“…Griffon vulture species is considered to be socially monogamous and once formed couples stay together 56,57 , although rare cases of extra-pair copulation within the same colony have been observed 58 but never confirmed by genetic analyses 59 . Furthermore, it has a wide dispersion and migrates throughout the Mediterranean.…”

The Griffon vulture was once a widespread species across the region of Southeast Europe, but it is now endangered and in some parts is completely extinct. In the Balkan Peninsula the largest Griffon vulture inland population inhabits the territory of Serbia. We present, for the first time, the genetic data of this valuable population that could be a source for future reintroduction programs planned in South-eastern Europe. To characterize the genetic structure of this population we used microsatellite markers from ten loci. Blood samples were collected from 57 chicks directly in the nests during the ongoing monitoring program. We performed a comparative analysis of the obtained data with the existing data from three native populations from French Pyrenees, Croatia, and Israel. We have assessed the genetic differentiation between different native populations and determined the existence of two genetic clusters that differentiate the populations from the Balkan and Iberian Peninsulas. Furthermore, we analysed whether the recent bottleneck events influenced the genetic structure of the populations studied, and we found that all native populations experienced a recent bottleneck event, and that the population of Israel was the least affected. Nevertheless, the parameters of genetic diversity suggest that all analysed populations have retained a similar level of genetic diversity and that the Griffon vulture population from Serbia exhibits the highest value for private alleles. The results of this study suggest that the Griffon vulture populations of the Balkan Peninsula are genetically differentiated from the populations of the Iberian Peninsula, which is an important information for future reintroduction strategies.

Although senescence has been described for various fitness components in a wide range of animal species, few studies have studied senescence in long‐lived species, and little is known about its interactions with varying environmental conditions. Using a 32 year capture–mark–recapture dataset on the griffon vulture Gyps fulvus, we examined the demographic patterns of actuarial senescence and the patterns of year‐to‐year variation in survival rates. We found a significant, surprisingly late, decrease of annual survival probabilities from the age of 28 years onward and divided individual lifetimes into to three categories (juvenile, mid‐age and senescent birds). In agreement with the environmental canalization hypothesis, our analyses uncovered 1) higher temporal variation of annual survival probabilities in both the juvenile and senescent age classes compared to the mid‐age class and 2) low sensitivity of the population growth rate to the survival of both the juvenile and senescent age classes. Our results further suggested that the temporal variation in the survival of senescent birds might be related to intra‐annual changes in air temperature amplitudes. Finally, using population dynamics modeling, we revealed contrasting effects of the inclusion of the senescent age class on predicted population growth, depending on how survival rates were modeled. Altogether, our results demonstrate the existence of a class of senescent birds that exhibit distinct demographic properties compared to juvenile and mid‐age classes.

“…This suggests a low contribution of extra-pair paternity to these intra- and inter-nest kinship relationships. Although extra-pair copulation has been reported at low frequency in the Egyptian vulture ( Donázar, Ceballos & Tella, 1994 ), the contribution to extra-pair paternity remains generally unexplored in vultures ( Le Gouar et al, 2011 ). Our results showed exclusive full-sib relationships between nestlings from the same nest and cohort (broods of two siblings).…”

Genetic signatures of population bottlenecks, relatedness, and inbreeding highlight recent and novel conservation concerns in the Egyptian vulture

The assessment of temporal variation in genetic features can be particularly informative on the factors behind demography and viability of wildlife populations and species. We used 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 stable over a period of twelve years despite the decline in census and effective population sizes in the last decades. A relatively high proportion of nestlings from different and distant territories showed high relatedness in each study year. We also found support for an increasing impact of severe recent (contemporary) rather than distant (historical) past demographic bottlenecks, and the first evidence of inbred mating between full siblings coinciding with lethal malformations in offspring. The inbred nestling with feather malformations was positive to beak and feather disease virus recorded for the first time in this species. These results alert on recent and novel threats potentially affecting health and reducing the adaptive potential of individuals in this threatened species.
