Coercion Experience Enhances Evasion Abilities in Swordtail Females

Autor: Adams, Elena

Coercive mating tactics have been observed in many different species, and are indicative of intense conflict between the sexes— when males and females differ in their reproductive goals, mating strategies which are beneficial to one sex may be detr

Context-dependent preferences vary by multicomponent signals in a swordtail

Autor: Luke Reding, Molly E. Cummings

Publikováno v: Animal Behaviour. 129:237-247

Female mating preferences can be both context dependent and based on the assessment of multicomponent male signals. Here, we assess the social context dependence of female mating preferences for two components of a male's multicomponent signal. We di

Bourgeois and parasitic males produce sperm maximizing either performance or endurance, according to divergent spawning roles.
Males pursuing alternative reproductive tactics have been predicted to face a trade-off between maximizing either swim

Repeatability and consistency of female preference behaviours in a northern swordtail, Xiphophorus nigrensis

Publikováno v: Animal Behaviour. 72:217-224

Informative and reliable measures of mate choice are essential for accurately identifying female preference patterns across species. Here we identify female receptivity behaviours in mate choice experiments in a species of northern swordtails, Xiphop

Rodlet cells in the posterior intestine of embryos and neonates of two poeciliid species

Autor: H. Potter, C. R. Kramer

Publikováno v: Journal of Fish Biology. 62:1211-1216

Rodlet cells occurred in the posterior intestine of embryos and neonates of the swordtail Xiphophorus nigrensis, its hybrids with Xiphophorus pygmaeus and in the platyfish Xiphophorus maculatus. This is the first observation of these enigmatic cells
