Article Synopsis
- Small populations, whether in captivity or the wild, are facing negative effects from isolation and inbreeding due to habitat loss and overexploitation.
- This study focuses on the genomic differences between managed and unmanaged populations of the scimitar-horned oryx, revealing that unmanaged groups have higher inbreeding rates and a greater burden of harmful genetic mutations.
- The findings highlight the importance of genetic management to preserve genetic diversity in vulnerable species, especially in light of large-scale reintroduction efforts.
Threatened species are frequently patchily distributed across small wild populations, ex situ populations managed with varying levels of intensity and reintroduced populations. Best practice advocates for integrated management across in situ and ex situ populations. Wild addax () now number fewer than 100 individuals, yet 1000 of addax remain in ex situ populations, which can provide addax for reintroductions, as has been the case in Tunisia since the mid-1980s.

However, they are also vulnerable to the negative impacts of inbreeding, selection and drift. Genetic information is therefore considered a critical aspect of conservation management.
