Seasonal Variation in In Hospite but Not Free-Living, Symbiodiniaceae Communities Around Hainan Island, China

Microorganisms
Coral 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

Stony coral tissue loss disease induces transcriptional signatures of in situ degradation of dysfunctional Symbiodiniaceae

Nature Communications, 2023
Stony coral tissue loss disease (SCTLD), one of the most pervasive and virulent coral diseases on record, affects over 22 species of reef-building coral and is decimating reefs throughout the Caribbean. To understand how different coral species and their

Concentrations, sources, and biological consumption of acrylate and DMSP in the tropical Pacific and coral reef ecosystem in Mo’orea, French Polynesia

Frontiers in Marine Science, 2022
Shallow-water coral reefs hold large quantities of acrylate and its precursor dimethylsulfoniopropionate (DMSP), but production and removal processes for these compounds are poorly characterized.

Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, Volume 251, Issue 4, Page 1755-1773, August 2026.
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 (

Weak Structure and Environment‐Associated Loci Across a Eutrophication Gradient in a Resilient Coral Species

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Marine species often have large effective population sizes and high connectivity that reduce drift and preserve diversity, but how these features shape adaptation to anthropogenic change remains unclear; Oulastrea crispata, a stress‐tolerant Indo‐Pacific coral, is an ideal test case along a strong eutrophication gradient. Using RADseq on 90 individuals

Light intensity changes and UVB radiation affect peridinin content and antioxidant activity in the Cassiopea andromeda holobiont

Frontiers in Marine Science, 2023
IntroductionThe up-side down jellyfish Cassiopea andromeda represents a yet untapped marine species that could be targeted as a new source for functional ingredients, such as natural pigments and antioxidants. Since C.

Phylogenetic analysis of cell-cycle regulatory proteins within the Symbiodiniaceae

Scientific Reports, 2020
In oligotrophic waters, cnidarian hosts rely on symbiosis with their photosynthetic dinoflagellate partners (family Symbiodiniaceae) to obtain the nutrients they need to grow, reproduce and survive.

Seasonal Physiological Strategies Reveal Contrasting Host–Symbiont Dynamics Among Dominant Indo‐Pacific Reef‐Building Corals

Ecology and Evolution, Volume 16, Issue 7, July 2026.
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.

A Lectin AtTL-2 Obtained from Acropora aff. tenuis Induced Stimualation of Phagocytosis of Symbiodiniaceae

Microorganisms
The coral Acropora aff. tenuis selectively acquired various zooxanthella (Symbiodiniaceae) strains, and one of the selective factors was lectins. The A. aff.

Bleaching Susceptibility and Resistance of Octocorals and Anemones at the World’s Southern-Most Coral Reef

Frontiers in Physiology, 2022
Coral reefs are amongst the most biodiverse ecosystems on earth, and while stony corals create the foundational complexity of these ecosystems, octocorals and anemones contribute significantly to their biodiversity and function.
