Spartina Alterniflora in Two New Brunswick Salt Marshes. II. Potential Use by Littorina Saxatalis
Littorina saxatalis, common to two New Brunswick marshes, did not discriminate between living leaves produced late or early in the season, and preferred dead over living leaf material. Its gut extract was able to release sugar from several structural polysaccharides as well as from S. alterniflora leaf powder. It was more active toward living than toward dead leaf material, and was not inhibited by ferulic acid. From field observations we conclude that the bulk of Spartina detritus will not become available to potential macroconsumers during the year of its production. In the Bay of Fundy marsh, it will be widely dispersed in the open water by tidal currents; in the Northumberland marsh, much of its subsequent decay will occur within the marsh.
