Photosynthetic planulae and planktonic hydroids: contrasting strategies of propagule survival

Scientia Marina, 2000
Settlement delays can be important to prevent propagule waste when proper settling substrates are not immediately available. Under laboratory conditions, the planulae of Clytia viridicans underwent two alternative developmental patterns.

Using Transcript Levels of Nitrate Transporter 2 as Molecular Indicators to Estimate the Potentials of Nitrate Transport in Symbiodinium, Cladocopium, and Durusdinium of the Fluted Giant Clam, Tridacna squamosa

Frontiers in Marine Science, 2021
Giant clams are important ecosystem engineers of coral reefs because they harbor large quantities of phototrophic Symbiodiniaceae dinoflagellates of mainly genera Symbiodinium, Cladocopium, and Durusdinium.

Light intensity, photoperiod duration, daily light flux and coral growth of Galaxea fascicularis in an aquarium setting: a matter of photons? [PDF]

, 2012
Light is one of the most important abiotic factors influencing the (skeletal) growth of scleractinian corals. Light stimulates coral growth by the process of light-enhanced calcification, which is mediated by zooxanthellar photosynthesis.

Carbonic anhydrase 2‐like in the giant clam, Tridacna squamosa: characterization, localization, response to light, and possible role in the transport of inorganic carbon from the host to its symbionts

Physiological Reports, 2017
The fluted giant clam, Tridacna squamosa, lives in symbiosis with zooxanthellae which reside extracellularly inside a tubular system. Zooxanthellae fix inorganic carbon (Ci) during insolation and donate photosynthate to the host.

Effects of trace metal concentrations on the growth of the coral endosymbiont Symbiodinium kawagutii

Frontiers in Microbiology, 2016
Symbiodinium is an indispensable endosymbiont in corals and the most important primary producer in coral reef ecosystems. During the past decades, coral bleaching attributed to the disruption of the symbiosis has frequently occurred resulting in ...

Biogeographical Patterns of Coral‐Associated Symbiodiniaceae Across Thermal Regimes Including Trace Molecular Detection of Cladocopium thermophilum (C3‐Gulf) in the Seychelles

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Reef‐building corals rely on symbiotic dinoflagellates (Symbiodiniaceae) for survival; however, the distribution of thermotolerant symbionts across environmental gradients remains poorly understood. Using ITS2 metabarcoding across three bioregions spanning extreme to moderate thermal regimes (Bahrain, Seychelles, and Indonesia), we show that ...

Negative response of photosynthesis to natural and projected high seawater temperatures estimated by pulse amplitude modulation fluorometry in a temperate coral

Frontiers in Physiology, 2015
Balanophyllia europaea is a shallow water solitary zooxanthellate coral, endemic to the Mediterranean Sea. Extensive field studies across a latitudinal temperature gradient highlight detrimental effects of rising temperatures on its growth, demography ...

Symbiotic Dinoflagellates of the Giant Clam, Tridacna squamosa, Express Ammonium Transporter 2 at the Plasma Membrane and Increase Its Expression Levels During Illumination

Frontiers in Marine Science, 2022
Giant clams harbor dinoflagellates generally of the three genera (Symbiodinium, Cladocopium, and Durusdinium) of phototrophic Symbiodiniaceae. Coccoid dinoflagellates (alias zooxanthellae) are found mainly inside zooxanthellal tubules located in the ...

Even a slight temperature increase triggers the inhibition of Symbiodiniaceae cell division and promotes cell expulsion in the coral Acropora selago

Phycological Research, Volume 74, Issue 3, Page 224-233, July 2026.
SUMMARY Coral bleaching, characterized by the loss of Symbiodiniaceae symbionts from corals, is promoted both by acute high‐temperature events and by prolonged moderate thermal stress. However, the mechanisms responsible for decreases in Symbiodiniaceae cell densities within corals remain unclear. Symbiodiniaceae cells within corals proliferate through
