(PhysOrg.com) -- Working with the University of Southern Maine, Northwest State Community College researchers Lisa Aschemeier and Christine Maher have proven what might seem common sense; that some animals react to the warning signals of animals of other species. In an article published in the Journal of Mammalogy, the two describe how they recorded the alarm calls of eastern chipmunks (Tamias striatus) and woodchucks (Marmota monax), rodents with several common enemies and found that both responded to some extent, to each others calls.
