Figure legends
Figure 1 Sampling sites and introduction pathways ofCarassius auratus in this study. The figures in brackets below
site names represents the number of diploid and triploid samples. The
two dotted lines represents main transportation routes (Qinghai-Tibet
Highway and Sichuan-Tibet Highway) connecting Tibet and its east.
Figure 2 The maximum-likelihood phylogenetic trees based on
mitogenome sequences of diploids (a) and triploids (b).
Figure 3 Principal component analysis based on genomic
LD-pruned SNPs for diploids (a), triploids (b) and all samples (c).
Figure 4 Population structure analysis based on genomic
LD-pruned SNPs for diploids (a) and triploids (b).
Figure 5 Genome-wide genetic diversity of invasive and nativeCarassius auratus at individual (a) and population (b) levels.
The p value of the paired-sample t -test in figure a was
showed for each pair-wise comparison. The light red and light blue bars
figure b represented the invasive and native populations, respectively.
Figure 6 The genome-wide distribution of ROHs detected in
invasive diploids (above) triploids (below).
Figure 7 Reconstruction of the population size histories with
the SMC++ method.
Figure 8 Detection of putative signatures of selective sweeps
between invasive and source populations by sliding-window analysis of
the F ST and |XP-EHH| values in
diploids (a and b) and triploids (c and d). Dashed lines indicated
genome-wide 1% outlier cut-off.
