Persistent Legacy Effects of Marine Heatwaves on Coral Symbioses. [PDF]

Glob Chang Biol
The algal symbionts hosted by Platygyra ryukyuensis corals on Kiritimati Island were distributed according to their exposure to local human disturbance before an extreme marine heatwave (1). The symbionts hosted by corals underwent a major shift as a result of this acute heatwave disturbance, with transient symbionts detected in corals at less turbid ...

Rapid Evolution in a Coral Population Following a Mass Mortality Event. [PDF]

Evol Appl
ABSTRACT Globally, corals face an increased frequency of mass mortality events (MMEs) as populations experience repeated marine heatwaves which disrupt their obligate algal symbiosis. Despite greater occurrences of MMEs, the relative roles of the environment, host, and symbiont genetic variation in survival, subsequent recovery, and carry‐over effects ...

The effect of the initial proportion of Durusdinium trenchii on photochemical efficiency and the rate of decline in symbiont to host ratio during heat stress

, 2020
With increasing rates of greenhouse gas emissions, tropical coral reefs are suffering from increasingly frequent and severe episodes of temperature-induced coral bleaching.

Endosymbiont Communities in Pachyseris speciosa Highlight Geographical and Methodological Variations

Frontiers in Marine Science, 2021
Reef-building corals live in symbiosis with the phototrophic dinoflagellate family Symbiodiniaceae, which comprises diverse genera such as Cladocopium and Durusdinium.

Marine Heatwaves Transform Coral Symbioses With Enduring Effects. [PDF]

Ecol Lett
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 ...

Diversity and distribution of Symbiodiniaceae detected on coral reefs of Lombok, Indonesia using environmental DNA metabarcoding [PDF]

PeerJ, 2022
Background Dinoflagellates of family Symbiodiniaceae are important to coral reef ecosystems because of their contribution to coral health and growth; however, only a few studies have investigated the function and distribution of Symbiodiniaceae in ...

Differential Symbiodiniaceae Association With Coral and Coral-Eroding Sponge in a Bleaching Impacted Marginal Coral Reef Environment

Frontiers in Marine Science, 2021
Marginal reefs are known for severe stress-inducible perturbations such as high sedimentation, eutrophication, ocean warming, and acidification from anthropogenic climate change.

Seasonal Physiological Strategies Reveal Contrasting Host-Symbiont Dynamics Among Dominant Indo-Pacific Reef-Building Corals. [PDF]

Ecol Evol
Seasonal changes in coral physiology reveal distinct acclimatization strategies among reef‐building corals. Symbiotic generalists exhibit large seasonal fluctuations driven primarily by symbiont dynamics, whereas symbiotic specialists maintain stable symbiont physiology through stronger host regulation.

Importance of depth and temperature variability as drivers of coral symbiont composition despite a mass bleaching event

Scientific Reports, 2023
Coral reefs are iconic examples of climate change impacts because climate-induced heat stress causes the breakdown of the coral-algal symbiosis leading to a spectacular loss of color, termed ‘coral bleaching’.

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 ...
