Evolution of alternative mating tactics: conditional versus mixed strategies

Plaistow, Stewart J.; Johnstone, Rufus A.; Colegrave, Nick - In: Behavioral Ecology 15 (2004) 4, pp. 534-542

Intrasexual polymorphisms have evolved in a wide range of organisms. Most of them have been interpreted as the product of conditional strategies in which the tactic an individual adopts is determined by some aspect of state (e.g., age, size, condition). However, there are a few examples that...
