Aggressive mating strategies in young adolescent girls
… is the time when humans begin utilizing mating strategies (e.g., flirting, fighting or rumor spreading about competitors) to attract and keep mates. Consistent empirical evidence shows that some adolescent boys are on a developmental pathway in which they utilize aggression and risky …

Extra-pair paternity within the female-defense polygyny of the lizard, Anolis carolinensis: Evidence of alternative mating strategies
… males possible. In the polygynous female-defense mating system of Anolis carolinensis, males compete directly for females through territorial behavior. Inter-male competition is intense due to an average polygyny ratio of 1 male to 3 females despite a 1:1 adult sex ratio. Through high levels of …

Mating dynamics of South African forest millipedes : Centrobolus (Diplopoda: Pachybolidae)
This study focuses on the mating dynamics of South African forest millipedes Centrobolus (Diplopoda: Spirobolida: Pachybolidae). The main objectives were to investigate the two most common mechanisms of sexual selection, sperm competition and cryptic female choice. The approach was to (1) quantify …

Sex in a Lekking Lizard: Hormones, Alternative Strategies, and Mating Success in Marine Iguanas (Amblyrhynchus Cristatus)
… reproductive success associated with alternative strategies. I studied hormonal correlates of alternative phenotypes and mating strategies; which factors affect ""decisions"" about which strategy to use; and diurnal and seasonal changes in hormone levels."

Behavioral and genetic correlates of reproductive success in male addax (Addax nasomaculatus, De Blainville 1816)
… ranging herds of addax to establish the mating strategies male addax pursue to increase their reproductive success. This study demonstrates that addax have the ability to become territorial under certain conditions, possibly due to the high population density and constant resource base as …

Pick-Up lines: To Use a Neg or a Flippant?
… learn how the phenomenon of short- or long-term mating is initiated. By taking into account mating strategies, mate value, attractiveness, and flirting strategies, a pattern of behaviors and reactions may be observed. This study examines perceived pick-up line appropriateness and effectiveness …

Exploitation of nonadditive variance through nonrandom mating
… sires and maternal grandsires (mgs). Current mating programs, utilizing nonadditive genetic variance only by avoiding mating between close relatives to prevent inbreeding depression, could be improved upon by use of predicted combination effects due to nonadditive variation beyond inbreeding. …

Individual reproductive strategies in the dusky warbler (Phylloscopus fuscatus)
… behaviours of both females and males. The mating system of this population is characterised by facultative polygyny (17 per cent of the males mated with more than one female), and by an outstandingly high rate of extra-pair paternity (45 per cent of the offspring was not sired by the social …

The Maintenance of Male Color Polymorphism in Poecilia parae
… five color morphs employ different behavioral mating strategies (hereafter alternative mating strategies, AMSs) to maximize their reproductive success. These AMSs are also accompanied by differences in morphological traits, such as testes investment and sperm morphometry that complement the …

Social context shapes individual variation in behavior, learning, and neural gene expression in a swordtail fish
… a species with three genetically-influenced male mating strategies (courtship display, coercion, and mixed strategy). In males, we found that coercive males are bolder but have decreased spatial cognition abilities compared to mixed-strategy and courting males. In females, we conducted a social …

Oxytocin, Dopamine, and the Neuromodulation of Mating Behavior in C. Elegans
