Abstract The environment experienced by one generation has the potential to affect subsequent through non-genetic inheritance of parental effects. Since both mothers and fathers can influence their offspring, questions arise regarding how maternal, paternal offspring experiences integrate into resulting phenotype. We aimed disentangle maternal contributions transgenerational thermal acclimation in a reef fish, Acanthochromis polyacanthus , exposing two generations elevated temperature (+1.5°C) full factorial design analyzing F2 hepatic gene expression. Paternal effects showed common but also parent-specific components, with father having largest shaping transcriptomic profile. Fathers contributed response warming transfer epigenetically controlled stress-response mechanisms while influenced increased lipid metabolism regulation. However, key was matching parents. When parents were exposed same condition, structural RNA production transcriptional regulation, whereas environmental mismatch resulted maladaptive condition-transfer, revealed translation suppression endoplasmic reticulum stress. Interestingly, offspring’s own experience had smallest on transcription profiles. Taken together, our results show complex nature interplay between paternal, cue integration, reveal that ocean depends not only contributions, importantly congruent experiences.

Despite 22% of the world's coastal regions experiencing some degree light pollution, and biologically important artificial at night (ALAN) reaching large portions seafloor (greater than 75%) near developments, impacts ALAN on temperate tropical reefs are still relatively unknown. Because many reef species have evolved in response to low-light nocturnal environments, consistent daily, lunar, seasonal cycles, distinct spectra, these likely be profound. Recent studies found can decrease reproductive success fishes, alter predation rates invertebrates impact physiology biochemistry reef-building corals. In this paper, we integrate knowledge role natural with a synthesis current literature organisms explore potential changes system level communities exposed ALAN. Specifically, identify direct individual flow effects for communities, present scenarios where could significantly system-level dynamics, possibly even creating novel ecosystems. Lastly, highlight gaps our understanding overall systems. This article is part theme issue ‘Light pollution complex ecological systems’.

The parental environment can alter offspring phenotypes via the transfer of non-genetic information. Parental effects may be viewed as an extension (within-generation) phenotypic plasticity. Smaller size, poorer physical condition, and skewed sex ratios are common responses organisms to global warming, yet whether alleviate, exacerbate, or have no impact on these has not been widely tested. Further, relative influence mothers fathers ontogenetic timing exposure warming is poorly understood. Here, we tested how maternal, paternal, biparental a coral reef fish (

Population and species persistence in a rapidly warming world will be determined by an organism's ability to acclimate warmer conditions, especially across generations. There is potential for transgenerational acclimation but the importance of ontogenetic timing transmission environmentally induced parental effects remains mostly unknown.

Understanding the role of epigenetic inheritance in development adaptive and maladaptive traits aquatic species is challenging due to complexity mechanisms involved. Water chemistry, photoperiod, temperature, social hierarchy, food, pathogens, anthropological stressors constantly affect well-being via modulation footprints. Accumulating evidence suggests that epigenetically inherited effects can lead negative outcomes or promote phenotypes offspring experiencing similar environmental challenges. This chapter will discuss both positive organisms underlying mechanisms, taking some examples mammals as a reference.

We aimed disentangle contributions two critical stages (juvenile development adult reproduction) plasticity, exposing coral reef fish Acanthochromis polyacanthus simulated ocean with natural diel thermal fluctuations By using hepatic transcriptomics, we discovered that developmental environment offspring themselves had little effect on their acclimation at 2.5 months life. Instead, experience parents increased regulatory RNA production protein synthesis, which could improve offspring’s response warming. Conversely, reproduction water elicited stress mechanisms, suppression translation mitochondrial respiration. Mismatches between temperatures deeply affected gene expression profiles, detrimental were also evident when occurred both during parents’ reproduction. This study reveals previous generation’s temperature contributes substantially early life, however prolonged heat likely have adverse species’ persistence.

We aimed disentangle maternal contributions transgenerational thermal acclimation in a reef fish, Acanthochromis polyacanthus, exposing two generations elevated temperature (+1.5°C) fully factorial design analysing F2 hepatic gene expression. Paternal effects showed not only common but also parent-specific components, with father having largest shaping offspring's transcriptomic profile. Fathers contributed transcriptional response warming transfer epigenetically controlled stress-response mechanisms while influenced increased expression associated lipid metabolism regulation. However, key was matching parents. When parents were exposed same condition, genes related structural RNA production regulation, whereas environmental mismatch resulted maladaptive condition transfer, revealed translation suppression endoplasmic reticulum stress.
