Long-term dynamics and theoretical considerations in coral holobiont adaptation [PDF]

Corals are predicted to adapt to environmental change in two ways: through the nuclear evolution of the host and/or through acquiring new, more suitable symbiotic partners. Given the rapid rate of climate change, considerable attention has focused on the

Host and Symbionts in Pocillopora damicornis Larvae Display Different Transcriptomic Responses to Ocean Acidification and Warming

Frontiers in Marine Science, 2018
As global ocean change progresses, reef-building corals and their early life history stages will rely on physiological plasticity to tolerate new environmental conditions.

Cryptic Interactions in a Marine Microcosm: Sponges Shape the Microbiome of a Resident Goby

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Microbial symbionts influence ecological and evolutionary processes in their multicellular hosts; yet they remain poorly characterised in marine systems. Sponges host exceptionally diverse microbiomes, potentially providing rich microbial reservoirs for their residents.

A Zeaxanthin-Producing Bacterium Isolated from the Algal Phycosphere Protects Coral Endosymbionts from Environmental Stress

mBio, 2020
Reef-building corals form a complex consortium with photosynthetic algae in the family Symbiodiniaceae and bacteria, collectively termed the coral holobiont.

On the Fate of Butyl Methoxydibenzoylmethane (Avobenzone) in Coral Tissue and Its Effect on Coral Metabolome

Metabolites, 2023
The intensive use of sunscreen products has raised concerns regarding their environmental toxicity and the adverse impacts of ultraviolet (UV) filters on ecologically important coral communities.

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

Changes in the Number of Symbionts and Symbiodinium Cell Pigmentation Modulate Differentially Coral Light Absorption and Photosynthetic Performance

Frontiers in Marine Science, 2017
In order to understand the contribution of pigmented coral tissues to the extraordinary optical properties of the coral-symbiont-skeleton unit, we analyzed the associations between structural and optical traits for four coral species, which broadly ...

Biogeographical Patterns of Coral‐Associated Symbiodiniaceae Across Thermal Regimes Including Trace Molecular Detection of Cladocopium thermophilum (C3‐Gulf) in the Seychelles

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Reef‐building corals rely on symbiotic dinoflagellates (Symbiodiniaceae) for survival; however, the distribution of thermotolerant symbionts across environmental gradients remains poorly understood. Using ITS2 metabarcoding across three bioregions spanning extreme to moderate thermal regimes (Bahrain, Seychelles, and Indonesia), we show that ...

The Algal Symbiont Modifies the Transcriptome of the Scleractinian Coral Euphyllia paradivisa during Heat Stress

Microorganisms, 2019
The profound mutualistic symbiosis between corals and their endosymbiotic counterparts, Symbiodiniaceae algae, has been threatened by the increase in seawater temperatures, leading to breakdown of the symbiotic relationship—coral bleaching.
