Which physiological change occurs in overwintering squirrels when ambient thermostat temperature rises abruptly, exceeding thermoneutral zone?

💡 Explanation

When ambient temperature exceeds the thermoneutral zone, squirrels use vasodilation, because increased blood flow radiates heat to the environment, reducing core temperature. Therefore, peripheral vasodilation for evaporative cooling results,rather than thermogenesis, BAT upregalation, or immune response, which are associated with retaining body heat rather than dissipating it.
