Environmental Controls on Corallite Morphology in the Reef Coral Montastraea Annularis
Scleractinian reef-coral species display high phenotypic plasticity in skeletal morphology. Understanding environmental and physiologic controls on this variation is essential to explaining the distribution and abundance of coral species as well as understanding their susceptibility to pollution and global climate change. Here we assess phenotypic plasticity in the corallite morphology of genet...
متن کاملInfluence of thermal history on the response of Montastraea annularis to short-term temperature exposure
Acclimation of reef corals to environmental conditions has been related to metabolic response at large geographic scales, but regional relationships have rarely been described. Physiological responses to temperature increases of Montastraea annularis (Ellis and Solander 1786) from an inner lagoon and an outer barrier reef in the Gulf of Honduras, southern Belize, were compared in May 2003. The ...
متن کاملEnvironmental factors affecting tissue regeneration of the reef--building coral Montastraea annularis (Faviidae) at Los Roques National Park, Venezuela.
In this study, the rates of tissue regeneration and recovery from injuries that emulated the bites of either butterfly or parrotfish on colonies of Montastraea annularis exposed to different sedimentation regimesp were determined. Two small reef patches were chosen close to key Dos Mosquises, north of the Venezuclan mainland. Sixteen colonies (8 treatments + a single replicate) were artificiall...
متن کاملBiological Responses of the Coral Montastraea annularis to the Removal of Filamentous Turf Algae
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 beginn...
متن کاملMicrobial to reef scale interactions between the reef-building coral Montastraea annularis and benthic algae.
Competition between reef-building corals and benthic algae is of key importance for reef dynamics. These interactions occur on many spatial scales, ranging from chemical to regional. Using microprobes, 16S rDNA pyrosequencing and underwater surveys, we examined the interactions between the reef-building coral Montastraea annularis and four types of benthic algae. The macroalgae Dictyota bartayr...
