Substrate deposit effect on the characteristic of an intertidal macroalgal community

摘要

Present study consists the effect of substrate deposit (silt, clay, sand, gravel and shards of shells) on the characteristic of an intertidal rocky shore macroalgae. Macroalgal assemblage was segregated from substrate deposit in two stages. Substrate deposit was subsequently quantified. Silt and sand-shell combine were the major constituent of the substrate deposit. Subsequent results showed that the characteristic of the intertidal macroalgal assemblages are influenced both positively and negatively. Species richness was high in a station with high clay substrate deposit. Substrate deposit as a whole, thus, has a functional role and has an influencing role which can cause a characteristic change on the macroalgal diversity of intertidal rocky shore ecosystem.
