Abstract
Brown algae are important residents of intertidal ecosystems like New Bedford Harbor of Massachusetts. Release of industrial waste has left this habitat high in metals and polychlorinated biphenyls, and the effects of exposure on coastal macroalgae are poorly understood. To determine whether chronic contaminant exposure affects offspring development, embryogenesis was evaluated in three populations of Fucus vesiculosus from sites of varying contamination. While the time to germination was unaffected, cytokinesis was delayed and growth was retarded in embryos from the more contaminated sites. A pulse exposure of polychlorinated biphenyls at fertilization did not affect early growth parameters.
