Macrocystis pyrifera

Tin concentrations in algae collected near the Scripps Institution of Oceanography, Calif, and in coastal marine sediments from Narragansett Bay, USA, were determined by Hodge and coworkers42. Tin concentrations of the blades of Pelagophycus porra, Macrocystis pyrifera and Eisenia arborea were 0.71 0.01, 0.83 0.01 and 1.06 0.02 i-gSng 1 dry wt., respectively. Tin concentrations in the core of sediments are shown in Table 8.

Spores of the kelps Macrocystis pyrifera and Pterygophora califomica are stimulated to settle more rapidly by the presence of nutrient mixtures but the behavior is only observed five or more hours after they are released (Amsler and Neushul 1990).
