North America saved its bison from extinction. Now scientists face a new threat

Bison numbers have recovered after near extinction, but genetic diversity is now a concern. Fragmented herds lack natural gene exchange, potentially leading to inbreeding over time. New research reveals cattle genes are less widespread in bison than previously thought. Scientists are developing biobanks and IVF to reconnect isolated bison populations. Indigenous communities remain central to conservation efforts and cultural renewal.
