. Individual male guppies (Poecilia reticulata: Poeciliinae) exhibit two distinct types of mating behaviour: sigmoid displays used in courtship, and gonopodial thrusts used in circumventing female choice. To test how these alternatives are influenced by sexual selection and natural selection, ambient light levels were manipulated to vary potential predation risk, and mating behaviour was examined in relation to male morphology. At high light intensity, larger males displayed significantly less… 
Light environment and mating behavior in Trinidadian guppies (Poecilia reticulata)
Investigation of variation in natural underwater guppy light environments in Trinidad, West Indies found that mating behavior is correlated with both the ‘quantity’ and ‘quality’ of light: light intensity and the proportion of ultraviolet light were negatively related to display rates.
Plasticity in male courtship behaviour as a function of light intensity in guppies
Male mating behaviour in the Trinidadian guppy Poecilia reticulata is phenotypically plastic in response to recent light environment, which may have implications for understanding how animals cope with anthropogenic environmental change.
Male alternative mating behaviour depending on tail length of the guppy, Poecilia reticulata
It is shown that male tail length determines the frequency of these alternative mating behaviour in the guppy, and the greater frequency of sneaking behaviour by males with longer tails to unreceptive females should be adaptive.
Size-dependent male mating tactics and their morphological correlates in Poecilia gillii
Evidence is found for the predicted associations between male size, coloration, morphology and mating behaviour that appear likely to maximize mating success for males of a given body size and phenotype.
Predation risk and alternative mating tactics in male Trinidadian guppies (Poecilia reticulata)

The results are the first to confirm risk-sensitive mating behaviour in free-ranging male guppies within a population, and demonstrate the potential importance of predators in influencing the relative use of alternative mating tactics in this species on a microgeographical scale in the wild.
The Influence of Male Body Size and Social Environment on the Mating Behavior of Phallichthys quadripunctatus (Pisces: Poeciliidae)
Whereas neither size class of P. quadripunctatus males performed courtship displays or altered behavior based on female receptivity, large males performed several reproductive behaviors more frequently than small males.
Individual consistency in exploratory behaviour and mating tactics in male guppies
Although males showed significant consistency in their exploratory and mating behaviour over time, there was no evidence that these traits constituted a behavioural syndrome and the future challenge is to investigate how individual consistency across different environmental contexts relates to male reproductive success.
Male display rate reveals ejaculate characteristics in the Trinidadian guppy, Poecilia reticulata.
This study uncovered a strong correlation between display rate and sperm number in male guppies derived from two wild Trinidadian populations, which indicates that information on the functional fertility of potential mates is available to females and finds a significant relationship between the frequency of sneaky mating and sperm numbers.
Mating and aggressive behaviour of Brachyrhaphis olomina (Cyprinodontiformes: Poeciliidae)
Differences in male behaviour when paired with a female with mature ovum (more mating displays, no agonistic movements) suggest that males detect the female’s reproductive condition from some distance.
Habitat use mediates the conflict of interest between the sexes
