“…It is however surprising that this signal is strong enough to override species recognition. The importance of chemical signals for species and mate recognition in this genus is weH documented (e. g. LILEY 1966;GANDOLFI 1969;CROW & LILEY 1979;MEYER & LILEY 1982), especiaHy in P. mexicana (ZEISKE 1968(ZEISKE , 1971PARZEFALL 1969PARZEFALL , 1970PARZEFALL , 1973. It is important to note that this signal is not the same in the whole family Poeciliidae.…”

Male Mate Choice in Mixed Bisexual/Unisexual Breeding Complexes of Poecilia (Teleostei: Poeciliidae)

The livebearing all‐female fish Poecilia formosa reproduces by gynogenesis, a modified form of parthenogenesis. P. formosa forms at least two breeding complexes: in its northern range it exists sympatrically with Poecilia latipinna and in its southern range with Poecilia mexicana. Differences between these complexes and their possible origin are discussed. Embryogenesis is triggered by sperm of males of these closely related sympatric species. Because inheritance is strictly maternal, from the male point of view energy and time invested are totally lost. In this study we wanted to elucidate whether males are able to distinguish between conspecific and parasitic females. It could be shown that males are able to distinguish females optically, but that this ability was obscured as soon as chemical and/or tactile contact was possible. Furthermore, we found that females in an attractive phase of their sexual cycle are always preferred, regardless of species. This is possibly the mechanism by which parasitic females obtain the matings they need to reproduce.

“…This water was chosen because of the suspected presence of pheromones released during birth, which are stimulatory to male courtship behavior [27,28]. Nonreceptive females were chosen to maximize the similarity of the female response to different males during measurement.…”

Despite the enormous volume of research concerning the various effects of chemicals with endocrine-disrupting properties in fish, there is still very little evidence that endocrine disruption can adversely affect individual fertility and, hence, pose problems for the population. In the present study, guppies (Poecilia reticulata) were fed with the anti-androgenic fungicide vinclozolin at concentrations ranging from 1.8 to 180 mg/kg from 8-14 wk of age. Male sperm count and the intensity of his sexual display behavior were significantly reduced in treatment groups, which was in line with the results of previous studies. Here, we show further that these impairments translate into reduced fertility, measured as the size of the female's first clutch. Also, this reduced fertility was correlated to the male sperm count, but not to the intensity of the male sexual display. Finally, by crossing exposed with unexposed animals, we show that the adverse effect of vinclozolin on reproduction is mediated through the male alone.

“…Earlier experiments showed no role for far-eld chemical communication in P. mexicana (Cave molly: Zeiske, 1968; cave entrance population: Wenzel, 1997). Other poeciliid shes are known to use water soluble pheromones for species recognition (Crapon de Caprona & Ryan, 1990;McLennan & Ryan, 1997 for Xiphophorus) or for the determination of the female's sexual cycle (Liley, 1966;Crow & Liley, 1979;Meyer & Liley, 1982;Brett & Grosse, 1982 for Poecilia).…”

Animals colonizing lightless subterranean habitats can no longer rely on visual signals to find mating partners. In the present study, we investigated the ability of males to recognize females in two surface and a cave dwelling population of a livebearing fish, Poecilia mexicana. In surface populations males discriminated between sexes with visual plus non-visual cues available and with visual stimuli only. In the cave form the ability to discriminate with solely visual stimuli is lacking. In all three populations, males did not recognize females in darkness (infrared observations), suggesting that sex recognition via far-field communication is lacking in surface and cave dwelling P.mexicana. Different preferences in large and small males to stay near a female or a male stimulus fish probably reflect differences concerning a trade-off between sexual and aggressive behaviour.
