Standard examples in biological game theory are introduced. The degree of cooperation at evolutionary stability is analysed in models that deal with situations such as the Prisoner’s Dilemma, the Tragedy of the Commons and the conflict of interest between parents over care of their common young. Several models of aggressive interactions are treated in this book. In this chapter the Hawk–Dove game, which is the simplest of these models, is analysed. Further models in the chapter deal with the situation in which individuals vary in their fighting ability and the situation in which information about the opponent is available before an individual decides whether to be aggressive. The problem of the allocation of resources to sons versus daughters has played a central role in biological game theory. This chapter introduces the basic theory, as well as a model in which the environmental temperature affects the development of the sexes differentially, so that at evolutionary stability the sex of offspring is determined by this temperature. Coordination games, alternative mating tactics, dispersal to avoid kin competition, and the idea that signals can evolve from cues are also introduced.

Mating Tactics

We examined the diving behaviour of breeding male grey seals (Halichoerus grypus) at Sable Island, Nova Scotia, from 1997 to 2001. The proportion of time spent at sea varied between 0 and 78% (N = 30). Males engaged in deep (43.4 ± 3.3 m (mean ± SE), N = 27) diving, and these dives were clustered into bouts, which mostly occurred during long trips (62.2 ± 14.7 h). We suggest that males spent time foraging during deep dives. Shallow diving (5.9 ± 0.1 m, N = 27) accounted for 40.8% of dives, which were also clustered into bouts that mostly occurred during short trips (2.1 ± 0.37 h). We suggest that shallow diving comprised a suite of behaviours, but included little foraging behaviour. Phenotypic traits had little influence on diving behaviour. Further work is required to understand the extent to which foraging behaviour enhances reproductive success, and whether shallow diving is a component of the mating tactics of male grey seals at Sable Island.

Alternative mating tactics are a widespread feature in insects. A typical form of alternative mating behaviour is being a sneaker in the vicinity of a territorial male. Such nonterritorial males have lower mating success, but they may benefit from lower energetic costs and decreased predation risk. In this study, we examined whether nonterritorial male damselflies Calopteryx virgo (L., 1758) are subject to lower predation risk than territorial males. To distinguish predation from other sources of mortality, we used models. The experiment consisted of dried male damselflies settled into the typical perching positions of territorial and nonterritorial males. Also the spatiotemporal patterns of predation risk were studied. The survival of nonterritorial male models was consistently higher than that of territorial male models, which can be attributed to different predation risk. Survival of the models was lower in the presence of avian predators and in large populations. Survival rates were affected by habitat type but did not change during the season. We conclude that nonterritorial male damselflies are less vulnerable to predation and that there may be a trade-off which could potentially make the fitness of sneakers equal to that of territorial males.
