1 Entropy production according to circadian cycles. Entropy features [H(x)] of the general tendencies in the normal condition [Temp (°C); see Additional file 1: 2.3 for more detail on the entropy calculation]. Normalized (vertical axis) = standard score (Z calculation), H(x) = entropy production, Temp = temperature (Celsius), circadian points (horizontal axis). See Additional file 1: 2.2.1 for further detail on the results. 2 Circadian and temperature perturbation-dependent influences. The plot on the left illustrates the heat-based relationships between the entropy (horizontal axis) and perturbation (vertical axis) for different circadian points (blue line and dots denote 5:00 A.M.[=AM 5], green line and dots denote 17:00 P.M. [=PM 17]). The plot on the right illustrates the ice-based relationships between the entropy (horizontal axis) and perturbation (vertical axis) for different circadian points. See Additional file 1: 2.2.2 and 2.2.3 for further detail on the results
