Marine organisms' persistence hinges on the capacity for acclimatization and adaptation to the myriad of interacting environmental stressors associated with global climate change. In this context, epigenetics-mechanisms that facilitate phenotypic variation through genotype-environment interactions-are of great interest ecologically and evolutionarily. Our comprehensive review of marine environmental epigenetics guides our recommendations of four key areas for future research: the dynamics of…

The high level of earthworm genome methylation for an invertebrate species, responsiveness of epigenome to environmental stimuli, availability of molecular resources, and the possibility to study epigenetic inheritance make earthworms adequate models in environmental epigenomics, but there are still many knowledge gaps that need to be filled in, before they can fully explore earthworms as models in this field.

Genome Survey of Chromatin-Modifying Enzymes in Threespine Stickleback: A Crucial Epigenetic Toolkit for Adaptation?

This work characterized the evolution of the gene toolkit involved in key molecular epigenetic pathways including DNA methylation, histone modifications, macroH2A histone, and miRNA biogenesis/turnover in threespine stickleback, a model species in evolution and ecology and revealed that teleost gene evolution is diversified and complex.

Reel-building corals are under threat from anthropogenic impacts and the partners of the coral holobiont and coral developmental process provide symbiotic, epigenetic and genetic mechanisms for acclimatization and adaptation to climate change.

Windows of opportunity: Ocean warming shapes temperature‐sensitive epigenetic reprogramming and gene expression across gametogenesis and embryogenesis in marine stickleback

This study identified key stages during gamete and embryo development with temperature‐sensitive reprogramming and epigenetic gene regulation, reflecting potential ‘windows of opportunity’ for adaptive epigenetic responses under future climate change.

Complementary genomic and epigenomic adaptation to environmental heterogeneity

Both shared and specific genes and biological pathways among genetic and epigenetic loci associated with environmental factors are found, consistent with complementary and independent contributions of genetic and DNA sequence‐based variation to environmental adaptation in this system.

Intergenerational epigenetic inheritance in reef-building corals

Examination of intergenerational DNA methylation profiles in a reef-building coral shows there to be genome-wide inheritance, with the potential for adaptive capacity to environmental stressors, which could extend to enhancing their capacity to adapt to climate change.

How is epigenetics predicted to contribute to climate change adaptation? What evidence do we need?

Epigenetic responses and other transgenerational effects will undoubtedly play a role in climate change adaptation, but further, well-designed, studies are required to test their importance relative to DNA-encoded changes.

Seasonal DNA Methylation Variation in the Flat Tree Oyster Isognomon Alatus from a Mangrove Ecosystem in North Biscayne Bay, Florida

The present study is the first long-term study combining spatial and temporal epigenetic analyses in a marine organism in its natural environment, laying the initial groundwork to assess the biomonitoring potential of environmental epigenetics analyses.

The epigenetic landscape of transgenerational acclimation to ocean warming

This study shows that the coral reef fish has 193 genes correlated to the transgenerationally acclimating phenotypic trait, aerobic scope, with functions in insulin response, energy homeostasis, mitochondrial activity, oxygen consumption and angiogenesis, suggesting an epigenetic basis of acclimation.

Ecological plant epigenetics: Evidence from model and non-model species, and the way forward.

To understand the true significance of epigenetics for plant ecology and evolution, it must combine both approaches transferring knowledge and methods from model-species research to genomes of evolutionarily divergent species, and examining responses to complex natural environments at a more mechanistic level.

Molecular and Biochemical Methods Useful for the Epigenetic Characterization of Chromatin-Associated Proteins in Bivalve Molluscs

The tools and protocols described here complement current epigenetic analyses (usually limited to DNA methylation) by incorporating the study of structural elements modulating chromatin dynamics, which are very limited in most non-traditional model organisms and even completely lacking in most environmentally and ecologically relevant organisms.

Morphological and epigenetic variation in mussels from contrasting environments

Although inconsistent, the topographically linked variability in epigenetic and the phenotypic differences in genetically close populations of mussels highlights the potential role of the local environment in driving mesoscale differences among populations.

Ocean acidification influences host DNA methylation and phenotypic plasticity in environmentally susceptible corals

The data suggest corals differ in their temporal dynamics and sensitivity for environmentally triggered real‐time epigenetic reprogramming, and the generation of potentially heritable plasticity via environmental induction of DNA methylation provides an avenue for assisted evolution applications in corals under rapid climate change.
