Infanticide as Sexual Conflict: Coevolution of Male Strategies and Female Counterstrategies

摘要: One of the earliest recognized forms sexual conflict was infanticide by males, which imposes serious costs on female reproductive success. Here I review two bodies evidence addressing coevolved strategies males and females. The original selection hypothesis arguing that improves male mating success accelerating return females to fertilizable condition has been generally supported in some taxa-notably, primates, carnivores, rodents, cetaceans-but not other taxa. result recent research implicate selective benefits various taxa from insects birds mammals, such as acquisition breeding status or improvement condition. In cases, however, adaptive significance remains obscure. second body data is arguably most important research: clarifying possible counterstrategies infanticide. These potential span diverse biological systems, ranging behavior (e.g., polyandrous mating), physiology Bruce effect), individual maternal aggression), social association with coalitionary defenders either sex). Although much be studied, these current provide compelling sexually antagonistic coevolution surrounding phenomenon Language: en
