(CNN) – Atrazine, a weed killer widely used in the Midwestern United States and other agricultural areas of the world, can chemically “castrate” male frogs and turn some into females, according to a new study.
New research suggests the herbicide may be a cause of amphibian declines around the globe, said biologists at the University of California-Berkeley, who conducted the study. The findings are being published this week in the journal Proceedings of the National Academy of Sciences.
Atrazine, one of the world’s most widely used pesticides, wreaks havoc with the sex lives of adult male frogs, emasculating three-quarters of them and turning one in 10 into females, according to a new study by University of California, Berkeley, biologists.
The 75 percent that are chemically castrated are essentially “dead” because of their inability to reproduce in the wild, reports UC Berkeley’s Tyrone B. Hayes, professor of integrative biology.
