Mouthparts of southern leopard frog, Lithobates sphenocephalus, tadpoles not affected by exposure to a formulation of glyphosate
Abstract
This study evaluated the impacts of Roundup® on tadpole mouthpart damage as a mechanism for reduced growth and developmental rates in Lithobates sphenocephalus (Southern leopard frog) tadpoles. We did not find evidence that Roundup® damages larval mouthparts, nor was there a significant relationship between mouthpart damage and either body condition or developmental rate. However, the highest concentration of Roundup® significantly stunted development compared to all other treatments. Although we observed a significant effect of Roundup® on developmental rate, we conclude that mouthpart damage is likely not a mechanism for this life history response. © Springer Science+Business Media New York 2013.
