Light intensity and herbivory are two major factors which affect plants' physiology and population dynamics. Corallina pilulifera, is a turf-forming red alga which is often dominant in rocky intertidal and subtidal shores. In the study site in southeast kyushu, C. pilulifera demonstrated a wide range of colour variation in fronds, which appeared to result from the variation of light availability. The accumulation of pigment would affect the growth of the alga through the process of photosynthesis. Hermit crabs also seem to affect the dynamics of algal population, by cutting their fronds and removing the sediment accumulated beneath the algae. The former action generates a negative effect on algal growth, while the latter generates a positive effect. Thus, in this study we investigated (1) the relationship between light intensity, colour variation and growth, and (2) the effect of hermit crabs on the algal population. An attempt was made to experimentally manipulate sedimental removal, frond cutting and crab density.

Self-thinning and size-density relationships in a natural mangrove forest dominated by Kandelia candel, were studied from June to October 2004. A belt-transect plot of 100 m long and 5 m wide (an area of 500 m²), running through a river-land gradient, was established. Subplots were established at every 5 m (a total of 20 subplots). Size parameters of individual trees including tree height (H), stem diameter at 10% height (D_0.1), crown width (R) and height of the lowest living leaves (H_L) were measured. Crown depth (C_d), coverage (C), crown volume (C_v) and tree weight (w) were calculated. The mean tree density varied from 4.9 trees m^-2 near the river bank to 2.7 trees m^-2 near the land. Size parameters were influenced by tree density and also related to the distance from the river to the land. The biomass shows an increase from the river to the land, representing the various stages of growth and development of this forest. The slope of the self-thinning line for this mangrove forest stand was ca. -1.3.
