Feral pig-boar hybrids in Fukushima's exclusion zone rapidly spread due to high fertility, diluting domestic DNA but boosting population growth.
After the 2011 Fukushima disaster, escaped domestic pigs interbred with wild boar in the evacuated zone, creating hybrids that thrive despite radiation.
A 2015–2018 study of 201 animals found the pigs’ year-round breeding cycle sped up hybrid generation turnover, causing rapid dilution of domestic DNA, especially through maternal lines.
While pig mitochondrial DNA faded after about five generations, the hybrid population grew quickly due to persistent high fertility.
Researchers say this mechanism may explain invasive species surges where feral pigs and wild boar overlap, offering new insights for global wildlife management.
Los híbridos salvajes de cerdos y jabalíes en la zona de exclusión de Fukushima se extendieron rápidamente debido a la alta fertilidad, diluyendo el ADN doméstico pero impulsando el crecimiento de la población.
