      corals suggests potential benefits.

AB  - We investigated the occurrence of intracolonial genetic variability (IGV) in 
      Pocillopora corals in the southwestern Indian Ocean. Ninety-six colonies were 
      threefold-sampled from three sites in Reunion Island. Nubbins were genotyped 
      using 13 microsatellite loci, and their multilocus genotypes compared. Over 50% 
      of the colonies presented at least two different genotypes among their three 
      nubbins, and IGV was found abundant in all sites (from 36.7% to 58.1%). To define 
      the threshold distinguishing mosaicism from chimerism, we developed a new method 
      based on different evolution models by computing the number of different alleles 
      for the infinite allele model (IAM) and the Bruvo's distance for the stepwise 
      mutation model (SMM). Colonies were considered as chimeras if their nubbins 
      differed from more than four alleles and if the pairwise Bruvo's distance was 
      higher than 0.12. Thus 80% of the IGV colonies were mosaics and 20% chimeras 
      (representing almost 10% of the total sampling). IGV seems widespread in 
      scleractinians and beyond the disabilities of this phenomenon reported in several 
      studies, it should also bring benefits. Next steps are to identify these benefits 
      and to understand processes leading to IGV, as well as factors influencing them.
