Diversity and spatial pattern of coral communities in the Red Sea upper twilight zone

  title={Diversity and spatial pattern of coral communities in the Red Sea upper twilight zone},
  author={Heiko Fricke and Bernd Knauer},
This is the first study based on numerical analysis of the abundance of 11 scleractinian corals of depths at between 100–210 m in the Red Sea twilight zone. Two distinct coral communities were found: a Leptoseris fragilis community at a depth of 100–130 m (zone 1) and a Dendrophillia horsti community below 130 m (zone 2, 3). Population densities and coral coverage are very low; distribution of individuals is highly clumped. Highest observed densities on 100 m2 were 2720 individuals for L… CONTINUE READING
