title: Evolutionary relationships of "Candidatus endobugula" bacterial symbionts and their Bugula bryozoan hosts.
abstract: Ribosomal gene sequences were obtained from bryozoans in the genus Bugula and their bacterial symbionts; analyses of host and symbiont phylogenetic trees did not support a history of strict cospeciation. Symbiont-derived compounds known to defend host larvae from predation were only detected in two out of four symbiotic Bugula species.
