As Summer Takes Hold, So Do the Jumping Worms

At the University of Wisconsin-Madison Arboretum, study of Asian jumping worms began after they were discovered on the grounds in 2013. “They may have a cascading, behind-the-scenes impact that might not happen tomorrow, but that will eventually affect other organisms at a higher trophic level,” said Bradley M. Herrick, a plant ecologist and the research program manager at the arboretum.
