(Springer) The exchange of information in public toilets is widespread. It also occurs in the world of white-footed sportive lemurs. Only instead of writing on the walls, they use scent-marks in order to communicate with their own kind. In a study published in Springer's journal Behavioral Ecology and Sociobiology, scientists from the German Primate Center have found that the urine left on latrine trees serves as a method to maintain contact with family members.
