Physiological basis for high CO2 tolerance in marine ectothermic animals: pre-adaptation through lifestyle and ontogeny?
This paper attempts to summarize some ontogenetic and lifestyle traits that lead to an increased tolerance towards high environmental pCO2, and suggests that compensation of extracellular acid-base status in turn may be important in avoiding metabolic depression.
Swimming performance in Atlantic Cod (Gadus morhua) following long-term (4-12 months) acclimation to elevated seawater P(CO2).
Trade‐Offs in Thermal Adaptation: The Need for a Molecular to Ecological Integration*
This effort illustrates the need for an overarching concept of thermal adaptation that encompasses molecular, organellar, cellular, and whole‐organism information as well as the mechanistic links between fitness, ecological success, and organismal physiology.
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…

Results indicate shifting acclimation patterns between short- and long-term CO(2) exposures and upregulation of NBC1 on long timescales stresses the importance of this transporter in the hypercapnia response of marine teleosts.

Increased in vivo half‐lives of σS and the RpoS742::LacZ hybrid protein (also a substrate for RssB‐dependent proteolysis) are demonstrated in acetyl phosphate‐free (pta–ackA) deletion mutants, even though no sensor kinase was eliminated.
Exploring Uncoupling Proteins and Antioxidant Mechanisms under Acute Cold Exposure in Brains of Fish
Data suggest that PPARs and UCPs are involved in the alterations observed in zebrafish brain after exposure to 18°C, and stimulation of the PPAR-UCP axis may help to prevent oxidative damage and to maintain metabolic balance and cellular homeostasis in the brains of ectothermic zebra fish upon cold exposure.

A molecular network is identified, which responds sensitively to warming beyond the realized ecological niche, and the shift from lipid to carbohydrate stores and usage may support warm hardiness, as the latter sustain anaerobic metabolism and may prepare for hypoxemic conditions that would develop upon warming Beyond the present acclimation temperature.

Comparison of functional levels and transcript levels in white muscle and liver may reflect genetic differentiation at functional sites, in line with genetic differences between the two populations previously established by non-coding genetic markers.
