Biologists and ecologists monitor wildlife to learn more about their behaviors, but tracking small creatures can be challenging, time-consuming and costly. Through a National Science Foundation grant, a multidisciplinary team at Northern Arizona University—led by Michael Shafer, associate professor of mechanical engineering; Carol Chambers, professor of wildlife ecology; and Paul Flikkema, professor of electrical engineering—has developed technology… Read more
Evolutionary biologists have long puzzled over how new traits emerge in nature, largely because much of the evolutionary information available is from the distant past. To learn more about how genes influence evolution, these researchers study organism phenotypes—the observable characteristics of an organism that are influenced by genetics and environment—and… Read more
