In this 2014 image from a remote camera trap provided by Taal Levi, a black bear eats devil's club berries near Haines, Alaska. A study of bears and berries has determined that the big animals are the main dispersers of fruit seeds in southeast Alaska. The study by Oregon State University researchers says it's the first instance of a temperate plant being primarily dispersed by mammals through their excrement rather than by birds.
