ANIMALS - Researchers find mother beetles eat young that beg too much

A pair of researchers from the University of Edinburgh has found that a certain type of beetle mother engages in offspring cannibalism when pestered too much. In their paper published in Behavioral Ecology, Clare Andrews and Per Smiseth describe two experiments they conducted to learn more about the behavior mechanisms that are involved in mediating the resolution of parent-offspring conflict.
