Nonlethal parasites reduce how much their wild hosts eat, leading to ecosystem effects
Research from the Living Earth Collaborative highlights the cascading consequences of common parasitic infections. Although many of these infections are not lethal, they can still impact health or animal behavior, leading hosts to eat less vegetation. The study led by biologist Amanda Koltz in Arts & Sciences is published in the Proceedings of the National Academy of Sciences.

Class Acts: Nathan Stanfield
Misi-ziibi means “great river” in the Anishinaabe language. For the Native peoples of upper Minnesota, misi-ziibi referred to the long, 1,300-mile stretch flowing south of the Crow Wing River, past present-day St. Louis and into the Gulf of Mexico. But the name was not the only thing taken from the Anishinaabe, argues Nathan Stanfield, who is about to earn his master’s degree in architecture.
