Which physiological effect occurs when a mammal enters a thermoneutral zone during hibernation?

💡 Explanation

When warmth in thermoneutral zone, brown fat thermogenesis via UCP1 decreases because less heat needs producing metabolically, thus diminishing reliance on non-shivering thermogenesis. Therefore brown fat decreases in activity, as body requires less heat, rather than enhanced respiration/shivering implying cold stress or vasoconstriction, unnecessary at normal temperatures.
