Photomosaic as a conservation and analysis tool: These images are formed from 2,500-3,500 individual images. The analysis of the mosaics has led to the discovery that coral colonies on Palmyra’s reed are arranged in a non-random way and that corals tend to be clustered together according to the reef landscape and the cluster’s specific growth and reproductive strategy used by a given coral.
