Sigmoid display of male guppy. Female mating choice may also be influenced by another female's choice. In an experiment, female guppies watched two males, one solitary and the other actively courting another female, and were given a choice between the two. Most females spent a longer time next to the male that was courting. [34]
Guppies are located across several isolated streams in Trinidad and male colour patterns differ geographically. Female guppies have no coloration but their preference for these colour patterns also vary across locations. In a mate choice study, female guppies were shown to prefer males with colour patterns that are typical of their home stream ...
Female guppies tend to exhibit mate-choice copying by employing visual observation of a demonstrator female's mate choice.. Mate-choice copying requires a highly developed form of social recognition by which the observer (i.e. copier) female recognizes the demonstrator (i.e. chooser) female when mating with a target male and later recognizes the target male to mate with it. [4]
However, selection for ornamentation within this species suggests that showy female traits can be selected through either female–female competition or male mate choice. [59] Since carotenoid-based ornamentation suggests mate quality, female two-spotted guppies that develop colorful orange bellies during breeding season are considered ...
These conflicts include mating and fertilization frequency, parental efforts, and power struggles between male and female dominance. [7] The Trinidadian guppy, Poecilia reticulata has a resource-free mating system, meaning males do not provide during mating or defend their territories against other males. [8] Guppies demonstrate one of the ...
In the guppy, Poecilia reticulata, females will copy another female's mate choice if given the opportunity to watch the other female choose. While older females do not copy younger females, younger females will copy older females.
Sometimes, male guppies also try to forcefully mate with Skiffia bilineata (goodeid) females, which resemble guppy females and tend to share the same habitat, even when guppy females are available. A possible explanation for this is the deeper genital cavity of S. bilineata , which stimulates the males more than when mating with guppy females.
The original japan blue wild type guppy was a Poecilia reticulata collected from Lac du Rorata. Lac du Rorota is a reservoir in French Guiana. Karen Koomans received a single male japan blue guppy and crossed it with Cumana Endler females to preserve the strain. Karen Koomans introduced this strain to the hobby as the 'Japan blue wild type guppy'.
