Understanding how rising temperatures, ocean acidification, and hypoxia affect the performance of coastal fishes is essential to predicting species-specific responses climate change. Although a population’s habitat influences physiological performance, little work has explicitly examined multi-stressor species from habitats differing in natural variability. Here, clearnose skate (Rostaraja eglanteria) summer flounder (Paralichthys dentatus) mid-Atlantic estuaries, thorny (Amblyraja radiata) Gulf Maine, were acutely exposed current projected temperatures (20, 24, or 28 °C; 22 30 9, 13, 15 °C, respectively) acidification conditions (pH 7.8 7.4). We tested metabolic rates tolerance using intermittent-flow respirometry. All three exhibited increases standard rate under an 8 °C temperature increase (Q10 1.71, 1.07, 2.56, respectively), although this was most pronounced skate. At lowest test low pH treatment, all significant (44–105%; p < 0.05) decreases (60–84% critical oxygen pressure; 0.05). This study demonstrates interactive effects increasing changing carbonate chemistry are species-specific, implications which should be considered within context habitat.

Abstract The effects of increased levels carbon dioxide (CO 2 ) on the Earth's temperature have been known since end 19th century. It was long believed that oceans' buffering capacity would counteract any dissolved CO in marine environments, but during recent decades, many studies reported detrimental ocean acidification aquatic organisms. most prominent can be found within field behavioural ecology, e.g ., complete reversal predator avoidance behaviour ‐exposed coral reef fish. Some very influential, receiving hundreds citations over years. results also conveyed to policymakers and publicized media outlets for general public. Those extreme fish have, however, spurred controversy, given more than a century research suggests there are few or no negative elevated physiology. This is due sophisticated acid–base regulatory mechanisms should enable their resilience near‐future increases . In addition, an “decline effect” has recently shown literature regarding behaviour, independent groups unable replicate some profound effects. Here, author presents brief historical overview fishes. recap warranted because earlier work, prior ( c. 10 year) explosion interest, often overlooked today's studies, despite its value field.
