Biological Responses of the Coral Montastraea annularis to the Removal of Filamentous Turf Algae

Abstract: Coral reef degradation increases coral interactions with filamentous turf algae (FTA) and macroalgae, which may result in chronic stress for the corals. We evaluated the effects of short (2.5 month) and long (10 month) periods of FTA removal on tissue thickness (TT), zooxanthellae density (ZD), mitotic index (MI), and concentration of chlorophyll a (Chl a) in Montastraea annularis at the beginning and end of gametogenesis. Ramets (individual lobes within a colony) consistently surrounded by FTA and ramets surr… Show more

“…Two types of settings for algal-coral interactions were observed in Orbicella annularis at the study site: ramets surrounded by FTA and ramets bordered by CCA (see Figs. 1A and 1B in [ 32 ]).…”

“…The FTA removal consisted of manually clearing (with the aid of a knife and wire brushes) an algal belt of ~3 cm width around the entire coral tissue periphery (> 40 cm) of the ramets (see Fig. 1C in [ 32 ]). The manual removal of FTA could have detrimental effects (damaging coral tissue).…”
