Document Summary
When animal wakens from torpor, mr increases. Hibernation = long-term torpor (several weeks few months) Postural changes (how the animal positions itself in env"t ie wrt to vessels to the periphery) orientation of sun like camels) Insulation adjustments (adjusting whether hair standing straight up or whether it"s matted down horizontally will effects its insulation properties) Tnz shown in flat area (within this range, the animal doesn"t use any metabolic energy to maintain its body temp: slide 15. Zmr see that basal mr increases in this zone (if it exceeds the lct, enter zmr) linear increase in mr with decreasing temp. Beyond this, if the animal persists for any time beyond this, it becomes. Correction: vcu should read uct if exceed uct, have zone of active heat dissipation that increases mr linearly with increasing temp (anything beyond this, the animal enters into hypothermia) hypothermic.
