Sexual difference in signal-receiver coevolution
Article Abstract:
The response to a male signal in the northern swordtail fish, Xiphophorus, depends on the sex of the receiver. The signal, a pattern of vertical bars helps in attracting females and discouraging rival males. The male response and male signal coevolve more closely when compared to the response of the female to the same male signal. Congruency between the male response and signal occurs in X. multilineatus and X. nigrensis whereas the female response and the same signal are congruent in X. multilineatus.

The influence of experience on mating preferences of the gynogenetic Amazon molly
Article Abstract:
A study was conducted on the mating preferences of the female gynogenetic Amazon molly. Species of molly used in the experiment included the Poecilia formosa, Xiphophorus multilineatus and Poecilia latipinna. Results showed that experience can influence a female's mating preference, whereby sexually mature females may switch their preferences due to individual interactions with males. Moreover, the change in preferences may be due to the degree of male sexual behavior.
