Leaves were collected from five main mangrove species: <i>Avicennia marina, Bruguiera gymnorrhiza, Ceriops tagal, Rhizophora mucronata and Xylocarpus granatum</i> occurring at Gazi Creek on the East Coast of Kenya. They were analyzed for the determination of organic Carbon, Nitrogen contents and inter- and intraspecific variations among the five species. Statistical analysis of the data has shown that the five species differ significantly in C:N ratios. C:N ratios are, <i>Avicennia</i> 28±5, <i>Bruguiera</i> 76±8.9, <i>Ceriops</i> 74±4, <i>Rhizophora</i> and <i>Xylocarpus</i> 38±7. A field experiment with litter bags was also initiated to study the decomposition of yellow, senescent leaves of <i>Ceriops tagal</i> for 1, 3, 6, 9 and 15 days. A 16% loss in the dry weight after 15 days of decomposition was observed in <i>Ceriops</i>. C:N ratio in <i>Ceriops</i> leaves has changed from 74 (fresh leaves) to 219 in senescent leaves (leaves which are about to fall) showing nitrogen resorption of 69% by the tree. The need for further research on nitrogen fixation, production, leaching, decomposition and export rates of mangrove litter is stressed. Mangrove litter, together with seagrasses and algae, could be a source of nutrient rich organic matter for the lagoon and coastal ecosystems.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"A contribution to the study of carbon and nitrogen fluxes in a kenyan mangrove ecosystem","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:58:19.190595","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":1991,"DateUpdate":"2013-03-26","DateCreate":"2013-03-26","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":224028,"ISBN":null,"PubliDate":1991,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"47","Place":"Brussel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":"MSc","ThesisID":224028,"InsID":null,"Acronym":null,"FullStandardName":null,"ToPubliDate":null,"SerNotes":null,"eISBN":null,"Pages":47},"serrec":null,"relations":null,"relationsRev":null,"addrec":null,"othpubs":null,"ownerships":null,"authors":[{"AutName":"Rao","Firstname":"Raghavendra","Initials":"R.
