Transposable Element Diversity and Activity Patterns in Neotropical Salamanders.

ABSTRACT: Transposable elements (TEs) compose a substantial proportion of the largest eukaryotic genomes. TE diversity has been hypothesized to be negatively correlated with genome size, yet empirical demonstrations of such a relationship in a phylogenetic context are largely lacking. Furthermore, the most abundant type of TEs in genomes varies across groups, and it is not clear if there are patterns of TE activity consistent with genome size among different taxa with large genome sizes. We use low-coverage sequencing of 16 species of Neotropical salamanders, which vary ∼7-fold in genome size, to estimate TE relative abundance and diversity for each species. We also compare the divergence of copies of each TE superfamily to estimate patterns of TE activity in each species. We find a negative relatio
