Abstract
The seasonal cycle for standing crop and chlorophyll content of Thalassia testudinum and its epiphytes is described from monitoring data collected at a study site in Santa Rosa Sound, northwestern Florida, from December 1983 through March 1987. Water temperature correlated more highly with standing crop and chlorophyll measurements than did salinity or incident light. The seasonal cycle described for Thalassia was positively correlated with temperature whereas epiphyte standing crop was negatively correlated with water temperature. These findings are compared with other reports on seasonality of Thalassia growth.
