Azooxanthellate? Most Hawaiian black corals contain Symbiodinium
The ecological success of shallow-water reef-building corals (Hexacorallia: Scleractinia) is framed by their intimate endosymbiosis with photosynthetic dinoflagellates in the genus Symbiodinium (zooxanthellae). In contrast, the closely related black corals (Hexacorallia: Anthipatharia) are described as azooxanthellate (lacking Symbiodinium), a trait thought to reflect their preference for low-l...
متن کاملSpecificity in communities of Symbiodinium in corals from Johnston Atoll
The diversity of endosymbiotic dinoflagellates (Symbiodinium) in corals at Johnston Atoll in the central Pacific Ocean was assessed using both the internal transcribed spacer 2 (ITS2) region of the nuclear rDNA and chloroplast 23S rDNA. More sequences were recovered from corals using the ITS2 primers than with the chloroplast 23S primers, a finding that reflects both the higher taxonomic resolu...
متن کاملMost corals may not change their symbionts
Many corals (stony corals and octocorals) rely on their symbiotic algae (zooxanthellae) for survival. Under stress, zooxanthellae are expelled, resulting in coral bleaching. The hypothesis that corals may survive climate change by exchanging algal types is shown here to be potentially applicable only to a minority of corals. Data on 442 coral species from 43 studies reveal that only a few coral...
متن کاملFirst real-time observation of transverse division in azooxanthellate scleractinian corals
Asexual reproduction is one of the most important traits in the evolutionary history of corals. No real-time observations of asexual reproduction in azooxanthellate solitary scleractinian corals have been conducted to date. Here, we describe previously unknown aspects of asexual reproduction by using Truncatoflabellum spheniscus (Family Flabellidae) based on observations of transverse division ...
متن کاملEffects of mechanical fracturing and experimental trampling on Hawaiian corals.
In situ trampling occurred under experimental conditions to quantify the differences in the responses to anthropogenic trampling in four dominant species of Hawaiian corals, Porites compressa, Porites lobata, Montipora capitata, and Pocillopora meandrina. Trampling was simulated daily for a period of nine days at which time further breakage was minimal. Forty treatment colonies produced 559 fra...
