Induction of metamorphosis of larval Phragmatopoma californica by increased external potassium. The percentage of larvae metamorphosed was scored at 24 h (•), and 48 h (A) of continuous exposure. Data are averages of four replicates, with standard deviations indicated by vertical bars. In parallel incubations, tube material produced by conspecific adults induced 60 (±28) % and 70 (±42) % of the larvae to metamorphose by 24 h and 48 h, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
