Table 1.
Locations of study ponds, contamination level (sum of toxic units, STU, see Eq. 2), number of captured toad pairs and number of toad pairs that spawned
| Pond | Coordinates (WGS84) | STU | Number of toad pairs | |
|---|---|---|---|---|
| Captured | Spawned | |||
| A | 49.25475, 7.96182 | −4.48 | 12 | 11 |
| B | 49.23830, 7.99002 | −3.48 | 13 | 11 |
| C | 49.20329, 8.20917 | −3.09 | 15 | 13 |
| D | 49.21830, 8.04944 | −2.25 | 14 | 14 |
| E | 49.18898, 8.03709 | −1.75 | 8 | 5 |
Pond letters indicate increasing STU. Since no pesticides were detected in pond A, its STU was calculated based on the use of 1/10 of the minimum TU observed in the sites with detected concentrations (for rationale s. Schäfer et al. 2011)
