Which behavioral adjustment maximizes heat retention when a hibernating marmot's core temperature drops rapidly during late winter?

💡 Explanation

Rapid cooling triggers peripheral vasoconstriction, reducing blood circulation near the skin's surface, thereby minimizing heat loss through the skin because this is a mechanism of retaining heat by limiting radiation . Therefore vasoconstriction results instead of shivering, vasodilation or lowered metabolism, which expend further energy or release more heat.
