Table 2. Composition of genotype for ITS-rDNA sequences and monophyletic clades for psbAncr sequences of Symbiodiniaceae from Palythoa species used in this study and microenvironments of host habitats.
Significances were tested by Fisher’s Exact Test and V value represents Cramer’s coefficient of association.

Notes.
P. aff. mutuki was removed from statistical analyses of psbAncr region due to low numbers of specimens.
