The diets of juvenile (mm) Syngnathus scovelli and of Hippocampus zosterae, abundant members of a resident fish community in a Thalassia testudnum seagrass bed in Tampa Bay, Florida, were examined from Apnl to October 1984. Harpacticoid copepods comprised most of the diet, both in terms of percent number and percent biomass, for the smaller size classes of S. scovelli and for H. zosterae, and harpacticoids generally had the highest index of relative importance (IRI) for both syngnathids. S. scovelli displayed ontogenetic switching to larger food items, such as amphipods, shrimp and crustacean eggs. Harpacticus sp. 1 was the …

Dynamics of the aboveground and belowground structure of the seagrass Halodule wrightii (Asherson) Asherson was studied from April 1984 to March 1985. Seasonality of plant structure was evident, with the highest abundance of short shoots and belowground structures occurring in June. An Inverse relationship between root and rhizome biomass was observed with the former reaching a maximum in February and March, while the latter attained highest values in July and August. The number of short shoots produced per branch varied over the year, ranging from a low of 0.4 to a high of 1.5. The ratio number of branches/rhizome length …
