Obviously this is not normal. |
Our impact is measured in an insignificant way. I now measure my impact differently. |
We demonstrated that a realistic pesticides mixture (based on a mixture applied to an actual field) at low, ecologically relevant concentrations can have dramatic effects on amphibian development and growth and ultimately, we predict, survivorship. |
