Physiological basis for high CO2 tolerance in marine ectothermic animals: pre-adaptation through lifestyle and ontogeny?
TLDR
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. Expand
Swimming performance in Atlantic Cod (Gadus morhua) following long-term (4-12 months) acclimation to elevated seawater P(CO2).
TLDR
Results point at an adjustment of enzymatic activity to cope with the CO2 induced acid-base load at 0.6 kPa P(CO2) while under milder hypercapnic conditions the 'standard' Na+/K+-ATPase capacity might still be sufficient to maintain acid- base status. Expand
Trade‐Offs in Thermal Adaptation: The Need for a Molecular to Ecological Integration*
TLDR
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. Expand
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 populationsExpand
Acclimation of ion regulatory capacities in gills of marine fish under environmental hypercapnia.
TLDR
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. Expand
Exploring Uncoupling Proteins and Antioxidant Mechanisms under Acute Cold Exposure in Brains of Fish
TLDR
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. Expand
Mitochondrial mechanisms of cold adaptation in cod (Gadus morhua L.) populations from different climatic zones
TLDR
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. Expand
Thermal sensitivity of uncoupling protein expression in polar and temperate fish.
TLDR
The results are indicative of a significant role of fish UCP in thermal adaptation of fish mitochondria in the temperature-dependent setting of energy turnover in animals (and their mitochondria). Expand
Elevated seawater PCO₂ differentially affects branchial acid-base transporters over the course of development in the cephalopod Sepia officinalis.
TLDR
The hypothesis that the energy budget of adult cephalopods is not significantly compromised during long-term exposure to moderate environmental hypercapnia is supported, however, the downregulation of ion regulatory and metabolic genes in late-stage embryos, taken together with a significant reduction in somatic growth, indicates that cepinghalopod early life stages are challenged by elevated seawater Pco(2).

Mitochondrial Function in Antarctic Nototheniids with ND6 Translocation
TLDR
The translocation of ND6 is interpreted as functionally neutral but the change in amino acid sequence as adaptive and supportive of cold stenothermy in Antarctic nototheniids, and an enhanced sensitivity to ocean warming can be deduced. Expand
