I have chosen two species of
toad as my models.Amphibians
are excellent models for endocrine disruptor study because they have
relatively short larval period and allow for multigenerational studies.Not only do these species of toad
inhabit atrazine-usage areas, but their risk for exposure is heightened by
the ability for contaminants to cross their permeable skin.The oak toad is native to
Florida.It is the smallest toad
in North America
