Genotypic and genetic descriptors
To account for the genotypic composition and genetic state of populations, we computed two indices describing the number and distribution of genotypes (genotypic richness \(R\) and slope of the size distribution of lineages Pareto β, Arnaud-Haond et al., 2007) and two genetic descriptors referring to intra-individual genetic variation (as the first four moments of the inbreeding coefficient\(F_{\text{IS}}\) distribution; Stoeckel & Masson, 2014) and LD (as the summarised unbiased multi-locus LD \(\overset{\overline{}}{r_{D}}\); Agapow & Burt, 2001).
