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.

Coral reefs are one of the most diversified ecosystems globally, providing food and shelter to a wide variety organisms. It serves as mutual relationship for various marine fauna. also offers multiple ecological services goods is an integral part income generation through tourism recreational activities. Despite their significant value, coral cladding substantial challenges from global climate change phenomenon led by anthropogenic Global warming subset broader phrase change. specifies observed rise in average air temperature near earth's surface seas due rapid increase greenhouse gases caused numerous bleaching, destruction reef structure, ocean acidification, increased diseases, etc., consequences faced Overall, can drastically alter ecosystem's biodiversity spectrum, function, productivity. Cooperative solid action required lessen effects on scale its repercussion corals.

The ecological factors of aquatic environments are changing because global climate change, which can directly or indirectly influence the expression different phenotypic traits in many organisms.The present study was conducted under laboratory conditions to unveil effects salinity and pH on some selected male guppy (Poecilia reticulata)a small freshwater live-bearing promiscuous fish species.The findings revealed that both had significant courtship behaviors (e.g.sigmoid displays gonopodial thrusts).The results also showed body size (e.g. standard length area) skin pigmentation (e.g.orange spot area).However, found manipulations these change parameters no effect other color numbers areas.These elicit further information about environmental condition dependent reproductive fishes, would help take necessary strategies for breeding, conservation management species a environment.
