“…Sexual selection in fishes is usually the result of an interaction between male-male competition and female choice, as shown through both field observations and laboratory experiments (Fuller, 2001;McGhee et al, 2007). An understanding of this complex interaction first requires assessment of the characteristics of the breeding system of a species in the field or in natural-like situations.…”

“…Killifishes (Cyprinodontidae, Fundulidae) provided good models for study of the expression of male competitive tactics and the interaction between male competition and female choice (Kodric-Brown, 1986, 1988Fuller, 2001;McGhee et al, 2007;Itzkowitz, 2002, 2004).…”

“…The level of activity of the males has been shown to be the only predictor of spawning success in Lucania goodei (McGhee et al, 2007), suggesting that the activity of the males and male-male competition are important components of sexual selection in these types of breeding systems.…”

Abstract. This work provides an ethogram of male reproductive behavior in the most widespread Mediterranean killifish, the South European toothcarp Aphanius fasciatus. The ethogram was obtained by video-recording the behavior of breeding groups under aquarium conditions. The behavioral analysis revealed the existence of seven behavioral states, with the expression of different forms of male-male competition: single and multiple courtship, single and multiple spawning, aggression, homosexual courtship, and postmating cannibalism. These behaviors were organized into sequences that followed a first-order Markov chain. Single courtship was the most prevalent behavior, but more than one male, from two to five, could participate simultaneously in courtship and spawning. Results suggested that the breeding system is based on mate monopolization, with high levels of sperm competition and parasitic spawning. Results are discussed in light of the current literature on alternative mating tactics and male-male competition in teleost fishes.

“…As males can fertilise offspring at a higher rate than females, intrasexual selection is thought to be stronger among males (Andersson 1994). There are two critical issues for understanding sexual selection: first, the two components of sexual selection may act in concert, independently or in opposition (Berglund et al 1996;McGhee et al 2007); and secondly, both 'ornaments and armaments' are based upon multiple cues, as reviewed by Ptacek (2000). In fishes, SSTs include morphological structures, sexual displays, colouration and pheromonal signals that are usually combined in a multivariate set of cues (Ptacek 2000).…”

“…The interaction between male-male competition and female choice recently has been investigated by McGhee et al (2007), using a killifish (the fundulid Lucania goodei) breeding system as a study model. Although the male interference was crucial, especially at an early phase determining the initial mating pool, the female decision exerted control in terms of the latency of spawns, number of visits and released eggs (McGhee et al 2007).…”

Some relationships between the relative size of secondary sexual traits and male mating success were investigated in the killifish Aphanius fasciatus (Nardo, 1827). The relative ability of a male to compete with another male for access to a ripe female was related to the relative size of male sexual traits by means of a behavioural experiment under controlled laboratory conditions. Furthermore, the covariation in the expression of sexual traits was analysed from a sample of field-collected males. Results of the behavioural experiment showed that male dominance and success were positively related to the relative height of the dorsal fin, but not to the pattern of vertical bars along body sides. Within the analysed male population, males with larger fins tended to have thinner bars, whereas there was no statistically significant correlation with bar number or with bar asymmetry. The results were discussed in terms of advantages conferred by larger dorsal fins in killifish breeding systems, and developmental constraints defining a multiple set of traits correlated to male quality were also hypothesised.

Exaggerated evolution of male armaments via male–male competition

Males usually compete to gain access to prospective mates. Through this male–male competition, superior males have a higher chance of passing on their traits to the next generation of male offspring. One category of male traits is armaments, which are weapons used during competition, for example, the chelae of fiddler crabs and the antlers of deer. One consequence of intrasexual selection is the exaggerated evolution of armaments, which can be limited by trade‐offs, such as trade‐offs with male body size. Here, we formulate a game‐theoretic sexual selection model to explore the exaggerated evolution of armaments through male–male competition. The model is used to determine how competition affects the evolution of an armament that is subject to trade‐offs. Our simulation can be used to support the exaggerated evolution hypothesis, that is, male–male competition escalates the rate of evolution of armaments.
