Resolving widespread and endemic dinoflagellates (Symbiodiniaceae) mutualistic with Indo-Pacific octocorals reveals differences in specificity based on host phylogeny. [PDF]

J Phycol
Abstract Endosymbionts in the dinoflagellate family Symbiodiniaceae can form mutualisms with a diverse array of host invertebrates, constituting a widespread and ecologically important family. While those associated with reef‐building corals (order Scleractinia) have received considerable research attention, the diversity and ecology of zooxanthellae ...

Heat Stress Drives Rapid Viral and Antiviral Innate Immunity Activation in Hexacorallia. [PDF]

Mol Ecol
ABSTRACT The class Hexacorallia, encompassing stony corals and sea anemones, plays a critical role in marine ecosystems. Coral bleaching, the disruption of the symbiosis between stony corals and zooxanthellate algae, is driven by seawater warming and further exacerbated by pathogenic microbes.

Diversity and Prevalence of Coral Diseases in the Nearshore Regions of the Northern South China Sea. [PDF]

Ecol Evol
This study presents the first systematic survey of coral disease diversity and prevalence in the nearshore regions of the northern South China Sea. Six common diseases and eight stress‐related phenomena were documented across seven sites, revealing distinct regional patterns and host‐specific susceptibilities.

Skeleton Precedes Polyp: Visualization of Structural Changes During Coral Growth in <i>Montipora capricornis</i>. [PDF]

Ecol Evol
Using high‐resolution micro‐computed tomography, this study demonstrates that in Montipora capricornis, skeleton–canal network formation precedes polyp budding at colony margins, with a “transit area” (volumes ~1 mm3, skeleton‐to‐void ratio 20%–35%) in tubular canals serving as a pathway for polyp migration to new calices.

Indeks Mitotik Simbion Alga Zooxanthellae pada Anemon Laut Stichodactyla gigantean Hasil Reproduksi Aseksual (Mitotic Index of Algal Symbion Zooxanthellae on Giant Carpet Anemone (Stichodactyla gigantea) Resulted from Asexual Reproduction)

Ilmu Kelautan, 2014
Zooxanthella adalah alga simbiotik yang hidup berasosiasi secara mutualisme pada jaringan endodermis anemon laut. Dinamika alga zooxanthellae telah banyak diketahui pada anemon hasil reproduksi seksual namun sebaliknya pada anemon hasil reproduksi ...

Breakdown of the coral-algae symbiosis: towards formalising a linkage between warm-water bleaching thresholds and the growth rate of the intracellular zooxanthellae [PDF]

Biogeosciences, 2013
Impairment of the photosynthetic machinery of the algal endosymbiont ("zooxanthellae") is the proximal driver of the thermal breakdown of the coral-algae symbiosis ("coral bleaching"). Yet, the initial site of damage, and early dynamics of the impairment

Symbiont diversity is not involved in depth acclimation in the Mediterranean sea whip Eunicella singularis [PDF]

, 2011
In symbiotic cnidarians, acclimation to depth and lower irradiance can involve physiological changes in the photosynthetic dinoflagellate endosymbiont, such as increased chlorophyll content, or qualitative modifications in the symbiont population in ...

Growth and Extracellular Carbonic Anhydrase Activity of Zooxanthellae Symbiodinium sp. in Response of Zinc Enrichment

Hayati Journal of Biosciences, 2011
Coral reef communities contain a wide variety of mutualistic associations none more important than the relationship between corals and their symbiotic dinoflagellates of the genus Symbiodinium sp., commonly referred to as zooxanthellae.

Red light represses the photophysiology of the scleractinian coral Stylophora pistillata. [PDF]

PLoS ONE, 2014
Light spectrum plays a key role in the biology of symbiotic corals, with blue light resulting in higher coral growth, zooxanthellae density, chlorophyll a content and photosynthesis rates as compared to red light.

Fast growth may impair regeneration capacity in the branching coral Acropora muricata. [PDF]

PLoS ONE, 2013
Regeneration of artificially induced lesions was monitored in nubbins of the branching coral Acropora muricata at two reef-flat sites representing contrasting environments at Réunion Island (21°07'S, 55°32'E). Growth of these injured nubbins was examined
