A Stable Association of the Stress-Tolerant Zooxanthellae, Symbiodinium Clade D, with the Low-Temperature-Tolerant Coral, Oulastrea crispata (Scleractinia: Faviidae) in Subtropical Non-Reefal Coral Communities
並列摘要
We examined spatial and temporal zooxanthellae diversity in a low-temperature-tolerant coral, Oulastrea crispata, from 2 subtropical non-reefal coral communities, the Penghu Islands (the Pescadores), Taiwan and from Hong Kong, China using restriction fragment length polymorphism (RFLP) of partial nuclear small subunit ribosomal DNA (nssrDNA) and large subunit ribosomal DNA (nlsrDNA), together with phylogenetic analyses of DNA sequences. Oulastrea crispata occurs commonly on shallow reef depressions and on turbid bay bedrock inhabited by only a few other corals, and is a pioneer coral colonizing artificial substrates where environmental disturbance is high. This study demonstrates that the zooxanthellae associated with O. crispata, in Penghu and in Hong Kong belong to Symbiodinium clade D, a clade of zooxanthellae formally proposed to be stress tolerant in marginal habitats (Toller et al. 2001a). Analyses of zooxanthellae diversity showed no apparent symbiosis polymorphism on either a spatial or temporal scale, suggesting that the association with Symbiodinium clade D is stable in O. crispata. Oulastrea crispata possesses opportunistic life history traits, including a variety of reproductive strategies and physiological tolerances, enabling it to colonize a variety of substrata unfavorable to other corals. Our finding showed a stable association with a stress-tolerant symbiont which may provide a key to how O. crispata can achieve such physiological adaptability.
