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.

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.

Acclimation of ion regulatory capacities in gills of marine fish under environmental hypercapnia.

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.

Regulation of RssB‐dependent proteolysis in Escherichia coli: a role for acetyl phosphate in a response regulator‐controlled process

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.

Thermal acclimation in Antarctic fish: transcriptomic profiling of metabolic pathways.

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.

Mitochondrial mechanisms of cold adaptation in cod (Gadus morhua L.) populations from different climatic zones

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.
