Abstract: Gigartina papillata (Rhodophyta) cultured in high concentrations of NO3, NH4 and guano for 10 days showed the same changes in R-phycoerythrin for all three conditions. G. papillata from an area with high guano exposure off China Point on the Monterey Peninsula showed significantly (p < .01) more phycoerythrin and significantly (p < .05) less carrageenan than control sites with little guano exposure. G. papillata was also shown to be significantly (p < .01) thicker in distal branches than in control sites. Endocladia muricata (Rhodophyta) and G. papillata from high guano density areas were shown significantly (p < .01) shorter and had significantly (p < .01) less branching than did the same species in control sites.
