Photosynthesis and photoprotection in symbiotic corals
In zooxanthellate corals, excess excitation energy can be dissipated as heat (nonphotochemical quenching), thereby providing protection against oxidative damage by supraoptimal light in shallow reefs. To identify and quantify the photoprotective mechanisms, we studied the diel variability of chlorophyll fluorescence yields and photosynthetic parameters in situ in corals, using moored and SCUBA-...
متن کاملInteractions between Corals and their Symbiotic Algae
Interactions between Corals and their Symbiotic Algae Gisèle Muller-Parker and Christopher F. D'Elia The mutualistic relationship between corals and their algal endosymbionts is a key factor in the evolutionary success of hermatypic (reef building) corals. Corals that harbor endosymbiotic algae exhibit faster rates of calcification, photoautotrophy and many other attributes that are believed to...
متن کاملGrowth rates of three symbiotic corals in the Red Sea
Growth rates of the hydrocoral Millepora dichotoma and the corals Acropora variabilis and Stylophora pistillata were studied by applying the buoyant weighing technique and statistical analysis. We found that M. dichotoma exhibited the slowest relative growth, whereas S. pistillata and A. variabilis were faster growers, with weight-based doubling times of about 3, 1.2, and 1.3 yr, respectively. ...
متن کاملIsolation of actin-encoding cDNAs from symbiotic corals.
A cDNA (named LGfact) encoding actin was identified in planular larvae of the scleractinian coral Galaxea fascicularis, using the reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) techniques. RNA from the adult coral that was inhabited by symbiotic dinophytes was subjected to a similar RT-PCR, and a cDNA fragment, named AGfact-p, was found to e...
متن کاملCorals form characteristic associations with symbiotic nitrogen-fixing bacteria.
The complex symbiotic relationship between corals and their dinoflagellate partner Symbiodinium is believed to be sustained through close associations with mutualistic bacterial communities, though little is known about coral associations with bacterial groups able to fix nitrogen (diazotrophs). In this study, we investigated the diversity of diazotrophic bacterial communities associated with t...
