Phylogenetic independent contrasts between expression level (FPKM) and genomic abundance for gypsy and copia elements exhibiting FPKM ≥1 (see Fig. 2). Each data point represents an individual contrast, with Pearson’s r and P values calculated based on PIC analyses performed for H. agrestis (a), H. carnosus (b) and H. porteri (c)
