“…RNA quality and quantity were assessed using a Bioanalyzer 2100 and RNA 6000 Nano LabChip Kit (Agilent), and high-quality RNA samples (RIN > 7.0) were used to construct the sequencing library. 20 Briefly, mRNA was purified from total RNA using Dynabeads Oligo (dT) (Thermo Fisher Scientific), followed by fragmentation using divalent cations at 94 °C for 5 min. The cleaved RNA fragments were reverse transcribed into cDNA using SuperScript II Reverse Transcriptase (Invitrogen, USA).…”

Studies have demonstrated adverse effects of global warming on aquatic ecosystems from the abiotic to the biotic level. In the present work, a meta-analysis study was conducted to elucidate the effects of global warming on spermatozoa functions, which are key determinants of male fertility. We recruited 245 data records from a pool of empirical studies, which includes 20 studies spanning 20 cold- and warm-water fish species, to identify the effects of increased water temperature (IWT) on determinants of sperm fertility in fishes. Data were systematically re-processed and re-analyzed to determine the overall effects of IWT on sperm kinetics such as motility (MOT), duration of motility (DSM), curvilinear velocity (VCL), rectilinear velocity (VSL) and average path velocity (VAP), as well as on enzymatic activities for energy supply (EAES) and antioxidant enzyme activity (ANEA). The standardized mean difference was calculated for each study, with positive values indicating higher performance under IWT. Results showed that (a) the overall effect size for MOT was more negative in cold-water fishes (-1.22) than in warm-water fishes (-0.98). (b) Each 1 oC increase in the activation medium reduced MOT by 1.30% (cold-water fishes) and 3.47% (warm-water fishes). (c) The IWT negatively affected DSM, decreasing it by 10 s (cold-water species) and 5.64 s (warm-water species) per degree of IWT. (d) Spermatozoa velocity (VCL and VSL) was increased by IWT in warm-water species. In conclusion, this study shows that IWT negatively affects sperm motility kinetics, suggesting an impact of global warming on fish reproduction.

“…Therefore, O . melastigma has been widely used in marine ecological toxicology studies [ 28 , [33] , [34] , [35] ]. For O. melastigma , the embryo develops a regular heartbeat at 5 days postfertilization (dpf), shows the highest heart rate at 8 dpf, and achieves a constant heart rate at 11 dpf [ 36 ].…”
