Genotypic diversity and spatial-temporal distribution of Symbiodinium clones in an abundant reef coral.

ABSTRACT: Genetic data are rapidly advancing our understanding of various biological systems including the ecology and evolution of coral-algal symbioses. The fine-scale interactions between individual genotypes of host and symbiont remain largely unstudied and constitute a major gap in knowledge. By applying microsatellite markers developed for both host and symbiont, we investigated the intracolony diversity, prevalence and stability of Symbiodinium glynni (type D1) multilocus genotypes in association with dense populations of Pocillopora at two sites in the Gulf of California. The genetic diversity and allelic frequencies in reef populations of S. glynni remained stable over 3 years. Common clone genotypes persisted over this period, and no temporal population subdivision (Φ(PT) = 0.021 and -0.00
