Large heterozygote deficiencies occurred in almost all populations, which may be related to possible self-fertilisation and short dispersal distance of zygotes. There was a high genetic differentiation among samples (Fst=0.5269***) and this was correlated with a gradient of hydrodynamic conditions prevailing on French Polynesian coral reefs. This correlation is tentatively associated with balancing selection acting on, or on the vicinity of, this anonymous DNA locus. specialized anonymous DNA locus balancing selection French Polynesia hydrodynamics Turbinaria ornata POLYNESIE FRANCAISE HAWAII SALOMON WALLIS ET FUTUNA REUNION 034 53 2 189-192 2010 0006-8055 https://www.documentation.ird.fr/hor/fdi:010084464 10.1515/bot.2010.021 0006-8055 https://www.documentation.ird.fr/hor/fdi:010084464 https://www.documentation.ird.fr/intranet/publi/2022-03/010084464.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2010-05-03 2022-03-08 fdi:010084464 fre
