Nitrogen fixation in the mucus of Red Sea corals.
Scleractinian corals are essential constituents of tropical reef ecological diversity. They live in close association with diazotrophs [dinitrogen (N2)-fixing microbes], which can fix high rates of N2. Whether corals benefit from this extrinsic nitrogen source is still under debate. Until now, N2 fixation rates have been indirectly estimated using the acetylene reduction assay, which does not p...
متن کاملSeasonality of N2 fixation and nifH gene diversity in the Gulf of Aqaba (Red Sea)
Nitrogen (N2) fixation rates were determined on bulk water collected in the Gulf of Aqaba, Red Sea, during fall (stratified, oligotrophic) and spring (deep mixing, mesotrophic) seasons. N2 fixation rates were low yet consistently measurable in both seasons, and maximum rates of 1.0 6 0.1 nmol N L21 d21 and 1.9 6 0.2 nmol N L21 d21 occurred in the fall and spring, respectively. Amendment with in...
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 کاملFirst biological measurements of deep-sea corals from the Red Sea
It is usually assumed that metabolic constraints restrict deep-sea corals to cold-water habitats, with 'deep-sea' and 'cold-water' corals often used as synonymous. Here we report on the first measurements of biological characters of deep-sea corals from the central Red Sea, where they occur at temperatures exceeding 20°C in highly oligotrophic and oxygen-limited waters. Low respiration rates, l...
