Its mating system relies on heterospecific matings with males of closely related sexual species. In mixed popu- lations, males mate with conspecific sexual females and heterospecific asexual females. Such matings are not isolated dyadic interactions but rather elements of a communication net- work, because multiple females can observe these interactions. This is the only known case of heterospecific mate-copying and, thus, a system in which the potential for mate-copying could be influenced by the presence of another species. Here we show that mate-copying is exhibited by the sexual species P. mexicana and P. latipinna , and the asexual P. formosa . Both sexual and asexual females copy each other’s mate choice decisions in sympatry, but females from allopatric populations do not show heterospecific TI - Geographic variation in female mate-copying in the species complex of a unisexual fish, Poecilia formosa JF - Behaviour DO - 10.1163/156853908784474533 DA - 2008-01-01 UR - https://www.deepdyve.com/lp/brill/geographic-variation-in-female-mate-copying-in-the-species-complex-of-7yEaMPqQOJ SP - 1041 EP - 1064 VL - 145 IS - 8 DP - DeepDyve ER -
