Pivotal to projecting the fate of coral reefs is the capacity of reef-building corals to acclimatize and adapt to climate change and the mechanisms that could enable adaptive plasticity in the coral holobiont, including the potential role of epigenetics and coral-associated microbes.Abstract:
Pivotal to projecting the fate of coral reefs is the capacity of reef-building corals to acclimatize and adapt to climate change. Transgenerational plasticity may enable some marine organisms to acclimatize over several generations and it has been hypothesized that epigenetic processes and microbial associations might facilitate adaptive responses. However, current evidence is equivocal and understanding of the underlying processes is limited. Here, we discuss prospects for observing transgenerational plasticity in corals and the mechanisms that could enable adaptive plasticity in the coral holobiont, including the potential role of epigenetics and coral-associated microbes. Well-designed and strictly controlled experiments are needed to distinguish transgenerational plasticity from other forms of plasticity, and to elucidate the underlying mechanisms and their relative importance compared with genetic adaptation.read more

TL;DR: This Consensus Statement documents the central role and global importance of microorganisms in climate change biology and puts humanity on notice that the impact of climate change will depend heavily on responses of micro organisms, which are essential for achieving an environmentally sustainable future.

Beyond buying time: The role of plasticity in phenotypic adaptation to rapid environmental change
TL;DR: The need for cross-disciplinary collaborations is advocated to settle the question of whether plasticity will promote or retard species' rates of adaptation to ever-more stressful environmental conditions.

Transgenerational plasticity and climate change experiments: Where do we go from here?
TL;DR: This review considers how the detection of TGP in climate change experiments is affected by the predictability of environmental variation, as well as the timing and magnitude of environmental change cues applied.

TL;DR: A meta-analysis focussing on birds suggests that global warming has not systematically affected morphological traits, but has advanced phenological traits and indicates that the evolutionary load imposed by incomplete adaptive responses to ongoing climate change may already be threatening the persistence of species.

TL;DR: In this paper, the authors show the emergence of ecological memory during unprecedented back-to-back mass bleaching of corals along the 2,300 km length of the Great Barrier Reef in 2016 and again in 2017, whereby the impacts of the second severe heatwave, and its geographic footprint, were contingent on the first.

TL;DR: It is proposed that this epigenetic marking system represents a fundamental regulatory mechanism that has an impact on most, if not all, chromatin-templated processes, with far-reaching consequences for cell fate decisions and both normal and pathological development.

TL;DR: The conventional view that DNA methylation functions predominantly to irreversibly silence transcription is being challenged and not only is promoter methylation often highly dynamic during development, but many organisms also seem to targetDNA methylation specifically to the bodies of active genes.

TL;DR: Recent technological and intellectual advances that have changed thinking about five questions about how have bacteria facilitated the origin and evolution of animals; how do animals and bacteria affect each other’s genomes; how does normal animal development depend on bacterial partners; and how is homeostasis maintained between animals and their symbionts are highlighted.

TL;DR: The distinctive geographic footprints of recurrent bleaching on the Great Barrier Reef in 1998, 2002 and 2016 were determined by the spatial pattern of sea temperatures in each year, suggesting that local protection of reefs affords little or no resistance to extreme heat.
