DOI	10.17600/93000020
Objective	Study of the benthos on isolated oceanic sites: correlation between larval dispersal (planktotrophic or non-planktotrophic), colonization capacity and speciation. The model site for this study was North East Atlantic seamounts, making a varied ensemble in terms of age, size and relative distance.
