With only two living females, the Northern white rhino is functionally extinct. Now, scientists are attempting to use assisted reproductive technology to save itby Philip Ball / July 5, 2018 / Leave a comment
The Northern white rhinoceros of the grasslands and savannah of southern Africa has been hunted to extinction. But modern assisted reproduction technology might yet rescue it.
That’s according to a new study which demonstrates a dramatic possibility for developments in embryology to transform nature conservation.
The population of Northern white rhinos has been tiny since the 1980s, rarely exceeding 30 or so.
Currently, there are just two alive. Both were born in captivity and belong to the Dvůr Králové Zoo in the Czech Republic but are kept under armed guard in the Ol Pejata Conservancy of Kenya.
Both, however, are females—a mother and daughter The last surviving male died of natural causes in March. So there is no way, now, for the species to persist by natural means; it is “functionally” extinct.
The reason for that is poaching. Rhino horn fetches huge prices on the black market, and conservators have been taking to sawing off the horns of rhinos under sedation to eliminate poachers’ key motivation.
