ABSTRACT Studies have demonstrated adverse effects of global warming on aquatic ecosystems. However, the increased water temperature (IWT) fish reproduction are still doubtful in species spawning at low or high temperatures. In this meta‐analysis, we elucidated spermatozoa functions, key determinants male fertility. We recruited 245 data records from 20 studies spanning cold‐ and warm‐water fishes to identify IWT sperm quality. Data were re‐processed re‐analyzed determine overall kinetics such as percentage motile (MOT), duration motility (DSM), curvilinear velocity (VCL), straight line (VSL), average path (VAP), well enzymatic activities for energy supply (EAES) antioxidant enzyme activity (ANEA). The standardized mean difference was calculated each study, with positive values indicating higher performance under IWT. Results showed that (a) effect size MOT larger negative cold‐water (−1.22) than (−0.95). (b) Each 1°C increase activation medium reduced by 1.30% (cold‐water fishes) 3.47% (warm‐water fishes).

Hepatic Transcriptomic Responsiveness of Polar Cod, Boreogadus saida, to Ocean Acidification and Warming

Fishes, Год журнала: 2024, Номер 9(7), С. 271 - 271

Опубликована: Июль 10, 2024

Background: This study was part of a larger comprehensive project (BIOACID) addressing the physiological resilience Polar cod, Boreogadus saida, to ocean acidification and global warming aimed unravel underlying molecular mechanisms observed responses. Methods: Fish were acclimated long-term three CO2 concentrations comprising control conditions (390 ppm) two projected climate scenarios (780 ppm 1170 ppm). Each treatment combined with four temperatures: 0, 3, 6, 8 °C. Here, we focused on hepatic transcriptomic profiles from these previously physiologically characterized fish. Results: Generally, did not detect signs classical stress response. Consistent functional observations, induced much stronger responses compared elevated PCO2, but an interaction between both factors existed some extent. Gene ontology analysis revealed strong response in lipid, amino acid, protein metabolism. With increasing temperature, shift away lipid metabolism, while carbohydrate metabolic pathways remained stable. Conclusions: Although found cod be quite resilient acidification, temperature will remain critical parameter for this valuable Arctic keystone species, question remains as whether acclimation strategies can implemented its natural habitat, especially when food supply is limited.

Differential reproductive plasticity under thermal variability in a freshwater fish ( Danio rerio )

Proceedings of the Royal Society B Biological Sciences, Год журнала: 2022, Номер 289(1982)

Опубликована: Сен. 7, 2022

Human-driven increases in global mean temperatures are associated with concomitant thermal variability. Yet, few studies have explored the impacts of variability on fitness-related traits, limiting our ability to predict how organisms will respond dynamic changes. Among myriad organismal responses variability, one most proximate fitness—and, thus, a population's persist—is reproduction. Here, we examine model freshwater fish ( Danio rerio ) responds diel fluctuations that span species's viable developmental range temperatures. We specifically investigate reproductive performance metrics including spawning success, fecundity, egg provisioning and sperm concentration. Notably, apply treatments during two ontogenetic timepoints disentangle relative effects plasticity reversible acclimation. found evidence direct, negative later stages metrics. also complex interactive early late-life exposure beneficial acclimation success modification relationship between fecundity provisioning. Our findings illuminate plastic life-history modifications may undergo as their environments become increasingly variable.

Abstract Population and species persistence in a rapidly warming world will be determined by an organisms’ 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. 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.

Matching maternal and paternal experiences underpin molecular thermal acclimation

Molecular Ecology, Год журнала: 2024, Номер unknown

Опубликована: Март 23, 2024

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) 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. Interestingly, own experience had smallest on transcription profiles. Taken together, our results show complex nature interplay among paternal, cue integration, reveal that ocean might depend importantly congruent experiences.
