A capitivating and beautifully photographed Scientists in the Field title about a man trying to discover the effects pesticides have on frogs and, in turn, on us.When Tyrone Hayes was growing up in South Carolina, he didn t worry about pesticides. He just liked to collect frogs. Tyrone s interest in science led him to Harvard University, and though he struggled at first, he found his calling in the research lab of an amphibian scientist. Meanwhile, scientists discovered that all around the globe, frogs were dying. The decline has many causes, including habitat loss and disease. Tyrone discovered that the most commonly used pesticide in the United States, atrazine, may also play a role. Tyrone tested atrazine on frogs in his lab at Berkeley. He found that the chemical caused some of the male frogs to develop into bizarre half-male, half-female frogs. What was going on? That s what Tyrone wants to find out.
