Suspended organic matter in the mangrove channels was more depleted in <sup>13</sup>C (average d<sup>13</sup>C = –24.5‰) than in Kakinada bay which showed d<sup>13</sup>C values for suspended matter (average d<sup>13</sup>C = –22.7‰) closer to those expected for marine phytoplankton. Suspended organic matter from mangrove channels was enriched in nitrogen (average C/N atom ratio = 12.7) and <sup>13</sup>C (average d<sup>13</sup>C = –24.5‰) relative to mangrove leaf litter, which had a C/N ratio of 75 and a d<sup>13</sup>C value of –28‰. Lowest C/N ratios for suspended matter were observed during southwest monsoon when rainfall was highest. Although in general, mangrove litter fall was also lower during this period, no clear correlation was observed between litter fall and C/N ratio of suspended matter. In general, the composition of suspended matter pointed towards phytoplankton as a major component. Isotopic composition of zooplankton suggested selective feeding on <sup>13</sup>C-enriched, marine phytoplankton in open Kakinada bay and on <sup>13</sup>C-depleted organic matter, such as estuarine phytoplankton and mangrove litter, in the mangrove channels. From the d<sup>13</sup>C signature, it appeared that mangrove carbon was present to some extent in zooplankton and macrofauna from the mangrove mudflats and channels, but the signal rapidly decreased in Kakinada bay. Nitrogen isotopic composition of zooplankton and macrofauna indicated a progressive enrichment of <sup>15</sup>N away from the mangrove forest towards the northern part of Kakinada bay, in approach of Kakinada city. This is thought to reflect input of anthropogenic nitrogen enriched in <sup>15</sup>N and subsequent uptake of this enriched nitrogen into the aquatic food chain.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Tracing mangrove carbon in suspended matter and aquatic fauna of the Guatami-Godavari Delta, Bay of Bengal (India)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"stable isotope tracers; carbon; nitrogen; mangroves; litterfall; suspended matter; zooplankton; macrobenthos","OtherDescriptors":null,"Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2019-07-02","DateCreate":"2001-05-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000089348000012","VABBcode":null,"OpenAcc":0,"DOI":"10.1023/A:1004072310525"},"refs":null,"anarec":{"AnaID":10293,"PubliDate":2000,"Pagination":"225-241","XtraPublOfAnaID":null,"ISBN":null,"Volume":"431","Issue":"2-3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42943,"SerRR":"Hydrobiologia.
