Question 2 Why do small Arctic mammals enter hibernation whereas larger mammals stay active during the winter months? smaller mammals have a low metabolic rate so hibernate to maintain this low need for energy and fuel. smaller mammals lose heat faster due to their small body size and high surface area: volume ratio. smaller mammals consume less oxygen per kilogram than a larger mammal and hibernate in order to maintain this low consumption rate. O smaller mammals hibernate in order to increase metabolic demand for the winter months.
