Correlation of TEs with biotic and abiotic factors. a) This panel displays the results of phylogenetic generalized least-squares (PGLS) regressions between TE percentages and median latitude b) This panel portrays the PGLS regression results between TE percentage and body size (log-transformed). Lastly, c) depicts PGLS results between TE abundance and the maximum habitat depth of the species. The colors and shapes of each data point on the plot are defined in the key.
