The biomass and primary production of a <i>C. nodosa</i> meadow located at a depth of 8–11 m was estimated at the time of maximum annual vegetative development (summer) using reconstruction techniques, and compared with those available from shallow meadows of this species. A depth-referenced data base of values at the time of maximum annual development was compiled to that end. The vegetative development of <i>C. nodosa</i> at 8–11 m depth was not different from that achieved by shallow (depth <3 m) meadows of this species. Only shoot density, which decreased from 1637 to 605 shoots m<sup>−2</sup>, and the annual rate of elongation of the horizontal rhizome, which increased from 23 to 71 cm apex<sup>−1</sup> year<sup>−1</sup>, were different as depth increased from <3 to 8–11 m. Depth was a poor predictor of the vegetative development and primary production of <i>C. nodosa</i>. The biomass of rhizomes and roots decreased with depth (g DW m<sup>−2</sup> = 480 (±53, S.E.) − 32 (±15, S.E.) depth (in m); <i>R</i><sup>2</sup> = 0.12, <i>F</i> = 4.65, d.f. = 35, <i>P</i> = 0.0381) which made total biomass of the meadow to show a trend of decrease with depth but the variance of biomass data explained by depth was low. The annual rate of elongation of the horizontal rhizome showed a significant positive relationship with depth (cm apex<sup>−1</sup> year<sup>−1</sup> = 18 (±5.1, S.E.) + 5.0 (±1.33, S.E.) depth (in m); <i>R</i><sup>2</sup> = 0.50, <i>F</i> = 14.07, d.f. = 14, <i>P</i> = 0.0021). As shoot size and growth did not change significantly with depth, the reduction of shoot density should drive any changes of biomass and productivity of <i>C. nodosa</i> as depth increases. The processes by which this reduction of <i>C. nodosa</i> abundance with depth occur remain to be elucidated.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Biomass and primary production of a 8-11 m depth meadow versus <3 m depth meadows of the seagrass <i>Cymodocea nodosa</i> (Ucria) Ascherson","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:31.598284","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"seagrass; Cymodocea nodosa; depth gradient; biomass; shoot density;primary production; Mediterranean Sea","OtherDescriptors":null,"Notes":null,"AnaPub":2006,"MonPub":null,"DateUpdate":"2020-10-19","DateCreate":"2006-04-26","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000236617300007","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquabot.2005.12.004"},"refs":null,"anarec":{"AnaID":98318,"PubliDate":2006,"Pagination":"324-332","XtraPublOfAnaID":null,"ISBN":null,"Volume":"84","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
