Victorian koalas are regaining genetic diversity through population growth, defying extinction fears.
A new study of koala genetics reveals that population growth can drive genetic recovery even after severe historical bottlenecks, challenging the idea that low genetic diversity equals high extinction risk.
Researchers analyzing 418 koalas found that Victorian populations, once considered genetically compromised, are rebuilding diversity through expansion and recombination, while some genetically diverse northern populations are declining.
The findings show that population trends matter more than static genetic measures, offering hope for species recovery with proper conservation support.
