James Stroud, assistant professor in the School of Biological Sciences, joined Fox Weather to talk about the "falling iguana alerts" now issued by the National Weather Service in Miami when temperatures dip unseasonably lower during the winter, causing the large lizards to fall out of Florida trees. Stroud, an evolutionary ecologist, spoke of his lab's studies to find out whether iguanas are adapting to colder temperatures brought on by climate change, or whether genetic factors are involved. Iguanas, normally found in hotter Central and South American climates, are considered an invasive species for Florida.
