A compilation of TE divergence plots over the evolutionary time scales in selected fish genomes discussed in the text. The S. salar plot (a) shows Tc1-like DNA TEs, with the X-axis showing per cent similarity to the consensus for each family and the Y-axis showing its genome abundance in Mb [15]. The O. mykiss (b) [17] and L. oculatus (c) [18] panels show the canonical RepeatMasker [45] TE landscape divergence plots with Kimura distances on the X-axis and per cent of the genome occupied by each TE superfamily on the Y-axis. The scales on the X-axes differ for (a) vs (b) and (c), thus the S. salar plot was mirrored and stretched to extend the X scale to the limit of detection beyond which no data can be plotted (25% nucleotide divergence, or Kimura distances of 50). Arrows indicate major TE expansions.
