Abstract

Thermodynamic analyses are performed to determine the effects of global warming on information transmittance in the squid giant axon. Squids are cold-blooded animals and their body temperature is the same as that of the environment. Modelling showed that at 6.3°C energy cost, exergy destruction and entropy generation were 1.77 × 10–10 kJ/cm2, 3.49 × 10–9 kJ/cm2, and 1.25 × 10–11 kJ/K cm2, respectively. Entropy generation decreased with temperature increase, implying that living became easier for the squid. Thermodynamic analyses performed in this study may help to explain why the squid populations thrive with global warming.
