Study: tadpoles experience morphological changes in response to Roundup

A new study conducted by University of Pittsburgh indicates that the popular weed killer Roundup causes morphological changes in amphibians. In other words, the amphibians are changing shape possibly in adaptation to the weed killer’s stresses.

For this study, three types of tadpoles were used: the leopard frog, American toad and wood frog. The tadpoles were placed in created wetlands with “environmentally relevant” concentrations of Roundup.

Many of the tadpoles’ tail grew to twice their normal length. This is similar to the adaptations developed in response to the stress of predators. The larger tails allow the tadpoles to escape faster.
