Isolated Lives: The Crisis Mouse That Might Save Itself

On genetic resilience, habitat fragmentation, and why small doesn’t mean doomed

There is a mouse on Callisto Station’s outer agricultural ring — a remnant population, six colonies, maybe three hundred individuals total — that has been declared ‘functionally endangered’ by the Galactic Biodiversity Bureau for the last forty years.

Every few cycles, a GBB committee recommends captive breeding. Every few cycles, the funding gets redirected to something with better press coverage. The Callisto Pocket Mouse (Perognathus callistoensis, if you want to look it up, and you should) just keeps being small and brown and ignored in the thermal-regulated soil between the hydroponic bays.
