The 427 analysed specimens fell into 132 multilocus genotypes (MLGs), suggesting that asexual reproduction plays an important role in the maintenance of these populations. A haploweb analysis of ITS2 sequences of each MLG was consistent with all of them being conspecific. Genetic differentiation was detected both between and within islands, but when a single sample per MLG was included in the analyses, the populations turned out to be nearly panmictic. These observations provide further evidence of the marked variability in reproductive strategies and genetic structure of P. damicornis throughout its geographic range; comparison with results previously obtained for the congeneric species Pocillopora meandrina underlines the importance of life history traits in shaping the genetic structure of coral populations. specialized POLYNESIE FRANCAISE 034 161 3 531-541 2014 0025-3162 https://www.documentation.ird.fr/hor/fdi:010061822 10.1007/s00227-013-2355-9 0025-3162 [F B010061822] https://www.documentation.ird.fr/hor/fdi:010061822 https://www.documentation.ird.fr/intranet/publi/2014/03/010061822.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-04-02 2017-08-23 fdi:010061822 fre
