TLDR
Evolutionary games in which two males mate with the same female are examined by using an evolutionarily stable strategy (ESS) approach, which depends critically on the information available to the two competitors, and whether they occupy roles (of first or second to mate) randomly or non-randomly.

TLDR
Ejaculation strategies for cases when an opportunist male ‘steals’ a mating with the female of a paired male are examined, an evolutionary game of competitive ejaculation in which two (or more) males mate with the same female.
Potential Reproductive Rates and the Operation of Sexual Selection
TLDR
This framework for relating sex differences in mating competition to the operational sex ratio, potential reproductive rates, and parental expenditure differs from Triver's concept of the relation between parental investment and mating competition in three ways.

TLDR
It is argued that ejaculate economic theory represents a powerful heuristic to explain the diversity in ejaculate traits at multiple levels: across species, across males and within individual males.
Punishment in animal societies
TLDR
Punishing strategies are used to establish and maintain dominance relationships, to discourage parasites and cheats, to discipline offspring or prospective sexual partners and to maintain cooperative behaviour.
