Ground Squirrel Hibernation: An Adaptive Strategy For Survival

Ground squirrels hibernate as an adaptive strategy to survive harsh conditions. Physical adaptations, such as insulation and environmental cues, trigger torpor, a dormant state with reduced body temperature and physiological adjustments. The hibernaculum provides insulation, while body temperature drops drastically. Physiological changes include decreased heart and breathing rates, energy expenditure, and oxygen utilization. Hibernation allows ground squirrels to conserve energy during food scarcity and extreme cold, ensuring their survival in challenging environments.
