Sampling was carried out in concomitance with the first record of <i>Siganus luridus</i> in Linosa and fish were caught simultaneously, allowing direct comparison of diets. Gut-contents analyses provided a snapshot of the feeding habits of the three species: <i>Siganus luridus</i> fed on 34 taxa of benthic algae (mostly represented by <i>Dictyota dichotoma</i>) and a total of 27 taxa was identified in the stomach of <i>Sarpa salpa</i>, with the predominance of <i>Sargassum vulgare</i>. For the first time, a detailed picture of <i>Sparisoma cretense</i> diet was given (N=22 taxa of identified algae) albeit, due to the high percentage of digested food, this species was excluded from gut-content comparisons. A certain resource partitioning between <i>Siganus luridus</i> and <i>Sarpa salpa</i> was resolved on the basis of trophic indices and multivariate analyses, these latter also highlighting a more dispersed diet for <i>Siganus luridus</i> with respect to <i>Sarpa salpa</i>. Isotopic signatures were important towards defining the trophic level of the three species and particularly of <i>Sparisoma cretense</i>, whose gut-contents analysis was only partially informative. The values of d<sup>15</sup>N confirmed a strictly vegetal diet for <i>Siganus luridus</i> and <i>Sparisoma cretense</i> while <i>Sarpa salpa</i> was significantly more enriched. According to d<sup>13</sup>C, observed values matched the predicted ones for <i>Siganus luridus</i> and <i>Sarpa salpa</i> while both species presented less enriched d<sup>15</sup>N values than expected.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Resource partitioning among early colonizing <i>Siganus luridus</i> and native herbivorous fish in the Mediterranean: an integrated study based on gut-content analysis and stable isotope signatures","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-11 01:31:36.862954","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2007,"MonPub":null,"DateUpdate":"2020-10-26","DateCreate":"2007-12-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000249347900024","VABBcode":null,"OpenAcc":0,"DOI":"10.1017/S0025315407056342"},"refs":null,"anarec":{"AnaID":117553,"PubliDate":2007,"Pagination":"991-998","XtraPublOfAnaID":null,"ISBN":null,"Volume":"87","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43277,"SerRR":"Journal of the Marine Biological Association of the United Kingdom.
