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.

Nitrogen source type modulates heat stress response in coral symbiont (Cladocopium goreaui)

Applied and Environmental Microbiology
Ocean warming due to climate change endangers coral reefs, and regional nitrogen overloading exacerbates the vulnerability of reef-building corals as the dual stress disrupts coral–Symbiodiniaceae mutualism.

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 ...

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-evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts. [PDF]

New Phytol
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Advancing Symbiodiniaceae Functional Ecology Through a Trait-Based Framework. [PDF]

Ecol Evol
Symbiodiniaceae dinoflagellates are central to coral reef functioning, supporting primary production, nutrient cycling, calcification, and influencing coral thermal tolerance through intracellular symbiosis. Despite their ecological importance, these symbionts have not yet been incorporated into a formal functional ecology framework due to challenges ...

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 ...

Nitrogen availability improves the physiological resilience of coral endosymbiont Cladocopium goreaui to high temperature [PDF]

Journal of Phycology, 2021
The physiological response of symbiotic Symbiodiniaceae to high temperature is believed to result in coral bleaching. However, the potential effect of nitrogen availability on heat acclimatization of symbiotic Symbiodiniaceae is still unclear. In this study, physiological responses of Symbiodiniaceae Cladocopium goreaui to temperature and nitrogen ...

Algal Symbionts Indicate Heatwave Vulnerability in Corals From Hotspots but Not From Thermal Refugia. [PDF]

Mol Ecol
ABSTRACT Reef‐building corals face continued declines due to climate change‐amplified marine heatwaves. In addition to affecting coral heat tolerance, corals' algal endosymbionts (family Symbiodiniaceae) can reflect their prior heatwave exposure, although understanding is often limited to heatwave‐induced shifts between symbiont genera.
