Recruitment of Ascophyllum Nodosum: Wave Action as a Source of Mortality
The brown alga Ascophyllum nodosum is a dominant rocky intertidal organism throughout much of the North Atlantic Ocean, yet its inability to colonize exposed or denuded shores is well recognized. Our experimental data show that wave action is a major source of mortality to recently settled zygotes....
