The agent responsible for these symptoms, <i>Labyrinthula zosterae</i>, was present in these three sites; its infestation was highly correlated with leaf-age. To distinguish the periods of increased <i>Labyrinthula</i> infestation from the periods of normal functioning of the plant with none or only few infestations, a procedure based on the association of a wasting index (WI) and leaf-age was developed. This procedure is capable of revealing the phases of early infestation and recession of the `disease' by comparison of the normal infestation of <i>Labyrinthula</i> which develops only to a minor extent in the oldest leaves of the shoots. The overall seasonal dynamics of leaf production and leaf growth were masked by the local conditions of each <i>Zostera bed</i>. Over the period of study (1-2 years), no significant mortality due to<i> Labyrinthula</i> was observed. The variability of the WI appeared to depend essentially on the normal life-span of the leaves and local events, and appeared to be asynchronous. However, periods of `disease' were observed; in which the WI increased from 5-10% (baseline) to 20-25% (maximum) at the end of the summer, when the leaf surface and leaf numbers were at their maximum. No die-off due to <i>Labyrinthula</i> was found.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Spatio-temporal variability of wasting disease symptoms in eelgrass meadows of Brittany (France)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"<i>Zostera marina</i>; Wasting disease; <i>Labyrinthula zosterae</i>; Spatio-temporal variability; Meadow dynamics","Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2003-03-10","DateCreate":"2003-03-10","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000174175200004","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":33035,"PubliDate":2002,"Pagination":"37-53","XtraPublOfAnaID":null,"ISBN":null,"Volume":"72","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
