dc.description.abstractThis study evaluates the capacity of algal propagules to survive digestion by 7 intertidal herbivore mollusks. Individual [30] Littorina peruviana, 36 of Siphonaria lessoni, 35 of Collisella ceciliana, and 25 each of C. zebrina, Chiton granosus, Fissurella crassa and F. limbata were collected at different dates between Oct., 1983 and April, 1984. About half of the individuals of each species were examined for gut contents and the other half was used to provide fecal pellets for culture. Diet of these grazers ranged from 8 macroalgal species in Collisella zebrina to 17 in F. limbata. Macroalgal propagules of 56% of the 27 algal species found in these gut contents survive digestion. There was no positive correlation between diet and number of algal taxa growing in the respective fecal cultures. Survival through L. peruviana and Chiton granosus was low (20-30% of the algal species consumed) while it was high (75-83%) through the 2 spp. of Collisella. No significant correlation was found between frequency of algae in the gut contents and its frequency in the fecal cultures. Algal capacity to survive digestion was almost exclusively restricted to opportunistic species, especially in the Chlorophyta and Phaeophyta. Survival of algal propagules through the digestive tract of generalist grazers may be a rather random phenomenon.
