Long-Term Heat Selection of the Coral Endosymbiont Cladocopium C1acro (Symbiodiniaceae) Stabilizes Associated Bacterial Communities

International Journal of Molecular Sciences, 2022
Heat-tolerant strains of the coral endosymbiont, Cladocopium C1acro (Symbiodiniaceae), have previously been developed via experimental evolution. Here, we examine physiological responses and bacterial community composition (using 16S rRNA gene metabarcoding) in cultures of 10 heat-evolved (SS) and 9 wild-type (WT) strains, which had been exposed for 6 ...

Breviolum and Cladocopium Are Dominant Among Symbiodiniaceae of the Coral Holobiont Madracis decactis

Microbial Ecology, 2021
The scleractinian reef building coral Madracis decactis is a cosmopolitan species. Understanding host-symbiont associations is critical for assessing coral's habitat requirements and its response to environmental changes. In this study, we performed a fine grained phylogenetic analyses of Symbiodiniaceae associated with Madracis in two locations in the

Photosynthetic capacity of the endosymbiotic dinoflagellate Cladocopium sp. is preserved during digestion of its jellyfish host Mastigias papua by the anemone Entacmaea medusivora [PDF]

FEMS Microbiology Ecology, 2019
ABSTRACT The sea anemone Entacmaea medusivora (Actiniaria, Anthozoa) commonly feeds on the golden jellyfish Mastigias papua (Rhizostomeae, Scyphozoa) which harbours an endosymbiotic dinoflagellate of the genus Cladocopium (Symbiodiniaceae).

Interactive effects of acidification and copper exposure on the reproduction and metabolism of coral endosymbiont Cladocopium goreaui

Marine Pollution Bulletin, 2022
Ocean acidification resulting from increased CO2 and pollution from land-sourced toxicants such as copper have been linked to coral cover declines in coastal reef ecosystems. The impacts of ocean acidification and copper pollution on corals have been intensively investigated, whereas research on their effects on coral endosymbiont Symbiodiniaceae is ...

Physiological diversity among sympatric, conspecific endosymbionts of coral (Cladocopium C1acro) from the Great Barrier Reef

Coral Reefs, 2021
Most of the scleractinian corals living in the photic zone form an obligate symbiosis with dinoflagellates in the family Symbiodiniaceae that promotes reef accretion and niche diversification. However, sea surface temperature surpassing the normal summer average disrupts the symbioses, resulting in coral bleaching and mortality.

Shuffling between Cladocopium and Durusdinium extensively modifies the physiology of each symbiont without stressing the coral host

Molecular Ecology, 2021
Abstract As sea surface temperatures increase, many coral species that used to harbour symbionts of the genus Cladocopium have become colonized with the thermally tolerant genus, Durusdinium .

Ammonia transporter 2 as a molecular marker to elucidate the potentials of ammonia transport in phylotypes of Symbiodinium, Cladocopium and Durusdinium in the fluted giant clam, Tridacna squamosa

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2022
Giant clams harbor coccoid Symbiodiniaceae dinoflagellates that are phototrophic. These dinoflagellates generally include multiple phylotypes (species) of Symbiodinium, Cladocopium, and Durusdinium in disparate proportions depending on the environmental conditions. The coccoid symbionts can share photosynthate with the clam host, which in return supply

Physiological and molecular responses to urea environment in Cladocopium goreaui (Symbiodiniaceae)

Environmental Research
Nitrogen is an essential nutrient for photosynthetic productivity, and its enrichment in coral reef ecosystems due to anthropogenic activities has raised concerns about ecological impacts. Urea is a readily available nitrogen source that can influence nitrogen dynamics in coral reef ecosystems, but the underlying mechanisms of its assimilation and ...

Using form II ribulose-1,5-bisphosphate carboxylase/oxygenase to estimate the phototrophic potentials of Symbiodinium, Cladocopium and Durusdinium in various organs of the fluted giant clam, Tridacna squamosa, and to evaluate their responses to light upon isolation from the host

Coral Reefs, 2021
Mutualistic associations with symbiotic dinoflagellates (zooxanthellae) enable invertebrate hosts to thrive in tropical waters that are shallow and oligotrophic. Giant clams can harbor multiple species of symbiotic dinoflagellates (Family: Symbiodiniaceae) from mainly three genera, Symbiodinium, Cladocopium and Durusdinium, but whether they have ...

Polystyrene Microplastics Exhibit Toxic Effects on the Widespread Coral Symbiont Cladocopium Goreaui

Environmental Research
Within the coral reef habitat, members of the Symbiodiniaceae family stand as pivotal symbionts for reef-building corals. However, the physiological response of Symbiodiniaceae on microplastics are still poorly understood. Research conducted in this investigation assessed the harmful impact of polystyrene microparticles (PS-MPs) on Cladocopium goreaui,
