Zooxanthellae population density and physiological state of the coral Stylophora pistillata during starvation and osmotic shockSymbiosis, 28
Photoacclimation dynamics to bright light was studied in the symbiotic reef-building coral Stylophora pistillata. Coral colonies were collected from shallow shaded sites (2 m, 40–20% PARs) from a fringing reef at Sesoko Island, Okinawa, Japan. Outer branches were broken off from the colonies and placed in an outdoor aquarium until the start of the experiments. After maintenance of the branches in an aquarium under a light intensity of 30% PARs for 30 days (experiment 1) or for 90 days (experiment 2), the samples were exposed to 95% PARs for 120 days in the same aquarium. The population density of zooxanthellae, chlorophyll concentration, locations of zooxanthellae, proliferating zooxanthellae frequency (PZF), and degrading zooxanthellae frequency (DZF) were examined. It was shown that after acclimation of coral branches to bright light, the population density of zooxanthellae, chlorophyll concentration calculated per 1000 polyps, and chlorophyll concentration in zooxanthellae decreased. The size of zooxanthellae significantly decreased. A decrease in the population density of zooxanthellae was detected by the eighth day of acclimation, and stabilization in the density of the symbionts occurred in the period from the 40th to the 60th day of the experiment. The chlorophyll concentration in zooxanthellae significantly decreased by the second day of exposure to bright light and stabilized by the fourth day. The PZF level sharply dropped on the second day, while the DZF level sharply increased and was higher than the PZF level for 40 days of exposure to bright light. We conclude, therefore, that the population density of zooxanthellae is regulated by the rates of two processes: cell division and the cell degradation.
