ABSTRACT Increasing water temperatures owing to anthropogenic climate change are predicted to negatively impact the aerobic metabolic performance of aquatic ectotherms. Specifically, it has been hypothesized that thermal increases result in reductions in aerobic scope (AS), which lead to decreases in energy available for essential fitness and performance functions. Consequences of warming are anticipated to be especially severe for warm-adapted tropical species as they are thought to have…

Thermal acclimation offsets the negative effects of nitrate on aerobic scope and performance

TLDR
Nitrate exposure increases the susceptibility of fish to acute changes in temperature by lowering aerobic scope and performance, but thermal phenotypic plasticity can override these potentially detrimental effects.

Cardiac plasticity influences aerobic performance and thermal tolerance in a tropical, freshwater fish at elevated temperatures

TLDR
Elevated temperature induces cardiac remodeling in Nile perch, establishing mechanistic links between cardiac plasticity, metabolic performance and thermal tolerance in a fish faced with climate-change-related stressors and providing evidence that plasticity in cardiac capacity may be one mechanism for coping with climate change.

Thermal conditions during embryogenesis influence metabolic rates of juvenile brown trout Salmo trutta

. The projected climate change and increase in thermal conditions in northern latitudes over the next 60 yr has the potential to alter the metabolic scope and potential fi tness of aquatic ectotherms.

Thermal tolerance and hypoxia tolerance are associated in blacktip reef shark (Carcharhinus melanopterus) neonates

TLDR
Thermal tolerance is associated with hypoxia tolerance in blacktip reef shark (Carcharhinus melanopterus) neonates and the association between thermal tolerance and hypoxIA tolerance suggests a common mechanism warranting further investigation.

Divergence in aerobic scope and thermal tolerance is related to local thermal regime in two populations of introduced Nile perch (Lates niloticus).

TLDR
Results suggest phenotypic divergence in thermal tolerance between these two introduced populations in a direction consistent with an adaptive response to local thermal regimes, and effects of temperature acclimation were more pronounced in the Lake Victoria population.

Molecular and physiological responses predict acclimation limits in juvenile brook trout (Salvelinus fontinalis).

TLDR
How molecular and physiological responses predict acclimation limits in a freshwater fish is demonstrated as the brook trout in the present study had a limited ability to acclimate to temperatures beyond 20°C.

Differential Effects of Food Restriction and Warming in the Two-Spotted Goby: Impaired Reproductive Performance and Stressed Offspring

Climate change is a growing threat to marine organisms and ecosystems, and it is already modifying ocean properties by, for example, increasing temperature and decreasing pH. Increasing water

Molecular and physiological responses predict acclimation limits in juvenile brook trout (Salvelinus fontinalis)

TLDR
It is suggested that brook trout may have a limited ability to acclimate to temperatures >20°C and increases in temperatures beyond 20°C may impact brook Trout populations.

The effects of predicted climate change conditions on tropical sharks

Myriad anthropogenic impacts drive declines in global shark populations; yet, the consequences of a newly recognised threat, global climate change, are poorly understood. This thesis tested the

Aerobic scope does not predict the performance of a tropical eurythermal fish at elevated temperatures

TLDR
Results reveal limited power of the OCLTT hypothesis in predicting optimal temperatures and effects of climate warming on juvenile barramundi and suggest AS may be dynamically modulated independent of temperature to accommodate the requirements of daily life.

Temperature acclimation rate of aerobic scope and feeding metabolism in fishes: implications in a thermally extreme future

TLDR
Temperature acclimation dynamics of SMR, maximum metabolic rate, AS and the specific dynamic action of feeding (SDA) were determined in shorthorn sculpin after transfer from 10°C to 16°C, demonstrating a considerable capacity for metabolic thermal compensation.

Acclimation to predicted ocean warming through developmental plasticity in a tropical reef fish

TLDR
Fish acclimated to elevated water temperatures were smaller and in poorer condition than fish reared at present day temperatures, suggesting that even with adequate acclimation there will be significant consequences for future populations of tropical fishes caused by global warming.

Aerobic scope fails to explain the detrimental effects on growth resulting from warming and elevated CO2 in Atlantic halibut

TLDR
It is shown that aerobic scope and cardiac performance of Atlantic halibut (Hippoglossus hippoglossu) increase following 14–16 weeks exposure to elevated temperatures and even more so in combination with CO2-acidified seawater, demonstrating that oxygen uptake is not the limiting factor for growth performance at high temperatures.

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

TLDR
It is shown in the eelpout, Zoarces viviparus, a bioindicator fish species for environmental monitoring from North and Baltic Seas, that thermally limited oxygen delivery closely matches environmental temperatures beyond which growth performance and abundance decrease, which will be the first process to cause extinction or relocation to cooler waters.

Antarctic fish can compensate for rising temperatures: thermal acclimation of cardiac performance in Pagothenia borchgrevinki

TLDR
In spite of living in a highly stenothermal cold environment, P. borchgrevinki demonstrated the capacity to thermally acclimate cardiac function to elevated temperatures, thereby allowing the maintenance of factorial scope and the support of aerobic swimming at higher temperatures.

Oxygen delivery does not limit thermal tolerance in a tropical eurythermal crustacean

TLDR
This study shows that the oxygen transport capacity is maintained at high temperatures, and that other mechanisms, such as protein dysfunction, are responsible for the loss of ecological performance at elevated temperatures.

Climate change and temperature-dependent biogeography: oxygen limitation of thermal tolerance in animals

TLDR
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.

Thermal sensitivity does not determine acclimation capacity for a tropical reef fish.

TLDR
This research indicates that acclimation ability may vary greatly between populations and that understanding such variation will be critical for predicting the impacts of warming environmental temperatures.
