Toad-fed	1, 2, 4, 6/7, 8, 9, 10, 11, 13, 14, 15, 17 (n = 4)	1, 2, 3, 4, 5, 6/7, 8, 9, 10, 11, 13, 14, 15, 17 (n = 4)	1, 2, 3, 4, 5, 6/7, 8, 10, 11, 13, 14, 15, 17 (n = 4)	1, 6/7, 8, 10, 11, 13, 14, 15 (n = 4)	1, 2, 3, 5, 6/7, 8, 10, 11, 13, 14, 15, 17 (n = 4)	1, 2, 3, 4, 5, 6/7, 8, 10, 11, 13, 14, 15 (n = 4)

N represents the number of hatchlings per clutch, whereas n indicates the number of individuals analyzed. Bufadienolides present in the majority of individuals per group are identified by compound numbers (see electronic supplementary material, Supporting Information Fig. S1b, for structures of compounds). The bufadienolide present in the largest quantity per group is underlined.
