“…Hence, we hypothesized that the transcriptional levels of metabolism pathways are affected by temperature increases in T. bleekeri, resulting in changes in metabolites. Liver tissue is a lynchpin in metabolic reprogramming in response to temperature changes (Barat et al, 2016;Lyu et al, 2018;Paul et al, 2021). In this study, we characterized the lipid metabolite changes in the liver of T. bleekeri at high temperatures using a hybrid quadrupole time-offlight mass spectrometry (UHPLC-QTOF-MS) and gas chromatography-mass spectrometry (GC-MS) analysis.…”

The effect of thermal changes on the physiology and behavior of fish is a major research focus in the face of ongoing global warming. There is little information about the effects of temperature increase on fish in the wild. However, the consequences of temperature increase on fish in controlled laboratory conditions can provide insights into what can be expected in the wild. Triplophysa bleekeri, a high-plateau fish, exhibits high sensitivity to high temperatures, suggesting it to be a good model to investigate the impact of temperature increase on fish. In this study, we analyzed the effect of gradual temperature increase on transcriptional and metabolic levels of T. bleekeri subjected to a gradual temperature change of 0.5°C/day until temperatures of 10°C, 13°C, 16°C, and 19°C were reached. Transcriptomics results of the liver, gut, spleen, and trunk kidney showed that metabolic pathways are widely involved in the response to increased temperatures in T. bleekeri. Lipidomics results further indicated that the lipid composition was altered by increased temperatures, and three lipids (PC 14:0e/22:1, PC 18:0e/22:5, and TAG 14:3-21:2-21:2) were identified as potential biomarkers of heat stress in T. bleekeri. Moreover, a decline in unsaturated fatty acid levels was observed in T. bleekeri under high temperatures. These results suggest that high temperatures modify the metabolomic pathways. Overall, our results help improve the understanding of physiological responses in fish to increased temperatures, and provide valuable information predicting the consequences of global warming on fish.

“…Of great usefulness in the energetic realm is also the measurement of the ratio of metabolic key aerobic metabolism enzyme lactate dehydrogenase (LDH; EC 1.1.1.27) and anaerobic metabolism isocitrate dehydrogenase (IDH; EC 1.1.1.41 and EC 1.1.1.42). Under stressful condition, organisms to mobilize more and faster energy for metabolic purposes will rely to a greater extent on the anaerobic path and thus this LDH/IDH will tend to increase which may then be used as a proxy for the metabolic use of energy [ 42 ]. Increased respiration will lead to cellular oxidative stress brought by accumulating ROS, adding significance to measuring a bundle of these stress-related biomarkers to enlighten stress effects.…”

“…Besides acidification, temperature changes are a key issue for climate change, which has also been studied addressing biomarkers. In research on the rock pool fish Gobius paganellus , Paul et al [ 42 ] found that the increase of temperature led to decreased growth, increased LDH/IDH ratio (due to increased anaerobic metabolism), decreased ETS, and increased DNA damage. They also found that predation risk impacted this organism’s cellular metabolism, but the severity of effects of thermal stress clearly outweighed metabolism-related responses to predation stress increasing the risk of being preyed upon and inducing an extra energy trade-off for the basal metabolism, which may have ecologically relevant consequences.…”

Endpoints assessed at the population or community level are most often the result of the sum of effects on individuals, arising from the effects at the cellular and molecular levels. Within this framework, these lower biological level endpoints are more responsive at an early stage of exposure, making them potential toolboxes to be used as early-warning markers to address stress. Given this, by linking responses and understanding organisms’ metabolism and physiology, the possibilities for the use of biomarkers in stress biology are vast. Here, biomarker comprehensive examples are given to enlighten the need to link levels of biological organization, and their usefulness for a myriad of fields and applications is presented and discussed.

“…The synergistic effect of predator and thermal stressors examined by Jermacz, Kletkiewicz, Krzyzynska, et al (2020) indicated increased cellular damage under predation risk in various thermal regimes and reduced activity of antioxidant system in amphipods. Paul et al (2021) showed inconsistent results on fish Gobius paganellus, whose antioxidant response was not induced due to exposition to predator pressure and elevated temperature; however, chronic exposure to predation risk revealed significant DNA damage. Non-consumptive effect of predator-prey relationship alone can also induce oxidative damage (Janssens & Stoks, 2013;.…”

Changes in oxidative status represent organismal response to stressful external stimuli. While there is substantial knowledge on the influence of abiotic factors on the antioxidant system of different organisms, the impact of biotic factors remains largely unexplored. The aim of the present study was to evaluate the effect of acute competitive interactions on oxidative stress. Territory‐resident and intruder round goby Neogobius melanostomus individuals were experimentally subjected to competition for limited shelter resource in three treatments (lasting 1, 6 and 12 h), and oxidative stress parameters (total antioxidant capacity, catalase activity, reduced glutathione, lipid peroxidation), as well as behaviour (time spent in the shelter, guarding the shelter and aggression) were measured. All tested biochemical parameters reached higher values in the liver than in the muscle tissue. Fish behaviour and antioxidant defence did not show any potential relationships reflecting changes in antioxidant status and aggression. Particularly, there was no difference between resident and intruder fish in oxidative stress parameters. We compared our results to the outcome of our previous studies (similar experimental protocol and species) but with acute heat shock as a stressor instead of competition. The higher temperature was found to be a stronger stressor than the competition, most pronounced in total antioxidant capacity and oxidative damage.
