Genetic diversification and life-cycle of the polychaete Capitella spp. from the English Channel: evidence for sympatric cryptic species and alternative reproductive strategies
International audience Polychaetes belonging to the genus Capitella are known to represent a complex of opportunistic cryptic species that dominates the macrobenthos of organically enriched sediments, such as muddy areas particularly rich in sulfide. With the exception of the species, Capitella capi...
