ON THE FEEDING REACTIONS AND DIGESTION IN THE CORAL POLYP ASTRANGIA DANÆ, WITH NOTES ON ITS SYMBIOSIS WITH ZOÖXANTHELLÆ

, 1925
The feeding reactions of Astrangia in general consist of four actions: muscular action of the tentacles, muscular action of the central part of the oral disk, secretion of mucus by the oral disk, and ciliary action of the stomodaeum.The reaction of the ...

Marine Heatwaves Transform Coral Symbioses With Enduring Effects

Ecology Letters, Volume 28, Issue 11, November 2025.
Marine heatwaves are disrupting coral–algal symbioses, yet their long‐term effects remain poorly understood. Using a decade‐long survey (2013–2023), we document a lasting transformation of symbiont assemblages, evidence of a local symbiont extinction, and indications that local human disturbance may impede symbiont recovery following a major marine ...

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 ...

Finding of 132, 173‐cyclopheophorbide a enol as a degradation product of chlorophyll in shrunk zooxanthellae of the coral Montipora digitata

Journal of Phycology, 2015
We examined the morphology and pigment composition of zooxanthellae in corals subjected to normal temperature (27°C) and thermal stress (32°C). We observed several normal and abnormal morphological types of zooxanthellar cells.

Ancient Hybridisation Fuelled Diversification in Acropora Corals

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Introgression is the infiltration or flow of genes from one species to another through hybridisation followed by backcrossing. This may lead to incorrect phylogenetic reconstruction or divergence‐time estimation. Acropora is a dominant genus of reef‐building corals; however, whether this group has an introgression history before their ...

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 ...

Fitness of Cassiopea polyps Inoculated with Different Types of Symbionts

Ilmu Kelautan, 2022
The specificity of the relationship between cnidarian hosts and symbiotic dinoflagellates (zooxanthellae) differs among host species. Some cnidarian hosts can establish symbiotic relationship with various types of zooxanthellae, while others exhibit high

Increasing pCO2 correlates with low concentrations of intracellular dimethylsulfoniopropionate in the sea anemone Anemonia viridis. [PDF]

, 2014
Marine anthozoans maintain a mutualistic symbiosis with dinoflagellates that are prolific producers of the algal secondary metabolite dimethylsulfoniopropionate (DMSP), the precursor of the climate-cooling trace gas dimethyl sulfide (DMS).

Advances in coral reef restoration in the Mexican Pacific: active interventions and scaling approaches

Restoration Ecology, Volume 33, Issue 8, November 2025.
Abstract Introduction Coral reefs face escalating threats from the synergic effects of natural and anthropogenic stressors, challenging traditional conservation strategies and prompting the emergence of direct intervention approaches for coral reef restoration.
