See Full Interview Transcript

Dr. Dean Williams, a biology professor at TCU in Fort Worth, has spent many years studying horned lizards, and trying to understand the reasons behind their decline. Many of his research projects have focused on remnant populations of the lizards in small south Texas towns. There, he has found that protecting a vital mix of open and bushy areas provides the small patches of sun and shade that enable horned lizards to keep a safe body temperature.
