Figure 2:

Dispersal responses of five EPN species after exposure to their own macerate. Bars show means +/- SEM. Symbols over bars indicate species that showed statistically significant increases in dispersal after conspecific macerate exposure († = P < 0.10, ** = P < 0.01).

Figure 3:

Dispersal responses of five EPN species after exposure to macerate derived from Heterorhabditis bacteriophora-infected cadavers. Bars show means ± SEM. Symbols over bars indicate species that showed statistically significant changes in dispersal after conspecific macerate exposure (**= P < 0.01). Relative to H. bacteriophora, increasing distance to the right along the graph represents increasing phylogenetic distance, according to Spiridonov and Subbotin (2016).
