Light-Dependent Phenomena and Related Molecular Mechanisms in Giant Clam-Dinoflagellate Associations: A Review

Frontiers in Marine Science, 2021
Giant clams can grow to large sizes despite living in oligotrophic waters of the tropical Indo-Pacific as they maintain a mutualistic relationship with symbiotic dinoflagellates (zooxanthellae) and receive photosynthate from them.

Climate change promotes parasitism in a coral symbiosis. [PDF]

, 2018
Coastal oceans are increasingly eutrophic, warm and acidic through the addition of anthropogenic nitrogen and carbon, respectively. Among the most sensitive taxa to these changes are scleractinian corals, which engineer the most biodiverse ecosystems on ...

Study on expelled but viable zooxanthellae from giant clams, with an emphasis on their potential as subsequent symbiont sources.

PLoS ONE, 2019
Unlike most bivalve shellfishes, giant clams (tridacnines) harbor symbiotic microalgae (zooxanthellae) in their fleshy bodies. Zooxanthellae are not maternally inherited by tridacnine offspring, hence, the larvae must acquire zooxanthellae from external ...

Dimethylsulphoniopropionate (DMSP) as an Indicator of Bleaching Tolerance in Scleractinian Corals

Journal of Marine Science and Engineering, 2015
Thermal tolerance tests on Acropora millepora, a common Indo-Pacific hard coral, have shown that adult corals can acquire increased thermal tolerance by shuffling existing type C to type D Symbiodinium zooxanthellae when subjected to increased seawater ...

Light-Dependency of Growth and Secondary Metabolite Production in the Captive Zooxanthellate Soft Coral Sinularia flexibilis [PDF]

The branching zooxanthellate soft coral Sinularia flexibillis releases antimicrobial and toxic compounds with potential pharmaceutical importance. As photosynthesis by the symbiotic algae is vital to the host, the light-dependency of the coral, including

Global Warming and the Spread of the Introduced Jellyfish Cassiopea andromeda: Thermal Niche and Habitat Suitability in the Mediterranean Sea. [PDF]

Glob Chang Biol
Written Summary: Climate change is reshaping marine ecosystems, with the Mediterranean Sea among the most vulnerable due to warming and non‐native species such as the upside‐down jellyfish Cassiopea andromeda. We investigated the thermal tolerance and habitat suitability of its polyps, a key stage for reproduction and persistence.

Partial quantification of pigments extracted from the zooxanthellate octocoral Sinularia flexibilis at varying irradiances [PDF]

, 2010
Chlorophyll-a (chl-a) and carotenoid pigments of the zooxanthellate octocoral Sinularia flexibilis were analyzed using high performance liquid chromatography following exposure to three light intensities for over 30 days. From the coral fragments located

Genetic Population Structure and Distribution of the Small Giant Clam <i>Tridacna maxima</i> in Indo-Pacific Coral Reefs: History Dynamics, Present Status and Future Trends. [PDF]

Ecol Evol
Six distinct groups were identified in T. maxima across the Indo‐Pacific region, which was shaped by the ocean currents and the late Pleistocene glaciations. Gene‐flow analysis supported the center of origin hypothesis for the high biodiversity of the Indo‐Malay Archipelago.
