Journal ArticleDOI
Damage to photosystem II in symbiotic dinoflagellates: A determinant of coral bleaching
TL;DR: Temperature-dependent loss of PSII activity and concomitant decrease in D1 reaction center protein seen in symbionts collected from corals naturally bleached on the reef are confirmed, indicating that perturbation ofPSII protein turnover rates during photoinhibition at elevated temperatures underlies the physiological collapse of symbiont in corals susceptible to heat-induced bleaching.
Journal ArticleDOI
Low symbiont diversity in southern Great Barrier Reef corals, relative to those of the Caribbean
Todd C. LaJeunesse,William K. W. Loh,Robert van Woesik,Ove Hoegh-Guldberg,Gregory W. Schmidt,William K. Fitt +5 more
TL;DR: The comparison of symbiont diversity between southern GBR and Caribbean reefs shows an inverse relationship between coral diversity and symbionT diversity, perhaps as a consequence of more-rapid diversification of Caribbean symbionts.
Journal ArticleDOI
The effects of elevated temperature on the photosynthetic efficiency of zooxanthellae in hospite from four different species of reef coral: a novel approach
TL;DR: Fundamental differences in the physiology of the symbionts within different species of coral are identified, with zooxanthellae within M. annularis appear to be more susceptible to heat-induced damage at or near the reaction centre of Photosystem II, while zooxanhellae living in S. radians remain capable of dissipating excess excitation energy through non-photochemical pathways, thereby protecting the photosystem from damage during heat exposure.
Journal ArticleDOI
Multi-year, seasonal genotypic surveys of coral-algal symbioses reveal prevalent stability or post-bleaching reversion
Daniel J. Thornhill,Todd C. LaJeunesse,Todd C. LaJeunesse,Dustin W. Kemp,William K. Fitt,Gregory W. Schmidt +5 more
TL;DR: The extent to which coral colonies show fluctuations in their associations with different endosymbiotic dinoflagellates is documents, and the exposure to greater environmental variability near the surface may explain the higher symbiont diversity found within and between host colonies.
