Conversely, no studies were designed to investigate the role of competition for resources and predation in shaping crab distribution in mangroves, despite these biotic factors are recognised as key determinants for spatial patterns observed in the communities colonising rocky and sandy intertidal habitats.We studied floral and faunal assemblages in two zones of a Sri Lankan mangrove, a man-made upper intertidal level and a natural eulittoral, mid-shore one. Leaf choice experiments were designed to study both feeding rate and intra and inter-specific interactions for food of sesarmid crabs in the two habitats in order to better understand crab spatial distribution.</p>              </div><div xmlns:func=\"http://oscar.fig.bmc.com\" xmlns=\"http://www.w3.org/1999/xhtml\" class=\"AbstractSection\" id=\"ASec2\">                <h3 xmlns=\"\" class=\"Heading\">Results</h3>                <p id=\"Par2\" class=\"Para\">The two intertidal belts differed in terms of floral composition and crab species abundance. The eulittoral zone was strongly dominated by <i>Neosarmatium smithi</i>, while within the elevated littoral fringe four sesarmids (<i>N. smithi</i>, <i>N. asiaticum</i>, <i>N. malabaricum</i> and <i>Muradium tetragonum</i>) were more evenly distributed. At both levels, all sesarmids showed to collect significantly more <i>Bruguiera</i> spp. and <i>Rhizophora apiculata</i> leaves than <i>Excoecaria agallocha</i> ones. There was no temporal segregation in feeding activity among the four species, resulting in a high interference competition for leaves. Regardless of the habitat, <i>N. smithi</i> was always successful in winning inter-specific fights.</p>              </div><div xmlns:func=\"http://oscar.fig.bmc.com\" xmlns=\"http://www.w3.org/1999/xhtml\" class=\"AbstractSection\" id=\"ASec3\">                <h3 xmlns=\"\" class=\"Heading\">Conclusions</h3>                <p id=\"Par3\" class=\"Para\">Our results showed that the elevated littoral fringe was more crowded with crabs, but was less favourable in terms of food availability and environmental conditions. The dominance of <i>N. smithi</i> in gathering mangrove leaves suggests that this species may segregate the other sesarmids into less favourable habitats. The present data strongly suggest for the first time that interference competition for food can contribute to shape mangrove crab spatial distribution.</p>","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Interference competition as a key determinant for spatial distribution of mangrove crabs","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Sesarmid crabs; Aggressive behaviour; Distribution patterns;Indo-Pacific mangroves; Environmental factors","OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2018-05-23","DateCreate":"2018-05-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000425128600002","VABBcode":null,"OpenAcc":1,"DOI":"10.1186/s12898-018-0164-1"},"refs":null,"anarec":{"AnaID":295479,"PubliDate":2018,"Pagination":"8","XtraPublOfAnaID":null,"ISBN":null,"Volume":"18","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":70605,"SerRR":"BMC Ecology.
