It is well documented that females play a prominent role in the sexual selection behavior of guppies. Working within the lab in the BNR building, our experiment sought to determine whether the presence of multiple females would, as a result of being within a more competitive environment, affect the sexual selection behavior of female guppies. As we wanted our test to be within a larger environmental context, we decided to use wild type males. One tank had one male on either side with one female in the middle, while the other tank had one male on either side and 3 females in the middle. Female glass tapping behavior against either the right or left glass pane was our measure of female interest. Guppies, male and female, were selected at random. We predicted that females, in the presence of other females, would be more compelled to pursue males and instances of glass tapping would increase.
