Web4 de abr. de 2024 · our model suggests that the energy costs of thermoregulation and flight are similar in magnitude and may impose, respec-tively, upper and lower bounds on S-MR (Fig. 2D). Based on the premise that evolution favors morphologies that minimize energy costs such as those of locomotion and thermoregulation (37, 41), we predict … WebThe model was subjected to a simple evolutionary procedure, by iteratively substituting the physiologies of individuals that fail to balance the costs of thermoregulation (by huddling in groups ...
