| Sumario: | The assessment of temporal variation in genetic features can be particularly informativeon the factors behind demography and viability of wildlife populations and species. Weused molecular methods to evaluate neutral genetic variation, relatedness, bottlenecks,and inbreeding in a declining population of Egyptian vulture (Neophron percnopterus)in central Spain. The results show that the genetic diversity remained relatively stableover a period of twelve years despite the decline in census and effective population sizesin the last decades. A relatively high proportion of nestlings from different and distantterritories showed high relatedness in each study year. We also found support for anincreasing impact of severe recent (contemporary) rather than distant (historical) pastdemographic bottlenecks, and the first evidence of inbred mating between full siblingscoinciding with lethal malformations in offspring. The inbred nestling with feathermalformations was positive to beak and feather disease virus recorded for the first timein this species. These results alert on recent and novel threats potentially affecting healthand reducing the adaptive potential of individuals in this threatened species. |
