Diverse Internal Symbiont Community in the Endosymbiotic Foraminifera Pararotalia calcariformata: Implications for Symbiont Shuffling Under Thermal Stress [PDF]
Frontiers in Microbiology, 2018 Many shallow-water tropical and subtropical foraminifera engage in photosymbiosis with eukaryotic microalgae. Some of these foraminifera appear to harbor a diverse consortium of endosymbiotic algae within a single host.

Symbiont shuffling dynamics associated with photodamage during temperature stress in coral symbiosis
Ecological Indicators, 2022 Reef-building corals usually form a symbiotic relationship with various photosynthetic dinoflagellates, which may determine the physiology and stress tolerance of their hosts.

Investigating the causes and consequences of symbiont shuffling in a multi-partner reef coral symbiosis under environmental change [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2015 Dynamic symbioses may critically mediate impacts of climate change on diverse organisms, with repercussions for ecosystem persistence in some cases. On coral reefs, increases in heat-tolerant symbionts after thermal bleaching can reduce coral susceptibility to future stress.

Lineage-specific symbionts mediate differential coral responses to thermal stress [PDF]
Microbiome, 2023 Background Ocean warming is a leading cause of increasing episodes of coral bleaching, the dissociation between coral hosts and their dinoflagellate algal symbionts in the family Symbiodiniaceae.

Seasonal Variation in In Hospite but Not Free-Living, Symbiodiniaceae Communities Around Hainan Island, China [PDF]
MicroorganismsCoral reefs are increasingly threatened by global climate change, and mass bleaching and mortality events caused by elevated seawater temperature have led to coral loss worldwide. Hainan Island hosts extensive coral reef ecosystems in China, yet seasonal

Symbiont Community Changes Confer Fitness Benefits for Larvae in a Vertically Transmitting Coral [PDF]
Ecology and EvolutionCoral reefs worldwide are threatened by increasing ocean temperatures because of the sensitivity of the coral‐algal symbiosis to thermal stress. Reef‐building corals form symbiotic relationships with dinoflagellates (family Symbiodiniaceae), including ...

Symbiont shuffling across environmental gradients aligns with changes in carbon uptake and translocation in the reef-building coral Pocillopora acuta [PDF]
Coral Reefs, 2021 Symbiosis between reef-building corals and unicellular algae (Symbiodiniaceae) fuels the growth and productivity of corals reefs. Capacity for Symbiodiniaceae to fix inorganic carbon (Ci) and translocate carbon compounds to the host is central to coral health, but how these processes change for corals thriving in environmental extremes remains largely ...

Baseline shifts in coral skeletal oxygen isotopic composition: a signature of symbiont shuffling? [PDF]
Coral Reefs, 2013 Decades-long records of the stable isotopic composition of coral skeletal cores were analyzed from four sites on the Mesoamerican Reef. Two of the sites exhibited baseline shifts in oxygen isotopic composition after known coral bleaching events. Changes in pH at the calcification site caused by a change in the associated symbiont community are invoked ...

Real-time PCR reveals a high incidence of Symbiodinium clade D at low levels in four scleractinian corals across the Great Barrier Reef: implications for symbiont shuffling [PDF]
Coral Reefs, 2007 Reef corals form associations with an array of genetically and physiologically distinct endosymbionts from the genus Symbiodinium. Some corals harbor different clades of symbionts simultaneously, and over time the relative abundances of these clades may change through a process called symbiont shuffling.

Specificity trumps flexibility—location-based stable associations between Symbiodiniaceae genera and Platygyra verweyi (Scleractinia; Merulinidae) [PDF]
PeerJ, 2020 This study monitored symbiont communities bi-monthly in native coral cores used in a reciprocal transplantation of the coral Platygyra verweyi over two years (2014–2016) and samples of mother colonies from three locations with variable thermal regimes ...
