Tim McCay and Damhnait McHugh (Biology) and Ahmet Ay (Biology and Mathematics) have received a two-year award of $152,907 for their project 鈥淚nterdisciplinary Approach to Understanding Ongoing Biological Invasions by Crazy Worms (Amynthas) in North America鈥. Earthworms of the genus Amynthas are rapidly invading North America from Asia. These large, lively worms (aka 鈥淐razy Worms鈥) have large effects on the ecosystems they invade, but we know very little about their basic biology and potential for spread.
This project will integrate fieldwork, lab experiments, molecular analyses, and mathematical modeling to reveal the life history and physiological tolerances of these earthworms, reconstruct their historical invasion of North America, and make predictive statements about their spread and impact. The goal is to learn enough about Amynthas to inform management strategies for these invasive species.
