Data from: Sneaker males affect fighter male body size and sexual size dimorphism in salmon
Large male body size is typically favored by directional sexual selection through competition for mates. However, alternative male life-history phenotypes, such as "sneakers," should decrease the strength of sexual selection acting on body size of large "fighter" males. We tested...
