The Influence of Symbiont Identity on the Proteomic and Metabolomic Responses of the Model Cnidarian Aiptasia to Thermal Stress. [PDF]
We examined the effects of symbiont identity and heat stress on the host metabolome and proteome in the cnidarian-dinoflagellate symbiosis. Exaiptasia diaphana ('Aiptasia') was inoculated with its homologous (i.e., native) symbiont Breviolum minutum or a

Transcriptome Analysis of Durusdinium Associated with the Transition from Free-Living to Symbiotic [PDF]
To detect the change during coral–dinoflagellate endosymbiosis establishment, we compared transcriptome data derived from free-living and symbiotic Durusdinium, a coral symbiont genus. We detected differentially expressed genes (DEGs) using two statistical methods (edgeR using raw read data and the Student’s t-test using bootstrap resampling read data)

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

Using Transcript Levels of Nitrate Transporter 2 as Molecular Indicators to Estimate the Potentials of Nitrate Transport in Symbiodinium, Cladocopium, and Durusdinium of the Fluted Giant Clam, Tridacna squamosa [PDF]
Giant clams are important ecosystem engineers of coral reefs because they harbor large quantities of phototrophic Symbiodiniaceae dinoflagellates of mainly genera Symbiodinium, Cladocopium, and Durusdinium. The coccoid dinoflagellates donate photosynthate and amino acids to the clam host, which in return needs to supply inorganic carbon and nitrogen to

New Findings on the Survival of <i>Durusdinium glynnii</i> Under Different Acclimation Methods to Low Salinities. [PDF]
This study investigated the effects of salinity on the growth and cell morphotype of the coral-associated dinoflagellate Durusdinium glynnii under two acclimation strategies: abrupt saline shock (S5) and gradual reduction (S2). Results revealed optimal growth rates (µ = 0.22–0.35 day−1) at salinities of 20–30 g L−1, while extreme conditions (10 and 40 ...

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

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

Coral Skeletal Cores as Windows Into Past Symbiodiniaceae Community Dynamics. [PDF]
Stony corals rely on their association with symbiotic algae for their growth and health. However, corals can lose these symbionts in response to heat stress and bleach, but they can also recover from bleaching and associate with new, more tolerant symbionts.

Population Genomics for Coral Reef Restoration-A Case Study of Staghorn Corals in Micronesia. [PDF]
ABSTRACT Staghorn Acropora corals are ecological keystone species in shallow lagoons and back reef habitats throughout the tropics. Their widespread decline coupled with their amenability for asexual propagation propelled them to the forefront of global coral restoration efforts—albeit frequently without much scientific input.
