Data from: Population genomics analyses of European ibex species show lower diversity and higher inbreeding in reintroduced populations
- 负责人：
- DOI：
- doi:10.5061/dryad.n276d
- 摘要：
- runs of homozygosity showed recent inbreeding primarily in individuals of reintroduced populations. We showed that despite the rapid census recovery, Alpine ibex carry

- 摘要：
- ng winters can dramatically obscure key processes driving subpopulation size. Further, novel population models which integrate capture–mark–recapture, census
