Table 4. Main characteristics of Montastraea cavernosa and Xestospongia muta population at the 11 Saba Bank sites.
All values for densities and signs of stress are based on image analysis of 50 m2 transect surveys at each site and do not correspond to the samples collected for genetic analyses. (n) number of M. cavernosa and X. muta; densities per square meter; percentage of M. cavernosa colonies with tissue loss and overgrowth; and percentage of X. muta with cyclic bleaching or Sponge Orange Band Disease (SOB [49]). No disease was detected in any of the recorded M. cavernosa colonies.
