Figure 2. Population structure of Hogna maderiana andH. insularum species. a) Discriminant analysis of
principal components (DAPC) for 50 specimens using 865 SNPs set. The
axes represent the first two Linear Discriminants (LD). Dots represent
individuals, and the clusters are presented in different colours.b) Population structure analysis of 50 specimens inferred using
STRUCTURE software based on 865 SNPs for K = 2 and K=3. Each individual
is represented by a horizontal bar proportionally coloured according to
the probability of assignment to each cluster. c) Co-ancestry
matrix based on fineRADstructure analysis of ddRAD-seq loci. The
dendogram depicts clustering of individual samples based on the pairwise
matrix of co-ancestry coefficients. Pairwise coefficients of co-ancestry
are colour-coded from low (yellow) to high (blue) according to the scale
shown on the right. Square black box demarcations identify individuals
showing higher co-ancestry.
