Published: 21 February 2022
...Matthew E. Pamenter ABSTRACT Hypoxia is one of the strongest environmental drivers of cellular and physiological adaptation. Although most mammals are largely intolerant of hypoxia, some specialized species have evolved mitigative strategies to tolerate hypoxic niches. Among the most hypoxia...

..., dropping their body temperature by 23–37°C, while others can only enter shallow torpor (e.g. pigeons, 3–10°C reduction). However, deep torpor in mammals can increase predation risk (unless animals are in burrows or caves), inhibit immune function and result in sleep deprivation, so even for species...

... and placental mammals. The allometric equations for both marsupials and placentals have an explicit, non-zero intercept, but the allometric exponent is higher in the equation for placentals than in that for marsupials. The approach followed here is extraordinarily versatile, and it has wider application...

Because mammals are invariably larger and behaviourally more complex, they are less suited to this type...
