Virtual duck bills demonstrate species coexistence
...ecologists, including Darwin, suggested that ducks coexist because interspecific differences in the spacing of bill lamellae allow each species to consume food particles of different sizes. Research published in the March issue of the American Naturalist by Brent Gurd of Simon Fraser University has demonstra...News tips from the Journal of Neuroscience
