What critical refuge mechanism do diurnal *Xerus rutilus* use against extreme temperatures?
Answer
Extensive burrow systems
To cope with the harsh thermal extremes characteristic of arid and semi-arid regions where *Xerus rutilus* thrives, these diurnal squirrels rely heavily on constructing and inhabiting extensive burrow systems. These underground networks function as vital microclimates, offering substantial refuge from both the scorching heat experienced above ground during the day and potentially cooler temperatures at night. This reliance on sophisticated burrowing behavior is intertwined with their social structure and their need for protection against surface predators, making the burrow structure foundational to their survival strategy.
