Fig. 3: Genomic consequences of the Alpine ibex recolonization.
From: Purging of highly deleterious mutations through severe bottlenecks in Alpine ibex
a The recolonization history and population pedigree of Alpine ibex. Locations include also zoos and the population Pilatus (pi), which was not sampled for this study. am: Alpi Marittime, gp: Gran Paradiso; ih: Zoo Interlaken Harder; al: Albris; bo: Bire Öschinen; br: Brienzer Rothorn; ob: Oberbauenstock; pl: Pleureur; rh: Rheinwald; wh: Weisshorn; pi: Pilatus; pp: Wildpark Peter and Paul. The gray circle represents a population that was founded from more than one population. Figure elements were modified from Biebach and Keller (2009) with permission. b Principal component analysis of all Alpine ibex individuals included in the study. c Nucleotide diversity per population. d Proportion of the genome within runs of homozygosity (ROH) longer than 2.5 Mb. e Rxy analysis contrasting the strongly bottlenecked Alpi Marittime population with all other Alpine ibex populations across the spectrum of impact categories. Rxy < 1 indicates a relative frequency deficit of the corresponding category in the Alpi Marittime population. Rxy distributions are based on jack-knifing across chromosomes. Circles with a black outline indicate the first three reintroduced populations in Switzerland that were used for all subsequent population reintroductions of Alpine ibex. Colors associate founder and descendant populations. Box plot elements are defined as in Fig. 1. Source data are provided as a Source Data file.
