Fig 1.
Map of the Iberian Peninsula showing the current Iberian ibex (Capra pyrenaica) distribution (grey colour) with the three studied populations highlighted in red.
Both the C. p. pyrenaica and C. p. lusitanica subspecies are extinct.
Table 1.
Number of alleles, standardized allelic richness, mean observed heterozygosity (HO), expected heterozygosity (HE) and FIS (estimate of deviation from random mating) per population of the two studied C. pyrenaica subspecies corresponding to three Iberian ibex populations in Spain.
Table 2.
Matrix of population pairwise FST (below diagonal) and significance level (above diagonal) for each pairwise comparison of the three Iberian ibex populations from Spain.
Fig 2.
Results of the DAPC analysis of the three main ibex populations in Spain when the number of genetic clusters is 3 (K = 3).
1: Sierra de Gredos (C. p. victoriae). 2: Maestrazgo Natural Park (C. p. hispanica). 3: Sierra Nevada Natural Space (C. p. hispanica).
Fig 3.
Bar plots of the proportion of individual variation in 333 Iberian ibex from the three main ibex populations in Spain assigned to given genetic clusters in INSTRUCT, with two (A: K = 2), three (B: K = 3) and four (C: K = 4) clusters. Each cluster is represented by a different colour.
Fig 4.
Unrooted dendrogram showing the genetic relationships (genetic divergence as a percentage %) in the three studied Iberian ibex populations based on Nei’s standard genetic distance [32].
Table 3.
Parameters and results for bottleneck analyses used to detect significant reductions in effective population size in Iberian ibex from different populations in Spain.
The parameters for heterozygosity (expected heterozygosity excess, heterozygosity excess and heterozygosity deficiency) refer to the number of loci.
