Rapidly reproducing mutant ‘super pigs’ found in Fukushima nuclear disaster zone

Researchers found hybrid pigs near Fukushima are rapidly expanding after escaped domestic pigs interbred with wild boars.

The hybrids inherited a faster, year-round reproductive cycle, helping them spread in abandoned post-disaster areas.

The study highlights how habitat abandonment after the 2011 nuclear disaster can accelerate invasive hybrid populations.

The findings raise new wildlife management and conservation concerns in Japan and beyond.
