Apparent Stability

In sperm-dependent sexual/asexual mating systems, male mate choice is critical for understanding the mechanisms behind apparent stability observed in natural populations. The gynogenetic Amazon molly ( Poecilia formosa ) requires sperm from sexual males (e.g. Poecilia latipinna ) to trigger embryogenesis, but inheritance is strictly maternal. Consequently, males should try to avoid or reduce the cost of mating with asexuals. We investigated male mate choice by documenting the presence of sperm in natural populations and found that a higher proportion of sexual females had sperm than asexuals. In addition, among those females that had sperm, sexuals had more sperm than asexuals. Our results hint at a role for male mate choice as a stabilizing factor in such systems.

AbstractThe all-female fish Poecilia formosa uses sperm of Poecilia latipinna or P. mexicana for its gynogenetic reproduction. Normally, P. formosa lives in sympatry with only one of these species. Near Tampico, Mexico, one population of P. formosa is living in sympatry with both sperm-donor species. In the present study, using animated videos as stimuli, we examined whether P. formosa from Tampico show a sexual preference for males of one of the two species. We raised P. formosa females with males of P. latipinna or P. mexicana only, and as a control with males of both species simultaneously. We found that previous experience affects mating preferences in P. formosa. Females tend to prefer males of the species they were raised with.
