Evolution LettersAbstract Sexual conflict frequently gives rise to adaptations that increase male reproductive success at the expense of harming females (“male harm”) and decreasing population growth. Studying the ecology of male harm is paramount to understand how sexual conflict unfolds in nature, and its consequences for populations viability.
