Climate Change Affects Marine Fishes Through the Oxygen Limitation of Thermal Tolerance

  title={Climate Change Affects Marine Fishes Through the Oxygen Limitation of Thermal Tolerance},

A cause-and-effect understanding of climate influences on ecosystems requires evaluation of thermal limits of member species and of their ability to cope with changing temperatures. Laboratory data available for marine fish and invertebrates from various climatic regions led to the hypothesis that, as a unifying principle, a mismatch between the demand for oxygen and the capacity of oxygen supply to tissues is the first mechanism to restrict whole-animal tolerance to thermal extremes. We show… 
Cod and climate in a latitudinal cline: physiological analyses of climate effects in marine fishes
Characteristics of temperature-dependent metabolic adaptation, as well as their impli- cations for climate-dependent energy budgets, biogeography and fitness are reviewed and analysed for populations
Oxygen limitation may affect the temperature and size dependence of metabolism in aquatic ectotherms
This model predicts that oxygen limitation is more likely to constrain metabolism in larger, warmer, and active fish, and provides a formal, quantitative framework for predicting both resting and active metabolic rate and hence aerobic scope of aquatic ectotherms.
Climate change effects on fishes and fisheries: towards a cause-and-effect understanding.
This paper tries to establish links between various levels of biological organization by means of addressing the effective physiological principles at the cellular, tissue and whole organism levels.
Consequences of climate-induced low oxygen conditions for commercially important fish
Oxygen availability is key in determining habitat suitability for marine fish. As a result of climate change, low oxygen conditions are predicted to occur more frequently and over a greater

This Review takes a broad view how OCLTT can be looked at as an evolutionary principle that allows a deeper understanding of connectivity and the impacts of climate change in biological systems.
Synergistic impacts of ocean acidification and temperature rise on the physiology of marine invertebrates in a latitudinal cline
With global climate change, ocean warming and acidification occur concomitantly. In this study, we tested the hypothesis that increasing CO2 levels affect the acid–base balance and reduce the
Elevated temperature and acclimation time affect metabolic performance in the heavily exploited Nile perch of Lake Victoria
Upper thermal tolerance limits and metabolic traits of a heavily exploited, tropical freshwater fish (the Nile perch) have high thermal plasticity without incurring major energetic costs, challenging predictions that tropical species have limited thermal Plasticity and that high temperatures will be detrimental because of limitations in AS.
Predicted impacts of climate warming on aerobic performance and upper thermal tolerance of six tropical freshwater fishes spanning three continents
The results show that each species had some ability to perform at temperatures up to 4°C above current maxima, yet also displayed certain areas of concern for their long-term welfare, suggesting the need for more species-specific studies of adaptive capacity to climate change-related challenges.


Climate change and temperature-dependent biogeography: oxygen limitation of thermal tolerance in animals
The capacity of oxygen delivery matches full aerobic scope only within the thermal optimum and at temperatures outside this range, only time-limited survival is supported by residual aerobic scope, then anaerobic metabolism and finally molecular protection by heat shock proteins and antioxidative defence.

Eurythermy, which encompasses cold tolerance, is hypothesized to be the “missing link” between ectothermy and endothermy, and is seen as the single most important reason why metazoan evolution led to life forms with high energy turnover.

The present review attempts to identify the trade-offs involved in adaptation to cold in the light of progress in the physiology of thermal tolerance.
Physiological disturbances at critically high temperatures: a comparison between stenothermal antarctic and eurythermal temperate eelpouts (Zoarcidae)
The data suggest that the southern distribution limit of Zoarces viviparus is correlated with the limit of thermal tolerance, and it can be anticipated that global warming would cause a shift in the distribution of this species.
Climate Change and Distribution Shifts in Marine Fishes
We show that the distributions of both exploited and nonexploited North Sea fishes have responded markedly to recent increases in sea temperature, with nearly two-thirds of species shifting in mean
The warming trend at Helgoland Roads, North Sea: phytoplankton response
We combine the temperature and phytoplankton data from one of the longest aquatic data sets in history, the Helgoland Roads (North Sea, 54°11.3’N, 7°54.0’E) timeseries to evaluate the effects of
