Which risk increases when an arctic ground squirrel enters its periodic interbout arousal during hibernation?

💡 Explanation

When arousal happens from hibernation in the Arctic ground squirrel, vasodilation occurs because thermoregulation activates to increase blood flow and metabolic rate. This leads to behavioral activity which increases predation risk for the animal. Therefore, higher predation risk results rather than, dehydration, hypothermia, or acidosis that do not directly linked to behavioral activity during arousal episodes.
