Reproductive performance in houbara bustard is affected by the combined effects of age, inbreeding and number of generations in captivity

Abstract Although captive breeding programs are valuable for conservation, they have been shown to be associated with genetic changes, such as adaptation to captivity or inbreeding. In addition, reproductive performance is strongly age-dependent in most animal species. These mechanisms that potentia...
