In this paper, Sam Steyaert and colleagues quantify spatiotemporal segregation between various reproductive classes of brown bears using resource selection modelling. They find that sexually selected infanticide best explains the observed segregation, and that infanticide risk avoidance can be a very complex and fine scaled spatiotemporal mechanism. The results indicate that females with dependent young probably use human shields to lower the risk for infanticide.
