Species composition and percent cover were determined at 5 rn intervals along the transects using a canopy-coverage technique originally developed for tercestrial systems (Daubenmire 1968). Four seagrass species were found as weIl as one attached algae. The overall frequency of occurrence for each species indicated the following dominance:<i> Halodule wrightii </i>(71.9%), <i>Ruppia maritima </i>(23.7% ), <i>Syringodium filiforme </i>(9.4% ),<i> Halophila engelmannii </i>(2.3% ), and <i>Caulerpa prolifera</i> (5.4% ).<i> Halodule wrightii</i> and <i>R. maritima</i> were represented on most transects.<i> S .filiforme</i> was never encountered on 14 of 37 transects and, when it occurred, the most frequently recorded percent coverage was < 5%. Temporal trends in percent cover for <i>Halodule wrightii</i> indicate a significant long-term decline.<i> R. maritima</i> maintained an average occurcence of 26% and cover of 6% from 1983 to 1989. These averages dropped to 11% occurrence and 1.2% percent cover for 1990-1994. A marked increase occurred in 1995-1996 when occurrence was 49% and percent cover was 19%. The increase in<i> R. maritima </i>and declines in<i> S. filiforme</i> and <i>Halodule wrightii</i> appear to be linked to recent declines in salinity. An increase in the number of bare plots was also observed over the study.<i> C. prolifera</i> was observed in remarkably high coverages from 1986 to 1987, but rapidly declined by 1989. These data provide benchmarks that will be useful to researchers and managers in comparing trends observed elsewhere in the lagoon and determining if these are site-specific or regional trends.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Long-term trends in seagrass beds in the Mosquito lagoon and Northern Banana River, Florida","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-08 01:30:37.424245","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2001-05-22","DateCreate":"2001-05-10","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":8764,"PubliDate":2000,"Pagination":"177-193","XtraPublOfAnaID":null,"ISBN":"0-8493-2045-3","Volume":"16","Issue":null,"BRefMon":8750,"BRefMonRR":"<b>Bortone, S.A.
