwest Thailand. The N and P concentrations and δ15N decreased with increasing distance along the leaf. The maximum ranges in one leaf were 1.80-4.05% for N, 2.85-6.64 mg g-1 for P, and 1.28-2.93pm for δ15N. The C:N, C:P, and N:P ratios increased as the distance along the leaf increased. The maximum ranges in one leaf were 12.5-24.3 for C:N, 162-622 for C:P, and 14.0-28.9 for N:P. In contrast, C concentration and δ13C fluctuated with distance along the leaf, and the longest leaves from each beds showed similar patterns of fluctuation. The variation of the chemical signature within leaves suggests that special attention is needed to apply these data to the evaluation of nutrient conditions during growth in food-web analyses involving seagrass beds.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Internal variations in nutrient concentrations and the C and N stable isotope ratios in leaves of the seagrass <i>Enhalus acoroides</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-09 01:31:11.858330","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"carbon nitrogen; phosphorus; delta C-13; delta N-15; resorption;Thailand","OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2020-09-16","DateCreate":"2004-05-14","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000221313300008","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquabot.2004.01.007"},"refs":null,"anarec":{"AnaID":61474,"PubliDate":2004,"Pagination":"95-102","XtraPublOfAnaID":null,"ISBN":null,"Volume":"79","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
