A Girl and Her Dog
BBC Earth News has posted a wonderful slide show of Carly Vynne—a graduate student at the Center for Conservation Biology at the University of Washington—and her scat-detector dog, Mason, in Emas National Park in Brazil. Mason and other dogs have been trained to find the scats of the unique wildlife in the park, including giant armadillo, giant anteater, maned wolf, tapir, and jaguar. The scats provide an enormous amount of vital information on population size and health for these threatened species.
