"Not unexpectedly, Relyea found that the insecticides reduced the diversity and number of insects. Interestingly, he found that very low doses of the insecticides increased the survival of tadpoles, probably because of the high mortality of the dragonflies, beetles and hemipterans, all tadpole predators. Perhaps most surprisingly, Relyea discovered that Roundup, designed to kill plants, exterminated two frog species, and nearly exterminated a third, reducing tadpole "richness" by 70 percent. Many of the deaths occurred in the first 24 hours after the addition of the Roundup."
