Sympatry of cryptic species is of special interest to both ecologists and evolutionary biologists because the mechanisms that facilitate their persistent coexistence are obscure. In this study, we report on two sympatric <i>Dictyota</i> species, <i>D. dichotoma</i> (Huds.) J. V. Lamour. and the newly described species <i>D. cymatophila</i> sp. nov., from the Canary Islands. Gene sequence data (rbcL, psbA, nad1, cox1, cox3, and LSU rDNA) demonstrate that <i>D. dichotoma</i> and <i>D. cymatophila</i> do not represent sister species. Rather, <i>D. cymatophila</i> and <i>D. dichotoma</i> have converged on a nearly identical morphology, only to be distinguished with detailed morphometric observations. Both species co-occur in eulittoral pools and the shallow subtidal in Tenerife. Even though <i>D. cymatophila</i> was more dominant in wave-exposed places and <i>D. dichotoma</i> in less exposed areas, the spatial distribution of both species overlapped in intermediate habitats. The species display radically different phenologies. <i>D. dichotoma</i> reached its highest density in winter and early spring and disappeared nearly completely in autumn, while <i>D. cymatophila</i> dominated the study site from July until November. The timing of gamete release also differs between both species, <i>D. dichotoma</i> releasing gametes twice every lunar cycle, while the release of gametes in <i>D. cymatophila</i> occurred roughly every other day.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Niche partitioning and the coexistence of two cryptic <i>Dictyota</i> (Dictyotales, Phaeophyceae) species from the Canary Islands","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":"Canary Islands; cryptic species; Dictyota cymatophila; Dictyota dichotoma; niche partitioning; phenology; reproductive ecology","OtherDescriptors":null,"Notes":null,"AnaPub":2010,"MonPub":null,"DateUpdate":"2016-06-12","DateCreate":"2011-10-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000284854100003","VABBcode":null,"OpenAcc":0,"DOI":"10.1111/j.1529-8817.2010.00912.x"},"refs":null,"anarec":{"AnaID":208548,"PubliDate":2010,"Pagination":"1075-1087","XtraPublOfAnaID":null,"ISBN":null,"Volume":"46","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43251,"SerRR":"Journal of Phycology.
