Figure 1From: Molecular evolution under increasing transposable element burden in Drosophila: A speed limit on the evolutionary arms raceA) Phylogenetic tree of the Drosophila species used in this study, with TE abundance indicated in Mb. Dots indicate nodes for which ω was estimated on descendant foreground branches. B) TE abundance is correlated with TE family number. Unique, species-specific PILER-DF centroids vs. genomic TE abundance (p = 0.001). r p : Pearson's correlation coefficient. β: regression coefficient (slope).Back to article page
