摘要：We examine the toxicity of a commercial formulation of Round-Up to wood frog (Rana sylvatica) tadpoles. All tadpoles exposed to nominal concentrations ≥ 0.00098% glyphosate died within 24 h. However, tadpoles exposed to concentrations ≤ 0.00049% showed high survivorship. Our results suggest that any direct application of this formulation of Round-Up to aquatic ecosystems could have an impact on amphibian larvae, especially in shallow water.
