Appendix G. Summary of the results of post hoc statistical analyses of larval salamander traits, comparing the three salamander treatments (i.e., large-variation, large-variation giant-removal, and small-variation treatments).
Summary of the results of post hoc statistical analyses of larval salamander traits, comparing the three salamander treatments (i.e., large-variation, large-variation giant-removal, and small-variation treatments). Significant values are in bold (significant level was adjusted using sequential Bonfferoni methods with significant value P = 0.05).
