Here, we aimed to determine the effects of isolation-by-distance and host species on the spatial structure of sponge-associated bacterial communities using as a model the abundant demosponge genus Ircinia. We targeted three co-occurring Ircinia species and used terminal restriction fragment length polymorphism (T-RFLP) analysis of 16S rRNA gene sequences to explore the differentiation of their bacterial communities across a scale of hundreds of kilometres in the Western Mediterranean Sea. Multivariate analysis and nonmetric multidimensional scaling plots of T-RFLP profiles showed that bacterial communities in Ircinia sponges were structured by host species and remained stable across sampling locations, despite geographic distances (80–800 km) and diverse local conditions. While significant differences among some locations were observed in Ircinia variabilis-derived communities, no correlation between geographic distance and community similarity was consistently detected for symbiotic bacteria in any host sponge species. Our results indicate that bacterial communities are mostly shaped by host species-specific factors and suggest that evolutionary processes acting on longterm symbiotic relationships have favored spatial stability of sponge-associated bacterial communities.This research was funded by the Spanish Government projects CTM2010-17755 and CTM2010- 22218, the Catalan Government grant 2009SGR-484 for Consolidated Research Groups, the US National Science Foundation under grant 0853089, and a FI-DGR fellowship to L.P.Peer reviewedBlackwell Publishing201320132013info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/84872reponame:DIGITAL.CSIC.
